        $password=md5($_POST['password']);

        $query=$conn->query("select * from users where username='$username' and password='$password'");

        if ($query->num_rows>0) {
            $row=$query->fetch_array();
            if ($row['level']=="admin") {

Answer 1

Try to use 尝试使用

<input type ="submit" id="loginbutton">

instead of 代替

  <button type="button" id="loginbutton">

to post your form. 发布您的表格。

Answer 2

Change 更改

header('location: admin/index.php');

to 至

header('Location: agent/index.php');

it is an easy mistake to make 这是一个容易犯的错误

Answer 3

You forgot to define the method and action in form tag. 您忘记了在表单标签中定义method和action 。 The method attribute specifies how to send form-data. method属性指定如何发送表单数据。 When posting a form, it always good to have a method is post . 发布表单时，最好使用post方法。 As for action, a route or file location where action should perform. 至于动作，是应该执行动作的路径或文件位置。

So try this: 所以试试这个：

<form method="post" action="/{_action_filename_}.php">
