dirname() is a slow function compared with __DIR__ and using
'/../'. Moodle has a large number of legacy files that are included
each time a page loads and is not able to use an autoloader as it is
functional code. This allows those required includes to perform as
best as possible in this situation.
This reverts commit 6601690202764d786a5ee4b7bbd9afb5b91dd0ec.
This commit was adding the 'returnurl' param unnecessarily to the
course links in the navigation block, causing a lot of long URLs
to be created.
This patch improves usability of enrolment page in case of course is not
enrollable. 'Continue' button now returns student to referring page instead of
main moodle page (as it used to be). To make this improvement, passing correct
returnurl parameter to enrol/index.php page was implemented for links that may
be accessible for not-enrolled students.
Navigation has now been re-ordered in accordance with http://docs.moodle.org/en/Development:Navigation_2.0_structure.
This has led to several changes in the way in which navigation is generated included API changes, most notably using the
navigation_nodes add method now returns the newly added node rather than the key.
At the same time the global_navigation_tree block has been renamed to navigation and settings_navigation_tree to settings.
* AJAX expansion now uses JSON rather than XML
* Tidied up unused globals in navigaitonlib after recent refactoring
* Cleaned up Database calls that were no longer required after security changes
This patch introduces two new blocks global_navigation_tree and settings_navigation_tree
both of which have been designed to make full use of the new navigation objects available through
the $PAGE object.
Bulk of this code is within lib/navigationlib.php
