Answer 1

首先在您的文件中添加错误报告：

error_reporting(-1);
ini_set('error_reporting', E_ALL);

注意这个条件：

if($res==$upass)

$res 将 returns 资源 ID 不能等于 $upass 因为 $upass 等于您的输入字段密码。

Second，请阅读 mysqli_query 的手册，您在查询中错过了 link 标识符，例如

mysqli_query($connectionLink,"Your query");

第三，如何将输入的密码与数据库值进行比较？

$res = mysqli_query($connectionLink, "SELECT Password FROM tbl_user WHERE Username='$uname'");
$row_cnt = mysqli_num_rows($res); // check the records

if($row_cnt){
    $row = mysqli_fetch_array($res); // fetch the data
    if($row['Password'] == $upass){ // check condition (bad practice)
        // your stuff
    }
}

第四，你在密码字段中保存的是简单字母吗？这不是一个好习惯，请始终使用加密密码。

密码散列手册：

password_hash (PHP 5 >= 5.5.0, PHP 7)

md5
