Blackberry redirect?

This site is best viewed in a modern browser with JavaScript enabled.

Hi everyone. I'm trying to find some script to redirect Blackberries to our mobile site automatically. I found some javascript that works for iPhones - it just reads the screen width (<=699) and redirects with document.location="http://www.mymobilesite.htm". But this doesn't work with Blackberries. Here's the statement I'm trying.

I'd heard that Blackberries don't read javascript at all, but I found this code out there - plus the Blackberry site says that useragent detection in javascript should work! Maybe it's just a syntax error?

I'm not working with PHP or anything fancy and good, just HTML.

So I'm baffled. If it's just plain impossible, how come no one seems to say that either?

Thanks everyone. Hope someone can help.

<script type="text/javascript">
onload=function(){
if ((screen.width <= 800) || (navigator.user[B][COLOR="Blue"]A[/COLOR][/B]gent.match(/blackberry/i)) {
[B][COLOR="Blue"]window[/COLOR][/B].location.[B][COLOR="Blue"]href[/COLOR][/B] = "mypageurlhere.htm";
}
}
</script>

But for Blackberry in WAP/WML modes, the code above might not work, as I believe that in those cases JavaScript is disabled. Or if the JavaScript is disabled you can not use a JavaScript code, can you?

A server-side solution looks more reliable.

Sigh. Yeah, I think most Blackberries either have javascript disabled or don't have it at all. I'll try a server-side solution - I think there's a PHP page I can get to to put an all-purpose redirect on.

Speaking of which, do you (or does anyone) know some good code for that? I've found a few solutions - one is to stick something like this in the .htaccess file:

1.#redirect mobile browsers
2.RewriteCond %{HTTP_USER_AGENT} ^.iPhone.$
3.RewriteRule ^(.)$ http://mobile.yourdomain.com [R=301]
4.RewriteCond %{HTTP_USER_AGENT} ^.BlackBerry.$
5.RewriteRule ^(.)$ http://mobile.yourdomain.com [R=301]
6.RewriteCond %{HTTP_USER_AGENT} ^.Palm.$
7.RewriteRule ^(.*)$ http://mobile.yourdomain.com [R=301]

or put something like this in a destination PHP page:

<?php

$mobile = “YOUR MOBILE SITE HERE”;
$text = $_SERVER['HTTP_USER_AGENT'];
$var[0] = ‘Mozilla/4.’;
$var[1] = ‘Mozilla/3.0′;
$var[2] = ‘AvantGo’;
$var[3] = ‘ProxiNet’;

...and so forth with more variable strings for various useragents then...

$result = count($var);

for ($i=0;$i<$result;$i++)
{
$ausg = stristr($text, $var[$i]);
if(strlen($ausg)>0)
{
header(“location: $mobile”);
echo ‘<BR>mobile device detected<BR>’;
break;
}

}
?>

Which solution is better? Or is there some other way?

Thanks!

any server-side solution (either .htaccess or php) is definitely the best solve.
