[TYPO3-project-formidable] Multiple values from LISTBOX

[Jerome Schneider]

Hello, the code is :

if($this->_isMultiple()) {
   if(is_array($sValue)) {
     if(in_array($value, $sValue)) {
       $sSelected = " selected=\"selected\" ";
     }
   }
} else {
   if($aItem["value"] == $sValue) {
     $sSelected = " selected=\"selected\" ";
   }
}


Is it correct ? I heard that selected="selected" is the xhtml way of 
doing things ?



Thanks,
Jerome Schneider
