Adding scripts to the WordPress login or registration form

22nd November 2009

Most WP developers know by now that the right way to add script libraries from a plugin or theme is to use the wp_enqueue_script function. It makes sure scripts aren’t loaded more than once, and so on.

However, I just had some problems getting some jQuery to run on the login / registration form. I used wp_enqueue_script like a good WP developer but… no go. Where’s my jQuery?

It seems the answer lies in the fact that after scripts are enqueued in a normal WP page, they get spit out by something inside the call to wp_head(). I guess you could add wp_head() to the login header, but who wants all those redundant plugin scripts and styles that (presumably) aren’t even meant to be there.

After a bit of digging around it seems that the solution is the wp_print_scripts() function. So, to get jQuery working on the login form, put these lines in the code you hook onto login_head:

wp_enqueue_script( 'jquery' );
wp_print_scripts();
