Identity and Credential in different tables. How to login user? - zend-framework

Question

I'm using Zend Framework.
I save users information in two tables.
I have one table for his basic information and password, and in the other table I save his e-mails.
He can login with any e-mail.
My question is how should I extend Zend_Auth_Adapter_DbTable so that I can allow this?
I prefer not to use table views.
[edit]
I found a solution. What worked for me:
class My_Auth_Adapter_DbTable extends Zend_Auth_Adapter_DbTable
{
protected function _authenticateCreateSelect()
{
// build credential expression
if (empty($this->_credentialTreatment) || (strpos($this->_credentialTreatment, '?') === false)) {
$this->_credentialTreatment = '?';
}
$credentialExpression = new Zend_Db_Expr(
'(CASE WHEN ' .
$this->_zendDb->quoteInto(
$this->_zendDb->quoteIdentifier($this->_credentialColumn, true)
. ' = ' . $this->_credentialTreatment, $this->_credential
)
. ' THEN 1 ELSE 0 END) AS '
. $this->_zendDb->quoteIdentifier(
$this->_zendDb->foldCase('zend_auth_credential_match')
)
);
// get select
//$dbSelect = clone $this->getDbSelect();
$mdl = new My_Model_Db_Table_Users();
$dbSelect = $mdl->select();
$dbSelect = $dbSelect->setIntegrityCheck(false);
$dbSelect = $dbSelect->from(array('u' => $this->_tableName), array('*', $credentialExpression));
$dbSelect = $dbSelect->joinInner(array('ue' => 'users_emails'), 'ue.id_user = u.user_id', array('user_email'));
$dbSelect = $dbSelect->where('ue.' . $this->_zendDb->quoteIdentifier($this->_identityColumn, true) . ' = ?', $this->_identity);
return $dbSelect;
}
}

Answer 1

I explained what did it for me in the question.
But, to repeat, easiest for me was to change Zend_Auth_Adapter_DbTable::_authenticateCreateSelect().

Answer 2

There are a method named Zend_Auth_Adapter_DbTable::getDbSelect returns Zend_Db_Select object.
Call it and then you can join those two tables.
Hope this help.

Here's an alternate method.
Extend the Zend_Auth_Adapter_DbTable class.
class My_Auth_Adapter_DbTable extends Zend_Auth_Adapter_DbTable {
public function setDbSelect($select) {
$this->_dbSelect = $select;
return $this;
}
}
Create instance of your new adapter
$authAdapter = new My_Auth_Adapter_DbTable(
$this->dbTable->getAdapter()
, 'Users'
, 'Users.username'
, 'Users.password'
);
In your Application_Model_DbTable_Users class, create a method that returns the select object with the joined tables.
public function getSelectAuth() {
$select = $this
->select()
->setIntegrityCheck(false)
->from(array('SystemPeopleJoined' => $this->_name)
, array(
'id'
, 'person_id'
, 'system_role_id'
, 'created_on'
, 'expires_on'
)
)
->joinInner(
'People'
, 'People.id = SystemPeopleJoined.person_id'
, array(
'first_name' => 'first_name'
, 'last_name' => 'last_name'
, 'name' => "CONCAT_WS(' ', `People`.`first_name`, `People`.`last_name`)"
)
return $select;
}
Set the select object in your adapter
$select = $this->dbTable->getSelectAuth();
$authAdapter
->setDbSelect($select)
->setIdentity($params['username'])
->setCredential($params['password'])
->setCredentialTreatment("SHA1(?)")
;
