Use the admin_enqueue_scripts hook instead of admin_init Note: you should use hooks that target admin pages as specifically as possible. e.g.: Plugins: Use the admin_print_scripts-{plugin-page} hook Themes: Use the admin_print_scripts-{theme-page} hook (where {theme-page} is whatever string you use in the add_theme_page() call) Custom Post-Type Edit Page: Use the admin_print_scripts-edit.php hook, For Custom Post Types, inside … Read more
You have a basic mistake in your code. The following code if ( !is_page(‘my-page’) ) { means that if you are not on that page, deregister the scripts. Have a look at the php operators ! -> Not !$x True if $x is not true Also, why not exclude this specific page when you initially … Read more
The WordPress enqueue system should prevent the inclusion of the same script multiple times, and does when I test it. For example, the following enqueues a Core script and echos a counter. If I put this shortcode into a post 4 times, I get “0123” but the media script only loads one time. The same … Read more
RequireJS in custom theme. Working Example

This file is for list manipulations with jQuery: add, delete or dim list items. It was introduced in Ticket #4805 to replace some prototype code. Attached to the ticket is a sample plugin which holds the actual documentation. It doesn’t work really good … line 461 should be: $id = isset ( $_POST[‘id’] ) ? … Read more
The earliest safe hook to get post information is the template_redirect hook. All the hooks in question runs before WordPress has setup postdata, so any post info are still unavailable at that point. The globals like $wp_query and $post will still contain no data, that is why your efforts returns nothing. EDIT Extra info as … Read more
The tricky thing is knowing whether or not a particular script or style was enqueued by the theme. Themes and plugins both use the same hooks and functions, so they’re not explicitly labelled in any way as belonging to a specific theme or plugin. This means that the only way to know whether a script … Read more
Note: the file name is functions.php, not function.php (but that’s probably just a typo in the question). To remove a script or style, you must remove it after it was added. If you try to remove it before it was added, or even print $GLOBALS[‘wp_scripts’]->registered, nothing will happen, since it was not added yet. So … Read more
You can target a specific page using is_page() when you are enqueueing your JS file. function my_scripts_method() { if( is_page(‘your page title’) ){ wp_enqueue_script( ‘your-js-script’ ); } } add_action( ‘wp_enqueue_scripts’, ‘my_scripts_method’ ); This way, you will conditionally enqueue your JS to that page only.
