After linking to the pass.html page, create a pass.php file
Compare the entered original password with the password in the database. If it matches, then judge further. Use update to change the original password
The code is as follows:
<?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');
}
}
}
?>After writing, run it
As shown in the figure, it is found that the password of the database has been changed Modification successful
In this way, we have completed the function of changing the administrator password.
