Now I want to access model function in controller and pass record id in data function How I do ??

Answer 1

set return in model and in controller write
$insert_id=$this->db->insert_id();

Answer 2

In Controller load your model first using
$this->load->model('model_name');
Then call to model's getLastInserted() function.
$ID = $this->model_name->getLastInserted();//you will get id here
In model return $query->row()->userid; insead return of $query->result().
Then modify the controller:
public function newregistration()
{
if ($this->form_validation->run())
{
$data = array(
'UserID'=> $this->model_name->getLastInserted(),
'Name' => $this->input->post('Name'),
'MobileNo' => $this->input->post('MobileNo'),
'IMEINumber' => $this->input->post('IMEINumber'),
'City' => $this->input->post('City')
);
$this->adminmodel->insertregistration($data);
}
}

hi i worked out the solution on last inserted id dear here the code:
controller:
function sample() {
$sid=$this->adminmodel->getLastInserted();
$this->adminmodel->newregistration( $sid);
}
model:
function getLastInserted()
{
$query = $query = $this->db->select('id')->order_by('id','desc')->limit(1)->get('employee_outs')->row('id');
return $query;
}
model:
public function newregistration($sid)
{
if ($this->form_validation->run())
{
$data = array(
'UserID'=> $sid,
'Name' => $this->input->post('Name'),
'MobileNo' => $this->input->post('MobileNo'),
'IMEINumber' => $this->input->post('IMEINumber'),
'City' => $this->input->post('City')
);
$this->adminmodel->insertregistration($data);
}
}
