Step 1:<\/strong>
\nDownload the latest codeigniter\u00a0and configure into your localhost.Check once after completing the configuration.
\nhttp:\/\/localhost\/codeigniter<\/p>\n

Step 2:<\/strong>
\nNext download the facebook sdk from below URL : https:\/\/github.com\/facebook\/facebook-php-sdk and unzip the folder.
\nFind ”Src” folder.\u00a0Open src folder there you will find three files which are
\n1)\u00a0\u00a0 \u00a0base_facebook.php
\n2)\u00a0\u00a0 \u00a0facebook.php
\n3)\u00a0\u00a0 \u00a0fb_ca_chain_bundle.crt<\/p>\n

Step 3:<\/strong>
\nCopy the files and paste after opening\u00a0codeigniter\u00a0folder, then go to the application folder and next go to the libraries folder
\ncodeigniter->application->libraries, paste these files and change the\u00a0name of the file from \u201cfacebook.php\u201d to \u201cFacebook.php”.<\/p>\n

Step 4:<\/strong>
\nNext go to codeigniter\u00a0folder and create one file name as \u201c.htaccess\u201d

\u201cRewriteEngine On\r\nRewriteCond %{REQUEST_FILENAME} !-f\r\nRewriteCond %{REQUEST_FILENAME} !-d\r\nRewriteRule ^(.*)$ index.php\/$1 [L]\u201d\r\n<\/pre>\n
Step5:<\/strong>
\nCreate login controller go to
\nCodeignator->application->controllers
\nFile name \u201clogin.php\u201d<\/p>\n
<?php\r\nclass login extends CI_Controller {\r\npublic function __construct(){\r\nparent::__construct();\r\nparse_str($_SERVER['QUERY_STRING'],$_REQUEST);\r\n$this->load->library('Facebook', array(\"appId\"=>\"you app id\", \"secret\"=>\"app secret key\"));\r\n$this->user = $this->facebook->getUser();\r\n}\r\npublic function index() {\r\nif($this->user) {\r\ntry{\r\n$user_profile = $this->facebook->api('\/me');\r\necho $user_profile['email'];\r\necho \"<pre>\"; print_r($user_profile);\r\n}catch(FacebookApiException $e){\r\nprint_r($e);\r\n$user = null;\r\n}\r\n}\r\nif($this->user){\r\n$logout = $this->facebook->getLogouturl(array(\"next\"=>base_url().\"login\/logout\"));\r\necho \"<a href='$logout'>Logout<\/a>\";\r\n}else\r\n{\r\n$data['url'] = $login = $this->facebook->getLoginUrl(array(\"scope\"=>\"email\"));\r\n$this->load->view('login', $data);\r\n}\r\n}\r\npublic function logout() {\r\nsession_destroy();\r\nredirect(base_url().'login');\r\n}\r\n}\r\n?>\r\n<\/pre>\n
Step6:<\/strong>
\nCreate login view,go to
\nCodeignator->application->views
\nFile name \u201clogin.php\u201d<\/p>\n
