From 2.2 to 2.3¶
PHP Version¶
PHP 5.5 has reached end of life in July 2016. To ensure that Elgg sites are secure, we now require PHP 5.6 for new installations.
Existing installations can continue using PHP 5.5 until Elgg 3.0.
In order to upgrade Elgg to 2.3 using composer while using PHP 5.5, you may need to use --ignore-platform-reqs
flag.
Deprecated APIs¶
- Registering for
to:object
hook by the extender name: Useto:object, annotation
andto:object, metadata
hooks instead.ajax_forward_hook()
: No longer used as handler for “forward”,”all” hook. Ajax response is now wrapped by theResponseFactory
ajax_action_hook()
: No longer used as handler for “action”,”all” hook. Output buffering now starts before the hook is triggered inActionsService
elgg_error_page_handler()
: No longer used as a handler for “forward”,<error_code> hooksget_uploaded_file()
: Use new file uploads API insteadget_user_notification_settings()
: UseElggUser::getNotificationSettings()
set_user_notification_setting()
: UseElggUser::setNotificationSetting()
pagesetup, system
event: Use the menu or page shell hooks instead.elgg.walled_garden
JavaScript is deprecated: Useelgg/walled_garden
AMD module instead.elgg()->getDb()->getTableprefix()
: Useelgg_get_config('dbprefix')
.- Private
update_entity_last_action()
: Refrain from manually updating last action timestamp.- Setting non-public
access_id
on metadata is deprecated. See below.get_resized_image_from_existing_file()
: Useelgg_save_resized_image()
.get_resized_image_from_uploaded_file()
: Useelgg_save_resized_image()
in combination with upload API.get_image_resize_parameters()
will be removed.elgg_view_input()
: Useelgg_view_field()
. Apologies for the API churn.
Deprecated Views¶
resources/file/world
: Use theresources/file/all
view instead.resources/pages/world
: Use theresources/pages/all
view instead.walled_garden.js
: Use theelgg/walled_garden
module instead.
New API for page and action handling¶
Page handlers and action script files should now return an instance of \Elgg\Http\ResponseBuilder
.
Plugins should use the following convenience functions to build responses:
elgg_ok_response()
sends a 2xx response with HTML (page handler) or JSON data (actions)elgg_error_response()
sends a 4xx or 5xx response without content/dataelgg_redirect_response()
silently redirects the request
New API for working with file uploads¶
elgg_get_uploaded_files()
- returns an array of Symfony uploaded file objectsElggFile::acceptUploadedFile()
- moves an uploaded file to Elgg’s filestore
New API for manipulating images¶
New image manipulation service implements a more efficient approach to cropping and resizing images.
elgg_save_resized_image()
- crops and resizes an image to preferred dimensions
New API for events¶
elgg_clear_event_handlers()
- similar toelgg_clear_plugin_hook_handlers
this functions removes all registered event handlers
New API for signing URLs¶
URLs can now be signed with a SHA-256 HMAC key and validated at any time before URL expiry. This feature can be used to tokenize action URLs in email notifications, as well as other uses outside of the Elgg installation.
elgg_http_get_signed_url()
- signs the URL with HMAC keyelgg_http_validate_signed_url()
- validates the signed URLelgg_signed_request_gatekeeper()
- gatekeeper that validates the signature of the current request
Extendable form views¶
Form footer rendering can now be deferred until the form view and its extensions have finished rendering. This allows plugins to collaborate on form views without breaking the markup logic.
elgg_set_form_footer()
- sets form footer for deferred renderingelgg_get_form_footer()
- returns currently set form footer
Metadata access_id
¶
It’s now deprecated to create metadata with an explicit access_id
value other than ACCESS_PUBLIC
.
In Elgg 3.0, metadata will not be access controlled, and will be available in all contexts. If your plugin relies on access control of metadata, it would be wise to migrate storage to annotations or entities instead.
New API for extracting class names from arrays¶
Similar to elgg_extract()
, elgg_extract_class()
extracts the «class» key (if present), merges into existing class names, and always returns an array.
Notificaciones¶
- A high level
'prepare','notification'
hook is now triggered for instant and subscription notifications and can be used to alter notification objects irrespective of their type.'format','notification:<method>'
hook is now triggered for instant and subscription notifications and can be used to format the notification (e.g. strip HTML tags, wrap the notification body in a template etc).- Instant notifications are now handled by the notifications service, hence almost all hooks applicable to subscription notifications also apply to instant notifications.
elgg_get_notification_methods()
can be used to obtain registered notification methods- Added
ElggUser::getNotificationSettings()
andElggUser::setNotificationSetting()
Entity list functions can output tables¶
In functions like elgg_list_entities($options)
, table output is possible by setting
$options['list_type'] = 'table'
and providing an array of table columns as $options['columns']
.
Each column is an Elgg\Views\TableColumn
object, usually created via methods on the service
elgg()->table_columns
.
Plugins can provide or alter these factory methods (see Elgg\Views\TableColumn\ColumnFactory
).
See the view admin/users/newest
for a usage example.
Inline tabs components¶
Inline tabs component can now be rendered with page/components/tabs
view. The components allows to switch between pre-poluated and ajax-loaded.
See page/components/tabs
in core views and theme_sandbox/components/tabs
in developers plugin for usage instructions and examples.
