  So here is the problem. I have an admin interface where I would like it to be possible for the admin to add another text field to a group. So imagine there are 4 text fields, and I want to add another. A model of what I would like to do is in the extmenu interface when you choose Create new menu item. However, I am having some trouble seeing how this works. It appears to be calling a javascript routine, and in fact, when you switch javascript off, it no longer works. I need to have my function work with javascript on or off.
  
  In my situation, the admin is creating a multiple choice question, and in the default case there are 4 choices. However, they may want 2,3, or 5. How can I code it so that the interface changes. I am using pnform to do this. I have made several attempts at this, but it always seems to get hung up when I try to refresh the interface. Here is the code I am using.
  

  Code

  function quickcheck_admin_newMCQuest($args) {
      $num_mc_choices = $arg['num_mc_choices'];
      if(!isset($num_mc_choices)){
          $num_mc_choices = 5;
      }
      // Security check - important to do this as early as possible to avoid
      // potential security holes or just too much wasted processing
      if (!SecurityUtil::checkPermission('quickcheck::', '::', ACCESS_ADD)) {
          return DataUtil::formatForDisplayHTML(_MODULENOAUTH);
      }
  
      // Create output object - this object will store all of our output so that
      // we can return it easily when required
      $pnForm =FormUtil::newpnForm('Quickcheck');
      //a test array for now
      $pnForm->assign('num_mc_choices', $num_mc_choices);
      // Return the output that has been generated by this function
      return $pnForm->pnFormExecute('quickcheck_admin_new_MC_question.htm', new quickcheck_admin_newMCQuestionHandler);
  }
  
  
  /**
   * quickcheck_admin_newTextQuestionHandler

  class quickcheck_admin_newMCQuestionHandler {
  
      function initialize(&$render) {
  
  
          // load the categories system
         // [... snip ...]
  
          return true;
      }
  
      function handleCommand(&$render, &$args) {
  
          if ($args['commandName'] == 'update') {
              if (!$render->pnFormIsValid())
                  return false;
  
              $data = $render->pnFormGetValues();
              //set the type of question
              $data['q_type'] = _QUICKCHECK_MULTIPLECHOICE_TYPE;
              //grab the various MC options
             
                if(!pnModAPIFunc('quickcheck', 'admin', 'createquestion', $data)) {
                  return LogUtil::registerError (_CREATEFAILED);
              }
              //if we have gotten here, we were successful
              SessionUtil::setVar('statusmsg', '_QUICKCHECK_NEW_QUEST_CREATED');
              pnRedirect(pnModURL('quickcheck', 'admin', 'view'));
          }
          if( $args['commandName'] == 'cancel') {
              pnRedirect(pnModURL('quickcheck', 'admin', 'view'));
          }
          if( $args['commandName'] == 'removeChoice') {
              //find the number of current choices
              $choices = FormUtil::getPassedValue('q_text');
              $a_size = count($choices);
              if($a_size > 2){
                  $value = array_pop($choices);
              }
              $a_size = count($choices);
              //pnRedirect(pnModURL('quickcheck', 'admin', 'newMCQuest', array('num_mc_quests' => $a_size)));
  
          }
          return true;
      }
  }

  
  
  Any help with this is appreciated.If you look at removeChoice, this is the code that I was hoping would do the trick. I can grab the variable I need (q_text) and change its size. My question is, how do I get this to update?
