init is much earlier than page template loading and not appropriate place for enqueues (despite many tutorials and docs using it for that). Hook your function to wp_enqueue_scripts and make sure you are doing that hooking before wp_head() call in template.
To extend on @gmazzap suggestion on not using globals when you can use wp_scripts(), there is a shortcut for wp_scripts() for adding conditional comments called wp_script_add_data and likewise wp_style_add_data for conditional styles. So the correct way to use conditionals as of WordPress 4.2 is like this: /** * IE enqueue HTML5shiv with conditionals * @link … Read more
When attempting to dequeue a script, we need to hook in after the script is enqueued, but before it’s printed. In this case, the Disqus plugin is using the wp_footer hook at a priority of 10 to enqueue the scripts. The footer scripts get printed during wp_footer at a priority of 20. So we should … Read more
There is a dequeue method available … I’m just not sure why it isn’t wrapped in a wp_dequeue_script() method. (I might create a ticket for this issue, actually) But yes, using wp_deregister_script will accomplish what you’re trying to do. Just remember, if you ever do want to use WP’s built-in jQuery later you’ll need to … Read more
I don’t know what your exact reason is for this, but you should scrap the idea of moving styles to the footer. If you though of a gain in speed, you might gain a unnoticable amount, if any, but that will be at the cost of other bigger things. Styles should always be added inside … Read more
wp_enqueue_style and wp_enqueue_script accepts many parameters and it’s very important to use them in correct order otherwise these functions will fail. Here are complete set of parameters for each function. wp_enqueue_style( $handle, $src, $deps, $ver, $media ); wp_enqueue_script( $handle, $src, $deps, $ver, $in_footer ); In your wp_enqueue_style you define $handle, $src correctly but $deps to … Read more
The accepted answer is completely wrong. I suspect a gross misunderstanding of the OP’S question, since anyone with even a little experience with programming will never recommend something like “cache your own copy of the script, and perform get_url calls every 20 minutes”. @Paul G. says there is no point in loading from the CDN … Read more
W3 Total Cache offers JS/CSS minification. I’m not familiar with the process they use, but if you are wanting to avoid using a plugin, you could take a look at their source code how they handle it.
Your CODE is fine, the reason you are getting 403 error is because $_SERVER[‘DOCUMENT_ROOT’] returns absolute PATH to your web root, not URL. JavaScript needs to be added as URL. So, you may use Load_Template_Scripts_wpa83855 function in your plugin and then use: wp_enqueue_script( ‘wtd’, plugins_url( ‘/js/wtd.js’ , __FILE__ ) ); CODE to add JavaScript. Note: … Read more
function script_that_requires_jquery() { wp_register_script( ‘script-with-dependency’, ‘http://www.example.com/script-with-dependency.js’, array( ‘jquery’ ), ‘1.0.0’, true ); wp_enqueue_script( ‘script-with-dependency’ ); } add_action( ‘wp_enqueue_scripts’, ‘script_that_requires_jquery’ ); This is the correct method to enqueue scripts (and styles for that matter). You should always be using wp_enqueue_scripts to hook scripts and styles to. There are a few thing here to check when you … Read more
