Theme location
In the standard Moodle distribution, all themes are placed in the theme/ directory of moodle, this leads to theme developers hardcoding this location into their themes. Theme developers should not take this for granted, and use the variables which moodle provides for this purpose.
Starting with 1.7, moodle will fully support changing the location of themes using the variables discussed below.
$CFG->themewww
The $CFG->themewww variable contains the web-accessible location of the theme directory. If it is not set by the site administrator it will be the default of $CFG->wwwroot . '/theme'. i.e. 'http://my.moodle.site/theme'.
$CFG->httpsthemewww
The $CFG->httpsthemewww' (introduced in Moodle 1.7) variable contains the same information as $CFG->themewww with the correct http/https prefix. This should be used to provide proper operation of https protected pages.
$CFG->themedir
The $CFG->themedir variable contains the local location on the moodle server of the theme directory. If it is not set by the site administrator it will be the default of $CFG->dirroot . '/theme'. i.e. '/my/moodle/location/theme'.
Changing theme Location
Starting from Moodle 1.7, the location of themes may be altered, using the variables $CFG->themewww and $CFG->themedir
If you wish to place themes in a subdirectory called 'my_moodle_themes', your config.php might look like this:
$CFG->wwwroot = 'http://my.moodle.site.edu'; $CFG->dirroot = '/var/www/my.moodle.site.edu/public_html'; $CFG->themewww = $CFG->wwwroot . '/my_moodle_themes'; $CFG->themedir = $CFG->dirroot . '/my_moodle_themes';
