php - Facebook connect with codeigniter redirect in loop after login -


i trying connect facebook using codeigniter. if connecting fist time,then can see permission popup after authorise permission getting multiple redirect loop error.

if logged in , authorised site why not getting uid.

i have give site url in facebook: http://mysite.com/

and redirect uri http://mysite.com/facebook/

i have added these files in library folder.

library/fb_connect.php library/facebook/facebook.php library/facebook/base_facebook.php library/facebook/fb_ca_chain_bundel.crt

last 3 files in facebook folder facebook sdk files.

here code in fb_connect.php

<?php include(apppath.'libraries/facebook/facebook.php');   class fb_connect {   function connect(){   $facebook = new facebook(array(     'appid'  => 'xxxxxxx',     'secret' => 'xxxxxxxxxxxxxx',     'cookie' => true,  ));      //get user id   $user=$facebook->getuser();    if(!$user){    $loginurl=$facebook->getloginurl(array(     'scope'         => 'email,publish_stream,user_birthday,user_location',     'redirect_uri'  => 'http://localhost/beta/facebook/',     'display'=> 'popup'     ));      redirect($loginurl')";     exit();    } else { $user_profile = $facebook->api('/me');   print_r($user_profile);  }  ?>

and here controller code:

function  facebook(){    $this->load->library('fb_connect');   $user_data=$this->fb_connect->connect();   }

there's few things;

1.you said "and redirect uri http://mysite.com/facebook/" - in code:

'redirect_uri'  => 'http://localhost/beta/facebook/',

should be:

'redirect_uri'  => 'http://mysite.com/facebook/',

2.you said "i have give site url in facebook: http://mysite.com/" - need set return url in facebook api aswell - should "http://mysite.com/facebook"

3.you said redirect "http://mysite.com/facebook/" - have set route? because should "http://mysite.com/mycontroller/facebook/"

4.you have typo (if copy + paste):

redirect($loginurl')";

should be

redirect($loginurl);
