Fix Add_Shortcode not Working – WordPress

Shortcode problem can be solved via override approach or by registering at init level. Possible problems would be,

  • Shortcode may already exists in a theme.
  • Register shortcode at init level.
  • Overrides previously registered short code.

Use “Remove_Shortcode” Approach:

Theme developer already register the code, remove it by remove_shortcode.

remove_shortcode('your_shortcode_name');

add_shortcode('your_shortcode_name','function');

Try Adding Shortcode at Init Level:

use add_action with init to add the code.

function abc(){
 add_shortcode('shortcode_name','function');
 }

add_action('init','abc');

Final Fix: Override all behavior of Shortcode:

May your shortcode exists already by the grace of core functionalities (e.g. gallery). You may try the following fix we are taking the example of Gallery shortcode.

  1. Remove the shortcode first.
  2. Enclose our code in a function.
  3. Use “add_action” to init the function at “init” level.
  4. Add a priority to load in the last. It may be any number e.g 9999

Example of Code:

 remove_shortcode('gallery', 'gallery_shortcode');
 add_action('init', 'add_my_gallery_shortcode', 99);
 function add_my_gallery_shortcode() {
      add_shortcode( 'gallery', 'my_gallery_shortcode');
 }
 function my_gallery_shortcode( $attr ) {
     // the new gallery logic here
 }

The number 99 is the priority for action to execute.  Higher priority executes in the end and overlap previous functionalities. Setting priority makes more possibility to overcome shortcode failure.
