I am trying to validate multiple checkboxes of a HABTM table. I managed to
validate the values but cannot get a message to display. I have my own
compare values in db against submitted data to validate but no message
appears....
I then see in the cookbook
var $validate = array(
'function' => array(
'allowedChoice' => array(
'rule' => array('inList', array('Foo', 'Bar')),
'message' => 'Enter either Foo or Bar.'
)
)
);
and
var $validate = array(
'multiple' => array(
'rule' => array('multiple', array('in' => array('foo', 'bar'), 'min'
=> 1, 'max' => 3)),
'message' => 'Please select one, two or three options'
)
);
Would either of these work for validating multiple checkboxes?
And how do I get the values of the fields when they say
'rule' => array('inList', array('Foo', 'Bar')),
Or
'rule' => array('multiple', array('in' => array('foo', 'bar'), 'min' => 1,
'max' => 3)),
Thanks,
Dave
