Dynamic PHP with WML

So I'm trying to build a dynamic site with WML/PHP and I having difficulty getting the PHP to show up in the WAP browser. I built a simple file and all I get on my phone (Treo 650) is a blank page.

Here's the code:

PHP Code:


		
			
<?xml version="1.0"?>

<?DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml"?>

<!-- -->

<?php 

// send wml headers

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

Header("Cache-Control: no-cache, must-revalidate");

Header("Pragma: no-cache"); 

?>

<wml>

<card id="card1" title="hello">

  <p>

  <?php

    echo 'Hello World!';

  ?> 

</p>

</card>

</wml>

I ran the code through w3schools validator and didn't receive any errors so my guess is that either the phone network (Sprint) WAP Gateway isn't working right OR the web server isn't recognizing the PHP--any ideas?

I'm betting it's your first two lines being interpreted as PHP since <? ?>is a quick start php tag. Echo those through php instead of trying to plain text display them outside of php. I actually just started really getting into WML today but the below header is working under firefox's WML extention. I haven't tested it on a phone yet.

PHP Code:


		
			
<?php 



header("content-type: text/vnd.wap.wml; charset=iso-8859-1");



echo "

<?xml version=\"1.0\"?>

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

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

";

?>

I don't know much about header info so I can't say if the extra ones you're using are correct or not.

Try changing your page to something like:

PHP Code:


		
			
<?php

<wml>

<card id="card1" title="hello">

  <p>

  <?php

    echo 'Hello World!';

  ?> 

</p>

</card>

</wml>

Maybe it isn't recognizing the DTD previously(?)

Since your device handles xhtml, why not write in that - it's a lot more versatile than WML.

Did you find an answer? If so could you post it as I have the same problem. The only way I can access a php file (saved without the headings) is through another file like the one below (saved as a .wml file)

Code:

<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN" "http://www.wapforum.org/DTD/wml13.dtd">

<wml>
  <card id="card1" title="customer">
    
    <p>
      Customer Details.<br/>
     

      <anchor>
        <go method="get" href="whateveryour fileis.php">
         
        </go>
        Submit Data
      </anchor>
    </p>
  </card>
</wml>

Try following code:

PHP Code:


		
			
<?php

// send wml headers

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

echo '<?xml version="1.0"?>

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

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

?>

<wml>

<card id="card1" title="hello">

  <p>

  <?php

            print "Hello World!";

  ?>

</p>

</card>

</wml>

It should work on your phone too. Most of the times the reason a WML page is not being rendered on the mobile device is that it is not in the standard form(Not Validated).

I am currently working on YaSUS! [ http://yasus.info ] which is the WAP enabled Short URL service. I was having similar problem in the starting, but later after proper validation I got it to work. You may see YaSUS! in action by navigating to http://snip.ws via your WAP enabled device.
