Help user authentication

[voxxxlll]

Hi guys! Im trying to build a facebook login button.So far i built the script to get permission and all details about a user.In the file register.php i put an if statement like this:

if ($fblogin = true ) {

run the script

}

Now if i have all details(name, password, email, avatar) how can i create a new user and authenticate him when $fblogin = true?

In the file register.php i found this function but i dont know how to change it so i can use it for this.

function register_add_user($username, $email, $password, $password2){

	global $current_user;

	$user = new User();
	$user->username = $username;
	$user->pass = $password;
	$user->email = $email;
	if($user->Create()){

		$user->read('short');
		
		$registration_details = array(
			'username' => $username,
			'password' => $password,
			'email' => $email,
			'id' => $user->id
		);
	
		check_actions('register_success_pre_redirect', $registration_details);

		$current_user->Authenticate($username, $password, false);
		if ($registration_details['redirect'])
		    header('Location: '.$registration_details['redirect']);
		elseif(pligg_validate()){
		    header('Location: '.my_base_url.my_pligg_base.'/register_complete.php?user='.$username);
		} else {
		    header('Location: ' . getmyurl('user', $username));
		}
		die();
	}

}

Thank you!

Why don't you use the already-built Facebook Module?
Facebook Connect Module for Pligg CMS | Pligg CMS Templates and Modules

I would like to learn myself how to use facebook API and php.Could you please help me?Thank you!

Honestly the facebook API changes so much. The best bet is to go with a provided solution. However there is nothing wrong with learning. If you want to re-learn their new api every week.

So true. We've had to redo the official Facebook Connect Module 3 times so far, and we are about to do it a fourth time this week. It's really a pain.

the problem is not facebook for me, the problem is that I don't know how to add a new user to pligg database and authenticate him, this was the question.

I found this function which encrypts the password

function generateHash($plainText, $salt = null){

if ($salt === null) {

$salt = substr(md5(uniqid(rand(), true)), 0, SALT_LENGTH); }

else {

$salt = substr($salt, 0, SALT_LENGTH);

}

return $salt . sha1($salt . $plainText);

}

The password is saved in the database alright, but when i try to login says the pass is not correct.

This can be closed!Finally i added facebook login, twitter login and OpenID login without registration.
