php - 产品 ID 未存储在数据库中

Question

有人可以帮忙吗？我的代码似乎没有在我的代码中存储产品 ID 的值，看看我还从另一个表获取 ID

    <?php
include("Connection.php");
$dTime = time();
$myValue = $_REQUEST['dValue'];
echo "<p>
The time is: {$dTime}<br/>
The choice is {$myValue}
</p>
";



$sql = "Select ID from product where NAME = '$myValue'";

$result = mysql_query($sql);
while ($row = mysql_fetch_assoc($result)) 
    $pid=$row["PRODUCT_ID"];



$sql2 = "INSERT INTO  `starbucks`.`order_details` (
`ID` ,
`ORDER_ID` ,
`PRODUCT_ID` ,
`QTY`
)
VALUES (
NULL ,  '',  '$pid',  '1'
)";

$result2 = mysql_query($sql2);
?>

更新了代码

Answer 1

$id = $row["ID"]

而不是:

$id = $row;
