Detailed Description

Base class for theme backup plugins.

NOTE: When you back up a course, it runs backup for ALL themes - not just the currently selected one.

That means that if, for example, a course was once in theme A, and theme A had some data settings, but it is then changed to theme B, the data settings will still be included in the backup and restore. With the restored course, if you ever change it back to theme A, the settings will be ready.

It also means that other themes which are not the one set up for the course, but might be seen by some users (eg user themes, session themes, mnet themes) can store data.

If this behaviour is not desired for a particular theme's data, the subclass can call is_current_theme('myname') to check.

Member Function Documentation

get_theme_condition()

backup_theme_plugin::get_theme_condition ( )

protected

Return condition for whether this theme should be backed up (= if it is the same theme as the one used in this course).

This condition has the theme used in the course. It will be compared against the name of the theme, by use of third parameter in get_plugin_element; in subclass, you should do: $plugin = $this->get_plugin_element(null, $this->get_theme_condition(), 'mytheme');
