I have made a login with facebook that adds the user to my database if they haven't been added yet. I want to show other facebook friends (of the current user that just signed up) that have signed up for my app as well.. I am trying to do this by looping through the facebook friends using $this->facebook->api('/me/friends') and finding matches in my database (by id) and storing those in an array that is sent to a view (code igniter)
But So far I havent been able to loop through the users friends so easily. It keeps coming up with,
Undefined index: id
Here is my code:
dashboard controller:
public function index() {
if ($this->user) {
try{
$data['user_profile'] = $this->facebook->api('/me');
$data['friends_list'] = $this->Users_Model->get_friends_on_drimmly($this->facebook->api('/me/friends'));
} catch(FacebookApiException $e) {
error_log($e);
$this->user = null;
}
}
$data['logout'] = $this->facebook->getLogoutUrl(array('next' => base_url().'login/logout'));
$this->load->view('dashboard', $data);
}
users_model:
public function get_friends_on_drimmly($user_friends) {
$return_array = array();
foreach ($user_friends as $friend => $row) {
$query = $this->db->select()->from('users')->where('id', $row['id'])->get();
if ($query->num_rows() != 0){
foreach ($query->result_array() as $result => $row) {
$return_array[] = array(
'name' => $row['full_name'],
'id' => $row['id']
);
}
}
}
return $return_array();
}
UPDATE: print_r($user_friends):
Array ( [data] => Array ( [0] => Array ( [name] => Daniella Caspers [id] => 6710741 ) [1] => Array ( [name] => Alex Dos Santos [id] => 10029005 )....
