The reason I made my own unique check is that my version of 1.2 has a bug in isUnique and always returns 0 because it sets the field equal to the value.

Your way of validation seems to take a database call for each unique. If isUnique now works in 1.2 my ideal way to use it is:

var $validate = array( // validate our username and email
‘username’ => array(’rule’ => array(’alphaNumeric’)),
‘email’ => array(’rule’ => array(’email’))
);
function beforeSave() {
$check = array(’username’,'email’); // username and email are unique
return $this->isUnique($check); // isUnique returns #fields matching
}

my validation looks like:

var $validate = array(’email’ => array(’not_unique’ => array(’rule’ => array(’validateUnique’, ‘field’ => ‘email’)),’not_valid’ => VALID_EMAIL, ‘not_empty’ => VALID_NOT_EMPTY));

function validateUnique($value, $field)
{
$valid = false;
$valid = $this->isUnique(array($field => $value));
return $valid;
}

$this->model->isUnique(’value’);
