Return values

bool

◆ can_expand_course()

global_navigation::can_expand_course ( $course )

protected

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.

The user logs out and in again.
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()

navigation_node::check_if_active ( $strength = URL_MATCH_EXACT )

inherited

Checks if this node is the active node.

This is determined by comparing the action for the node against the defined URL for the page. A match will see this node marked as active.

Parameters

int $strength One of URL_MATCH_EXACT, URL_MATCH_PARAMS, or URL_MATCH_BASE

Return values

bool

◆ contains_active_node()

navigation_node::contains_active_node ( )

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.

If you need to search recursivily then use the global_navigation::find() method.

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

			$cm = `null`
	)

protected

Loads all of the courses section into the navigation.

This function calls method from current course format, see format_base::extend_course_navigation() If course module ($cm) is specified but course format failed to create the node, the activity node is created anyway.

By default course formats call the method global_navigation::load_generic_course_sections()

Parameters

stdClass	$course	Database record for the course
navigation_node	$coursenode	The course node within the navigation
null \| int	$sectionnum	If specified load the contents of section with this relative number
null \| cm_info	$cm	If specified make sure that activity node is created (either in containg section or by calling load_stealth_activity() )

		$forceforcontext = `false`
	)

Loads user specific information into the navigation in the appropriate place.

◆ make_active()

navigation_node::make_active ( )

inherited

Marks this node as active and forces it open.

Important: If you are here because you need to mark a node active to get the navigation to do what you want have you looked at navigation_node::override_active_url()? You can use it to specify a different URL to match the active navigation node on rather than having to locate and manually mark a node active.

◆ module_extends_navigation()

static global_navigation::module_extends_navigation ( $modname )

This method simply checks to see if a given module can extend the navigation.

Todo:: (MDL-25290) A shared caching solution should be used to save details on what extends navigation.

static navigation_node::override_active_url	(	moodle_url	$url,
			$loadadmintree = `false`
	)

staticinherited

The active node is the node that matches the URL set here. By default this is either $PAGE->url or if that hasn't been set $FULLME.

moodle_url	$url	The url to use for the fullmeurl.
bool	$loadadmintree	use true if the URL point to administration tree

◆ set_expansion_limit()

global_navigation::set_expansion_limit ( $type )
