I am trying to make a simple html website where you can login and save data to your account.
I have tried using MySQL and following this tutorial but it returns that MySQL is deprecated.
I have also found some code on stack overflow using php but I don’t know how to extract data and add data from that file with JavaScript.
<form action="login.php" method="post">
<input type="text" id="username" name="username"/>
<input type="password" id="password" name="password"/>
<input type="submit" name="Login" value="Login">
</form>
<html>
<head>
<title>Login</title>
</head>
<body>
<?php
//If Submit Button Is Clicked Do the Following
if ($_POST['Login']){
$myFile = "log.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = $_POST['username'] . ":";
fwrite($fh, $stringData);
$stringData = $_POST['password'] . "\n";
fwrite($fh, $stringData);
fclose($fh);
} ?>
//goes here after
<script>location.href='https://YOURWEBSITE.com';</script>
</body>
</html>
