Restrict Page Access Based on Purchased Products in WooCommerce

This code restricts access to specific pages based on whether the logged-in customer has purchased at least one product from a defined list.

Guests are blocked with an access message.

Logged-in users must have purchased any one of the allowed product IDs for that page.

If not, a message with a return link is shown.

Add this code to your theme’s functions.php or a custom plugin.

✅ Easy to update: just modify the $pages_products array to add more pages or product IDs