API to alter registration and login URL¶
elgg_get_registration_url()
should be used to obtain site’s registration URLelgg_get_login_url()
should be used to obtain site’s login URLregistration_url, site
hook can be used to alter the default registration URLlogin_url, site
hook can be used to alter the default login URL
Support for fieldsets in forms¶
elgg_view_field()
replaceselgg_view_input()
. It has a similar API, but accepts a single array.elgg_view_field()
supports#type
,#label
,#help
and#class
, allowing unprefixed versions to be sent to the input view$vars
.- The new view
input/fieldset
can be used to render a set of fields, each rendered withelgg_view_field()
.
From 2.1 to 2.2¶
Deprecated APIs¶
elgg.ui.river
JavaScript library: Remove calls toelgg_load_js('elgg.ui.river')
from plugin code. Updatecore/river/filter
andforms/comment/save
, if overwritten, to require component AMD moduleselgg.ui.popupOpen()
andelgg.ui.popupClose()
methods inelgg.ui
JS library: Useelgg/popup
module instead.lightbox.js
library: Do not useelgg_load_js('lightbox.js');
unless your code references deprecatedelgg.ui.lightbox
namespace. Useelgg/lightbox
AMD module instead.elgg.embed
library andelgg.embed
object: Do not useelgg_load_js('elgg.embed')
. Useelgg/embed
AMD module instead- Accessing
icons_sizes
config value directly: Useelgg_get_icon_sizes()
can_write_to_container()
: UseElggEntity::canWriteToContainer()
Deprecated Views¶
elgg/ui.river.js
is deprecated: Do not rely on simplecache URLs to work.groups/js
is deprecated: Usegroups/navigation
AMD module as a menu item dependency for «feature» and «unfeature» menu items instead.lightbox/settings.js
is deprecated: UsegetOptions, ui.lightbox
JS plugin hook ordata-colorbox-opts
attribute.elgg/ckeditor/insert.js
is deprecated: You no longer need to include it, hook registration takes place inelgg/ckeditor
moduleembed/embed.js
is deprecated: Useelgg/embed
AMD module.
Added elgg/popup
module¶
New elgg/popup module can be used to build out more complex trigger-popup interactions, including binding custom anchor types and opening/closing popups programmatically.
Added elgg/lightbox
module¶
New elgg/lightbox module can be used to open and close the lightbox programmatically.
Added elgg/embed
module¶
Even though rarely necessary, elgg/embed
AMD module can be used to access the embed methods programmatically. The module bootstraps itself when necessary and is unlikely to require further decoration.
New API for handling entity icons¶
ElggEntity
now implements\Elgg\EntityIcon
interfaceelgg_get_icon_sizes()
- return entity type/subtype specific icon sizesElggEntity::saveIconFromUploadedFile()
- creates icons from an uploaded fileElggEntity::saveIconFromLocalFile()
- creates icons from a local fileElggEntity::saveIconFromElggFile()
- creates icons from an instance ofElggFile
ElggEntity::getIcon()
- returns an instanceofElggIcon
that points to entity icon location on filestore (this may be just a placeholder, useElggEntity::hasIcon()
to validate if file has been written)ElggEntity::deleteIcon()
- deletes entity iconsElggEntity::getIconLastChange()
- return modified time of the icon fileElggEntity::hasIcon()
- checks if an icon with given size has been createdelgg_get_embed_url()
- can be used to return an embed URL for an entity’s icon (served via /serve-icon handler)
User avatars are now served via serve-file
handler. Plugins should start using elgg_get_inline_url()
and note that:
/avatar/view
page handler and resource view have been deprecated/mod/profile/icondirect.php
file has been deprecatedprofile_set_icon_url()
is no longer registered as a callback for"entity:icon:url","user"
plugin hook
Group avatars are now served via serve-file
handler. Plugins should start using elgg_get_inline_url()
and note that:
groupicon
page handler (groups_icon_handler()
) has been deprecated/mod/groups/icon.php
file has been deprecated
File entity thumbs and downloads are now served via serve-file
handler. Plugins should start using elgg_get_inline_url()
and elgg_get_download_url()
and note that:
file/download
page handler and resource view have been deprecatedmod/file/thumbnail.php
file has been deprecated- Several views have been updated to use new download URLs, including:
mod/file/views/default/file/specialcontent/audio/default.php
mod/file/views/default/file/specialcontent/image/default.php
mod/file/views/default/resources/file/view.php
mod/file/views/rss/file/enclosure.php
Removed APIs¶
Just a warning that the private entity cache functions (e.g. _elgg_retrieve_cached_entity
) have been removed. Some plugins may have been using them. Plugins should not use private APIs as they will more often be removed without notice.
Improved elgg/ckeditor
module¶
elgg/ckeditor module can now be used to add WYSIWYG to a textarea programmatically with elgg/ckeditor#bind
.
From 2.0 to 2.1¶
Deprecated APIs¶
ElggFile::setFilestore
get_default_filestore
set_default_filestore
elgg_get_config('siteemail')
: Useelgg_get_site_entity()->email
- URLs starting with
/css/
and/js/
:Use elgg_get_simplecache_url()
elgg.ui.widgets
JavaScript object is deprecated byelgg/widgets
AMD module
Application::getDb()
changes¶
If you’re using this low-level API, do not expect it to return an Elgg\Database
instance in 3.0. It now
returns an Elgg\Application\Database
with many deprecated. These methods were never meant to be made
public API, but we will do our best to support them in 2.x.
