Here's a stripped down example of how I do it:
app_model.php
class AppModel extends Model {
...
function isUniqueMulti($data, $fields) {
if (!is_array($fields)) {
$fields = array($fields);
}
foreach ($fields as $key) {
$tmp[$key] = $this->data[$this->name][$key];
}
return $this->isUnique($tmp, FALSE);
}
}
some_model.php
class SomeModel extends AppModel {
var $validate = array(
'field1' => array(
'rule' => array('isUniqueMulti', array('field1', 'field2')),
'required' => TRUE,
'message' => 'Error Message',
),
'field2' => array(
'rule' => 'notEmpty',
'required' => TRUE,
'message' => 'Error Message',
),
);
}
