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

The following example is for adding a hook callback.

// define the nf_email_notification_attachment_types callback 
function filter_nf_email_notification_attachment_types( $array ) { 
    // make filter magic happen here... 
    return $array; 
}; 
         
// add the filter 
add_filter( 'nf_email_notification_attachment_types', 'filter_nf_email_notification_attachment_types', 10, 1 ); 

To remove a hook callback, use the example below.

// remove the filter 
remove_filter( 'nf_email_notification_attachment_types', 'filter_nf_email_notification_attachment_types', 10, 1 );
