I'm trying to find out if you can use this against an array, where if
it's equal to any option in the array it validates. I don't see
anything on this, and it doesn't seem to work when I try it. Is there
any other cake way to check if it's equal to an item in an array?
Here is what I have in my model:
'field' => array(
'notempty' => array(
'rule' => array('equalTo', array('option1', 'option2',
'option3')),
'message' => 'Please select an option'
)
)
where 'field' is a select field that doesn't exist in the database.
