wp_register_script() is for telling WordPress about script files, and is a PHP function. It has no control over how the script executes, only where the <script></script> tag is output and what the URL is. If you don’t want the script to execute until the page is loaded you need to put that JavaScript you posted … Read more
The error message describes your problem quite clearly: Notice: wp_deregister_script was called incorrectly. Do not deregister the jquery script in the administration area. To target the front-end theme, use the wp_enqueue_scripts hook. You’re de-registering the script on the init hook: add_action(‘init’, ‘replace_jquery’); This hook runs for the back and front end, but the debugger isn’t … Read more
You need wp_footer() call in your footer, before closing body tag. Theme without it is pretty much considered broken, since things like footer scripts simply can’t work without it.
There are several fundamental problems with what you’re trying to do that prevent you reaching your goal The Problems Naming You register 2 scripts, but you name them both ‘custom’. How is WordPress supposed to know which script you meant when you later tell it to display ‘custom’? /* Register scripts. */ wp_register_script( ‘custom’, JS … Read more
First, you’re attempting to deregister too late. You need to use wp_enqueue_scripts, rather than wp_print_scripts. Second, all you need to do is add a call to wp_deregister_script() for each script you need to deregister: <?php add_action( ‘wp_enqueue_scripts’, ‘my_deregister_javascript’, 100 ); function my_deregister_javascript() { if ( !is_page(array(‘order’, ‘shopping-cart’, ‘checkout’) ) ) { wp_deregister_script( ‘tcp_scripts’ ); // … Read more
Ahh ok I figured it out while researching. I needed to add the $hook parameter and pass it to my function like so: function my_admin_enqueue_scripts($hook) { global $current_screen; if ( ‘post.php’ != $hook ) return; wp_register_script(‘my-scripts’, get_template_directory_uri() . ‘/js/custom/my-scripts.js’ ); wp_enqueue_script(‘my-scripts’); wp_localize_script(‘my-scripts’, ‘wp_ajax’, array( ‘ajaxurl’ => admin_url( ‘admin-ajax.php’ ))); } This gave me the results … Read more
You can hook the wp_footer action to output arbitrary JavaScript. This the same action that WordPress uses to output footer enqueued scripts. Here’s an example that encapsulates the shortcode, data, and script output in a class: <?php /* Plugin Name: WPD_Example */ class WPD_Example_Plugin { public $data = array(); function __construct() { add_shortcode( ‘wpd_example’, array( … Read more
When you call google, the key variable name is missing. wp_register_script( ‘googlemap’, ‘https://maps.googleapis.com/maps/api/js?123123123123’ , ”, ”, false ); Should be : wp_register_script( ‘googlemap’, ‘//maps.googleapis.com/maps/api/js?key=123123123123123123123123’ , ”, ”, false );
Page is created and output in the following order: header, content, footer. Shorcode is executed during the construction of the page content, when header is already output on the page. So, it is impossible to add any script to header on this stage: it is too late.
I think that none the options you has posted actually works. You are only registering the script, you need to enqeue them. Also, you should use wp_enqueue_scripts() action hook instead of init(). function register_scripts() { wp_register_script( ‘newsletter’, get_stylesheet_directory_uri() . ‘/scripts/scripts.js’, array( ‘jquery-migrate’ ), null ); wp_enqeue(‘newsletter’); } add_action( ‘wp_enqueue_scripts’, ‘register_scripts’ );
