 * Hi. Can you help me please and tell what i’m doing wrong?
 * There is a function ub_releted_post_by_shop() ([https://pastebin.com/7WcBCcyq](https://pastebin.com/7WcBCcyq))
   that returns a list of posts from blog, this posts have the same taxonomy as 
   the current post type
 * If I call this function inside single post then everything is fine, I ‘ve got
   needed posts.
 * But when I’m on the homepage or in archive then this function returns wrong posts(
   not by taxonomy terms)
 * Frontpage is formed by index.php that has some templates for different post types(
   [https://pastebin.com/Xbc0QZvU](https://pastebin.com/Xbc0QZvU)).
 * Why function (code) returns wrong posts on homepage?
 * Thanks for advices.

 * It could be that `global $post` is unreliable. Maybe turn on [error logs via wp-config.php](https://codex.wordpress.org/Debugging_in_WordPress)
   and log the post object in your function when it’s wrong:
 *     ```
       global $post;
       error_log( print_r( $post, 1 ) );
       ```
   
 * It could be that one of your templates is calling WP_Query without resetting 
   the global $post. You could also try resetting the query at the top of your function
   before calling the global $post object:
 * `wp_reset_postdata()` should work but you could also call `wp_reset_query()` 
   and see if one of those solves the issue.

 * The result of error_log( print_r( $post, 1 ) );
    [https://pastebin.com/ESjCmeGF](https://pastebin.com/ESjCmeGF)
 *     ```
       function ub_related_post_by_shop() {
       	wp_reset_query();
       	//wp_reset_postdata();
       	global $post;
       	error_log( print_r( $post, 1 ) );
       	$post_terms = wp_get_object_terms($post->ID, 'shop', array('fields'=>'ids'));
       .....
       ```
   
 * wp_reset_query(); and wp_reset_postdata(); don’t solve the problem.
 * Here is my template [https://pastebin.com/te6mW98z](https://pastebin.com/te6mW98z)
   that is called from index.php ([https://pastebin.com/Xbc0QZvU](https://pastebin.com/Xbc0QZvU))
 * And this is content-header.php that is called from template [https://pastebin.com/L5KixpWV](https://pastebin.com/L5KixpWV)
 * Can you please take a look?
    Thanks.

 * Well, the issue is that in your `WP_Query()` you’re querying `post_type => 'post'`
   but in the error logged post the post type there is `promotion`. If you’re trying
   to just get `posts`, the `global $post` isn’t always going to be a post type 
   of post, sometimes it will be a page or whatever the post type of the current
   page is.
 * Check where `promotion` is being queried, if through a custom query make sure
   the `wp_reset_postdata()` is being called. If it’s a promotion page where the
   queried object is expected to be a promotion then you’ll need to rethink your
   function.
