[Chameleon] problem accessing HTML Hidden Variable

[Jan Jansen]

Hi Jacob,

disregard my last message, iIworked it out already. I made a mistake: I had 2 Hidden's with the same name in my template, then chameleon doesn't recognize any of them... (a bit strange, but problem solved :)

Best regards, Jan

  Hi Jan,

  This line:

  $szValue = " <INPUT TYPE=HIDDEN NAME=$szVariable VALUE=\"\">";

  should be

  $szValue = " <INPUT TYPE=HIDDEN NAME='".$szVariable."' VALUE=\"\">";

  You actually included the variable reference as part of the string. So $szVariable would not have been picked up as a variable name. Probably if you check the source code of the page, you could see it being written out as $szVariable. I also put some quotes.

  regards,

  Jacob

  Hello list,

  I have a problem accessing an HTML hidden variable in my wigdet. Please can anyone tell me what I am missing here?

  I include the custom Hidden variable as follows (this all works fine):


   function GetHTMLHiddenVariables()
      {
        // parent::GetHTMLHiddenVariables();

          $szVariable = "CUR_PPC";
          $szValue = " <INPUT TYPE=HIDDEN NAME=$szVariable VALUE=\"\">";
          $aReturn[$szVariable] = $szValue;
          return $aReturn;
      }

  *****

  a javascript function on my template fills the hidden var with a value (this all works fine):

  ******

   /**
       * get the javascript functions for this widget
       */
      function GetJavascriptFunctions()
      {
          $aReturn = array();
          $szJsFunctionName = "zoom24ppc";
          $szFunction = <<<EOT
  /**
   * {$szJsFunctionName}
   * called when the ppc value is set.
   */
  function {$szJsFunctionName}(obj)
  {
      
   {$this->mszHTMLForm}.CUR_PPC.value = obj; 
   //alert({$this->mszHTMLForm}.CUR_PPC.value);
     {$this->mszHTMLForm}.submit();
          
      return;
  }
  EOT;
          $aReturn[$szJsFunctionName] = $szFunction;

          return $aReturn;
      }

  ******

  But when I try to access the variable in ParseUrl function, it fails to read out the value:

  ******
    function ParseURL()
     {
      // Check if HIDDEN input is set 

          $szVariable = "CUR_PPC";
         if ($this->isVarSet($szVariable))
     {
              $CURPPC = $this->getVar( "CUR_PPC" );

  etc, etc.. What am I forgetting here? Any help would be highly appreciated

  regards, 

  Jan
