Using wp_localize_scripts

Try this: function is_localized($tag) { global $wp_scripts; $data = $wp_scripts->get_data( $tag, ‘data’ ); return ! empty( $data ); }

You can add conditional statements inside the wp_enqueue_scripts action hook. add_action( ‘wp_enqueue_scripts’, function() { if( is_page( ‘page-slug’ ) ) { // Enqueued script with localized data. wp_enqueue_script( ‘register-validation-js’ ); } } ); You can refer to the is_page documentation for more information on what arguments can be pass.

A way around it … Read more

How does core do it? After thinking again about it, I thought there might be a case where WP does the same thing internally. And right: It does it. Example ~/wp-admin/load-scripts.php $wp_scripts = new WP_Scripts(); wp_default_scripts($wp_scripts); // inside wp_default_scripts( &$scripts ) $scripts->add( $handle, $src, $dependencies, $version, $args ); // from WP_Dependencies $scripts->localize( $handle, $object_name, $data … Read more

To successfully add variable to the window object via wp_localize_script you need to properly invoke three functions in the following sequence: wp_register_script wp_localize_script wp_enqueue_script In your case you’re missing the wp_register_script.
