  • 0

This block of code shown below using a php header redirect works locally, but not on my Bluehost server:

if ($_POST['submit']=='No')
{
    $url ='Location: index.php?id='.$id.'&page='.$page;
    header($url);
    exit;
}

When the server gets to this block of code, absolutely nothing happens. No error, no warning, just a blank page. The page that my form submit redirects to isn’t supposed to do anything except reroute the user to the relevant page.

I’m pretty dang positive it has nothing to do with the common problem of including HTML before the redirect (since it works locally). Therefore I suspect it has something to do with differences between my php.ini files. I’ve pulled up PHPinfo() for both servers, and my local server has a module named mod_headers while my Bluehost server has none. I think this potentially could be the problem, although normally my Bluehost has no problems using header redirects, except in this one instance.

So I suspect the problem has something to do with my ini file, but I don’t know exactly what.

What makes this problem even stranger is that there are other blocks of code which work just fine, for instance 

if(!empty($_POST['id']))
{
    $id = htmlentities(strip_tags($_POST['id']));
    $sql = "UPDATE entries SET title=?, entry=? WHERE id=? LIMIT 1";
    $stmt = $db->prepare($sql);
    $stmt->execute(array($title,$entry,$id));
    $stmt->closeCursor();
    $url= 'Location: ../index.php?id='.$id.'&page='.$page;
    header($url);
    exit;
}

works just great.

    I had the same problem that it works fine on XAMPP but not on bluehost or 1&1.

    PHP documentation says there should be no output before calling the header function.
    http://php.net/manual/en/function.header.php

    In my case there was a space before the opening <?PHP which made the header function not work.

    This should help to solve the problem.

    The quesiton remains though: why does it work on XAMPP and not on the servers of bluehost, 1&1, etc?
    (since I use firefox for both tests – it is definitely not a browser issue)
