Passing data to PHP from a .xhtml file

I'm trying to send input data to a PHP file
from an .xhtml file

.xhtml file

Code:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" 
"http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Welcome to W@PSiTe</title>
</head>
<body>
<p>Welcome to W@PSiTe Mobile Service!<br/></p>
<form method="POST" action="loginwap.php">
<p>
Email :
<input type="text" name="email" />
Password :
<input type="password" name="password" />
<input type="submit" name="login_btn" value="Send Data" />
</p>
</form>
</body>
</html>

.php file

Code:

<?php  
// send wml headers 
header("Content-type: text/vnd.wap.wml");  
echo "<?xml version=\"1.0\"?>";  
echo "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\""  
   . " \"http://www.wapforum.org/DTD/wml_1.1.dtd\">"; 
?> 
if(isset($_POST['submit'])) {
	$pwd = md5($_POST['password']);
	$email = $_POST['username'];
	$sel_q = "select * from the_table where the_email = '$email' and the_pwd='$pwd' limit 1";
	$sel_r = mysql_query ($sel_r);
	$sel_c = mysql_num_rows($sel_r);
	if ($sel_c > 0) {
		echo "<p>OK!</p>";
	} else {
		echo "<p>NOT OK!</p>";
	}
} else {
	echo "<p>Wrong password!</p>";
}

I'm using "SmartPhone Emulator 6" as my emulator.
the .xhtml is ok but when sent to the PHP file it shows
"502 error" or "Error : 502 - No gateway Reply"

Am I doing it correctly? I'm really new to WAP and all things about wireless. Any input is very much appreciated.
thanks in advance.

Hi there, glad you found the wap forums at last

When you are sending wap headers, the outputed xhtml has to be correct or you will get nothing back....

Personally, for xhtml I send the headers as application/vnd.wap.xhtml+xml if the phone can handle it...

Anyhow, you should make sure you have the full page in the .xhtml file, you currently don't in your snippet at least...

php Code:

Original - php Code

<?php  
/* 
  send wml headers:
  try to send the same as your server is sending for .xhtml files 
*/
header("Content-type: text/vnd.wap.wml");  
echo '<?xml version="1.0"?>';
?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" 
"http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Processing login to W@PSiTe</title>
</head>
<body>  
<?php
/* sanatize the data before using mysql */
    $pwd = md5($_POST['password']);
    $email = mysql_real_escape_string($_POST['username']);
    $sel_q = "SELECT * FROM the_table 
            WHERE the_email = '$email' 
            AND the_pwd='$pwd' limit 1";
/* make sure the query is working as expected */
    $sel_r = mysql_query ($sel_r) or die('<p>'. mysql_error() .'</p>');
/* this bit isn't really needed, 
    or at least you can do it more effectively */
#
#   $sel_c = mysql_num_rows($sel_r);
#
 
    if (mysql_num_rows($sel_r) > 0) {
        echo "<p>OK!</p>";
    } else {
        echo "<p>NOT OK!</p>";
    }
} else {
    echo "<p>Wrong password!</p>";
}
/* debug, see what info is being passed */
echo '<div><pre>';
print_r($_POST);
echo '</pre></div>';
?>
</body>
</html>

hello:
haha, yeah...finally found the WAP forum.

thanks for the reply jabba.
i still get an error : "Reply Unknown"
here's my php code for now. (*for debugging)
.php file

Code:

<?php  
   header("Content-type: text/vnd.wap.wml, true");    
   echo '<?xml version="1.0" encoding="ISO-8859-1"?>'."\n";
?> 
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Processing login to W@PSiTe</title>
</head>
<body>  
<p>Welcome to W@PSiTe!</p>
<?php
echo '<div><pre>';print_r($_POST);
echo '</pre></div>';
?>
</body>
</html>

and my .xhtml file (all of it)

Code:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" 
"http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<form method="POST" action="loginwap.php">

<input type="text" name="email" />
Password :<br/>
<input type="password" name="password" />
<input type="submit" value="Send Data" name="login_btn" />
</p>
</form>
</body>
</html>
