To WordPress, as it parses through the content, only the tags using square brackets will be treated as short codes. The curly bracket example given would not be parsed by the WordPress core. It is possible the tag would be parsed by a plugin or theme if they are looking for hooks in the content … Read more
Don’t use output buffering. It is too slow and sometimes hard to debug. Use heredoc. Example: $output = <<<MYUNIQUENAME <div>$foo <p>Some $bar</p> </div> MYUNIQUENAME;
Add a static variable to the shortcode handler to check if the shortcode has been called already. Sample code add_shortcode( ‘wpse62826’, ‘wpse_62826_shortcode’ ); function wpse_62826_shortcode() { static $done = FALSE; // Nothing to do. if ( $done ) { return; } if ( is_singular() ) { $done = TRUE; } return ‘<b>I run once on … Read more
Use get_template_directory_uri() print get_template_directory_uri() . ‘/image.jpg’; In child themes use get_stylesheet_directory_uri() if you have replaced the image. In a shortcode this would look like this: <?php /* Plugin Name: Theme URI Shortcode */ add_shortcode(‘theme_uri’, ‘wpse_66026_theme_uri_shortcode’ ); function wpse_66026_theme_uri_shortcode( $attrs = array (), $content=”” ) { $theme_uri = is_child_theme() ? get_stylesheet_directory_uri() : get_template_directory_uri(); return trailingslashit( $theme_uri … Read more
Make sure that the string in $short variable is between square brakets, like [header]. If it’s not stored that way, make the call like this echo do_shortcode(‘[‘.$short.’]’);
There aren’t currently any shortcodes for venue information (address, postcode, other meta etc). However, you can copy the single-event.php template (find it in the templates directory of the plug-in) into your theme and edit it there to include venue information via provided template functions: Available functions When used inside the loop, you don’t need to … Read more
By chance I just happened to discover what it was, so I think I’ll leave this here as it might help someone in the future. Some web pages, including an answer to this question suggest using the following code to prevent wpautop from running until after the shortcodes. Now I wasn’t able to fully understand … Read more
No. echo do_shortcode() is a function call. You can not pass a conditional statement as an argument of a function. What you need to do is pass in the returned result of your query as an argument of the function; //assuming you have taken care of your query prior to this point if ( have_posts() … Read more
The correct way is calling remove_filter with the same priority as the hook was added: remove_filter( ‘the_content’, ‘do_shortcode’, 11 ); Some plugins change this filter’s priority, so you could clear the global list of registered shortcodes temporary: add_filter( ‘the_content’, ‘toggle_shortcodes’, -1 ); add_filter( ‘the_content’, ‘toggle_shortcodes’, PHP_INT_MAX ); function toggle_shortcodes( $content ) { static $original_shortcodes = … Read more
$page_id = get_queried_object_id(); $page_object = get_page( $page_id ); if ( strpos($page_object->post_content, ‘[/slider]’) )
