Hi all,
I've the following situation: In a form i put a multicheckbox element with a
certain number of elements say n. I'want the user select a number of
elements between x and y with 0 <= x < y <= n
For this i've just tried to write my custom validator extending the
Zend_Validate_Between class, overriding its isValid method with something
similar to this:
public function isValid($value) {
return parent::isValid(count($value));
}
because I tought that $value is an array, but it's not the case, my
validator will be called once per selected checkbox with scalar values. So
I've tried a different approach:
protected $count = 0;
public function isValid($value) {
if (++$this->count > $this->_max) {
return false;
}
return true;
}
I'm unsure about correctness, it breaks if the same validator instance will
be attached to more than one multi element, and clearly it works only for
the max, but not for the min.
Any suggestion?
