Try this. Add the code below to your functions.php file – add_shortcode(‘cat_description’, ‘my_cat_description_shortcode’); function my_cat_description_shortcode($atts){ $a = shortcode_atts( array( ‘id’ => 0, ), $atts ); return category_description($a[‘id’]); } Should you wish to call the shortcode from a template (unnecessary really unless you add more to the shortcode) you can use this code – <?php echo … Read more
When you look at how do_shortcode() actually works, then it’s this: do_shortcode( $content ) Where $content is defined as the following: (string) Content to search for shortcodes What you are trying to do is to echo what the shortcode does, leading to a false assumption.

Here is the simplest shortcode that will do the job for you add_shortcode(‘USER_META’, ‘user_meta_shortcode_handler’); /** * User Meta Shortcode handler * usage: [USER_META user_id=1 meta=”first_name”] * @param array $atts * @param string $content * @return stirng */ function user_meta_shortcode_handler($atts,$content=null){ return esc_html(get_user_meta($atts[‘user_id’], $atts[‘meta’], true)); } USAGE: [USER_META user_id=1 meta=”first_name”] [USER_META user_id=1 meta=”last_name”]
To use a different callback for the nested headings switch the shortcode handler in the pricing_box callback and restore the main handler before you return the string. add_shortcode( ‘pricing_box’, ‘shortcode_pricing_box’ ); add_shortcode( ‘heading’, ‘shortcode_heading_main’ ); function shortcode_pricing_box( $atts, $content=”” ) { // switch shortcode handlers add_shortcode( ‘heading’, ‘shortcode_heading_pricing_box’ ); $out=”<div class=”pricing-box”>” . do_shortcode( $content ) … Read more
I can think of a couple of options: Create a new shortcode, e.g. my_gallery. You can copy the code in wp-includes/media.php. Look for the code staring with add_shortcode(‘gallery’, ‘gallery_shortcode’); and then the actual function. Rename / modify as needed. The actual img link is within the $link variable Use something like this (untested), which should … Read more
do_shortcodes_in_html_tags() runs attributes through wp_kses_one_attr() which checks them against wp_kses_allowed_html( ‘post’ ) which by default only accepts standard non-data attributes, so you’d have to add your attribute: add_filter( ‘wp_kses_allowed_html’, function ( $allowedposttags, $context ) { if ( $context == ‘post’ ) { $allowedposttags[‘a’][‘data-abc’] = 1; } return $allowedposttags; }, 10, 2 );
See the Shortcode API article on the Codex for a tutorial and my Shortcode Plugin for some examples. A very basic example for the functions.php: /** * Shortcode for bloginfo() * * Usage: [bloginfo key=”template_url”] * * @see http://codex.wordpress.org/Template_Tags/get_bloginfo * @source http://blue-anvil.com/archives/8-fun-useful-shortcode-functions-for-wordpress * @param array $atts * @return string */ function bloginfo_shortcode($atts) { extract( shortcode_atts( … Read more
As a test in the first conditional statement replace your //php comment in the else {} portion of your conditional with an actual echo statement to see whether the conditional is actually working properly, <?php if( is_page( 39 ) ) { // make your stuff here echo do_shortcode(‘[nggallery id=1]’); } else { echo ‘It works!’; … Read more
Referering to the Shortcodes API you can do echo do_shortcode(‘[helloworld]’); if your shortcode not in post. Or you can do echo apply_filters(‘the_content’, ‘[helloworld]’); but this will also bring other filters to work on your shorcode return html.
Good to hear that you managed to solve the problem already. Here’s a few examples on how you could also return html from a shortcode. As you already found out, you can use ob_start() and ob_get_clean() to buffer the html. Inside it you can echo the markup or drop out of PHP and write plain … Read more
