Codeigniter, create directory - codeigniter

Question

I'm new on Codeigniter.
I have a problem & looking for some help.
I want to create directory when I input the data to a database with a directory name, which comes from the array when create a database. If I make a directory with specific name it works.
public function insert()
{
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
$this->form_validation->set_rules('dname', 'Name', 'required|min_length[5]|max_length[50]');
$this->form_validation->set_rules('ddate', 'Date', 'required|date_valid');
if ($this->form_validation->run() == FALSE){
$this->loading_content('admin/new_event');
} else {
$panggil = array(
'name' => $this->input->post('dname'),
'event_date' => $this->input->post('ddate')
);
$path ="./lainnya/img/event/".$data->name."/";
mkdir($path, 0777); --> THIS CODE NOT WORKING
// mkdir("lainnya/img/event/okdeh",0777); --> THIS CODE IS WORKING
$this->m_event->form_insert($panggil);
$data['message'] = 'Data Inserted Successfully';
$this->loading_content('admin/event', $panggil);
}
}
Thanks for your help.

i already found the answer... Maybe someone out there need it..
public function insert()
{
$this->load->library('form_validation');
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
$this->form_validation->set_rules('dname', 'Name', 'required|min_length[5]|max_length[50]');
$this->form_validation->set_rules('ddate', 'Date', 'required|date_valid');
if ($this->form_validation->run() == FALSE){
$this->loading_content('admin/new_event');
} else {
$panggil = array(
'name' => $this->input->post('dname'),
'event_date' => $this->input->post('ddate')
);
//$path ="./lainnya/img/event/".$panggil->'name'."/"; ---> **BEFORE**
$path ="./lainnya/img/event/".$panggil->['name']."/"; -- **NOW**
mkdir($path, 0777);
$this->m_event->form_insert($panggil);
$data['message'] = 'Data Inserted Successfully';
$this->loading_content('admin/event', $panggil);
}
}
