Child Theme: override the variables
I'm going to build my first Classipress Child. I understood how to override functions (hope!), but how to override variables?
For example, I want to change the values of feed variables shown in functions.php:
PHP Code:
$app_rss_feed = 'http://feeds2.feedburner.com/appthemes';
$app_twitter_rss_feed = 'http://twitter.com/statuses/user_timeline/appthemes.rss';
$app_forum_rss_feed = 'http://www.appthemes.com/forum/external.php?type=RSS2';
But if I create my functions.php file inside my child theme and assign a different RSS feed value to these variables... nothing happens.
So, which is the right way to change variables?
