Question

I have my controller, my function to insert into the database, and the form.
I just want to insert the user in the database if he enter the email is not already registered in the database.

My controller:

$nome       = $this->_request->getParam('nome');
$senha      = $this->_request->getParam('senha');
$confirmar  = $this->_request->getParam('confirmar');
$email      = $this->_request->getParam('email');
$usuarios = new Application_Model_DbTable_Usuarios();
$usuarios->addUsuario($nome, $senha, $email);

My DbTable_Usuario class that contains my function that inserts the user in the database

public function addUsuario($nome, $senha, $email) {
    $data = array(
        'id'    =>  'NULL',
        'nome'  =>  $nome,
        'senha' =>  $senha,
        'email' =>  $email,
        'nivel' =>  '0'
    );
    $this->insert($data);
}

And my zend_form

$email = new Zend_Form_Element_Text('email');
    $email->setLabel('Email:')
          ->setRequired(true)
          ->addValidator('EmailAddress')
          ->addValidator('NotEmpty');

I have some way to add something to the form it checks if the mail entered already exists in the database? If it exists, it displays the message, and if not, insert it in the bank.

Add a Zend_Validate_Db_NoRecordExists validator to the email field.
