To run the hook, copy the example below.

$post_data = apply_filters( 'attachment_fields_to_save', $post_data, $attachment_data ); 
                         
if ( !empty( $post_data ) ) { 
                         
   // everything has led up to this point... 
                         
} 
  

The following example is for adding a hook callback.

// define the attachment_fields_to_save callback 
function filter_attachment_fields_to_save( $post_data, $attachment_data ) { 
    // make filter magic happen here... 
    return $post_data; 
}; 
         
// add the filter 
add_filter( 'attachment_fields_to_save', 'filter_attachment_fields_to_save', 10, 2 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'attachment_fields_to_save', 'filter_attachment_fields_to_save', 10, 2 );
