Using $this when not in object context in Codeigniter

Question

I know this question already has answers but I did not understand so asked again So please help.

What does this error actually mean ?

Fatal error: Using $this when not in object context in C:\wamp\www\provisioning\application\controllers\customer\provisioning.php on line 27

public function index(){
  $users = $this->data['tenant_users'] = $this->customer_user_m->tenant_users();
  $domain = $users[0]['domain'];
  $site = $users[0]['site_key'];
  $tenant_id = $users[0]['tenant_id'];
  $site = $this->session->userdata('site');
  $user_table = $this->session->userdata('user_table');

  function getOTAURLExt($ext){
    var_dump($this);
  }

  function getOTAURLSite(){
    echo "Site executed";
  }

  $this->db->select('*');
  $this->db->where('id', $tenant_id);
  $this->db->from('tenant');
  $query = $this->db->get();
  $result = $query->result_array();

  if(empty($this->input->post('md'))){
    $URL = getOTAURLSite($site);
  }else{

    $username = $result[0]['username'];

    $table_user = $username . "_users";


    $this->db->select('*');
    $this->db->where($table_user . '.site_key', $site);
    $this->db->join('mlcsites', 'mlcsites.site_key =' . $table_user . '.site_key');
    $this->db->from($table_user);
    $query_table = $this->db->get();
    $information = $query_table->result_array();


    $ext = $information[0]['ext'];


    $count = count($information);
    $found = false;
    for($i = 0; $i < $count; $i++){
      $domain = $information[$i]['domain'];
      $ext = $information[$i]['ext'];

      $hash = do_hash($ext . "@" . $domain, 'md5');

      if($hash == $this->input->post('md')){

        $found = true;
        break;
      }
    }

    if($found == true){
      $URL = getOTAURLExt($ext);
    }
  }
  if(empty($URL)){

  }

  $this->data['subview'] = 'provisioning/index';
  $this->load->view('_layout_main', $this->data);
}

What could be the possible solution to this?

@DavidJawphan ignore it , It should be like this $this->data['tenant_users'] =$this->customer_user_m->tenant_users();` so i will pass tenant_users array to view — Rajan

As per the code that you provided, there seems to be nothing on "line 27" so IMHO it seems to be caused on "line 10"

function getOTAURLExt($ext){
    var_dump($this); // <<< This seems to be causing error.
}

Now If you need the variable $this inside the function you could either

Pass it as an Argument (If you only need to read values from the object).
Pass it by Reference (If you need to update the object.).
Declare it Global.

...then use it inside the function.
