php redirect doesnt work

08/10/2007, 02h21

Hi,
I have a problem that I've been stuck on for while now.
Here is my code

<html>
<head>
<title>Login</title>
</head>
<body>
<h2>Login</h2>
<?php
if ( (isset($_POST['uname'])) && (isset($_POST['pass'])) ){
include '../dbConn.inc';
$uname = $_POST['uname'];
$pass = sha1($_POST['pass']);

$dbResult = mysql_query("select uid from users where
username='$uname' and password='$pass'", $dbh);
mysql_close($dbh);
if (mysql_num_rows($dbResult) < 1){
print "Invalid username or password.";
}else{
session_start();
$_SESSION['uid'] = mysql_result($dbResult, 0, 'uid');
header('Location: main.php');
}
}else{
?>
<form method="post" action="login.php">
<table border="0">
<tr>
<td>Username:</td>
<td><input type="text" name="uname" size="20"/></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="pass" size="20"/></td>
</tr>
<tr>
<td><input type="submit" value="Submit" name="login"/></td>
</tr>
</table>

</form>

</body>
</html>
<?php
}
?>

For some reason, the page doesn't get redirected to main.php. Can
anyone me with this.

ps. there is no spaces after ?> at the bottom of the code.

Thanks

Jack,

First of all, enable all errors and display errors in your PHP.INI file.
If you don't have access to this file, you can use ini_set to set
them, but it's much easier to do it in the php.ini file (also this way
works even if you have syntax errors in your code).

Once you get this, I'm pretty sure you'll get a message about "header
already sent...". I don't remember the exact message off hand (you'd
think I would, the number of times I've seen it! :-) ), but it comes
because you've send output before this time. It could only be blank
space - but you've sent SOME data.

And you should also get a message indicating "output started in file xxx
at line yyy". This is where you need to took to find why output has
previously been sent.

Jerry,
I'm not a coder, but in installing php scripts I've run into that "header
already sent" quite a number of times. For me, a non-coder, that meant I had
to dispense with the script and go look for another.
Do you know a reason or two "why?" - something that a non-coder might find
and fix?
Thanks in advance.

You see this HTML that is on the top of your page, it will prevent the
header() from work, as it has to be sent before any other output from a script.

You can try with adding ob_start() as the first thing on the page.

I agree.
Move this stuff:
<html>
<head>
<title>Login</title>
</head>
<body>
<h2>Login</h2>

so it's above the opening form tag.

one other thing you *might* have to watch out for is:-
"Note: HTTP/1.1 requires an absolute URI as argument to » Location:
including the scheme, hostname and absolute path, but some clients
accept relative URIs. You can usually use $_SERVER['HTTP_HOST'],
$_SERVER['PHP_SELF'] and dirname() to make an absolute URI from a
relative one yourself: "
(from <http://uk3.php.net/header>)

It means you've sent output (even white space) to the client before the
call to session_start() or similar call.

If you want to play with PHP, I highly recommend you learn some of the
basics. No language is completely "plug and play". There will be
problems at times, but most do not require an expert to fix. They do,
however, require someone with knowledge of the language.

You've already sent the HTTP headers. You can't send them twice. You
need to call 'header()' BEFORE you output anything or else it will not
work.
