错误
only 1 item stored.
嗨，您需要纠正此问题： '.$cart[$i]->image.'
for ($i=0; $i<count($cart); $i++) {
mysql_query("INSERT INTO order_details VALUES ('.$orderid.', '.$cart[$i]->name.', '.$cart[$i]->price.', '.$cart[$i]->quantity.', '.$cart[$i]->image.', '.$cart[$i]->price * $cart[$i]->quantity.','.$order.')");
}
另外，下次您提出此类问题时，请在代码中突出显示错误行。
