    function filter_ajax(){



    $category = $_POST['category'];



   

     $args = array(

             }

The category id is delivered, but it is not clear to me why the products of this selected category are not displayed

             $loop = new WP_Query($args);

             if($loop->have_posts()):

             while ( $loop->have_posts() ) : $loop->the_post(); global $product; 

             ?>

My Answer:
There could be several reasons why the products are not being shown. Some possible reasons include:

1. The products may not be properly added to the database or the database connection may be incorrect.
2. There may be an issue with the code that retrieves and displays the products on the website.
3. The products may be out of stock or have been set to not display on the website.
4. There could be a problem with the server or hosting environment that is preventing the products from being displayed.
5. There may be a caching issue that is preventing the products from being updated or displayed correctly.

To troubleshoot the issue, you can check the database connection, review the code that retrieves and displays the products, check the product settings in the backend of the website, and ensure that there are no server or caching issues causing the problem.
