wp_print_scripts() WP 2.1.0

Prints scripts in document head that are in the $handles queue.

Called by admin-header.php and 'wp_head' hook. Since it is called by wp_head on every page load, the function does not instantiate the WP_Scripts object unless script names are explicitly passed. Makes use of already-instantiated $wp_scripts global if present. Use provided 'wp_print_scripts' hook to register/enqueue new scripts.

  • See: WP_Scripts::do_items()
  • Global. WP_Scripts. $wp_scripts The WP_Scripts object for printing scripts.
Hooks in function
