 * I have four custom post types, and am using the following code snippet (using
   WPCode) to display them all at the same time in one query loop:
 *     ```wp-block-code
       function filter_specific_query_loop($query) {    // Check if this is an admin query or not the main query    if (is_admin() || !$query->is_main_query()) {        return;    }    // Check for the presence of the custom query parameter    if (isset($query->query_vars['custom_query_loop']) && $query->query_vars['custom_query_loop']) {        // Modify the query to include multiple post types        $query->set('post_type', array('post', 'restaurants', 'activities', 'equipment','recipes'));    }}add_action('pre_get_posts', 'filter_specific_query_loop');// Add a filter to include the custom query parameter when rendering the blockfunction add_custom_query_var($block_content, $block) {    if ($block['blockName'] === 'core/query') {        if (isset($block['attrs']['className']) && strpos($block['attrs']['className'], 'custom-query-loop') !== false) {            add_filter('query_vars', function ($query_vars) {                $query_vars[] = 'custom_query_loop';                return $query_vars;            });        }    }    return $block_content;}add_filter('render_block', 'add_custom_query_var', 10, 2);
       ```
   
 * I added custom class name: custom-query-loop to the query loop (located on home
   page). When I preview my page however, I only see one post type from the query
   loop.
 * Am I doing something wrong? My site is not live yet.
 * Thank you in advance for help!

 * Query loop queries are generally not main queries, so `|| !$query->is_main_query()`
   is preventing your code from modifying the query. The actual main query is for
   the page or post the query loop is on. Remove the `!` not operator so your code
   can alter the query loop query.

 * Thanks for the advice! I tried removing the `!` not operator, as well just deleting`
   || !$query->is_main_query()`, but still only see one post type when previewing
   my page in either case. Do you have any other thoughts?

 * Nothing more than basic debugging really. Verify the query var “custom_query_loop”
   that you’re checking for is really set. But first be sure debug output is visible
   on the page. If not you may need to use `error_log()`.
 * If the query var is not set, there could be an issue with add_custom_query_var()
   and not filter_specific_query_loop() where my attention has been focused.
 * Maybe it’s possible “pre_get_posts” fires before “render_block”, so your method
   of identifying the right query to modify might be flawed? (unverified)
 * Check the query object’s `request` property, the actual SQL query. There could
   be some other constraint that’s preventing non-post types from being returned.

 * add custom post type vars to your query code since it does not recognize as a
   post.
