How can I integrate Facebook with IonAuth2?

I'm developing an application that requires users to login either via Facebook or their own email address. I have experience using the IonAuth2 library, but I'm unsure about integrating it with Facebook based on the documentation provided.

Can anyone offer advice on how to integrate Facebook into IonAuth2 seamlessly? Alternatively, should I consider using another Codeigniter library for this purpose? I have successfully set up a Facebook application and implemented the API for login, as shown in the code snippet below. However, I'm specifically looking for the best approach to integrate this with the authentication system, preferably using IonAuth2.

public function index()
{
  $user = $this->facebook->getUser();

  if ($user) {
    try {
        $user_info = $this->facebook->api('/me');
        echo '<pre>'.htmlspecialchars(print_r($user_info, true)).'</pre>';
        echo 'user found';
        // save this info..
        $this->load->model('fb_users_model');
        $this->fb_users_model->insert_user($user_info); // id, first_name, last_name, link, username, gender, email, timezone, locale, verified, updated_time

        echo 'we have logged in..go to some page..';
        echo "<a href=/logout>Logout</a>";
    } catch (FacebookApiException $e) {
        echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
        $user = null;
    }
  } else {
      echo "<a href=\"{$this->facebook->getLoginUrl()}\">Login using Facebook</a>";
  }
}
Any suggestions or guidance on accomplishing this integration effectively would be highly appr

Those Social Media sites use OAuth.

Even though IonAuth2 doesn't enable Facebook login natively, your code example demonstrates how to integrate it successfully via the Facebook API. However, if you find the integration procedure difficult or time-consuming, you might think about investigating additional CodeIgniter libraries created especially for social authentication, like HybridAuth or Opauth, which offer more thorough support for a variety of social login providers, including Facebook.

To integrate Facebook login with IonAuth2:

Create a new controller called FacebookAuthController.
Create a new action called login() in the FacebookAuthController.
In the login() action, get the Facebook user ID and user info using the Facebook API. You can use the following code:
$user_id = $this->facebook->getUser();

if ($user_id) {
try {
$user_info = $this->facebook->api('/me');
} catch (FacebookApiException $e) {
$user_id = null;
}
}
Check if the user is already registered with your application. You can use the following code:
$this->load->model('ion_auth_model');

if (!$this->ion_auth_model->identity_check($user_info['email'])) {
Register the user with your application using the IonAuth2 library. You can use the following code:
$this->ion_auth_model->register($user_info['email'], $user_info['name'], '', $user_info['email'], '', '', true);

Log the user in with your application using the IonAuth2 library. You can use the following code:
$this->ion_auth_model->login($user_info['email'], '');
Redirect the user to the homepage of your application.
Here is an example of a FacebookAuthController that implements the above steps:

class FacebookAuthController extends MY_Controller
{
public function login()
{
$user_id = $this->facebook->getUser();

if ($user_id) {
try {
$user_info = $this->facebook->api('/me');
} catch (FacebookApiException $e) {
$user_id = null;
}
}

if ($user_id) {
$this->load->model('ion_auth_model');

if (!$this->ion_auth_model->identity_check($user_info['email'])) {
$this->ion_auth_model->register($user_info['email'], $user_info['name'], '', $user_info['email'], '', '', true);
}

$this->ion_auth_model->login($user_info['email'], '');

redirect("/");
} else {
$loginUrl = $this->facebook->getLoginUrl();

redirect($loginUrl);
}
}
}

You can then use the following code to add a Facebook login button to your application:

<a href="/facebookauth/login">Login using Facebook</a>
When the user clicks on the Facebook login button, they will be redirected to Facebook to log in. Once they have logged in to Facebook, they will be redirected back to your application and logged in.

This is just a basic example of how to integrate Facebook login with IonAuth2. You may need to modify the code to meet your specific needs.

Thank you, I will say give it a try！！
