WordPress Get the Page ID outside the loop
If you're using pretty permalinks, get_query_var('page_id') won't work.
Instead, get the queried object ID from the global :$wp_query
// Since 3.1 - recommended!$page_object = get_queried_object();$page_id = get_queried_object_id();// "Dirty" pre 3.1global $wp_query;$page_object = $wp_query->get_queried_object();$page_id = $wp_query->get_queried_object_id();
You can also create a generic function to get the ID of the post, whether its outside or inside the loop (handles both the cases):
<?php/** * @uses WP_Query * @uses get_queried_object() * @see get_the_ID() * @return int */function get_the_post_id() { if (in_the_loop()) { $post_id = get_the_ID(); } else { global $wp_query; $post_id = $wp_query->get_queried_object_id(); } return $post_id;} ?>And simply do:
$page_id = get_the_post_id();
