Footer.php Action Hook

One piece of code that should be included with your theme, but is not required, is the action hook, wp_footer().

Most theme developers, however, do include this hook in the footer.php file. Personally, this hook should be required for all themes. Since it is optional, you need to add it to your footer.php file if it does not already exist. The cd-ad-sponsor plug-in uses this hook to reset the database table of sponsor ads that have been displayed.

If you set the Clear Clickthrough Counts option on the Default Options page, then the clickthrough counts are cleared for each IP listed on the Manage Excluded IP page. This procedure is performed only after your page has completely been displayed.

Verify that the following code is toward the end of your footer.php file.

<?php wp_footer(); ?>

Note: This theme modification is necessary only if the wp_footer() hook does not currently exist. The default themes, twentyten and twentyeleven, contain the wp_footer() hook.
