我正在寻求一项限制，如果访客用户在一周内购买了特定产品两次，他就不能再次购买相同的产品。
我希望根据访客用户的电子邮件应用此限制。
我看过很多与此相关的帖子，但都专注于注册用户，但我想对访客用户应用此限制。
这是我当前正在使用的代码，不幸的是没有达到预期的结果
function my_ip_checker() {
$last_order = get_posts(array(
//'date_created' => '>=' . (time() - 86400), time in seconds
'meta_key' => '_billing_email',
'meta_value' => sanitize_email( $_POST['cb_email'] ),
'post_type' => 'shop_order',
'post_status' => array('wc-processing', 'wc-completed')
));
if($last_order->total > 1) {
wc_add_notice('Too many orders in the last 24 hours. Please return later.', 'error');
}
}
add_action('woocommerce_checkout_process', 'my_ip_checker', 10, 0);
如有任何帮助，我们将不胜感激。
对于每周特定产品的限制，您可以使用：
wc_get_ordersfunction action_woocommerce_checkout_process() {
// Initialize
$customer_email = '';
// Get email
if ( is_user_logged_in() ) {
// Get current user
$user = wp_get_current_user();
// Get email
$customer_email = $user->user_email;
} elseif ( isset( $_POST['billing_email'] ) && ! empty ( $_POST['billing_email'] ) ) {
$customer_email = $_POST['billing_email'];
} else {
// Get billing_email
$customer_email = WC()->customer->get_billing_email();
}
// NOT empty
if ( ! empty ( $customer_email ) ) {
// Time in seconds (1 week)
$time_in_seconds = 604800;
// Set limit per week
$limit = 2;
// Specific product id
$specific_product_id = 30;
// Get orders from last week from customer by email
$orders_last_week_by_customer_email = wc_get_orders( array(
'date_created' => '>' . (time() - $time_in_seconds ),
'customer' => $customer_email,
));
// Total (counter)
$total = 0;
// Iterating through each order
foreach ( $orders_last_week_by_customer_email as $order ) {
// Going through order items
foreach ( $order->get_items() as $item ) {
// Get product ID
$product_id = $item->get_product_id();
// Compare
if ( $specific_product_id == $product_id ) {
// Get quantity
$quantity = $item->get_quantity();
// Add to total
$total += $quantity;
}
}
}
// Show error when total >= limit
if ( $total >= $limit ) {
wc_add_notice( sprintf( __( 'You are not allowed to buy more than %d pieces of product with ID = %d in one week', 'woocommerce' ), $limit, $specific_product_id ), 'error' );
}
}
}
add_action( 'woocommerce_checkout_process', 'action_woocommerce_checkout_process', 10, 0 );
仅将此应用于访客用户：
更换
// Get email
if ( is_user_logged_in() ) {
// Get current user
$user = wp_get_current_user();
// Get email
$customer_email = $user->user_email;
} elseif ( isset( $_POST['billing_email'] ) && ! empty ( $_POST['billing_email'] ) ) {
$customer_email = $_POST['billing_email'];
}
与
// Only for guests
if ( ! is_user_logged_in() ) return;
if ( isset( $_POST['billing_email'] ) && ! empty ( $_POST['billing_email'] ) ) {
$customer_email = $_POST['billing_email'];
}
对于每周特定可变产品的限制，我使用：
wc_get_ordersWC_Order_Queryfunction action_woocommerce_checkout_process() {
$specific_product_name = 'Buy iPhone 12 with Z Protect+ included';
// Only for guests
if ( is_user_logged_in() ) return;
//product check start
global $woocommerce;
$parent_id;
$_product = '';
$items = $woocommerce->cart->get_cart();
foreach($items as $item => $values) {
$_product = wc_get_product( $values['data']->get_id());
}
$parent_id = $_product->get_parent_id();
if( $parent_id == 389 ){
//product check end
// Isset
if ( isset( $_POST['billing_phone'] ) ) {
// NOT empty
if ( ! empty ( $_POST['billing_phone'] ) ) {
$customer_phone = $_POST['billing_phone'];
}
}
// Isset
if ( isset ( $customer_phone ) ) {
// Time in seconds (1 week)
$time_in_seconds = 604800;
// Set limit per week
$limit = 2;
// Specific product name
$specific_product_name = 'Buy iPhone 12 with Z Protect+ included';
// Get orders from last week from customer by phone
$orders_last_week_by_customer_phone = wc_get_orders( array(
'date_created' => '>' . (time() - $time_in_seconds ),
'billing_phone' => $customer_phone,
));
$total = 0;
// Iterating through each order
foreach ( $orders_last_week_by_customer_phone as $order ) {
// Going through order items
foreach ( $order->get_items() as $item ) {
// Name of the producte
$product_name = $item->get_name();
// Compare
if ( $specific_product_name == $product_name ) {
// Add to total
$total += 1;
}
}
}
// Show error when total >= limit
if ( $total >= $limit ) {
wc_add_notice( sprintf( __( 'You are not allowed to buy more than %d iPhones. For more information please contact support.', 'woocommerce' ), $limit ), 'error' );
}
}
// Isset
if ( isset( $_POST['billing_email'] ) ) {
// NOT empty
if ( ! empty ( $_POST['billing_email'] ) ) {
$customer_email = $_POST['billing_email'];
}
}
// Email NOT empty
if ( ! empty ( $customer_email ) ) {
// Time in seconds (1 week)
$time_in_seconds = 604800;
// Set limit per week
$limit = 2;
// Specific product id
$specific_product_id = 'Buy iPhone 12 with Z Protect+ included';
// Get orders from last week from customer by email
$orders_last_week_by_customer_email = wc_get_orders( array(
'date_created' => '>' . (time() - $time_in_seconds ),
'customer' => $customer_email,
));
// Total (counter)
$total = 0;
// Iterating through each order
foreach ( $orders_last_week_by_customer_email as $order ) {
// Going through order items
foreach ( $order->get_items() as $item ) {
// Get product ID
$product_id = $item->get_name();
// Compare
if ( $specific_product_id == $product_id ) {
// Get quantity
$quantity = $item->get_quantity();
// Add to total
$total += $quantity;
}
}
}
// Show error when total >= limit
if ( $total >= $limit ) {
wc_add_notice( sprintf( __( 'You are not allowed to buy more than %d iPhones. For more information please contact support.', 'woocommerce' ), $limit), 'error' );
}
}
//product check start
}
//product check start
}
add_action( 'woocommerce_checkout_process', 'action_woocommerce_checkout_process', 10, 0 );
感谢上面的第一个答案为我提供了开始实施的基础。 欢迎对我的代码进行任何进一步的改进。
该脚本运行良好，但如果客户之前购买了特定产品，则不允许他购买任何其他产品。
该脚本只是检查客户是否之前购买了特定产品并阻止他的订单。我添加了一个额外的条件来检查他是否正在尝试购买特定产品或其他东西。
if( WC()->cart->find_product_in_cart( WC()->cart->generate_cart_id( $specific_product_id ) ) ) {
此代码位于此行之前
// Show error when total >= limit
限制访客客户仅使用计费电话号码，在 WooCommerce 中的特定时间范围内多次购买任何产品，最佳代码是什么
