Brandon, any chance you could share with us where you found the mobile detect PHP class?

Not sure what Brandon used, but you can have a look at CodeIgniter’s User Agent class.

Ours is a custom PHP script loosely based on the tutorials below:

and using the WURFL database (http://wurfl.sourceforge.net/)

How does EE determine a mobile user? Is it using a database such as WURFL or do you simply look for a certain set of strings in the user agent?

EE doesn’t have any mechanism for identifying mobile users - CodeIgniter’s code is open, though, so you can download and take a look.  It’s pretty simple - we actually maintain our own list based on known user agents.  It’s lightweight as you don’t need a full user agent string to be able to identify the platform.

Do not use the code you used above… I’ve already tried to tackle that to no avail.  This is what I did after reading hte forums and it’s working AWESOMELY!

Create another template group called mobile and duplicate your real site… then strip out the html as you want it to look for mobile.  Finally, stick this code in your index template and enable php (I’ve updated it for iphone and LG Dare):

This should work:

I am trying to do something like this,

{if ...}
   some stuff
{if:else}
   header("location: ".$url);exit;
{/if}

the site seems to be redirecting regardless of the if condition (redirects even when the condition is true)

Any idea what I am doing wrong or how can I achieve such functionality!

Actually that code above works for me perfectly every time.  Although I have noticed that just yesterday when I upgraded to IE8 that it redirects to the mobile version.  I had to fix that for IE8 Beta.  The user agent string for IE8 is Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0)

But I removed Mozilla/4.0 and that fixed the IE8Beta, but IE8 final release is still redirecting.  That will take some more looking into.

Thanks jeramiah for the time you take to read my post and comment on it.

For now (until we can find a better solution) i embeded the whole page. But still looking for a solution to have the task done in the proper way.

No problem, I’ll be in and out this weekend but I’ll focus on it this upcoming week.  Thanks.

zedEye why are you mixing EE conditionals and PHP?  I’d use one or the other, and you’ll find that your expectations will be easily matched.  In your specific case, PHP is parsed before advanced EE-syntax conditionals can be evaluated, so the header() function will always execute.

I tried {redirect} but it didn’t work. That’s why the php code. Is there anything else in EE that can be used to do the job?

You could either use PHP for your conditionals, so that you’re not mixing two different types of control structures.  Or, use the redirect variable.  Just saying “it didn’t work” without providing full details of what you tried and how it failed won’t help you towards a solution, though.  Check first that you are using a version of ExpressionEngine that supports this feature.  If you are and it’s still not working, I’d recommend posting in the technical support forums for assistance.

Just get rid of this line:

$var[66] = 'NEC';

IE 8 will not redirect to the mobile version after that.
