Well its just typical that after researching for ages and eventually
resigning myself to mailing the list I find an answer. Using a callback post
validator. So for anyone else that has a similar issue here is the way to
get it done:
First, set the post validator as such:
$this->validatorSchema->setPostValidator(
new sfValidatorCallback(array('callback'=>array($this,
'checkDates'))));
What this does is tell the form to pass validation of the content of the
form values to a function called checkDates. Then create the new function
inside your forms class as such:
public function checkDates($validator, $values)
{
if (empty($values['end_date']))
{
return $values;
}
else if (strtotime($values['start_date']) >
strtotime($values['end_date']))
{
throw new sfValidatorError($validator, 'NEW VALIDATOR!! The start date
needs to be before the end date');
}
return $values;
}
You can obviously do whatever you need to validate the contents of your own
validator but as you can see here I first check to see if end_date is empty.
If so, alls good and continue (remember that start_date is validated to have
a date in it before the post validator is called so I don't need to do it
again). If, however, my end_date is not empty and start_date is greater than
end_date, throw exception error for the form class to handle. Otherwise,
just return.
A good example I found of the callback post validator can be found here:
