Extend LinkCentral with Hooks

Developers can extend LinkCentral functionality using hooks. The following hooks are available:

Link Clicks & Redirect

linkcentral_link_clicked – Action hook fired when a LinkCentral link is clicked. No further validations have happened at this point, such as a check if the link is a draft, set as private, scheduled for the future, or password protected. 

The hook passes:

  • The link ID
  • The link slug
  • The full link post object
				
					/**
 * @param int $link_id The ID of the clicked link
 * @param string $slug The slug of the clicked link
 * @param WP_Post $link The full link post object
 */
add_action('linkcentral_link_clicked', function($link_id, $slug, $link) {
    // Access post data from the link object
    $title = $link->post_title;
    $created_date = $link->post_date;
    
    // Perform custom operations with the link data
    my_custom_function($link_id, $title);
}, 10, 3);

linkcentral_before_redirect – Action hook that is triggered right before a valid link is redirected. All checks have passed. The hook passes: 

  • The link ID
  • The link slug
  • The final destination URL
  • The redirection type
  • The full link post object
				
					   /**
    * @param int $link_id The ID of the link
    * @param string $slug The slug of the link
    * @param string $destination_url The final destination URL
    * @param int $redirection_type The HTTP redirection code (301, 302, 307)
    * @param WP_Post $link The full link post object
    */
   add_action('linkcentral_valid_link_redirect', function($link_id, $slug, $destination_url, $redirection_type, $link) {
       // Send data to an external analytics system
       my_analytics_service::track_outbound_link([
           'link_id' => $link_id,
           'slug' => $slug,
           'destination' => $destination_url,
           'user_id' => get_current_user_id()
       ]);
   }, 10, 5);
