Assuming you are using 1.2
I have created this snippet in the model. Could be but in app_model if
it is required.
//checks to see if the given fieldname is unique with the model
function checkUnique($data, $fieldName) {
$valid = false;
$this->recursive = -1;
if(isset($fieldName) && $this->hasField($fieldName))
{
$valid = $this->isUnique(array($fieldName => $data));
}
return $valid;
}
the validate array within the model can be as follows. Notice the
multiple validation rules for email.
The on=> 'create' only validates this rule on an insert into the
database.
The message will automagically appear in the view. No need for the
tagErrorMsg. just ensure you are using the html Helper.
var $validate = array(
//password must be at least 6 characters and consist of only
alphanumeric
'password' => array(
'rule' => array('custom',
'/[a-z0-9]{6,}$/i'),
'message' => 'Only letters and numbers,
min 6 characters'
),
//email address must exist and must be a unique value
within the
Customers.email field.
'email' => array(
'email_valid' => array(
'rule' => 'email',
'message' => 'Valid email address required',
),
'email_unique' => array(
'rule' => array('checkUnique', 'email'),
'message' => 'Email address already used.',
'on' => 'create'
)
),//end email
