WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

According to the Codex, it should only be used for inline script tag(s) in the head. I've been using add_action('admin_print_scripts-{my-hook}' for injecting .js and add_action('admin_print_styles-{my-hook}' for .css without any problems. I use wp_register_script() & wp_enqueue_script() (and the corresponding *_style() ) to enqueue them.

A "view source" shows

<link rel='stylesheet' href=[...] />


<script type='text/javascript' src=[...] ></script>

being inserted into the <head> correctly.

Does anyone know any reason not to use them this way, other than a poorly-written Codex description that says not to?

The Problem if you just output the scripts (thats what the admin_print_scripts is for) is that you may end up having the same Javascriptfile included multiple times, which can lead to errors on your page.

If you use the wp_enqueue_script() WordPress checks if the requested Javascriptfile is already in the Queue, and what dependencies it relies on, so that they are included in the right order.

The admin_print_scripts should only be used to output the data.

There are a few ways to make the same things work (you could also hardcode the include into your files - but do not do that) - but you should always do it in the way it is suggested by WordPress - to ensure future compatibility and everything else WordPress offers.

Thanks, fischi. As noted in my Question, I already do use wp_register_*() as well as wp_enqueue_*(). I use the hooks admin_print_scripts-{my-hook} and admin_print_styles-{my-hook} to call them. I've seen these hooks used in more than one tutorial (can't remember where/too lazy to search), so I was wondering if anyone knows why the Codex says not to use them. Again, that particular part of the Codex is poorly written, so it calls into question its canonical-ness. –  akTed Jan 16 '13 at 10:59
@AKTed the reason you may want to use another hook is that you could enqueue your Javascript earlier. Does not really make a difference in the outcome, but the later you call an enqueue_script, the less there are possibilities to dequeue the script, if needed. Always depends on what you want to achieve, but enqueueing AFTER admin_print_scripts would be pointless ;) –  fischi Jan 16 '13 at 11:25
