How to display Custom posts Type on a WordPress tag page

If your WordPress tag page isn’t showing post, pages or custom post types, it might be because WordPress, by default, only shows posts from the standard “post” type on tag archive pages. To display custom post types on tag archive pages, you’ll need to modify your theme’s functions.php file or create a custom plugin.

Here’s how you can fix it:

Step 1: Modify the Query to Include Custom Post Types

You can hook into WordPress’ pre_get_posts action to modify the query for the tag pages to include your custom post types. Add the following code to your functions.php file:

function include_custom_post_types_in_tag_archive($query) {
if ( $query->is_tag() && $query->is_main_query() && !is_admin() ) {
// Add your custom post types
$query->set( ‘post_type’, array( ‘post’, ‘your_custom_post_type’ ) );
}
}
add_action( ‘pre_get_posts’, ‘include_custom_post_types_in_tag_archive’ );

Step 2: Flush Rewrite Rules

After adding this code, flush your permalinks by going to Settings > Permalinks in the WordPress admin and simply click “Save Changes.”

Step 3: Check Your Custom Post Type Registration

When you registered your custom post type, ensure that it supports tags. In your register_post_type() function, make sure you’ve included 'taxonomies' => array('post_tag') in the arguments.

Step 4: Test Your Tag Archive

Visit one of your tag archive pages and see if the custom post type posts are showing up.
