Member Function Documentation

◆ do_context_membership_request()

enrol_lti\task\sync_members::do_context_membership_request	(	Context	$context,
		ResourceLink	$resourcelink = `null`,
			$membershipsurltemplate = `''`
	)

protected

Performs membership service request using an LTI Context object.

If the context has a 'custom_context_memberships_url' setting, we use this to perform the membership service request. Otherwise, if a context is associated with resource link, we try first to get the members using the ResourceLink::doMembershipsService() method. If we're still unable to fetch members from the resource link, we try to build a memberships URL from the memberships URL endpoint template that is defined in the ToolConsumer profile and substitute the parameters accordingly.

Parameters

Context	$context	The context object.
ResourceLink	$resourcelink	The resource link object.
string	$membershipsurltemplate	The memberships endpoint URL template.

Return values

bool|User[] Array of User objects upon successful membership service request. False, otherwise.

◆ do_resourcelink_membership_request()
