To run the hook, copy the example below.

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

The following example is for adding a hook callback.

// define the widget_title callback 
function filter_widget_title( $instance_title, $instance, $this_id_base ) { 
    // make filter magic happen here... 
    return $instance_title; 
}; 
         
// add the filter 
add_filter( 'widget_title', 'filter_widget_title', 10, 3 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'widget_title', 'filter_widget_title', 10, 3 );
