I'm running the Options theme (Spartan child theme) on Wordpress 2.7. I'm trying to get the stumble it button into my single.php page. There's a hook already in there - op_after_single, so I figure it's better to use that and then any theme upgrades won't break it, (plus I figure I'm going to have to learn sooner or later), but I'm absolutely new to hooks, and need help... The stumble upon code is: <a href="http://www.stumbleupon.com/submit?url=%26title%3DThe%2BArticle%2BTitle"> <img border=0 src="http://cdn.stumble-upon.com/images/120x20_su_blue.gif" alt=""> Stumble It!</a> HTML: The hook in single.php is: <?php op_after_single(); // Single post hook ?> PHP: What do I have to do, (in idiot-proof language please) to get that hook to execute that html code? Help? Please? PS links to any plain language tutorials to help me understand hooks would also be appreciated.
