Question

我想从用户输入中选择产品以图表产品来购买我的网站产品，但有关mysqli_fetch_array的错误。我不知道如何解决此错误

   <?php
$total=0;
if(!empty($_SESSION['cart']))
{
    include("Config.php");
    foreach($_SESSION['cart'] as $pid2=>$qty)
    {
        $sql = "select * from product where pid=$pid2";
        $query = mysqli_query($con, $sql);
        $row = mysqli_fetch_array($query) ;

        $sum = $row['price'] * $qty;
        $total += $sum;
        echo "<tr>";
        echo "<td width='334'>" . $row["pname"] . "</td>";
        echo "<td width='46' align='right'>" .number_format($row["price"],2) . "</td>";
        echo "<td width='57' align='right'>";  
        echo "<input type='text' name='amount[$pid2]' value='$qty' size='2'/></td>";
        echo "<td width='93' align='right'>".number_format($sum,2)."</td>";
        //remove product
        echo "<td width='46' align='center'><a href='cart.php?pid=$pid2&act=remove'>ลบ</a></td>";
        echo "</tr>";
    }
    echo "<tr>";
    echo "<td colspan='3' bgcolor='#CEE7FF' align='center'><b>ราคารวม</b></td>";
    echo "<td align='right' bgcolor='#CEE7FF'>"."<b>".number_format($total,2)."</b>"."</td>";
    echo "<td align='left' bgcolor='#CEE7FF'></td>";
    echo "</tr>";
}
?>
