Page ownership

One recurring task of any plugin will be to determine the page ownership in order to decide which actions are allowed or not. Elgg has a number of functions related to page ownership and also offers plugin developers flexibility by letting the plugin handle page ownership requests as well. Determining the owner of a page can be determined with elgg_get_page_owner_guid(), which will return the GUID of the owner. Alternatively, elgg_get_page_owner_entity() will retrieve the whole page owner entity. If the page already knows who the page owner is, but the system doesn’t, the page can set the page owner by passing the GUID to elgg_set_page_owner_guid($guid).

Note

The page owner entity can be any ElggEntity. If you wish to only apply some setting in case of a user or a group make sure you check that you have the correct entity.

Page owner detection

Based on the route definition:

• If the name starts with view or edit the parameters username and guid are checked

• If the name starts with add or collection the parameters username, guid and container_guid are checked

• If in the route definition the value detect_page_owner is set to true the parameters username, guid and container_guid are checked
