How can I check a user bought something before?

Thanks.

Yes it is possible creating a conditional function that return true when a customer has already at least one order with status completed.

Here is the code for this conditional function:

function has_bought() {
    // Get all customer orders
    $customer_orders = get_posts( array(
        'numberposts' => 1, // one order is enough
        'meta_key'    => '_customer_user',
        'meta_value'  => get_current_user_id(),
        'post_type'   => 'shop_order', // WC orders post type
        'post_status' => 'wc-completed', // Only orders with "completed" status
        'fields'      => 'ids', // Return Ids "completed"
    ) );

    // return "true" when customer has already at least one order (false if not)
   return count($customer_orders) > 0 ? true : false; 
}

This code is tested and works.

This code goes in function.php file of your active child theme or theme, or in a plugin php file.

USAGE (as a condition):

• You can use it in some WooCommerce templates that you will have previously copied to your active child theme or theme.
• In your theme php files.
• In plugin php files.
• Any php function or WordPress/WooCommerce.