Added elgg/widgets
module¶
If your plugin code calls elgg.ui.widgets.init()
, instead use the elgg/widgets module.
From 1.x to 2.0¶
Elgg can be now installed as a composer dependency instead of at document root¶
That means an Elgg site can look something like this:
settings.php
vendor/
elgg/
elgg/
engine/
start.php
_graphics/
elgg_sprites.png
mod/
blog
bookmarks
...
elgg_get_root_path
and $CONFIG->path
will return the path to the application
root directory, which is not necessarily the same as Elgg core’s root directory (which
in this case is vendor/elgg/elgg/
).
Do not attempt to access the core Elgg from your plugin directly, since you cannot rely on its location on the filesystem.
In particular, don’t try load engine/start.php
.
// Don't do this!
dirname(__DIR__) . "/engine/start.php";
To boot Elgg manually, you can use the class Elgg\Application
.
// boot Elgg in mod/myplugin/foo.php
require_once dirname(dirname(__DIR__)) . '/vendor/autoload.php';
\Elgg\Application::start();
However, use this approach sparingly. Prefer Encaminamiento instead whenever possible as that keeps your public URLs and your filesystem layout decoupled.
Also, don’t try to access the _graphics
files directly.
readfile(elgg_get_root_path() . "_graphics/elgg_sprites.png");
Use Vistas instead:
echo elgg_view('elgg_sprites.png');
Cacheable views must have a file extension in their names¶
This requirement makes it possibile for us to serve assets directly from disk for performance, instead of serving them through PHP.
It also makes it much easier to explore the available cached resources by navigating to dataroot/views_simplecache and browsing around.
- Bad:
my/cool/template
- Good:
my/cool/template.html
We now cache assets by "$viewtype/$view"
, not md5("$viewtype|$view")
,
which can result in conflicts between cacheable views that don’t have file extensions
to disambiguate files from directories.
Dropped jquery-migrate
and upgraded jquery
to ^2.1.4¶
jQuery 2.x is API-compatible with 1.x, but drops support for IE8-, which Elgg hasn’t supported for some time anyways.
See http://jquery.com/upgrade-guide/1.9/ for how to move off jquery-migrate.
If you’d prefer to just add it back, you can use this code in your plugin’s init:
elgg_register_js('jquery-migrate', elgg_get_simplecache_url('jquery-migrate.js'), 'head');
elgg_load_js('jquery-migrate');
Also, define a jquery-migrate.js
view containing the contents of the script.
JS and CSS views have been moved out of the js/ and css/ directories¶
They also have been given .js and .css extensions respectively if they didn’t already have them:
Old view | New view |
---|---|
js/view |
view.js |
js/other.js |
other.js |
css/view |
view.css |
css/other.css |
other.css |
js/img.png |
img.png |
The main benefit this brings is being able to co-locate related assets.
So a template (view.php
) can have its CSS/JS dependencies right next to it
(view.css
, view.js
).
Care has been taken to make this change as backwards-compatible as possible, so you should not need to update any view references right away. However, you are certainly encouraged to move your JS and CSS views to their new, canonical locations.
Practically speaking, this carries a few gotchas:
The view_vars, $view_name
and view, $view_name
hooks will operate on the
canonical view name:
elgg_register_plugin_hook_handler('view', 'css/elgg', function($hook, $view_name) {
assert($view_name == 'elgg.css') // not "css/elgg"
});
Using the view, all
hook and checking for individual views may not work as intended:
elgg_register_plugin_hook_handler('view', 'all', function($hook, $view_name) {
// Won't work because "css/elgg" was aliased to "elgg.css"
if ($view_name == 'css/elgg') {
// Never executed...
}
// Won't work because no canonical views start with css/* anymore
if (strpos($view_name, 'css/') === 0) {
// Never executed...
}
});
Please let us know about any other BC issues this change causes. We’d like to fix as many as possible to make the transition smooth.
fxp/composer-asset-plugin
is now required to install Elgg from source¶
We use fxp/composer-asset-plugin
to manage our browser assets (js, css, html)
with Composer, but it must be installed globally before installing Elgg in order
for the bower-asset/*
packages to be recognized. To install it, run:
composer global require fxp/composer-asset-plugin
If you don’t do this before running composer install
or composer create-project
,
you will get an error message:
[InvalidArgumentException]
Package fxp/composer-asset-plugin not found
List of deprecated views and view arguments that have been removed¶
We dropped support for and/or removed the following views:
- canvas/layouts/*
- categories
- categories/view
- core/settings/tools
- embed/addcontentjs
- footer/analytics (Use page/elements/foot instead)
- groups/left_column
- groups/right_column
- groups/search/finishblurb
- groups/search/startblurb
- input/calendar (Use input/date instead)
- input/datepicker (Use input/date instead)
- input/pulldown (Use input/select instead)
- invitefriends/formitems
- js/admin (Use AMD and
elgg_require_js
instead of extending JS views)- js/initialise_elgg (Use AMD and
elgg_require_js
instead of extending JS views)- members/nav
- metatags (Use the “head”, “page” plugin hook instead)
- navigation/topbar_tools
- navigation/viewtype
- notifications/subscriptions/groupsform
- object/groupforumtopic
- output/calendar (Use output/date instead)
- output/confirmlink (Use output/url instead)
- page_elements/contentwrapper
- page/elements/shortcut_icon (Use the “head”, “page” plugin hook instead)
- page/elements/wrapper
- profile/icon (Use
elgg_get_entity_icon
)- river/object/groupforumtopic/create
- settings/{plugin}/edit (Use plugins/{plugin}/settings instead)
- user/search/finishblurb
- user/search/startblurb
- usersettings/{plugin}/edit (Use plugins/{plugin}/usersettings instead)
- widgets/{handler}/view (Use widgets/{handler}/content instead)
We also dropped the following arguments to views:
- «value» in output/iframe (Use «src» instead)
- «area2» and «area3» in page/elements/sidebar (Use «sidebar» or view extension instead)
- «js» in icon views (e.g. icon/user/default)
- «options» to input/radio and input/checkboxes which aren’t key-value pairs will no longer be acceptable.
