You can use your own validation functions in your model for this:
class Article extends AppModel {
var $validate = array(
"name"=>array(
"rule"=>"myRule",
"message"=>"you failed myRule!"
)
);
function myRule($data) {
// $data contains the value of 'name'
// $this->data contains the rest of the submitted data
// return true if validation passed otherwise
// return false
}
}
see http://book.cakephp.org/view/150/Custom-Validation-Rules for more
concrete examples
