我编写了一个基本脚本，允许用户编辑他们的注册详细信息

表单中的字段由登录用户的数据填充。当我试图保存记录时，出现以下错误：

Query was: UPDATE ccusers SET forename='admin', surname='admin', username='admin',
password='admin', email='admin@gmail.com' WHERE id='Array' AND 'admin'='admin'. Error:

在查询的这个阶段，它不会提取id

$editid = mysql_real_escape_string($_POST['editid']);
$Query = "UPDATE ccusers SET forename='$forename', surname='$surname',
username='$username', password='$password', email='$email' WHERE id='$editid'
AND '$user'='$user'";

我已经从Delete和editid输入中删除了type hidden，它们都显示了数组

<input name="Delete" value="<?php echo $id;?>">
<input name="editid" value="<?php echo $id;?>"/>

使用$id=$row['id']而不是$id[]。
查看错误语句中id列限定符的值，它读取“Array”，表示$editid变量是一个数组。尝试改用$editid[0]，或者更好的方法是使用val_转储变量，以帮助确定为什么变量是数组而不是字符串或整数。为什么这里的id=“$editid”
和“$user”=“$user”“您将“$user”=“$user”放在“尝试列名user=“$user”谢谢。我在输入中看到了id，但仍然得到一个错误。查询是：更新ccusers SET forename='admin'，姓氏='admin'，用户名='admin'，密码='admin'，电子邮件='admin'admin@gmail.com'其中id='5'和'admin'='admin'。错误：在where子句中取消引用列名admin。谢谢。我明天再看一遍。
