Php & Internet Explorer, Part One

[Jetteh22]

Hello,

Some of you might remember me. I've finally gotten back into web building, etc, and I just can't figure this out. I test on Chrome, Firefox and IE. A couple of my PHP codes aren't working for IE ONLY... I'll put them in two separate threads since they're different questions.

The following code is supposed to make sure, on every page, that the page the person is coming from is within the site (no outside linking):

CODE

<?php

$myurl = "thinkcreactive.com";
$myurl2 = "www.thinkcreactive.com";

$referer = $_SERVER['HTTP_REFERER'];

if ($referer == "") {
$domain = $myurl;
} else {
$domain = parse_url($referer);
}

if($domain['host'] == $myurl || $domain['host'] == $myurl2) {

} else {

echo ?>

<script type="text/javascript">
<!--
window.location = "index.php?e=18"
-->
</script>
<?php

die();

}
?>

Now, on Chrome and Firefox you can go from page to page to page and it works fine. But on IE, it ALWAYS goes to the index page and gives the message I want it to give if you're linking in from outside.

Anybody know why it's doing this on IE only?

HTTP_REFERER is a browser set header - you can't rely on it for anything. Some set it, some don't, some even allow you to change it.

My personal method of doing this would be by sessions (which then relies on cookies)..., or by IP (with MySQL backup).

Heyyy, I remember you!

I actually do use sessions. My thing is, I don't want people to be able to link into my forms and my pages from their own site. With sessions and cookies, as long as you're in the same window you can log into the site, go to your own site ,click a link and it will take you back into MY site again and that's what I'm trying to avoid.

The referring URL is the perfect solution except for IE shit.

I've never left, just gotten quieter...

The referring URL is the perfect solution except for IE shit.

And the fact that it's not reliable. If people figure it out (and they will) they'll just spoof the referrer.
