Redirection Problem

Topspin · Topspin

I'm running PHP on Windows, but that's just the local test... in production
it will be on Apache.

I am not using PHP as a CGI. I want to perform redirection of the user's
browser if the user isn't a valid user. I don't want to use the refresh
meta tag or javascript to do this. I want to do this with some sort of
server command.

Does anyone know how to make this work? Here's my code...
<?php
session_start();
$goal = "";
if (array_key_exists('goal', $_GET)) { $goal = $_GET['goal']; }

if (isset($HTTP_POST_VARS['userid']) && isset($HTTP_POST_VARS['password']))
{
$userid = $HTTP_POST_VARS['userid'];
$password = $HTTP_POST_VARS['password'];
$db_conn = mysql_connect('localhost', 'webauth', 'webauth');
mysql_select_db('auth', $db_conn);
$query = "select * from auth where name='$userid' and
pass=password('$password')";
$result = mysql_query($query, $db_conn);
if (mysql_num_rows($result) > 0) {
$HTTP_SESSION_VARS['valid_user'] = $userid;
}
}
?>
<?
if (isset($HTTP_SESSION_VARS['valid_user'])) {
// redirection code goes here. Re-direct to value current to the value of
$goal which is a html file in the current directory http directory

} else {
if (isset($userid)) {
echo 'Could not log you in';
} else {
echo 'You are not logged in <br/>';
}

echo '<html><body><form method="post" action="authmain.php">';
echo '<table>';
echo '<tr><td>Userid:</td><td><input type="text" name="userid"></td></tr>';
echo '<tr><td>Password:</td><td><input type="password"
name="password"></td></tr>';
echo '<tr><td colspan="2" align="center"><input type="submit" value="Log
In"></td></tr>';
echo '</table></form></body></html>';
}
?>

Hi Topspin,

just set the http-location-header like so:

header("location: $newurl");

The users browser should then load this new URL.
Make sure -as usual with the call to header- that your script
did not write anything out prior to the function call.
A simple blank somewhere in an included file is sufficient to let your
call fail.

Cheers

Upon finding out that they're not valid:

header("Location: http://www.getouttahere.com");

Make sure you write this BEFORE your script produces any output. Even a single
space will cause you grief. Also, be sure to use an absolute URL. Relative
URLs will work in some newer browsers, but cause trouble in others.

Hi there, I am new to contribute. I have set up a new index page for my website
however it is still redirecting to an old page that was filling a gap while the
new page was being built. Unfortunately the page it redircts to was not made by
us and is under a domain owned by someone else. What setting do I need to
change in order to stop the automatic redirection?
Cheers.