All scripts moved to bottom of page¶
You should test your plugin with the JavaScript error console visible. For performance reasons, Elgg no longer
supports script
elements in the head
element or in HTML views. elgg_register_js
will now load all
scripts at the end of the body
element.
You must convert inline scripts to AMD or to external scripts loaded with
elgg_load_js
.
Early in the page, Elgg provides a shim of the RequireJS require()
function that simply queues code until
the AMD elgg
and jQuery
modules are defined. This provides a straightforward way to convert many inline
scripts to use require()
.
Inline code which will fail because the stack is not yet loaded:
<script>
$(function () {
// code using $ and elgg
});
</script>
This should work in Elgg 2.0:
<script>
require(['elgg', 'jquery'], function (elgg, $) {
$(function () {
// code using $ and elgg
});
});
</script>
Attribute formatter removes keys with underscores¶
elgg_format_attributes()
(and all APIs that use it) now filter out attributes whose name contains an
underscore. If the attribute begins with data-
, however, it will not be removed.
Breadcrumbs¶
Breadcrumb display now removes the last item if it does not contain a link. To restore the previous behavior,
replace the plugin hook handler elgg_prepare_breadcrumbs
with your own:
elgg_unregister_plugin_hook_handler('prepare', 'breadcrumbs', 'elgg_prepare_breadcrumbs');
elgg_register_plugin_hook_handler('prepare', 'breadcrumbs', 'myplugin_prepare_breadcrumbs');
function myplugin_prepare_breadcrumbs($hook, $type, $breadcrumbs, $params) {
// just apply excerpt to titles
foreach (array_keys($breadcrumbs) as $i) {
$breadcrumbs[$i]['title'] = elgg_get_excerpt($breadcrumbs[$i]['title'], 100);
}
return $breadcrumbs;
}
Callbacks in Queries¶
Make sure to use only valid callable values for «callback» argument/options in the API.
Querying functions will now will throw a RuntimeException
if is_callable()
returns false
for the given
callback value. This includes functions such as elgg_get_entities()
, get_data()
, and many more.
Comments plugin hook¶
Plugins can now return an empty string from 'comments',$entity_type
hook in order to override the default comments component view. To force the default comments component, your plugin must return false
. If you were using empty strings to force the default comments view, you need to update your hook handlers to return false
.
Container permissions hook¶
The behavior of the container_permissions_check
hook has changed when an entity is being created: Before 2.0, the hook would be called twice if the entity’s container was not the owner. On the first call, the entity’s owner would be passed in as $params['container']
, which could confuse handlers.
In 2.0, when an entity is created in a container like a group, if the owner is the same as the logged in user (almost always the case), this first check is bypassed. So the container_permissions_check
hook will almost always be called once with $params['container']
being the correct container of the entity.
Creating or deleting a relationship triggers only one event¶
The «create» and «delete» relationship events are now only fired once, with "relationship"
as the object type.
E.g. Listening for the "create", "member"
or "delete", "member"
event(s) will no longer capture group membership additions/removals. Use the "create", "relationship"
or "delete", "relationship"
events.
Discussion feature has been pulled from groups into its own plugin¶
The object, groupforumtopic
subtype has been replaced with the
object, discussion
subtype. If your plugin is using or altering
the old discussion feature, you should upgrade it to use the new
subtype.
Nothing changes from the group owners” point of view. The discussion feature is still available as a group tool and all old discussions are intact.
Dropped login-over-https feature¶
For the best security and performance, serve all pages over HTTPS by switching
the scheme in your site’s wwwroot to https
at http://yoursite.tld/admin/settings/advanced
Elgg has migrated from ext/mysql to PDO MySQL¶
Elgg now uses a PDO_MYSQL
connection and no longer uses any ext/mysql functions. If you use
mysql_*
functions, implicitly relying on an open connection, these will fail.
If your code uses one of the following functions, read below.
execute_delayed_write_query()
execute_delayed_read_query()
If you provide a callable $handler
to be called with the results, your handler will now receive a
\Doctrine\DBAL\Driver\Statement
object. Formerly this was an ext/mysql result
resource.
Event/Hook calling order may change¶
When registering for events/hooks, the all
keyword for wildcard matching no longer has any effect
on the order that handlers are called. To ensure your handler is called last, you must give it the
highest priority of all matching handlers, or to ensure your handler is called first, you must give
it the lowest priority of all matching handlers.
If handlers were registered with the same priority, these are called in the order they were registered.
To emulate prior behavior, Elgg core handlers registered with the all
keyword have been raised in
priority. Some of these handlers will most likely be called in a different order.
export/
URLs are no longer available¶
Elgg no longer provides this endpoint for exposing resource data.
