在 WooCommerce 中限制客户在特定时间范围内多次购买特定产品

Question

如果来宾用户在一周内购买了特定产品 2 次，我正在寻找限制，他不能再购买相同的产品。

我希望根据来宾用户的电子邮件应用此限制。

我看过很多与此相关的帖子，但都关注注册用户，但我想对来宾用户应用此限制。

这是我目前使用的代码，遗憾的是没有得到想要的结果

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);

感谢任何帮助。

Answer 1

对于每周特定产品的限制，您可以使用：

基于账单电子邮件地址
wc_get_orders 提供检索订单的标准方法 - wc_get_orders and WC_Order_Query
将适用于来宾用户或登录用户

function 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 );

仅对来宾用户应用此：

替换

// 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'];  
}

有

// Only for guests
if ( ! is_user_logged_in() ) return;

if ( isset( $_POST['billing_email'] ) && ! empty ( $_POST['billing_email'] ) ) {
    $customer_email = $_POST['billing_email'];  
}

Answer 2

对于每周特定可变产品的限制，我使用了：

我使用父产品 ID 来限制来宾用户：
基于账单电子邮件地址
基于phone个数
wc_get_orders 提供检索订单的标准方法 - wc_get_orders 和 WC_Order_Query

function 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。
