Hello, to detect BBerries and playbook table we’d be talking about something like that:
$blackberry = stripos($_SERVER['HTTP_USER_AGENT'],”blackberry”);
or is there any other thing required?
Many thanks for your solution!

I’ll look up the BlackBerry and Playbook user agents tomorrow and update the code to add support.

How can the code be modified to give the user the option to view the desktop version of the site if required from their mobile device?
Also on the conditional code section i.e.
}else if($iPad){
//were an iPad — do something here
How would add a redirect here to a m.mydomain.com address ?

You could simply add }else{ //do something } for a desktop version.
As for a redirect — php’s header function is your friend: header(‘Location: http://www.example.com/‘) — http://php.net/manual/en/function.header.php

Will the code above also resize it for the mobile device?

This code simply detects the most common mobile os’s. How you use it is up to you but it does not modify how a page displays. The only OS excluded is Windows Mobile — which I will add shortly.

Thanks for this, it might not work in every single case (Nokia Symbian and Windows Phone are missing, off the top of my head), and I need OS version checking for blackberrys as I plan on supporting the newer ones, but a very lightweight, usable script that gets the job done.

While it may not include support for all user agents out of the box it’s quite easily expanded. I’ll try and add in a few more user agents in the near future. Glad you found it useful.

Hi Chris,
I’ve stripped the details out of this script and left the focus on BlackBerry devices
only. I will be providing useful examples to other developers at the upcoming BlackBerry
Jam conference on August 23rd and this is a fine example of Agent detection for net
based content developers.
Thank you in advance for the useful code snippet :)
$BlackBerry = stripos($_SERVER['HTTP_USER_AGENT'],"BlackBerry");
$RimTablet= stripos($_SERVER['HTTP_USER_AGENT'],"RIM Tablet");
if($BlackBerry)
{
//we're a BlackBerry phone -- do something here
}
if($RimTablet)
{
//we're a RIM/BlackBerry Tablet -- do something here
}

I wanted to add a handy contribution for detecting tablet or mobile device
orientation in order to serve formatted content based on the orientation of the
device in either Portrait or Landscape mode:
/* Specific CSS can be applied to page elements if the user is holding their device in a given orientation. This is the CSS script. */
@media (orientation:portrait)
{
#isPortrait { display: block; }
#isLandscape { display: none; }
}
@media (orientation:landscape)
{
#isPortrait { display: none; }
#isLandscape { display: block; }
}
And these are the blocks you would place in your HTML page:
<div id=”isPortrait”>
//Show the content formatted for Portrait orientation between these Div tags.
</div>
<div id=”isLandscape”>
//Show the content formatted for Landscape orientation between these Div tags.
</div>

What if the switch in the middle of browsing? Does your method still work?
Thanks Anthony

I think if i leave it empty the on de index.php, the computer part, then it works.
Is there also a separate php part for only opera mini. It works different.
