To run the hook, copy the example below.

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

The following example is for adding a hook callback.

// define the widget_update_callback callback 
function filter_widget_update_callback( $array, $int, $int ) { 
    // make filter magic happen here... 
    return $array; 
}; 
         
// add the filter 
add_filter( 'widget_update_callback', 'filter_widget_update_callback', 10, 3 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'widget_update_callback', 'filter_widget_update_callback', 10, 3 );
