I'm using the Bones theme, and I'm trying to turn jQuery plugins into WordPress plugins. In the init.php file for the 'Chosen' plugin I'm converting, I've included this code:

function chosen(){
    wp_register_script("chosen-script",plugins_url( 'js/chosen.jquery.min.js' , __FILE__ ));
    wp_register_style("chosen-style",plugins_url( 'css/chosen.css' , __FILE__ ));

add_shortcode('chosen', 'chosen');

Google PageSpeed came back with this error:

Put CSS in the document head (1):

Link node chosen.css should be moved to the document head in www.blank.com/

How can I include this CSS file in the header?

    You should hook the function that registers and enqueues the scripts onto wp_enqueue_script. add_action( 'wp_enqueue_scripts', 'chosen' ); rather than as a shortcode. Mar 7, 2014 at 23:43
  • Thank you Andrew, that did it. The only problem is that now the plugin in loaded on every page of my site. With 'add_shortcode', the plugin was loaded only on pages that contained the 'chosen' shortcode. Is there a way without 'if' statements to include the plugin only on specific pages?

  • In regards to my last question, this is how I would load it on a specific page: if (is_page('to-do_list'))

  • To dynamically load stylesheets in the head based on a shortcode, you will have to do something like this which is admittedly a bit processing heavy.

By the time the shortcode is evaluated as part of the_content the header of the site has already been assembled. This makes it impossible to load scripts or styles in the header anymore.

As s_ha_dum suggests you could pre-process the whole post in the head of the file, but that would probably consume more resources than indiscriminately adding the js+css files to the header.

Another, also quite elaborate, approach would be to hook into save_post and set a postmeta flag indicating whether the shortcode is used in the post. You could then read the flag while still in the head and include the js+css files.
