I have build a function to fetch a post in Wordpress served over ajax.

        url: '/wp-admin/admin-ajax.php',
        type: 'POST',
        cache: false,
        data: {
          action: 'get_post_info',
          postId: postId,
        success: function(data){


In order to make it work if the user is not logged in, I have used wp_ajax_nopriv. But when the user is logged in now, the functionality crashes.

add_action('wp_ajax_nopriv_get_post_info', 'get_post_info');
function get_post_info(){

Is there a function like wp_ajax that work for both logged_in and not logged_in users?

  • It is best practice to declare a ajaxurl variable for non administration side usage. On the administration side ajaxurl is defined, see note here.

add_action('wp_ajax_get_post_info', 'get_post_info');
add_action('wp_ajax_nopriv_get_post_info', 'get_post_info');

wp_ajax_nopriv_(action) only on front-end and only for non logged users. Use wp_ajax_(action) for logged in users.


As it is said in the codex The wp_ajax_nopriv hook will not fire for authenticated users, i.e. when is_user_logged_in() returns true. To handle both unauthenticated and authenticated users, also use wp_ajax_(action).
