Codeigniter如何包含facebook sdk初始化？

Question

Hi I'm beginner in Codeigniter. I have 4 view page that have facebook login (1. login page 2.register page 3.login special member page 4.register special member page)

And all 4 views file I have to initial facebook php sdk like this

<?php require_once(APPPATH.'libraries/facebook/src/facebook.php');
$facebook = new Facebook(array(
  'appId'  => '201637766943985',
  'secret' => '4e70dc1dbfc4787e81bec0d7b57d6a1c',
));


$user = $facebook->getUser();

It's very annoying that one day I have to change appID and appsecret, I have to change it in 4 view files.

so I create new view file name "fb_init.php" that contain code

<?php require_once(APPPATH.'libraries/facebook/src/facebook.php');
    $facebook = new Facebook(array(
      'appId'  => '201637766943985',
      'secret' => '4e70dc1dbfc4787e81bec0d7b57d6a1c',
    ));


    $user = $facebook->getUser();

and then in 4 view files I include fb_init.php by write

$this->load->view('fb_init.php');

However, The problem is the remaining code of facebook php sdk cannot refer to $user variable. the remaining code of facebook sdk is here.

    if ($user) {
      try {
        // Proceed knowing you have a logged in user who's authenticated.
        $user_profile = $facebook->api('/me?fields=id,email,name,first_name,last_name,picture'); //ต้องมีหลัง /me ไม่งั้นประวัติมาไม่ครบ
      } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
      }
    }

$loginUrl = $facebook->getLoginUrl(array(  
    "redirect_uri"=>"http://www.club55.net/login",   
    "scope"=>"email"
  ));

How could I do?

Try this, in your fb_init.php.

$data['user'] = $facebook->getUser();

And in your view file.

$this->load->view('fb_init.php', $data);

if ($user) {
