这篇我们介绍管理员密码是如何修改的，展示页面我们已经看到了，修改，链接到pass.html页面
这个就是修改的页面

链接到pass.html页面之后，创建一pass.php的文件
输入的原密码和数据库中的密码进行判断比较，如何符合，则往下判断，用update去修改原密码
代码如下：
<?php
require_once("../config/config.php");
mysql_query("set names = utf8");
$sql = "SELECT * FROM admin";
// if($_GET){
// $id = $_GET['id'];
// $sql0 = 'select username from user where id ='.$id;
// $result =mysql_query($sql0);
// $username = mysql_fetch_assoc($result)['username'];
// }
if($_POST){
$oldpassword = $_POST ["mpass"];
$newpassword = $_POST ["newpass"];
$confirm = $_POST['renewpass'];
$sql1 = 'select password from admin where id=1 ';
$result1 = mysql_query($sql1);
$password = mysql_fetch_assoc($result1)['password'];
if ($oldpassword !== $password) {
echo "与原密码不符";
}
else{
if ($newpassword==$confirm) {
$sql2 = 'UPDATE admin SET `password`="'.$newpassword.'" where id =1';
mysql_query ($sql2);
header('location:./usermessage.php');
}
}
}
?>
写完之后，运行一下
如图，发现数据库的密码已经修改成功
这样，我们就完成了修改管理员密码的功能。
