You can pass variables to javascript using wp_localize_script function: https://codex.wordpress.org/Function_Reference/wp_localize_script Add the following to functions.php if(!function_exists(‘load_my_script’)){ function load_my_script() { global $post; $deps = array(‘jquery’); $version= ‘1.0’; $in_footer = true; wp_enqueue_script(‘my-script’, get_stylesheet_directory_uri() . ‘/js/my-script.js’, $deps, $version, $in_footer); wp_localize_script(‘my-script’, ‘my_script_vars’, array( ‘postID’ => $post->ID ) ); } } add_action(‘wp_enqueue_scripts’, ‘load_my_script’); And your js file (theme-name/js/my-script.js): jQuery(document).ready(function($) { … Read more
