If you hook your localize script function to wp_enqueue_scripts
, then you will have access to the global $post
variable. As long as you pick a hook at or after ‘wp’ you should have access to the global $post
.
<?php
add_action('wp_enqueue_scripts', 'YOUR_NAME_scripts');
function YOUR_NAME_scripts() {
wp_enqueue_script('YOUR_NAME-js');
global $post;
$params = array(
'site_url' => site_url(),
'admin_ajax_url' => admin_url('admin-ajax.php'),
'post_id' => $post->ID
);
wp_localize_script( 'jquery', 'YOUR_NAME', $params );
}
