PHP重复SQL条目X次数量

Question

我有一个电子商务商店，我正在建立，我需要购买的每件商品都是在数据库中输入的。例如，某人购买了2的数量，我需要重复SQL数据输入，因此它有两个条目。看下面的代码，让我知道我可以如何使用product_qty来实现这一点。

if (isset($_SESSION["cart_products"])) 
{ 
    $total = 0; //set initial total value 
    $b = 0; //var for zebra stripe table 
    foreach ($_SESSION["cart_products"] as $cart_itm) 
    { 
     $product_name = $cart_itm["product_name"]; 
     $product_qty = $cart_itm["product_qty"]; 
     $product_price = $cart_itm["product_price"]; 
     $product_code = $cart_itm["product_code"]; 
     $product_color = $cart_itm["product_color"]; 
     $subtotal = ($product_price * $product_qty); //calculate Price x Qty 
     $name = $_SESSION['firstName']. ' ' .$_SESSION['lastName']; 

     mysqli_query(
      $mysqli, 
      "INSERT INTO Order_Tickets 
        (sku, tktproduct, tktprice, purchaser) 
      VALUES ('$product_code','$product_name','$product_price','$name')" 
     ) or die(mysqli_error()); 
    } 

} 

Answer 1

你可以这样做吗？

if ($product_qty > 1) 
{ 
    for ($i = 0; $i <= $product_qty; $i++) 
    { 
     mysqli_query($mysqli, "INSERT INTO Order_Tickets (sku, tktproduct, tktprice, purchaser) VALUES ('$product_code','$product_name','$product_price','$name')") 
    } 
}
