防止用户每月购买超过 2 个产品（wp/woo）

Question

是否有人有 woocommerce 结帐验证的示例，如果他们在过去 30 天内已经购买了 2 种产品，我可能会失败验证？

我似乎找到的只是输入字段的 javascript 验证，但我最好在 PHP 中完成更复杂的验证。

非常感谢！

您可以使用 woocommerce

woocommerce_checkout_process

钩子来防止。将此代码添加到您的活动主题functions.php 文件中。

function prevent_users_from_buying_more_than_two_products_per_month() {

    $user_id = 0;

    if ( is_user_logged_in() ) {
        
        $user_id = get_current_user_id();

    } else {

        $user_email = isset($_POST['billing_email']) ? sanitize_email($_POST['billing_email']) : '';

        $user = get_user_by('email', $user_email);

        if ($user) {
            $user_id = $user->ID;
        }
    }

    if( $user_id ){

        $max_products_allowed = 2;
        $thirty_days_ago = date('Y-m-d H:i:s', strtotime('-30 days'));

        $args = array(
            'post_type'      => 'shop_order',
            'post_status'    => 'wc-completed', // Only consider completed orders
            'posts_per_page' => -1,
            'meta_query'     => array(
                array(
                    'key'     => '_customer_user',
                    'value'   => $user_id,
                    'compare' => '=',
                ),
                array(
                    'key'     => '_completed_date',
                    'value'   => $thirty_days_ago,
                    'compare' => '>',
                    'type'    => 'DATE',
                ),
            ),
        );

        $query = new WP_Query($args);

        $num_products_purchased = $query->post_count;

        if ($num_products_purchased >= $max_products_allowed) {
            wc_add_notice('You have already purchased ' . $num_products_purchased . ' products in the last 30 days.', 'error');
        }
    }
}
add_action('woocommerce_checkout_process', 'prevent_users_from_buying_more_than_two_products_per_month ');
