限制客户每年在 WooCommerce 中购买一次

Question

我使用此编码来限制用户每年创建订单，并且效果良好。但是，我注意到，如果最后一个订单的创建日期超过 365 天，编码会采用今年的日期，因此不会让购买时间超过 365 天的用户再次购买。有人可以检查编码并进行必要的修改吗？预先感谢！

function new_order_allowed() {
    if( ! ( is_cart() || is_checkout() ) ) return;

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

        $last_order = wc_get_customer_last_order( $user_id );

        if ( $last_order ) {
            $date_created = $last_order->get_date_created()->format( 'z' ) + 1;
            $current_time = current_time( 'z', true ) + 1;
            $year_in_day = 365;
            $days_passed = $current_time - $date_created;

            if ( $days_passed < $year_in_day ) {
               wc_add_notice( sprintf( '<b>ONLY ONE PURCHASE IS ALLOWED WITHIN 365 DAYS. </b><br>Your last order was %1$s days ago. Please try again when the 365 day period has been reached. ',  $days_passed ), 'error' );

                remove_action( 'woocommerce_proceed_to_checkout','woocommerce_button_proceed_to_checkout', 20);
            }
        }
    }
}
add_action( 'woocommerce_check_cart_items', 'new_order_allowed' );

Answer 1

为什么不以简单的方式来做呢？

$dateFrom = new DateTime('2023-05-01');
$dateTo = new DateTime('2024-05-01');

echo $dateFrom->diff($dateTo)->days;

这样

$dateFrom->diff($dateTo)->days;

将为您返回两个日期之间的天数。

尝试以下基于时间戳的修改后的代码：

add_action( 'woocommerce_check_cart_items', 'new_order_allowed' );
function new_order_allowed() {
    if ( is_user_logged_in() && ( is_cart() || is_checkout() ) ) {
        $last_order = wc_get_customer_last_order( get_current_user_id() );

        if ( is_a( $last_order, 'WC_Order') ) {
            $created_timestamp = $last_order->get_date_created()->getTimestamp();
            $allowed_timestamp = strtotime('-1 year');
            $days_difference   = floor(($created_timestamp - $allowed_timestamp) / DAY_IN_SECONDS);
            $days_passed       = 365 - $days_difference;

            if ( $created_timestamp <= $allowed_timestamp ) {
                wc_add_notice( sprintf( 
                    __('<strong>ONLY ONE PURCHASE IS ALLOWED WITHIN 365 DAYS.</strong><br>Your last order was made %s days ago. Please try again when the 365 day period has been reached.'),
                $days_passed ), 'error' );

                remove_action( 'woocommerce_proceed_to_checkout','woocommerce_button_proceed_to_checkout', 20);
            }
        }
    }
}

应该可以。
