   hi,

   I have a page that calls my custom plugin. In this plugin I am trying to get the current page ID,

   function hook_ajax_register() {
   global $wp_query;
   check_ajax_referer($this->nonce_key_register, '_wpnonce', true); // die on failure
   // Get the form data
   parse_str($_POST['data'], $data);
   
   $thePostID = $wp_query->post->ID;
   $this->ref_code = get_post_meta($thePostID, 'ReferenceID', true);
   
   .....etc
   }

   If I change the post Id to a particular post(say 75) it works, however trying to retrieve the current post id where the plugin is called is not working!
   Please help

   $postID = $post->ID;

   this doesnt seem to work aswell!
   Could it be that it is because Im calling it within the plugin?

   I don't know. Have you tried print_r($post) and see what comes out? When stuff doesn't do what I expect, I find var_dump() or print_r() helps me figure it out immensely - let's me see what's being grabbed, and if I'm calling the incorrect variable.

   Thanks for your reply!
   I did the following
   

   function hook_ajax_register() {
   global $wp_query
   $thePostID = $wp_query->post->ID;
   $this->marketing_code = get_post_meta($thePostID, 'ReferenceID', true);

   However I am now getting a zero value?

   any ideas?

   Thanks again

   first off, you're missing a semi-colon after your global.

   global $wp_query

   should be

   global $wp_query;

   Secondly, what I suggested is you globalize the $post - you're not doing that, so $post->ID will result in nothing.

   function hook_ajax_register() {
   global $post;
   $thePostID = $post->ID;
   $this->marketing_code = get_post_meta($thePostID, 'ReferenceID', true);

   try that.

   Hi,

   I am using below code in my plugin:

   global $post;
   $postID = $post->ID;

   This is not under any function, but this seems to not work... This is also not working:

   get_the_ID();

   Is there something i am missing (file, function etc) ?

   Any help on this will be appreciated...

   Thanks,
   Harpinder
