I just had to do something similar - check if gallery is being used on a page and output a div if not.

I put this within

$page_data = get_page( $post->ID ); $content = $page_data->post_content; $pos = strpos($content, '[gallery]' ); if( $pos === false ) { $found = false; } else { $found = true; }

Then you can do your conditionals..

So were do I put those codes exactly? I'm looking for ways to minimize the pageload on my home page and this gallery plugin is the first thing that needs to go. Thing is I'm not really a coding guru, I would like to have a file and location where to put it and I'll be okay

Thanks in advance.

Found one trivial little fix. This fails if the shortcode is the first thing in the post content. stripos would return 0 so the if wouldn't fire. Changing it to !== false fixed it.

Admittedly a pretty unlikely deal, but I'm working on a plugin and the test post had the shortcode as the only content.

Trying to get this technique to work with the Audio-player plugin( http://wordpress.org/extend/plugins/audio-player/ ).

It uses addHeaderCode() and addFooterCode() too insert.

Could you point me in the right direction please?

@Ted: yes, correctly and how you load your css, always or only when you add the shortcode in the content?

@Justin: thanks for your reply and your hint to this small code tipps. Yes, you have right, this works only when use the shortcode on post content: On my own solutions i add a metabox to the editor with a radiobutton or checkbox to add js or css for custom solutions.

I put this code in function.php

function remove_gallery_css() { return ""; } add_filter('gallery_style', 'remove_gallery_css');

so I can style my gallery in my stylesheet

This only works in the case of the shortcode being in the post content. It doesn't take into account that users may put the gallery in other places on their page (other shortcode-ready areas). I've seen a few posts on checking the post content before loading JavaScript and CSS lately. All of them make the assumption that users only add stuff to their post content. But, the solution I like the most is to simply add the gallery styles to the theme's style.css file. I also like just making one JavaScript file (jQuery, usually), and only having to load it. Also, for anyone using child themes, you need to replace get_bloginfo('template_directory') with get_stylesheet_directory_uri() for this tutorial. This also works when not using a child theme.
