Question

我试图删除ID为1的计数器000004，但每次我删除所有000004在我的数据库中删除的记录。有什么问题？

PURCHASE_ORDER

counter |  id  |

000004  |  1   |
000004  |  2   |
000007  |  3   |
000005  |  4   |

rfq.php

if(isset($_GET['de']))
{
$del_id=$_GET['de'];

$sql1 = $mysqli->query("DELETE FROM purchase_order WHERE counter ='$del_id'");

if($sql1)
{
echo '<script type="text/javascript">window.history.go(-1);</script>'; 
}
}

这是发送ID的链接

rfq_list.php

<td align="center"><a href="rfq.php?de='.$row["counter"].'" onclick="return confirm(\'Really want to delete ?\');"></a></td>

Answer 1

要指定多个删除条件，请使用AND：

DELETE FROM purchase_order WHERE counter = '000004' AND id = 1;

Answer 2

你可以尝试这样的事情。

<强> rfq_list.php

<td align="center"><a href="rfq.php?id='.$row["id"].'&&de='.$row["counter"].'" onclick="return confirm(\'Really want to delete ?\');"></a></td>

此处，与counter value一起，value of id传递了<a href>。

<强> rfq.php

if(isset($_GET['de']) && isset($_GET['id']))
{
$del_id=$_GET['de'];
$id=$_GET['id'];

$sql1 = $mysqli->query("DELETE FROM purchase_order WHERE counter ='$del_id'  and id='$id'");

if($sql1)
{
echo '<script type="text/javascript">window.history.go(-1);</script>'; 
}
}

delete值为counter 000004和id = 1的{{1}}记录。

不删除我在数据库中的记录
