我将更新 coeds_user 表，该表在插入发生时具有 userid autoincrement 属性，它会自动自动递增 1，然后在字段的其余部分插入相应的数据。到目前为止，我已经成功插入了该行，但是我的问题是当userid是autoincrement时如何更新这一行，请问如何实现autoincremented userid的update函数，先谢谢了。 插入搜索.php
<?php
$user="root";
$server="localhost";
$password="";
$db="coedsproddb1";
$dbconn= mysql_connect($server,$user,$password);
mysql_select_db($db,$dbconn);

最佳答案
您正在更新用户详细信息，现在您知道行的 id 字段。您可以使用 name="id"和 value="user_row_id"的隐藏输入字段显示更新表单。然后在您的代码中编写简单的 SQL 更新查询。