Icons migrated to Font Awesome¶
Elgg’s sprites and most of the CSS classes beginning with elgg-icon-
have been removed.
Usage of elgg_view_icon()
is backward compatible, but static HTML using the elgg-icon
classes will have to be updated to the new markup.
input/autocomplete view¶
Plugins that override the input/autocomplete
view will need to include the source URL in the data-source
attribute of the input element, require the new elgg/autocomplete
AMD module, and call its init
method. The 1.x javascript library elgg.autocomplete
is no longer used.
Introduced third-party library for sending email¶
We are using the excellent Zend\Mail
library to send emails in Elgg 2.0.
There are likely edge cases that the library handles differently than Elgg 1.x.
Take care to test your email notifications carefully when upgrading to 2.0.
Label elements¶
The following views received label
elements around some of the input fields. If your plugin/theme overrides these views please check for the new content.
- views/default/core/river/filter.php
- views/default/forms/admin/plugins/filter.php
- views/default/forms/admin/plugins/sort.php
- views/default/forms/login.php
Plugin Aalborg Theme¶
The view page/elements/navbar
now uses a Font Awesome icon for the mobile menu selector instead of an image. The bars.png
image and supporting CSS for the 1.12 rendering has been removed, so update your theme accordingly.
Plugin Likes¶
Objects are no longer likable by default. To support liking, you can register a handler to permit the annotation,
or more simply register for the hook ["likes:is_likable", "<type>:<subtype>"]
and return true. E.g.
elgg_register_plugin_hook_handler('likes:is_likable', 'object:mysubtype', 'Elgg\Values::getTrue');
Just as before, the permissions_check:annotate
hook is still called and may be used to override default behavior.
Plugin Messages¶
If you’ve removed or replaced the handler function messages_notifier
to hide/alter the inbox icon, you’ll instead need to do the
same for the topbar menu handler messages_register_topbar
. messages_notifier
is no longer used to add the menu link.
Messages will no longer get the metadata “msg” for newly created messages. This means you can not rely on that metadata to exist.
Plugin Blog¶
The blog pages showing “Mine” or “Friends” listings of blogs have been changed to list all the blogs owned by the users (including those created in groups).
Plugin Bookmarks¶
The bookmark pages showing “Mine” or “Friends” listings of bookmarks have been changed to list all the bookmarks owned by the users (including those created in groups).
Plugin File¶
The file pages showing “Mine” or “Friends” listings of files have been changed to list all the files owned by the users (including those created in groups).

- 7:$pagination
Removed Plugin Hooks¶
[display, view]
: See the new plugin hook.
Removed Actions¶
widgets/upgrade
Removed Views¶
forms/admin/plugins/change_state
Removed View Variables¶
During rendering, the view system no longer injects these into the scope:
$vars['url']
: replace withelgg_get_site_url()
$vars['user']
: replace withelgg_get_logged_in_user_entity()
$vars['config']
: useelgg_get_config()
andelgg_set_config()
$CONFIG
: useelgg_get_config()
andelgg_set_config()
Also several workarounds for very old views are no longer performed. Make these changes:
- Set
$vars['full_view']
instead of$vars['full']
.- Set
$vars['name']
instead of$vars['internalname']
.- Set
$vars['id']
instead of$vars['internalid']
.
Removed libraries¶
elgg:markdown
: Elgg no longer provides a markdown implementation. You must provide your own.
Specifying View via Properties¶
The metadata $entity->view
no longer specifies the view used to render in elgg_view_entity()
.
Similarly the property $annotation->view
no longer has an effect within elgg_view_annotation()
.
Viewtype is static after the initial elgg_get_viewtype()
call¶
elgg_set_viewtype()
must be used to set the viewtype at runtime. Although Elgg still checks the
view
input and $CONFIG->view
initially, this is only done once per request.
Deprecations¶
It’s deprecated to read or write to metadata keys starting with filestore::
on ElggFile
objects. In Elgg 3.0 this metadata will be deleted if it points to the current data root path, so few file objects will have it. Plugins should only use ElggFile::setFilestore
if files need to be stored in a custom location.
Nota
This is not the only deprecation in Elgg 2.0. Plugin developers should watch their site error logs.
From 1.10 to 1.11¶
Comment highlighting¶
If your theme is using the file views/default/css/elements/components.php
, you must add the following style definitions in it to enable highlighting for comments and discussion replies:
.elgg-comments .elgg-state-highlight {
-webkit-animation: comment-highlight 5s;
animation: comment-highlight 5s;
}
@-webkit-keyframes comment-highlight {
from {background: #dff2ff;}
to {background: white;}
}
@keyframes comment-highlight {
from {background: #dff2ff;}
to {background: white;}
}
From 1.9 to 1.10¶
File uploads¶
If your plugin is using a snippet copied from the file/upload
action to fix detected mime types for Microsoft zipped formats, it can now be safely removed.
If your upload action performs other manipulations on detected mime and simple types, it is recommended to make use of available plugin hooks:
'mime_type','file'
for filtering detected mime types'simple_type','file'
for filtering parsed simple types
De la versión 1.8 a la 1.9¶
En los ejemplos estamos actualizando un complemento imaginario, «Photos» (fotos).
Sólo se incluyen los cambios fundamentales. Por ejemplo, algunas de las funciones que están ahora obsoletas no se mencionan en esta sección.
