Usage

To run the hook, copy the example below.

$data = apply_filters( 'wp_update_attachment_metadata', $data, $post_id ); 
                         
if ( !empty( $data ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the wp_update_attachment_metadata callback 
function filter_wp_update_attachment_metadata( $data, $post_id ) { 
    // make filter magic happen here... 
    return $data; 
}; 
         
// add the filter 
add_filter( 'wp_update_attachment_metadata', 'filter_wp_update_attachment_metadata', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'wp_update_attachment_metadata', 'filter_wp_update_attachment_metadata', 10, 2 );
