Question

I have just launched a site (using Joomla and a custom template), which doesn’t display that well in IE7 (and I guess below too). I have looked around and have found out that you can link to different style sheets from my index.php, however, instead of linking to a different style sheet, I want it to link to the older site which is still live (under www.mydomain.com/old).

Is that at all possible?

As stated in the title, I have looked around and found out that you could use an if statement like this –

<!-- [if lte IE 7]><"LINK TO OLD SITE"/><![endif]-->

is what I’m trying even possible? I haven’t got anywhere with it so far, trying the usual html tags of href="http://www.mydomain.com/old"

Any help would be great on this. I’m just getting stuck at the moment!

Conditional comments are used in the client-side part of your page, and so are not useful for PHP. You can use a conditional comment with JavaScript like this:

<!— [if lte IE 7]>
    <script type="text/javascript">
        top.location.href = "http://www.mydomain.com/old";
    </script>
<![endif]-->

The disadvantage of this is that you are performing this task on the client machine, which is slower than if you performed the redirect on the server and sent to user to a different page instead. You can do this using PHP by checking the browser version and redirecting with header:

$browser = get_browser();
if($browser->browser == 'IE' && $browser->majorver <= 7) {
    header('Location: http://www.mydomain.com/old');
}

Bear in mind that for this to work you must call header before any data is sent to the client.
