How to improve body_class replacement with regular expressions

    Hello,

    I’d like to adjust body_class a bit to get shorter custom page template CSS class (example: page-main instead of page-template-page-main-php).

    My code performs the task but I feel it is not the most efficient way. Could you show how to refactor it?

    /**
 * Adjust body classes
 */
add_filter('body_class','my_template_class');
function my_template_class($classes) {
  foreach ( $classes as $key => $class_name ) {
    if ( preg_match( "/page-template-.*-php/", $class_name ) ) {
      preg_match( "/page-template-(.*)-php/", $class_name, $matches );
      $classes = array_replace( $classes, array($key => $matches[1]) );
    }
  }
  return $classes;
}

    Thank you.

    I think that’s pretty efficient. This will work also for the default page template which doesn’t have”-php” after the classname (“page-template-default”):

    add_filter('body_class','my_template_class');
function my_template_class($classes) {
  foreach ( $classes as $key => $class_name ) {
    $classes[$key] = preg_replace( "/^page-template-(.*?)(-php|)$/", '$1', $class_name );
  }
  return $classes;
}
