Adding Custom Javascript to Skeleton Child Theme

One problem: if you define the script in a wp_register_script() like so: wp_register_script( ‘jquery.imagemapster.js’, get_template_directory_uri() . ‘/javascripts/jquery.imagemapster.js’, array(‘jquery’), ‘1.2.6’, false ); …then you only need to reference the defined script’s name in the wp_enqueue_script() call, like so: wp_enqueue_script( ‘jquery.imagemapster.js’ ); Re-declaring all of the parameters in wp_enqueue_script() shouldn’t cause the fatal error you describe; however, … Read more

Dynamically Load Styles and Scripts from Theme Functions.php

A couple issues here… First, the init hook is too early for WordPress to know which page template you’re going to be using. (So the is_page_template() function will always return false).

Wp_head and wp_footer vs wp_enqueue_script javascript files?

$wp_styles->registered not giving ALL the styles?

In addition, you can filter the URL before it is printed: add_filter( ‘script_loader_src’, function( $url ) { if ( 0 !== strpos( … Read more
