Zend Framework: How to check an additional column while using DbTable Auth Adapter? - zend-framework

Question

Currently, I'm getting a regular DbTable Auth Adapter:
protected function _getAuthAdapter($formData)
{
$dbAdapter = Zend_Db_Table::getDefaultAdapter();
$authAdapter = new Zend_Auth_Adapter_DbTable($dbAdapter);
$authAdapter->setTableName('users')
->setIdentityColumn('username')
->setCredentialColumn('password');
$authAdapter->setIdentity($formData['username']);
$authAdapter->setCredential(md5($formData['password']));
return $authAdapter;
}
But I want to check an additional column in the database (IsActive for example). I don't know if this can be done with the adapter. How can this be done?

Answer 1

I have a similar situation, and I extended the Zend_Auth_Adapter_DbTable to satisfy my needs:
class My_Auth_Adapter_DbTable extends Zend_Auth_Adapter_DbTable
{
protected $_customerIdColumn = 'customer_id';
protected $_customerId = false;
public function setCustomerId($id) {
$this->_customerId = $id;
return $this;
}
public function getCustomerId() {
return ($this->_customerId !== false) ? $this->_customerId : '';
}
public function _authenticateCreateSelect() {
$dbSelect = parent::_authenticateCreateSelect();
$dbSelect->where($this->_zendDb->quoteIdentifier($this->_customerIdColumn, true) . ' = ?',
$this->getCustomerId());
return $dbSelect;
}
}
I then use it like this:
public function getAuthAdapter(array $params)
{
$authAdapter = new My_Auth_Adapter_DbTable(
$params['db_adapter'],
'users',
'username',
'password',
'? AND active = 1'
);
$authAdapter->setIdentity($params['username'])
->setCustomerId($params['customer_id'])
->setCredential($params['password']);
return $authAdapter;
}

I use two columns for my Zend_Auth_Adapter_DbTable, and it looks like this:
$authAdapter = new Zend_Auth_Adapter_DbTable(
Zend_Registry::get('database'),
"user",
"username",
"password_hash", // column 1
"MD5( CONCAT(?,password_salt) )" // column 2
);
When authenticating, the SQL ends up looking like this:
SELECT `user`.*,
(CASE WHEN `password_hash` = MD5( CONCAT('password entered',password_salt) )
THEN 1 ELSE 0 END) AS `zend_auth_credential_match`
FROM `user` WHERE (`username` = 'username entered')
So, that checks an additional column, password_salt, and for me it works well. I don't know if that helps you, as I don't know what you're trying to do.

Answer 3

The included Auth Adapater Zend_Auth_Adapter_DbTable does not allow you to check an additional column. You could extend the Zend_Auth_Adapter_DbTable class and add another column. You will have to add a member variable for the value of new field $_otherFieldValue and a public function setMemberField($value). Finally, you would have to override:
protected function _authenticateCreateSelect()
Hope that helps.

I know this question may be already solved but you can also solve this without needing to extend the class, use the getDbSelect() method and add the where clause to it:
$authAdapter = new Zend_Auth_Adapter_DbTable(Model_Users::getDefaultAdapter());
$authAdapter->setTableName('users');
$authAdapter->setIdentityColumn('email');
$authAdapter->setCredentialColumn('password')->setCredentialTreatment('md5(?)');
$authAdapter->setIdentity($email);
$authAdapter->setCredential($password);
$authAdapter->getDbSelect()->where('active = 1');