Cada sección incluirá información sobre si el cambio es compatible hacia atrás con la versión 1.8 de Elgg.
El fichero «manifest»¶
Si su complemento es compatible con la versión 1.8 de Elgg, no necesita hacer ningún cambio en este fichero.
De todas formas, se recomienda añadir la etiqueta <id>
. Su valor debería ser el nombre de la carpeta que contiene el complemento dentro de la carpeta mod/
.
Si hace cambios que hacen el complemento incompatible con versiones anteriores con las que antes sí era compatible, debe actualizar la versión del complemento y la versión requerida de Elgg.
Ejemplo (resumido) de la versión anterior:
<?xml version="1.0" encoding="UTF-8"?>
<plugin_manifest xmlns="http://www.elgg.org/plugin_manifest/1.8">
<name>Photos</name>
<author>John Doe</author>
<version>1.0</version>
<description>Adds possibility to upload photos and arrange them into albums.</description>
<requires>
<type>elgg_release</type>
<version>1.8</version>
</requires>
</plugin_manifest>
Ejemplo (resumido) de la nueva versión:
<?xml version="1.0" encoding="UTF-8"?>
<plugin_manifest xmlns="http://www.elgg.org/plugin_manifest/1.8">
<name>Photos</name>
<id>photos</id>
<author>John Doe</author>
<version>2.0</version>
<description>Adds possibility to upload photos and arrange them into albums.</description>
<requires>
<type>elgg_release</type>
<version>1.9</version>
</requires>
</plugin_manifest>
$CONFIG y $vars[“config”]¶
Tanto la variable global $CONFIG
como el parámetro $vars['config']
están obsoletos. Deberían substituirse por la función elgg_get_config()
.
Ejemplo de código de la versión anterior:
// Using the global $CONFIG variable:
global $CONFIG;
$plugins_path = $CONFIG->plugins_path
// Using the $vars view parameter:
$plugins_path = $vars['plugins_path'];
Ejemplo de código de la nueva versión:
$plugins_path = elgg_get_config('plugins_path');
Nota
Compatible con la versión 1.8.
Nota
Así se actualizó el complemento «community_plugins»: https://github.com/Elgg/community_plugins/commit/f233999bbd1478a200ee783679c2e2897c9a0483
Ficheros de idioma¶
En la versión 1.8 de Elgg, los ficheros de idioma necesitaban usar la función add_translation()
. A partir de la versión 1.9, basta con devolver el vector que previamente se pasó a la función como parámetro. El núcleo de Elgg se basará en el nombre del fichero (por ejemplo: «es.php») para determinar qué idioma contiene el fichero.
Ejemplo del método anterior en languages/en.php
:
$english = array(
'photos:all' => 'All photos',
);
add_translation('en', $english);
Ejemplo del nuevo método:
return array(
'photos:all' => 'All photos',
);
Advertencia
No es compatible con la versión 1.8.
Notificaciones¶
Uno de los cambios más importantes en la versión 1.9 de Elgg es el del sistema de notificaciones. El nuevo sistema de notificaciones ofrece formas más flexibles y escalables de enviar notificaciones.
Ejemplo del método anterior:
function photos_init() {
// Tell core that we want to send notifications about new photos
register_notification_object('object', 'photo', elgg_echo('photo:new'));
// Register a handler that creates the notification message
elgg_register_plugin_hook_handler('notify:entity:message', 'object', 'photos_notify_message');
}
/**
* Set the notification message body
*
* @param string $hook Hook name
* @param string $type Hook type
* @param string $message The current message body
* @param array $params Parameters about the photo
* @return string
*/
function photos_notify_message($hook, $type, $message, $params) {
$entity = $params['entity'];
$to_entity = $params['to_entity'];
$method = $params['method'];
if (elgg_instanceof($entity, 'object', 'photo')) {
$descr = $entity->excerpt;
$title = $entity->title;
$owner = $entity->getOwnerEntity();
return elgg_echo('photos:notification', array(
$owner->name,
$title,
$descr,
$entity->getURL()
));
}
return null;
}
Ejemplo del nuevo método:
function photos_init() {
elgg_register_notification_event('object', 'photo', array('create'));
elgg_register_plugin_hook_handler('prepare', 'notification:publish:object:photo', 'photos_prepare_notification');
}
/**
* Prepare a notification message about a new photo
*
* @param string $hook Hook name
* @param string $type Hook type
* @param Elgg_Notifications_Notification $notification The notification to prepare
* @param array $params Hook parameters
* @return Elgg_Notifications_Notification
*/
function photos_prepare_notification($hook, $type, $notification, $params) {
$entity = $params['event']->getObject();
$owner = $params['event']->getActor();
$recipient = $params['recipient'];
$language = $params['language'];
$method = $params['method'];
// Title for the notification
$notification->subject = elgg_echo('photos:notify:subject', array($entity->title), $language);
// Message body for the notification
$notification->body = elgg_echo('photos:notify:body', array(
$owner->name,
$entity->title,
$entity->getExcerpt(),
$entity->getURL()
), $language);
// The summary text is used e.g. by the site_notifications plugin
$notification->summary = elgg_echo('photos:notify:summary', array($entity->title), $language);
return $notification;
}
Advertencia
No es compatible con la versión 1.8.
