Dear community,
I am using Abraham\TwitterOAuth php library for Twitter API .I am working on Codeigniter framework. I am trying to get user followers.when user authorize the callback url is called It is ok till then but redirected to callback function session variable stored gets destroyed automatically. I am highly troubled and stuck here for 3 days. Please help would be highlt appreciated. I have created a library on top of Abraham\twitterOAuth.This is the library I made.
//application/libraries
class Twitter {
public function __construct() {
$ci =& get_instance();
if($this->ci->session->userdata('tw_access_token')) $access_token = $this->ci->session->userdata('tw_access_token'); else $access_token = false;
if ( $access_token && isset($access_token['oauth_token']) && isset($access_token['oauth_token_secret']) ) {
$this->tw = new TwitterOAuth(TWITTER_APP_KEY, TWITTER_APP_SECRET,$access_token['oauth_token'], $access_token['oauth_token_secret']);
$this->tw_access_token = $access_token;
$this->tw_user_id = ( isset($access_token['user_id']) ? $access_token['user_id'] : null);
$this->tw_user_name = ( isset($access_token['screen_name']) ? $access_token['screen_name'] : null);
} else {
$request_token = $this->ci->session->userdata('tw_request_token');
if ( $request_token && isset($request_token['oauth_token']) && isset($request_token['oauth_token_secret']) ) {
$this->tw= new TwitterOAuth(TWITTER_APP_KEY, TWITTER_APP_SECRET, $request_token['oauth_token'], $request_token['oauth_token_secret']);
$this->tw_request_token = $request_token;
} else {
$this->tw= new TwitterOAuth(TWITTER_APP_KEY, TWITTER_APP_SECRET);
}
}
// $this->tw_config = $config;
$this->tw_status=isset($_SESSION['tw_status'])?$_SESSION['tw_status']:false;
$this->host = 'https://api.twitter.com/1.1/'; // Use API v1.1
}
public $tw_user_id = null;
public $tw_user_name = null;
public $tw_user_info = null;
public $tw_request_token = null;
public $tw_access_token = null;
public $tw_status = null;
public $tw;
/**
* to get login url
*/
public function getLoginUrl($callback_url = '') {
if ($callback_url == '') {
$callback_url =TWITTER_APP_REDIRECT_URI;
}
$request_token =$this->tw->oauth('oauth/request_token', array('oauth_callback' => $callback_url));
$token = $request_token['oauth_token'];
//this session is set here which gets destroyed
`$_SESSION['tw_request_token']= $request_token;`
return ( $this->tw->url('oauth/authorize', array('oauth_token' => $request_token['oauth_token'])) );
}
/**
* 3. Requests permanent access token after callback
*/
public function twprocess_callback() {
//no session is available
print_r($_SESSION];
$returned_request_token = $this->input->get('oauth_token');
$request_token = $this->tw_request_token;
if ($returned_request_token) {
if ( $request_token['oauth_token'] != $returned_request_token) {
// echo 'The oauth_token is old, deleting it and returning false';
$this->session->unset_userdata('tw_request_token');
// unset($_SESSION['tw_request_token']);
$this->tw_request_token = null;
$this->tw_status = 'old_token';
$this->session->set_userdata('tw_status', 'old_token');
// $_SESSION['tw_status']= $old_token;
return false;
} else {
// echo 'Request access tokens from twitter';
$access_token = $this->tw->getAccessToken($this->input->get('oauth_verifier'));
$this->tw_access_token = $access_token;
$this->tw_user_id = $access_token['user_id'];
$this->tw_user_name = $access_token['screen_name'];
$this->session->set_userdata('tw_access_token', $access_token);
$this->session->unset_userdata('tw_request_token');
// unset($_SESSION['tw_request_token']);
return true;
}
} else return false;
}
Now I call function get getLoginUrl() to get url and when user clicks goes to a callback function.But when i call function
`
//call back function redirected by app`
public function signup_twitter(){
$this->load->library('Twitter');
print_r($this->session->userdata);
$ok= $this->twitter->twprocess_callback();
}
The session in function signup_twitter ans in twprocess_callback gets destroyed .
Please let me know if I am wrong or any thing is missing
