[jQuery] radio buttons and php

[lukas]

I don't get this to work. Somehow the PHP code is ignored within the
radio input forms. Can I change PHP variables within the code and work
with them in the according #div? Does anybody have a hint? Thank you!

jQuery:

        $("#input-l:input:radio,#input-c:input:radio").click(function(){

          if ($(this).is(":checked")) {
             $("#div").show();
           }
         else if($(this).not(":checked")) {
            $("#div").hide();
           }
        });

radio buttons:

<input type="radio" id="input-c" name="user-type" value="1" <?php some
code ?>>
<input type="radio" id="input-l" name="user-type" value="2" <?php some
code ?>>
