WAP WML, and PHP

Ok. First off I'd like to call myself above intermediate with PHP and MySQL (html css and all of that is implied). And I have encountered a task, where I have a dynamic version of a single page, that I need to also have a simple WAP version (an old Grayscale mobile device), will perform the same fetches from a MySQL database with PHP, and I want it to display to the WAP browser (via wml?). My problem is I am following this tutorial

http://www.developer.com/lang/php/article.php/10941_1449061_1

page 1 and 2 go smoothly (I'm using PHP 4.3.x MySQL 5.xx and IIS 6.0 i believe). I added the php.exe to the wml extension as per instructed on page 2 of that tutorial. I then make a test.wml with

PHP Code:


		
			
<?php



header("Content-type: text/vnd.wap.wml");  



print "<?xml version=\"1.0\"?>\n";  

print "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\""  

   . " \"http://www.wapforum.org/DTD/wml_1.1.xml\">\n"; 

   

print "<wml>\n";

print "<card>\n";

print "<p>Hello world</p>\n";

print "</card>\n";

print "</wml>\n";



?>

That works and I can see it.

However I don't want it to be http://www.mysite.com/test.wml

I want to have it http://www.mysite.com

which ofcourse loats index.php
and within index.php it could have

PHP Code:


		
			
 $usr_agent = strtolower($_SERVER['HTTP_USER_AGENT']);

    

if((strpos($usr_agent,"blackberry") === true){

//They need wml for these WAP devices



} else{

//Its a pc

}

But whenever i try to go to index.php through the wap browser on the mobile device, I get Error 406, Not Acceptable "Page not loaded because browser doesn't support"

Any Ideas/Help PLEASE.

Try checking the strpos condition as !== FALSE.

Additionally, does blackberry support that old a version of wap?
I would go for XHTML MP personally.

Of course, if your domain loads index.php by default,
why not do something like

PHP Code:


		
			
<?php



if((strpos($usr_agent,"blackberry") !== FALSE){ 

// redirect

// exit();

}

// show default

This would be the wrong way according to dotmobi though.
If it is not a mobile you should redirect, not the other way around.

But anyway, hope that gives you a bit of an idea.

So then by default I should have my page go to index.wml?

and if the browser isn't mobile, redirect it to index.php?

Because I have the access to change the default page to index.wml instead of index.php. I'm just wondering how would I write it in the wml page to detect if its mobile or not... same way as I did in the PHP?

Your wml page doesn't need to be .wml. It can still be .php.

wml is just mark up language - it cannot detect what device is browsing the page.

so have my main page index.php,

and within that use WML, and if the device is a Desktop, I forward it to lets say desktop.php, otherwise I stay on index.php where my WML/WAP is?

Yes.

take a look at the dotmobi recommendations for device detection and redirection -
they may help you a bit.

I have written a Drupal module that renders content according to device.
Andymoo has done similar with Wordpress.

Check out the WAP Resources for links..
