Hi,
I'm developing my first web-application and I'm still RTFM (Reading
The Fabulous Manuals), but I need a little help with a form
validation.
For this application I'm using the Admin Generator.
The form contains 5 target fields: T1, T2, T3, T4, T5; every target
must be greater than the previous: T1 < T2 < T3 < T4 < T5.
But only T1 is required while the other targets can be empty.
If a target is empty all the next ones must be empty.
So:
T1= 100, T2= 200, T3=empty, T4=empty, T5=empty is valid,
but:
T1=100, T2=empty, T3=200, T4=empty, T5=empty is NOT valid.
I'm putting some code in lib/form/<model>Form.class.php:
class ListinoForm extends BaseListinoForm
{
public function configure()
{
$this->validatorSchema->setPostValidator(new sfValidatorAnd(array
(new sfValidatorSchemaCompare('T1',
sfValidatorSchemaCompare::LESS_THAN, 'T2'))));
}
}
but I don't know how to test if a field is empty and I'm afraid that
the resulting instruction will be very hard to read.
Any hint?
TIA
Stefano
