wp_print_scripts

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

Description

(array) wp_print_scripts( (bool) $handles = false ); 

Called by admin-header.php and 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 hook to register/enqueue new scripts.

Returns (array)

On success, a processed array of WP_Dependencies items; otherwise, an empty array.

Parameters (1)

0. $handles — Optional. (bool) => false
Scripts to be printed. Default false..
