WAP and PHP - doesn't like the header('Content-type: text/vnd.wap.wml\n\n');

Hello,

I've been trying to get this working, but no luck. My phone is a Samsung m500

I've coded a page on my server to check to see if the header is for text/vnd.wap.wml, and if so, attempt to create the wml page.

If I include the php code:
header('Content-type: text/vnd.wap.wml\n\n');

my phone browser returns a msg:
The requested page cannot be displayed.

If I exclude the header line above, it displays the page, however, the <anchor> tag is not selectable.

If anyone can suggest a fix, or tell me what's wrong, I'd appreciate it.

You can view the page on your phone at: (URL address blocked: See forum rules)

This is the code I've setup for the wml:

PHP Code:


		
			
<?php

    session_start();



$headers=apache_request_headers();



$pos = strpos($headers['Accept'], "vnd.wap.wml");

if ($pos === false) {

    // stay on this page

} else {

    header('Content-type: text/vnd.wap.wml\n\n');

    echo '<?xml version="1.0"?'.'>';

?>

<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN" "(URL address blocked: See forum rules)">



<wml>

  <card id="card1" title="User Login">

    <onevent type="onenterforward">

      <refresh>

        <setvar name="my_temp_id" value="123456"/>

      </refresh>

    </onevent>

    <p>

      Bingo Lotto Fun!<br/><br/>

      User Id: <input type="text" name="varname" maxlength="10" emptyok="false"/><br/>

      Password: <input type="password" name="varpswd" maxlength="6" emptyok="false"/><br/>



      <anchor>Login

        <go method="get" href="wapprocessing.php">

          <postfield name="clientname" value="$(varname)"/>

          <postfield name="clientpswd" value="$(varpswd)"/>

        </go>

      </anchor>

    </p>

  </card>

</wml>



<?php

    die;

}



//... regular html code here

Thanks,

Robert

PHP Code:


		
			
 header('Content-type: text/vnd.wap.wml\n\n');

This will just add the characters, not create new lines -
though I don't know why you are trying to create new line.

If you really want to add new lines to the header, then you must use "double quotes" -

PHP Code:


		
			
<?php

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

You may want to add , true to that line...

PHP Code:


		
			
<?php

header('Content-type: text/vnd.wap.wml, TRUE');

see strings for more.

And make sure you validate your WML. See the WAP Resources thread for a tools list.

Welcome to Dev Shed, enjoy your stay ...

Thank you jabba_29

,

I had noticed the ' vs " issue with my \n characters, and had fixed that.

Once I added the ,TRUE to the header() stmt, that resolved the issue.

I did use the link for the validators for some other issues, I appreciate the links.

I'm not doing this any more

Grateful for your help.

Robert
