Detailed Description

The global navigation class used especially for AJAX requests.

The primary methods that are used in the global navigation class have been overriden to ensure that only the relevant branch is generated at the root of the tree. This can be done because AJAX is only used when the backwards structure for the requested branch exists. This has been done only because it shortens the amounts of information that is generated which of course will speed up the response time.. because no one likes laggy AJAX.

Return values
bool

◆ can_expand_course()

global_navigation::can_expand_course ( $course)
protectedinherited

Checks if a user can expand a course in the navigation.

We use a cache here because in order to be accurate we need to call can_access_course which is a costly function. Because this functionality is basic + non-essential and because we lack good event triggering this cache permits stale data. In the situation the user is granted access to a course after we've initialised this session cache the cache will be stale. It is brought up to date in only one of two ways.

  1. The user logs out and in again.
  2. The user browses to the course they've just being given access to.

Really all this controls is whether the node is shown as expandable or not. It is uber un-important.

Parameters
stdClass$course
Return values
bool

◆ check_if_active()

Return values
bool

◆ contains_active_node()

pix_icon$icon
Return values
navigation_node

protectedinherited

Returns true if the current user is a parent of the user being currently viewed.

If the current user is not viewing another user, or if the current user does not hold any parent roles over the other user being viewed this function returns false. In order to set the user for whom we are checking against you must call set_userid_for_parent_checks()

global_navigation::extend_for_user ( $user)
inherited

Extends the navigation for the given user.

If you know that the node being searched for is a child of this node then use the global_navigation::get() method instead.

Note: If you are trying to set the active node navigation_node::override_active_url() may be of more use to you.

?int$typeOne of navigation_node\TYPE_*
Return values
navigation_node|false

Reimplemented from navigation_node.
