Error in WML code

Wow, not too much traffic in this forum... I still hope that someone can help me.

I run a php-script that produces a wml output but unfortunately not with the desired content. here is my 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">

<wml>

    <card id='card1' title='Shopping'>

        <p>

        <do type='accept'> 

            <go href='wap.php' method='post'>

                <postfield name='items' value='$Items'/>

            </go>

        </do>

        Shoppinglist:<br/>

        <select name='Items' multiple='true'>

            <option value='6'>Milk</option><br/>

            <option value='7'>Thuna fish</option><br/>

            <option value='8'>Salad</option><br/>

            <option value='9'>Meat (lots of!)</option><br/>

        </select>

        </p>

    </card>

</wml>

The wml-validator provided by w3schools.org reports an error in the line with the first option-tag. It says: "Element content invalid according to the DTD/scheme".

can anyone see the mistake I made?

cheers

what is your apache config (httpd.conf)?
is it only :

AddType text/vnd.wap.wml .wml
AddType application/vnd.wap.wmlc .wmlc
AddType text/vnd.wap.wmlscript .wmls
AddType application/vnd.wap.wmlscriptc .wmlsc
AddType image/vnd.wap.wbmp .wbmp

or you configure it with php :

AddType application/x-httpd-php .php3 .php .phtml .wml

?

if you choose the first one, i think it would work well according to your script. But if fail, I suggest you choose the 2nd choice and give this extra syntax into your first line of the script.

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

PS. sorry for my bad english
i hope you understand.

Heyup ! I tried this out on my system, and used the PyWeb emulator to check it. It objected to the <br/> at the end of each option line. The other thing I had problems with was the header, and this has been the case for quite a while now. It seems to be very picky about format and spacing, so in the end I constructed a PHP header which I know include in all my WAP/WML pages. Also, i don't know if it's significant, but I changed single quotes to double quotes.

The code below shows the final result, which seems to work.

Code:

<?php 
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.xml\">"; 
?>
<wml>
    <card id="card1" title="Shopping">
        <p>
        <do type="accept"> 
            <go href="wap.php" method="post">
                <postfield name="items" value="$Items"/>
            </go>
        </do>
        Shoppinglist:<br/>
        <select name="Items" multiple="true">
            <option value="5">Veg</option>
            <option value="6">Milk</option>
            <option value="7">Thuna fish</option>
            <option value="8">Salad</option>
            <option value="9">Meat (lots of!)</option>
        </select>
        </p>
    </card>
</wml>

inijoey was right about the WML Apache config - mine looks like this..

Code:

AddType application/x-httpd-php .php .php3 .php4 .htm .html .wml
AddType text/vnd.wap.wmlscript .wmls
AddType image/vnd.wap.wbmp .wbmp

Hope this helps..

PS .. I added a veg option as number 5 ..
