wp_add_inline_script()

wp_add_inline_script() — Adds extra code to a registered script. Code will only be added if the script is already in the queue. Accepts a string $data containing the code. If two or more code blocks are added to the same script $handle, they will be printed in the order they were added, i.e. the latter added code can redeclare the previous.

Inputs: $handle (string): Name of the script to add the inline script to. $data (string): String containing the JavaScript to be added. $position (string): Optional. Whether to add the inline script before the handle or after. Default ‘after’.

Returns bool: True on success, false on failure.
