Returns regular expression used to search for shortcodes inside posts.
This function combines all registered shortcode tags into a single regular expression.
<?php
function your_prefix_detect_shortcode()
{
global $post;
$pattern = get_shortcode_regex();
preg_match_all( '/'. $pattern .'/s', $post->post_content, $matches );
if( is_array( $matches ) && array_key_exists( 2, $matches ) && in_array( 'your-shortcode', $matches[2] ) )
{
// shortcode is being used
}
}
add_action( 'wp', 'your_prefix_detect_shortcode' );
?>
This can only be used when $post is available, of course. 'wp' is the earliest action you can hook into to get access to it.
Note: The example that previously appeared on this page used preg_match() instead of preg_match_all(), so it only detected the first shortcode used on the page. You should update any code that uses that example with the current example in order to fix that bug.
None
