And as i thought I am already in trouble:
See comments in the code below.
public function isValid($value, $context = null){
$date = new Zend_Date($value,'dd-MM-YYYY');
$this->_setValue($value);
$error = false;
var_dump($this->_fieldsToCompare);
//this dump shows me the acutal text box in the form with the date in
it and the label and so on.
foreach($this->_fieldsToCompare as $fieldName){
echo $context[$fieldName];
//this echo is empty.
if(!isset($context[$fieldName]) || $value !==
$context[$fieldName]){
$error = true;
$this->_error(self::MSG_DATEBEFORE);
break;
}
}
return !$error;
}
What i need is the value of the startDate which i have given in my
addValidator function
:$evtEndDate->addValidator('CompareDates',false,array<http://www.php.net/array>
($evtStartDate)); and then convert it to a date object in order to be able
to compate dates with the isEarlier function.
How can i do this?
