Yes, you can use get_template_directory_uri to refer to the theme root path. <script type=”text/javascript” src=”https://wordpress.stackexchange.com/questions/244554/<?php echo get_template_directory_uri();?>/js/amplitude/amplitude.js”></script> But prefered way of doing is to use wp_enqueue_script().
In theory youtube embedding is done as iframes, and iframe are virtual additional independent web pages which are rendered at the same window, therefor the content of one iframe can not gave an impact on other iframes. In practice, such JS will be cached in the browser. The first one may get loaded, but the … Read more
You actually don’t need to worry about conflicting with the admin pages anymore. There is a “wp_enqueue_scripts” hook that makes sure the scripts aren’t called on admin pages. From WP Codex: <?php function my_scripts_method() { wp_deregister_script( ‘jquery’ ); wp_register_script( ‘jquery’, ‘http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js’); wp_enqueue_script( ‘jquery’ ); } add_action(‘wp_enqueue_scripts’, ‘my_scripts_method’); ?> But if you need a custom jQuery … Read more
By Using wp_enqueue_script() You can add your scripts to a JS file and then enqueue it properly. I assume you have added your scripts to file.js. Here’s how you enqueue it in the footer: add_action(‘wp_enqueue_scripts’,’my_script_callback’); function my_script_callback(){ wp_enqueue_script( ‘my-script’, get_template_directory_uri().’/folder/file.js’, array(jquery), null, true ); } The last argument in wp_enqueue_script() determines whether your script should … Read more
From your comment above I read This is one of the reason why i am looking for a way to say to wordpress: “hey, i added those js files, dont worry”. This is whole purpose of this question I think is perfectly fair, I +1ed your Q but the problem is that way does not … Read more
I would suggest creating a function named b99_register_scripts() and hook this into init. Then you can create another function named b99_enqueue_scripts() and hook it into wp_print_scripts.
Here’s a version that uses wp_localize_script(), as suggested by others. It’s just a little bit cleaner, since you don’t mix your PHP with your JS, and generally a neat way to pass things from the server side to your JavaScript. First, put the following code either in your plugin or your functions.php (I use a … Read more
First, you have nasty typo in __contsruct. 🙂 Second, your hook timing is wrong. Related WP JavaScript is localized via postL10n object (you can see it echoed in page’s source), that gets put together on init hook – way earlier then admin_head and your filter is not in place yet. From quick test this should … Read more
You have to filter script_loader_src, check if you are on the correct script and add a one-time filter for clean_url. Then add your extra script, and make sure the output is syntactically valid. Pretty simple, albeit rather hacky. class Extra_Script { private $extra = []; private $handle; private $url; private $versioned_url; public function __construct( $handle, … Read more
If you take a look at registrations in source there is no alias to load all of jQuery UI in bulk available and WP core itself uses pieces as dependencies individually. You could create and use such alias yourself (registered script handle with no URL and all of needed scripts as dependencies), but it might … Read more