Nota
Así se actualizó el complemento «community_plugins» para usar el nuevo sistema: https://github.com/Elgg/community_plugins/commit/bfa356cfe8fb99ebbca4109a1b8a1383b70ff123
Notifications can also be sent with the notify_user()
function.
It has however been updated to support three new optional parameters passed inside an array as the fifth parameter.
The parameters give notification plugins more control over the notifications, so they should be included whenever possible. For example the bundled site_notifications plugin won’t work properly if the parameters are missing.
Parameters:
- object The object that we are notifying about (e.g. ElggEntity or ElggAnnotation). This is needed so that notification plugins can provide a link to the object.
- action String that describes the action that triggered the notification (e.g. «create», «update», etc).
- summary String that contains a summary of the notification. (It should be more informative than the notification subject but less informative than the notification body.)
Ejemplo del método anterior:
// Notify $owner that $user has added a $rating to an $entity created by him
$subject = elgg_echo('rating:notify:subject');
$body = elgg_echo('rating:notify:body', array(
$owner->name,
$user->name,
$entity->title,
$entity->getURL(),
));
notify_user($owner->guid,
$user->guid,
$subject,
$body
);
Ejemplo del nuevo método:
// Notify $owner that $user has added a $rating to an $entity created by him
$subject = elgg_echo('rating:notify:subject');
$summary = elgg_echo('rating:notify:summary', array($entity->title));
$body = elgg_echo('rating:notify:body', array(
$owner->name,
$user->name,
$entity->title,
$entity->getURL(),
));
$params = array(
'object' => $rating,
'action' => 'create',
'summary' => $summary,
);
notify_user($owner->guid,
$user->guid,
$subject,
$body,
$params
);
Nota
Compatible con la versión 1.8.
Añadir elementos a la lista de actividad¶
add_to_river('river/object/photo/create', 'create', $user_guid, $photo_guid);
elgg_create_river_item(array(
'view' => 'river/object/photo/create',
'action_type' => 'create',
'subject_guid' => $user_guid,
'object_guid' => $photo_guid,
));
También puede hacer uso del parámetro opcional target_guid
para indicar el destinatario de la acción de crear.
Por ejemplo, si la foto se pretendiese añadir a un álbum de fotos, se haría pasándole también:
'target_guid' => $album_guid,
Advertencia
No es compatible con la versión 1.8.
Gestores de direcciones URL de entidades¶
La función elgg_register_entity_url_handler()
ha pasado a estar obsoleta en la versión 1.9 de Elgg, donde se recomienda usar el gancho de complementos 'entity:url', 'object'
en us lugar.
Ejemplo del método anterior:
/**
* Initialize the photo plugin
*/
my_plugin_init() {
elgg_register_entity_url_handler('object', 'photo', 'photo_url_handler');
}
/**
* Returns the URL from a photo entity
*
* @param ElggEntity $entity
* @return string
*/
function photo_url_handler($entity) {
return "photo/view/{$entity->guid}";
}
Ejemplo del nuevo método:
/**
* Initialize the photo plugin
*/
my_plugin_init() {
elgg_register_plugin_hook_handler('entity:url', 'object', 'photo_url_handler');
}
/**
* Returns the URL from a photo entity
*
* @param string $hook 'entity:url'
* @param string $type 'object'
* @param string $url The current URL
* @param array $params Hook parameters
* @return string
*/
function photo_url_handler($hook, $type, $url, $params) {
$entity = $params['entity'];
// Check that the entity is a photo object
if ($entity->getSubtype() !== 'photo') {
// This is not a photo object, so there's no need to go further
return;
}
return "photo/view/{$entity->guid}";
}
Advertencia
No es compatible con la versión 1.8.
Servicios web¶
In Elgg 1.8 the web services API was included in core and methods were exposed
using expose_function()
. To enable the same functionality for Elgg 1.9,
enable the «Web services 1.9» plugin and replace all calls to
expose_function()
with elgg_ws_expose_function()
.
De la versión 1.7 a la 1.8¶
La versión 1.8 ha sido el mayor salto en el desarrollo de Elgg desde la versión 1.0. Es por ello que para actualizar el núcleo de Elgg y sus complementos hace falta más trabajo que en anteriores actualizaciones. Se produjeron algunos cambios pequeños en la API, y siguiendo con nuestra práctica habitual, los métodos que pasaron a quedar obsoletos se actualizaron para funcionar con la nueva API. Los cambios más importantes afectaron a la estandarización de complementos y al sistema de vistas.
Actualizar el núcleo¶
Elimine las siguientes carpetas (se encuentran en el mismo nivel que «_graphics» o «engine»):
- _css
- account
- admin
- dashboard
- entities
- friends
- search
- settings
- simplecache
- views
Advertencia
Tendrá problemas si no elimina estas carpetas antes de actualizar.
Actualizar complementos¶
Use encaminamientos estándar con gestores de páginas¶
- Todo: /page_handler/all
- Contenido del usuario: /page_handler/owner/:username
- Contenido de contactos del usuario: /page_handler/friends/:username
- Entidad suelta: /page_handler/view/:guid/:title
- Añadido: /page_handler/add/:container_guid
- Edición: /page_handler/edit/:guid
- Lista de grupos: /page_handler/group/:guid/all
Incluya scripts de gestión de páginas desde el gestor de páginas¶
Casi todos los gestores de páginas deberían tener un script de gestión de páginas. Por ejemplo, bookmarks/all => mod/bookmarks/pages/bookmarks/all.php
.
