监听器中的多个产品，贝宝 IPN

Question

我使用 paypal IPN 将信息发送到我的 php 代码，该代码将获取该信息并将附件产品发送到买家电子邮件。

我的问题是我是否可以在一个侦听器中拥有多个产品，或者我需要为每个产品提供单独的文件？

如果2个或更多客户同时购买产品，会不会有什么问题？ 就像只向其中一个而不是两个或更多发送附件一样。

	require "PHPMailer/PHPMailer.php";

		exit();

	$response = curl_exec($ch);

不，这样不会有问题。 IPN 数据将包含一系列购物车商品，因此您可以遍历这些商品并对每个商品执行您需要执行的任何操作。

您可能对我们的IPN template 感兴趣。现在有点过时了，但你可以see how we're preparing $cart_items into an array 很容易循环。

// Cart Items
$num_cart_items = isset($_POST['num_cart_items']) ? $_POST['num_cart_items'] : '';

$i = 1;
$cart_items = array();   
while(isset($_POST['item_number' . $i]))   
{   
    $item_number = isset($_POST['item_number' . $i]) ? $_POST['item_number' . $i] : '';   
    $item_name = isset($_POST['item_name' . $i]) ? $_POST['item_name' . $i] : '';   
    $quantity = isset($_POST['quantity' . $i]) ? $_POST['quantity' . $i] : '';  
    $mc_gross = isset($_POST['mc_gross_' . $i]) ? $_POST['mc_gross_' . $i] : 0;
    $mc_handling = isset($_POST['mc_handling' . $i]) ? $_POST['mc_handling' . $i] : 0;
    $mc_shipping = isset($_POST['mc_shipping' . $i]) ? $_POST['mc_shipping' . $i] : 0;
    $custom = isset($_POST['custom' . $i]) ? $_POST['custom' . $i] : '';   
    $option_name1 = isset($_POST['option_name1_' . $i]) ? $_POST['option_name1_' . $i] : '';   
    $option_selection1 = isset($_POST['option_selection1_' . $i]) ? $_POST['option_selection1_' . $i] : '';   
    $option_name2 = isset($_POST['option_name2_' . $i]) ? $_POST['option_name2_' . $i] : '';   
    $option_selection2 = isset($_POST['option_selection2_' . $i]) ? $_POST['option_selection2_' . $i] : '';
    $option_name3 = isset($_POST['option_name3_' . $i]) ? $_POST['option_name3_' . $i] : '';   
    $option_selection3 = isset($_POST['option_selection3_' . $i]) ? $_POST['option_selection3_' . $i] : '';
    $option_name4 = isset($_POST['option_name4_' . $i]) ? $_POST['option_name4_' . $i] : '';   
    $option_selection4 = isset($_POST['option_selection4_' . $i]) ? $_POST['option_selection4_' . $i] : '';
    $option_name5 = isset($_POST['option_name5_' . $i]) ? $_POST['option_name5_' . $i] : '';   
    $option_selection5 = isset($_POST['option_selection5_' . $i]) ? $_POST['option_selection5_' . $i] : '';
    $option_name6 = isset($_POST['option_name6_' . $i]) ? $_POST['option_name6_' . $i] : '';   
    $option_selection6 = isset($_POST['option_selection6_' . $i]) ? $_POST['option_selection6_' . $i] : '';
    $option_name7 = isset($_POST['option_name7_' . $i]) ? $_POST['option_name7_' . $i] : '';   
    $option_selection7 = isset($_POST['option_selection7_' . $i]) ? $_POST['option_selection7_' . $i] : '';
    $option_name8 = isset($_POST['option_name8_' . $i]) ? $_POST['option_name8_' . $i] : '';   
    $option_selection8 = isset($_POST['option_selection8_' . $i]) ? $_POST['option_selection8_' . $i] : '';
    $option_name9 = isset($_POST['option_name9_' . $i]) ? $_POST['option_name9_' . $i] : '';   
    $option_selection9 = isset($_POST['option_selection9_' . $i]) ? $_POST['option_selection9_' . $i] : '';

    $btn_id = isset($_POST['btn_id' . $i]) ? $_POST['btn_id' . $i] : '';

    $current_item = array(   
                           'item_number' => $item_number,   
                           'item_name' => $item_name,   
                           'quantity' => $quantity, 
                           'mc_gross' => $mc_gross, 
                           'mc_handling' => $mc_handling, 
                           'mc_shipping' => $mc_shipping, 
                           'custom' => $custom,   
                           'option_name1' => $option_name1,   
                           'option_selection1' => $option_selection1,   
                           'option_name2' => $option_name2,   
                           'option_selection2' => $option_selection2, 
                           'option_name3' => $option_name3, 
                           'option_selection3' => $option_selection3, 
                           'option_name4' => $option_name4, 
                           'option_selection4' => $option_selection4, 
                           'option_name5' => $option_name5, 
                           'option_selection5' => $option_selection5, 
                           'option_name6' => $option_name6, 
                           'option_selection6' => $option_selection6, 
                           'option_name7' => $option_name7, 
                           'option_selection7' => $option_selection7, 
                           'option_name8' => $option_name8, 
                           'option_selection8' => $option_selection8, 
                           'option_name9' => $option_name9, 
                           'option_selection9' => $option_selection9, 
                           'btn_id' => $btn_id
                          );   

    array_push($cart_items, $current_item);   
    $i++;   
} 

然后……

// Loop through cart items and add each to related order_items table
foreach($cart_items as $cart_item)
{
    $cart_item_data['order_id'] = $order_id;
    $cart_item_data['subscr_id'] = $subscr_id;
    $cart_item_data['item_name'] = $cart_item['item_name'];
    $cart_item_data['item_number'] = $cart_item['item_number'];
    $cart_item_data['os0'] = $cart_item['option_selection1'];
    $cart_item_data['on0'] = $cart_item['option_name1'];
    $cart_item_data['os1'] = $cart_item['option_selection2'];
    $cart_item_data['on1'] = $cart_item['option_name2'];
    $cart_item_data['os2'] = $cart_item['option_selection3'];
    $cart_item_data['on2'] = $cart_item['option_name3'];
    $cart_item_data['os3'] = $cart_item['option_selection4'];
    $cart_item_data['on3'] = $cart_item['option_name4'];
    $cart_item_data['os4'] = $cart_item['option_selection5'];
    $cart_item_data['on4'] = $cart_item['option_name5'];
    $cart_item_data['os5'] = $cart_item['option_selection6'];
    $cart_item_data['on5'] = $cart_item['option_name6'];
    $cart_item_data['os6'] = $cart_item['option_selection7'];
    $cart_item_data['on6'] = $cart_item['option_name7'];
    $cart_item_data['os7'] = $cart_item['option_selection8'];
    $cart_item_data['on7'] = $cart_item['option_name8'];
    $cart_item_data['os8'] = $cart_item['option_selection9'];
    $cart_item_data['on8'] = $cart_item['option_name9'];
    $cart_item_data['quantity'] = $cart_item['quantity'];
    $cart_item_data['custom'] = $cart_item['custom'];
    $cart_item_data['mc_gross'] = $cart_item['mc_gross'];
    $cart_item_data['mc_handling'] = $cart_item['mc_handling'];
    $cart_item_data['mc_shipping'] = $cart_item['mc_shipping'];
    $cart_item_data['raw_log_id'] = $ipn_log_data_id;
    $cart_item_data['btn_id'] = $cart_item['btn_id'];

    $cart_item_id = $db -> query_insert('order_items', $cart_item_data);
}

该示例准备要输入数据库的数据，但您应该能够将其应用于您正在做的任何事情。
