How can i post value from Ajax to Controller (Codeigniter)

Question

Post data includes that name and surname. These datas are posted (show request console) but firebug give me 404 error about "POST localhost/index.php/getdata/ 404 Not Found"

function gonder(){
    $.ajax({
        type:'POST',
        url:'/index.php/getdata/',
        data:$('#form1').serialize(),
        success: function (msg) {
            $('#yaz').html(msg);
            $('#btn').removeAttr('disabled');
        }
    });
}

public function getdata()
    {
        $this->output->set_content_type('application/json');
        if ( ! isset($_POST['data']))
        {
            $data = FALSE;
        }
        else
        {
            $data = $_POST['data'];
        }
        $this->load->view("getdata_view");
        $data = $this->input->post('data');
        var_dump($data);
    }

Answer 1

Check your path..is '/index.php/getdata/' the right path?

It should be /index.php/yourcontrollername/yourmethodname(getdata in your case).
