To run the hook, copy the example below.

if ( !empty( $posts_columns ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the manage_<post_type>_posts_columns callback 
function filter_manage_post_type_posts_columns( $posts_columns ) { 
    // make filter magic happen here... 
    return $posts_columns; 
}; 
         
// add the filter 
add_filter( "manage_{$post_type}_posts_columns", 'filter_manage_post_type_posts_columns', 10, 1 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( "manage_{$post_type}_posts_columns", 'filter_manage_post_type_posts_columns', 10, 1 );
