) 

を使用して、カートの支払いを完了した後、item_name1ありますペイパルからのサンプル応答だと、これらの項目の値はのは、私が持っていた例を言わせて取得する方法をitem_name2 10項目を支払った？それは私がこの

<?php 
    $i = 1; 
    foreach($_SESSION['cart'] as $id => $qty): 
    $product = find_product($id); 
?> 

<input type="hidden" name="item_name_<?php echo $i; ?>" value="<?php echo $product['ProductDescription']; ?>"> 
<input type="hidden" name="item_number_<?php echo $i; ?>" value="<?php echo $product['ProductID']; ?>"> 
<input type="hidden" name="amount_<?php echo $i; ?>" value="<?php echo $product['ProductOverridePrice']; ?>"> 
<input type="hidden" name="quantity_<?php echo $i; ?>" value="<?php echo $qty; ?>"> 

<?php 
    $i++; 
    endforeach; 
?> 

のように、私のPHPコードを介して、項目の番号を生成し、サンプルPayPalの応答を見れば、mc_gross_1、mc_gross_2がある.​​..

をitem_name10するitem_name1からのようになります税金1、税金2など..どのように数字を増やしてその値をデータベースに保存するのですか？

Answer 1

でも、[num_cart_items] = 2もあります。 は、だから...

for ($i = 1; $i <= $_POST['num_cart_items']; $i++) { 
    $name = $_POST['item_name' . $i]; 
    $number = $_POST['item_number' . $i]; 
    $quantity = $_POST['quantity' . $i]; 
    //etc... 

    $query = "INSERT INTO payments (product_name, product_id, product_quantity) 
      VALUES ('" . mysql_real_escape_string($name) . "', '" . mysql_real_escape_string($number) . "', '" . mysql_real_escape_string($quantity) . "')"; 
    mysql_query($query); 
}
