Php redirection help

[jmmille]

Hi guys,

 

I'm trying to make a script that will read an url from an input box and redirect the user to this page via php.

 

This is what I have so far:

 

input.htm

<form method="post" action="redir.php">
<input type="text" name="redurl">
<input type="submit" value="Go!">

 

redir.php

<?
$url = $_POST['redurl'];
header('Location:'. $url);
?>

 

When I run this script I get this error:

Warning: Cannot modify header information - headers already sent by (output started at G:\Portable\xampplite\htdocs\redir\redir.php:2) in G:\Portable\xampplite\htdocs\redir\redir.php on line 6

 

Any help on this would be awesome -- I can't seem to fin anyway to do this without the header function and it's just not working for me.

<?
$url = $_POST['redurl'];
header('Location:'. $url);
exit;
?>

Thanks for the quick response.  That is better (no error).

 

Now I just need get the script to check for http://.. Thanks guys!

And if statement infront will probably do:

if($HTTP != 'on') {		header('Location: http://'.$URL);

Thanks for all the help guys!

 

I ended up with this code and it sees to be working correctly..

<?
$url = strtolower($_POST['redurl']);
if(strstr($url,'http://'))
{ header('Location:'. $url); }
else
{ header('Location:http://'. $url); }
exit;
?>
