Used to display a rotating ad drawn randomly from the database (banners or text ads).

This action has one variable:
• Category: the ad category for ads you want to display. You can also use "%" as a 'wild card' to show all ads.

Examples:

<?php action('show_rotating_ad','search'); ?>

would show an ad drawn in the search ad group.

<?php action('show_rotating_ad','%'); ?>

would show an ad drawn from all ads in the database.
