redirect confusion

[envexlabs]

Hey,

 

I know how to redirect using header(), but i have a quick question.

 

I know that you have to send the redirect before all the header information, but if i have a form being processed halfway down  the page  via, $_SESSION[php_self], how do i go about redirecting after the form has been processed?

 

Thanks,

<?

$username = $_post['username'];
$password = $_post['password'];

if (isset($username) && isset($password)) {
   mysql_query(update db set password = '$password', username = '$username' where id = userid);
}

header ("location:http://www.site.sufix/folder");

?> 

 

This is the way to redirect such a script

ummm, yes.

 

I'm not sure what the problem is? can you restate? you can use session variables before a header();

I know how to redirect, but the form is being processed half way down the page, after all the header has been rendered.

if that's the problem, move processing to the top before output. if there is a chance that you might need header(), you HAVE to do it before ANY information goes to the browser. that is the only way, there is no (decent) option.
