Zend Validate UniqueField

Gebruik:

Je [u]moet[/u] een model maken met minimaal het volgende:

[code]

<?php
class Users extends Zend_Db_Table
{
  protected $_name = 'users';
  protected $_primary = 'user_id';
}
[/code]

($_primary is natuurlijk niet nodig maar ik gebruik ID niet als mijn primary key)

het form element:
[code]
<?php
$this->addElement('text', 'name', array(
  'decorators' => $this->_standardElementDecorator,
  'label' => 'Desired Username:',
  'Validators' => array(
    array('StringLength', false, array(5,20)),
    array('UniqueField', false, array('users', 'username')),
  ),
  'required' => true
));
[/code]

specifiek deze regel:
[code]array('UniqueField', false, array('users', 'username'))[/code]

UniqueField = naam van validator.
users = naam van model
username = naam van veld

en de validator:
ps. Ja ik heb hem gewoon in mijn Zend/Validate folder staan :)
[code]

        $result = $table->fetchAll($table->select()->where("$this->_fieldName = '$value'"))->toArray(); 
		
        // Check to see if we got any results 
        if (count($result) == 0) { 
            return true; 
        } 
 	
        $this->_error(self::NOT_UNIQUE); 
        return false;

Ik hoop dat iemand hier iets aan heeft.
