所以我刚刚开始学习PHP并且正在按照一个旧的指南来制作我感兴趣的东西。整个指南都使用了旧的弃用的mysql函数,所以我决定冒险尝试PHP的小经验并尝试修复我自己。我决定迁移到mysqli,因为它似乎比PDO更容易替代。一切似乎都运行良好,直到我意识到我的用户登录不太正常。以下是我设置的方法:
$password = md5($_POST['user_password']);
$sql = "SELECT * FROM users
WHERE user_email = '$user_email'
AND user_password = '$password'";
$result = mysqli_fetch_assoc($link->query($sql));
$_SESSION['user_id'] = $result['user_id'];
$_SESSION['user_acl_id'] = $result['user_acl_control_id'];
$_SESSION['user_first_name'] = $result['user_first_name'];
$_SESSION['user_last_name'] = $result['user_last_name'];`
每当我尝试通过登录输入密码时,即使它是正确的,它也会告诉我我错了。我怀疑我的问题在这一行内:
$result = mysqli_fetch_assoc($link->query($sql));
指南原来是这样的:
$password = md5($_POST['user_password']);
$sql = "SELECT * FROM users WHERE user_email = '$user_email' AND user_password = '$password'";
$result = mysql_fetch_assoc(mysql_query($sql));
$_SESSION['user_id'] = $result['user_id'];
$_SESSION['user_acl_id'] = $result['user_acl_control_id'];
$_SESSION['user_first_name'] = $result['user_first_name'];
$_SESSION['user_last_name'] = $result['user_last_name'];
如果有人能帮助我,我将不胜感激!提前谢谢!

这样说吧
$result = mysqli_fetch_assoc(mysqli_query($con,$sql));
将$con
替换为您的连接名称
