Hi Hector,
I knew all the time there was something wrong in the addValidator function
but didn't know what. This works indeed better.
Now I have this function:
public function isValid($value, $context = null){
$date = new Zend_Date($value,'dd-MM-YYYY');
$this->_setValue($value);
$error = false;
//var_dump($this->_fieldsToCompare);
//exit;
foreach($this->_fieldsToCompare as $fieldName){
if(!isset($context[$fieldName])){
$error = true;
$this->_error(self::MSG_DATEBEFORE);
break;
}
$date2 = new Zend_Date($context[$fieldName],'dd-MM-YYYY');
$result = $date2->isLater($date);
echo $result;
}
return !$error;
}
but the $result dumps the whole object:
array(8) { ["evt_name"]=> string(9) "bladiebla" ["evt_description"]=>
string(0) "" ["adr_id"]=> string(1) "3" ["evt_startdate"]=> string(10)
"20-12-2009" ["evt_enddate"]=> string(10) "30-12-2009" ["evt_starttime"]=>
string(0) "" ["evt_endtime"]=> string(0) "" ["evt_amtpersons"]=> string(0)
"" }
But I only want a true or false.
