I am attempting to make an authentication plugin. JUser::getInstance() takes one input, and it is supposed to be the id. Is there any way to get an instance of a User using some other indentifier? such as username, email etc.
Probably there isnt any such method. But yes if you are sure that username or email are unique then you can modify your file user.php in libraries/joomla/user/ and add a method there.
getInstanceByEmail($email)
{
$query = "select id from jos_users where email=".email;
// use the code to get the id;
return getInstance($id);
} // this is just a sample code of how it can be achieved
Since Joomla's own authentication is done by checking the user's username (and password of course), it has to be unique. And yes you can do something like what #Rixius suggested.
Here's my version:
// Get a database object
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('id, password');
$query->from('#__users');
$query->where('username=' . $db->Quote($credentials['username']));
$db->setQuery($query);
$result = $db->loadObject();
$user = JFactory::getUser();
if ($result)
{
$user = JUser::getInstance($result->id);
}

I've included yahoo API to read user's yahoo contacts. However it's not fetching any data.
Please have a look at my code:
session_start();
include_once 'config.php'; //This file contains consumer key & all data
require_once ('Yahoo.inc'); //This is a standard Yahoo file, just copied it
$session = YahooSession::requireSession($consumer_key,$consumer_secret,$app_id);
if (is_object($session))
{
$user = $session->getSessionedUser(); //This is NOT NULL
$profile = $user->getProfile(); //This is NULL
$name = $profile->givenNme;
$guid = $profile->guid;
$contacts=$user->getContacts()->contacts; //This is NULL
if($contacts==NULL){
echo "No contacts";
}
}
Somehow getProfile() & getContacts() are not working at all, anyone can help spot the mistake?
Please check this thread: yahoo oauth $user->getProfile(); returns null. It solves the problem. You need to switch over to the new API. Otherwise, you may experience this kind of problems.
I'm 11 and I'm making a chat site for me and my friends. I'm using MYSQLi to handle the database things, and I'm kinda new to it. I always used normal mysql.
Oh! And if you can share a link to a mysqli tutorial, it would be great :)
Well here's my config file
<?PHP
define("HOST", "localhost"); define("USER", "root"); define("PASSWORD", "****"); define("DATABASE", "secure_login");
$mysqli = new mysqli(HOST, USER, PASSWORD, DATABASE);
?>
The database is secure_login, then I have a table called members, and then a column named email in that table.
I included this to a file (register.php) where I have to check if the email exists or not. And if it exists, redirect to home.
If you guys can help me it would be cool!!! I hope to finish this soon :)
I'd start with reading the MySQLi documentation at http://php.net/manual/en/book.mysqli.php, in specific the methods related to the class. If you are in need of a tutorial I would suggest to search on Google, there are loads of tutorials on the web.
As for your question, something like this should work:
$query = "SELECT email FROM members WHERE USER = ? AND PASS = ?";
if ($stmt = $mysqli->prepare($query)){
// Bind the parameters, these are the ?'s in the query.
$stmt->bind_param("ss", $username, sha1($password));
// Execute the statement
if($stmt->execute()){
// get the results from the executed query
$stmt->store_result();
$email_res= "";
// This stores the value of the emailaddres inside $email_res
$stmt->bind_result($email_res);
$stmt->fetch();
// There is a result
if ($stmt->num_rows == 1){
// Validate the emailadres here, check the PHP function filter_var()
}
else {
// Not a valid email
}
}
else {
printf("Execute error: %s", $stmt->error);
}
}
else {
printf("Prepared Statement Error: %s\n", $mysqli->error);
}
}
I hope this helps
In my model, "Users", I have the following authorization after validating the username/password
$db = Zend_Db_Table::getDefaultAdapter();
$authAdapter = new Zend_Auth_Adapter_DbTable($db,'users','username','password');
$authAdapter->setIdentity($username);
$authAdapter->setCredential(md5($password));
$auth_result = $authAdapter->authenticate();
if( $auth_result->isValid() )
{
$auth = Zend_Auth::getInstance();
$storage = $auth->getStorage();
$storage->write($authAdapter->getResultRowObject(array('id','username')));
return 'logged_in';
}
return 'auth_failed';
it keeps returning 'auth_failed'. I had the code running on a localhost, and everything works fine, but when I upload it online, it fails to authorize the user. What is going on?