- Llame a
set_input()
para identificadores de entidades en el gestor de páginas y useget_input()
en los scripts de gestión de páginas. - Llame a
gatekeeper()
y aadmin_gatekeeper()
en la función del gestor de páginas si fuese necesario. - La dirección URL del grupo debería usar el script
pages/:handler/owner.php
. - Los gestores de páginas no deberían contener HTML.
- Actualice las direcciones URL en todo el complemento. No se olvide de eliminar
/pg/
.
Use gestores de páginas y scripts estandarizados¶
Guarde los scripts de gestión de páginas en
mod/:plugin/pages/:page_handler/:page_name.php
Use la disposición de página del contenido en los scripts de gestión de páginas:
$content = elgg_view_layout('content', $options);
Los scripts de gestión de páginas no deberían contener HTML.
Llame a
elgg_push_breadcrumb()
en los scripts de gestión de páginas.No es necesario definir el dueño de una página si las direcciones URL están en el formato estándar.
Para el contenido de grupos, compruebe el identificador del contenedor (
container_guid
) mediante la funciónelgg_get_page_owner_entity()
.
La vista object/:subtype
¶
- Asegúrese de que hay vistas para
$vars['full_view'] == true
y$vars['full_view'] == false
.$vars['full_view']
ha substituido a$vars['full]
. - Compruebe el objeto en
$vars['entity']
. Useelgg_instance_of()
para asegurarse de que se trata de el tipo de entidad que busca. - Devuelva
true
para cancelar la vista directamente si falta la entidad o ésta no es correcta. - Use
elgg_view(‘object/elements/summary’, array(‘entity’ => $entity));
yelgg_view_menu(‘entity’, array(‘entity’ => $entity));
como ayuda para dar formato. Debería usar poco o ningún lenguaje de etiquetas en estas vistas.
Actualizar la estructura de las acciones¶
- Use espacios de nombre para ficheros y nombres de acciones. Por ejemplo,
mod/blog/actions/blog/save.php
→action/blog/save
. - Use las siguientes direcciones URL de acciones:
- Añadir:
action/:plugin/save
. - Editar:
action/:plugin/save
. - Eliminar:
action/:plugin/delete
.
- Añadir:
- Haga que la acción de eliminar acepte
action/:handler/delete?guid=:guid
de forma que el menú de entidades de metadatos tenga la dirección URL correcta de manera predeterminada.
Actualice las funciones que se hayan quedado obsoletas¶
- Las funciones marcadas como obsoletas en la versión 1.7 de Elgg producen errores visibles en la versión 1.8.
- También puede actualizar funciones que se marcaron como obsoletas en la versión 1.8.
- A muchas funciones de registro simplemente se les añadió el prefijo
elgg_
por motivos de consistencia, y actualizarlas no debería ser difícil. - Véase la lista completa en
/engine/lib/deprecated-1.8.php
. - Puede cambiar el nivel de depuración a «warning» (aviso) para recibir de manera visual recordatorios sobre el uso de funciones obsoletas.
- A muchas funciones de registro simplemente se les añadió el prefijo
Actualice las vistas de artilugios¶
Puede tomar como ejemplos los artilugios de blogs o de ficheros.
Actualice el módulo de perfiles de grupos¶
Use los complementos de blogs y de ficheros a modo de ejemplo. Le ayudarán a hacer posible cambiar el tema del complemento usando la nueva infraestructura CSS.
Actualice los formularios¶
- Mueva los cuerpos de los formularios a la vista
forms/:action
para usar el nuevoelgg_view_form
de Evan. - Use las vistas de introducción de datos en los cuerpos de los formularios en vez de usar HTML. Esto ayudará a que el complemento sea compatible con los temas, y a que sea más fácil de mantener ante cambios futuros.
- Añada una función que prepare el formulario. A modo de ejemplo, véase
mod/file/lib/file.php
. - Persista los formularios. A modo de ejemplo, véanse la acción de enviar (upload) del complemento de ficheros y su función para preparar el formulario.
La API de los formularios se describe con más detalle en Formularios y acciones.
Haz limpieza de CSS y HTML¶
Se han añadido muchos patrones de CSS al fichero CSS base (módulos, bloques de imágenes, primitivas de espaciado). Se recomienda usar dichos patrones y clases siempre que sea posible. De esa forma:
- Se reducen los costes de mantenimiento, puesto que puede eliminar la mayor parte de su código CSS personalizado.
- Su complemento es más compatible con los temas de la comunidad.
Si necesita mucho código CSS, busque patrones que podrían añadirse al núcleo de Elgg.
Usamos guiones en vez de guiones bajos en las clases e identificadores, y le recomendamos que haga lo mismo por consistencia.
Si de verdad necesita su propio CSS, debería usar si propio espacio de nombres, uno distinto de elgg-
.
Actualice el fichero manifest.xml¶
- Use http://el.gg/manifest17to18 para automatizar la tarea.
- No utilice la categoría «bundled» (de serie) en sus complementos. Esa categoría corresponde sólo a complementos distribuidos junto con Elgg.
Actualice las vistas de configuración global y de usuario¶
- La vista de configuración ha pasado a ser
plugins/:plugin/settings
(antes erasettings/:plugin/edit
). - La vista de configuración de usuario ha pasado a ser
plugins/:plugin/usersettings
(antes erausersettings/:plugin/edit
).
