Login page: PHP header erorr

**menre** · Apr 4th, 2012, 04:29 AM

Hi Folks,

I am having trouble with my phph login page. When I enter the correct username and password, I get the error message below.

Code:

Warning: Header may not contain more than a single header, new line detected. in C:\xampp\htdocs\2012\login.php on line 9
You are being redirected to your original page request!
(If your browser doesn't support this, click here)

It is pointing to line 9 which I noticed starts with header and the full code for the login page is the one below. I will appreciate if someone could sport my mistake and suggest corrections please.

Code:

 <?php
session_start();
$_SESSION['logged'] = 0;

if (isset($_POST['submit'])) {
  if ($_POST['username'] == "nations" && 
      $_POST['password'] == "united") {
    $_SESSION['logged'] = 1;
    header("Refresh: 5; URL=" . $_POST['redirect'] . "");
    echo "You are being redirected to your original page request!<br>";
    echo "(If your browser doesn't support this, " .
         "<a href=\"" . $_POST['redirect']. "\">click here</a>)";
  } else {
?>
<html>
<head>
<title>Working with  PHP and MySQL</title>
</head>
<body>
<p>
  Invalid Username and/or Password<br><br>
  <form action="login.php" method="post">
    <input type="hidden" name="redirect"
      value="<?php echo $_POST['redirect']; ?>">
    Username: <input type="text" name="username"><br>
    Password: <input type="password" name="password"><br><br>
    <input type="submit" name="submit" value="Login">
  </form>
</p>
<?php
  }
} else {
?>
<html>
<head>

<body>
<p>

<?
if (isset($_GET['redirect'])) {
  $redirect = $_GET['redirect'];
} else {
  $redirect = "index.php";
}
?>
  <form action="login.php" method="post">
    <input type="hidden" name="redirect" 
      value="<?php echo $_GET['redirect']; ?>">
    Username: <input type="text" name="username"><br>
    Password: <input type="password" name="password"><br><br>
    <input type="submit" name="submit" value="Login">
  </form>
</p>
<?php
}
?>
</body>
</html>

Thanks in advance.
