Check if a script/style was enqueued/registered

Is it possible to test whether a script or a style was registered using wp_register_script/_style or wp_enqueue_script/_style? All functions doesn’t return a value and I’m completely clueless.

I need it to switch between different functions depending on stylesheet-libraries and scripts I offer.

Thank you!


There is a function called wp_script_is( $handle, $list ). $list can be one of:

  • ‘registered’ — was registered through wp_register_script()
  • ‘queue’ — was enqueued through wp_enqueue_script()
  • ‘done’ — has been printed
  • ‘to_do’ — will be printed

Ditto all that for wp_style_is().
