I have created a simple HTML Login page. I have created a PHP file to transfer data to MySQL database(Using MySQL workbench 8.0) However, when I click submit, a page just open with some code from my PHP file and no data is transferred to my database. How can I transfer data from my Login page to my MYSQL database?

I have saved my PHP file in the C://

Code for Login Page:

<html>
   <head>
         <title>Login</title>
  </head>
   <body>
       <form action="/Test1.php">
        Username:<br>
        <input type="text" value="username"><br>
        Password:<br>
        <input type="text" value="password"><br>
        <input type="submit" value="submit"><br>
        </form>
    </body>
</html>

CODE for PHP:

<html>
<? php
$username = filter_input(INPUT_POST, 'username');
$password = filter_input(INPUT_POST, 'password');
if (!empty($username)){
if (!empty($password)){
    $host = "localhost:3306";
    $dbusername = "root";
    $dbpassword = "";
    $dbname = "login";

    // Create Connection
    $conn = new mysqli ($host, $dbusername, $dbpassword, $dbname);
    if (mysql_connect_error()){
        die ( 'Connect Error ('.mysqli_connect_errno().')'.mysqli_connect_error());
    }
    else {
        $sql = "INSERT INTO login.user (username, password)
        values ('$username', '$password')";
        if ($conn->query($sql)){
            echo "New record is inserted successfully";
        }
        else {
            echo "Error:".$sql."<br>".$conn->error;
        }
        $conn->close();
}
}
else { 
echo "Password should not be empty";
die ();
}

else {
    echo "Username should not be empty";
    die();
}

?>
</html>

I expect data from HTML file to be inputed in MYSQL Database but instead a new page open up with this:

query($sql)){ echo "New record is inserted successfully"; } else { echo "Error:".$sql."
".$conn->error; } $conn->close(); } } else { echo "Password should not be empty"; die (); } else { echo "Username should not be empty"; die(); } ?>

php+mysql、用户登录界面,
