Anyway cou can do it easier - don't post to verify.php, but implement
the verify mechanism in login.php:
<?php
if (isset($_POST['user'])) {
$user = $_POST['user'];
$password = $_POST['password'];
$check = your_login_check_function($user, $password);
if ($check) {
$_SESSION['logged'] = $_POST['user'];
header("Location: your_welcome_page.php");
exit;
}
else {
$msg = "Login incorrect, try again!";
}
}
else {
$user = "";
$password = "";
$msg = "Please log in!";
}
?>
<html>
<head>
</head>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<h1><?php echo $msg; ?></h1>
<p>Username: <input type="text" value="<?php echo $user; ?>"
name="user"></p>
<p>Password: <input type="text" value="<?php echo $password; ?>"
name="password"></p>
<p><input type="submit" value="Send" name="send"></p>
</form>
</body>
</html>
