  1. Gets the current screen object
  2.  
  3. <?php
  4. if ( !function_exists( 'get_current_screen' ) ) {
  5.   require_once ABSPATH . '/wp-admin/includes/screen.php';
  6. }
  7.  
  8. $result = get_current_screen();
  9. print_pre($result);
  10. ?>
  11.  
  12. Very handy for hoking into acf/save_post actions where acf-option-pages have no IDs
