I’ve been trying to write a plugin that filter categories on the homepage.
Given a set of categories saved as options in the DB., I retrieve them like:
$categories = get_option(‘tecf_cat-list’);
Then I use:
$query = new WP_Query(array( ‘category__not_in’ => $categories ) );
but I get a blank page after using this.
I’m calling the function on the ‘posts_request’ hook.
Shouldn’t I use WP_Query() from within a plugin? (I tried to modify values of the global $wp_query variable without success).
Any clues about this incident? (You can point me to the right documentation, I’m not afraid to read).
