Short Answer Yes, shortcodes are case sensitive Longer Answer It’s really easy to build a test case for this and see. <?php add_shortcode(‘sOme_ShOrTcOdE’, ‘wpse102375_shortcode’); function wpse102375_shortcode($args, $content=null) { return ‘yep’; } Longest Answer Read the source. The “magic” with shortcodes happens in do_shortcode, so let’s take a look at that. <?php // wp-includes/shortcode.php function do_shortcode($content) … Read more
I think your problem is with the $output = include …. statement. include() returns true or false based whether it was successful – not the content of the file being included. Use output buffering to get the content. function service_shortcode_index() { global $content; ob_start(); include ( TEMPLATEPATH . ‘/service.php’ ); $output = ob_get_clean(); return $output; … Read more
From: http://codex.wordpress.org/Shortcode_API#Limitations The shortcode parser correctly deals with nested shortcode macros, provided their handler functions support it by recursively calling do_shortcode() It will not let you nest the same shortcode inside another though: However the parser will fail if a shortcode macro is used to enclose another macro of the same name Assuming you won’t … Read more
You can actually list all of the available shortcodes for your WordPress installation by using the following code: <?php global $shortcode_tags; echo ‘<pre>’; print_r($shortcode_tags); echo ‘</pre>’; ?> It will show the main WordPress shortcodes plus any shortcodes for installed plugins which can be handy too!

If it’s too much trouble converting all of your output statements, or you need to use a function that will always display the output, you can use output buffering. A buffer will ‘catch’ … Read more
Yes it is possible. There are two ways that I can think of at this moment. First follow what the codex says Shortcodes. Basically you just wrap your html in ob_start(); this will return the html as a string so you can echo it. function my_shortcode() { ob_start(); ?> <HTML> <here> … <?php return ob_get_clean(); … Read more
I removed all that duplicated and unnecessary stuff, take a look at otto’s or kaiser’s answers for the very simple solution. Trac ticket: #29629. Codex entry for Playlist Shortcode.
The WordPress enqueue system should prevent the inclusion of the same script multiple times, and does when I test it. For example, the following enqueues a Core script and echos a counter. If I put this shortcode into a post 4 times, I get “0123” but the media script only loads one time. The same … Read more
It’s probably best to render the shortcode on output by running it through do_shortcode()