Thanks
I can't tell what's wrong without checkin the logs, so perhaps you might want to use the method I use for storing auth data. Basically you validate manually and set the storageThis doesn't solve the problem, but its impossible to do so without accessing your code.
function login($userNameSupplied,$passwordSupplied){
$table= new Application_Model_Dbtable_Users();//Or Whatever Table you're using
$row=$table->fetchRow($table->select()->where('username=?',$userNameSupplied)->where('password=?',md5($passwordSupplied));
if($row){
Zend_Auth::getInstance()->getStorage()->write($row->toArray());
return 'logged_in';
}
else{return 'failed';}
}
//To check if the user is logged in, use
$userInfo=Zend_Auth::getInstance()->getStorage()->read();
if($userInfo)//user is logged in
I have search and search but no answer I am using Zend Framework to create a user and on success store the record in zend auth so they are automatically logged in.
I have the create user working perfect but after the success I need to start the _getAuthAdpater() and sign the user in.
I have implemented the below code but it will not store the users data in the session. Here is my function.
public function registerAction()
$proUser = new Application_Model_DbTable_ProUser;
$userId = $proUser->addProUser($data['email'], $data['name'], $data['password']);if($userId){
// add new row into proBasic
$proBasic = new Application_Model_DbTable_proBasic;
$proBasic->addProBasic($userId);
// add new row into proService
$proService = new Application_Model_DbTable_proService;
$proService->addProService($userId);
// Create auth session for proUser
$adapter = $this->_getAuthAdapter();
$adapter->setIdentity($data['email']);
$adapter->setCredential($data['password']);
$auth = Zend_Auth::getInstance();
$result = $auth->authenticate($adapter);
if ($result->isValid()) {
$user = $adapter->getResultRowObject(array(
'proId',
'proName',
'proEmail',
));
$auth->getStorage()->write($user);
return true;
}
return $this->_redirect('/auth/probasic/');
}
Here is the _getAuthAdapter() function:
private function _getAuthAdapter()
{
$authAdapter = new Zend_Auth_Adapter_DbTable(Zend_Db_Table::getDefaultAdapter());
$authAdapter->setTableName('proUser')
->setIdentityColumn('proEmail')
->setCredentialColumn('proPassword');
return $authAdapter;
}
I am getting no errors for this code but it isnt store the users details in the Auth. I have found 100's of example of how to create a login/sign up system in Zend and none of them automatically login the user, so I am wondering if I am trying to do something different.
Cheers

You don't really need to authenticate them if you're creating the session immediately after registration. What happens if you replace all your code after $proService->addProService($userId) with just this:
$auth = Zend_Auth::getInstance();
$auth->getStorage()->write($data['email']);
I'm using Zend_Auth with a "Database Table Authentication". What I want to do is allow the user to login with either a username or email address as the "identityColumn". How would I allow both. I'm stuck.
Extend and implement your own Auth Adapter and use query like "WHERE username = ? or email = ?" to get Auth result :)
Authenticate twice (if needed) with 2 different Zend_Auth_Adapter_DbTable objects and add some logic to determine if the login is username or email by guessing if what type of login user provided so that you save one query for most of the cases.
I know this is not the cleanest Zend_Auth implementation, but it works. The only problem comes if someone registers with an different email address as a username, but of course you can prevent this in your registration form. Hope it helps.
// if the entered value validates as an email address then use the 'email' field
// if not, use the 'username' field
$validator = new Zend_Validate_EmailAddress();
if ($validator->isValid($form->getValue('password'))) {
$identityField = 'email';
} else {
$identityField = 'username';
}
$authAdapter = new Zend_Auth_Adapter_DbTable(
$dbAdapter,
'users',
$identityField,
'password',
'SHA1(?)'
);
$authAdapter->setIdentity($form->getValue('username'))
->setCredential($form->getValue('password'));
