Hey, I think there's no problem with your approach:
'dob' => array(
'required' => true,
'allowEmpty' => false,
'rule' => 'date',
'message' => 'Some message here.'
)
There might be something wrong on the view, or did you do validation
on controller ?
In case you're need some conversion, you could use custom
validation[1]. Here's an example that use custom validation
that trying to validate dob to disallow age under 18:
'dob' => array(
'required' => array(
'required' => true,
'allowEmpty' => false,
'rule' => 'date',
'message' => 'Required'
),
'valid' => array(
'rule' => array('vDob', 18),
'message' => 'Must be above 18 years old'
)
)
function vDob($field, $maxAge) {
$studentYear = date('Y', strtotime($field['dob']));
$currentYear = date('Y');
if ( ($currentYear-$studentYear) < $maxAge ) {
return true;
} else {
return false;
}
return true;
}
Custom validation rule must returns boolean value.
