Detailed Description

Functions and classes used during installation, upgrades and for admin settings.

ADMIN SETTINGS TREE INTRODUCTION

This file performs the following tasks: -it defines the necessary objects and interfaces to build the Moodle admin hierarchy -it defines the admin_externalpage_setup()

ADMIN_SETTING OBJECTS

Moodle settings are represented by objects that inherit from the admin_setting class. These objects encapsulate how to read a setting, how to write a new value to a setting, and how to appropriately display the HTML to modify the setting.

ADMIN_SETTINGPAGE OBJECTS

The admin_setting objects are then grouped into admin_settingpages. The latter appear in the Moodle admin tree block. All interaction with admin_settingpage objects is handled by the admin/settings.php file.

ADMIN_EXTERNALPAGE OBJECTS

There are some settings in Moodle that are too complex to (efficiently) handle with admin_settingpages. (Consider, for example, user management and displaying lists of users.) In this case, we use the admin_externalpage object. This object places a link to an external PHP file in the admin tree block.

If you're using an admin_externalpage object for some settings, you can take advantage of the admin_externalpage_* functions. For example, suppose you wanted to add a foo.php file into admin. First off, you add the following line to admin/settings/first.php (at the end of the file) or to some other file in admin/settings: $ADMIN->add('userinterface', new admin_externalpage('foo', get_string('foo'), $CFG->wwwdir . '/' . '$CFG->admin . '/foo.php', 'some_role_permission'));

Next, in foo.php, your file structure would resemble the following: require(DIR.'/../../config.php'); require_once($CFG->libdir.'/adminlib.php'); admin_externalpage_setup('foo'); // functionality like processing form submissions goes here echo $OUTPUT->header(); // your HTML goes here echo $OUTPUT->footer();

The admin_externalpage_setup() function call ensures the user is logged in, and makes sure that they have the proper role permission to access the page. It also configures all $PAGE properties needed for navigation.

ADMIN_CATEGORY OBJECTS

Above and beyond all this, we have admin_category objects. These objects appear as folders in the admin tree block. They contain admin_settingpage's, admin_externalpage's, and other admin_category's.

OTHER NOTES

admin_settingpage's, admin_externalpage's, and admin_category's all inherit from part_of_admin_tree (a pseudointerface). This interface insists that a class has a check_access method for access permissions, a locate method used to find a specific node in the admin tree and find parent path.

admin_category's inherit from parentable_part_of_admin_tree. This pseudo- interface ensures that the class implements a recursive add function which accepts a part_of_admin_tree object and searches for the proper place to put it. parentable_part_of_admin_tree implies part_of_admin_tree.

Please note that the $this->name field of any part_of_admin_tree must be UNIQUE throughout the ENTIRE admin tree.

The $this->name field of an admin_setting object (which is not part_of_ admin_tree) must be unique on the respective admin_settingpage where it is used.
