How can I restrict product access based on previous purchases in WooCommerce?

Determining Customer Purchases for Product Access Control

Problem Statement:

In WooCommerce, you need to restrict the ability to purchase specific products (c, d, e) unless the customer has previously purchased either product a or b. If this condition is met, the purchase buttons for products c, d, and e should be enabled; otherwise, they should remain disabled.

Solution:

Implement a conditional function to check if a customer has previously purchased designated products and leverage this function to control the visibility and functionality of purchase buttons for restricted products.

Code:

Add the following conditional function to your functions.php file:

function has_bought_items() {
    $bought = false;

    // Specify the product IDs of restricted products
    $prod_arr = array( '21', '67' );

    // Retrieve all customer orders
    $customer_orders = get_posts( array(
        'numberposts' => -1,
        '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 status "completed"
    ) );

    foreach($customer_orders as $customer_order) {
        // Compatibility for WooCommerce 3+
        $order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;
        $order = wc_get_order( $customer_order );

        // Iterate through purchased products in the order
        foreach($order->get_items() as $item) {
            // Compatibility for WC 3+
            if(version_compare(WC_VERSION, '3.0', '<')){
                $product_id = $item['product_id'];
            }else{
                $product_id = $item->get_product_id();
            }

            // Check if any of the designated products were purchased
            if(in_array($product_id, $prod_arr)){
                $bought = true;
            }
        }
    }

    // Return true if a designated product was purchased
    return $bought;
}

Copy after login

Usage:

In your relevant WooCommerce templates (e.g., loop/add-to-cart.php), you can use the has_bought_items() function to control the visibility and functionality of purchase buttons for restricted products:

// Replace restricted product IDs as needed
$restricted_products = array( '20', '32', '75' );

// Compatibility for WC +3
$product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

// Customer has not purchased a designated product for restricted products
if( !has_bought_items() && in_array( $product_id, $restricted_products ) ) {
    // Display inactive add-to-cart button with custom text
}else{
    // Display normal add-to-cart button
}

Copy after login

By implementing this conditional check, you can effectively prevent customers from purchasing restricted products until they have met the specified purchase requirement.
