Model.php

public function add_doct()
{
//$data = $this->db->select(`name`)->get($this->product)->result_array();
$name = $this->input->post('name');
$images = $this->input->post('images');
//print_r($image); die();
$this->db->where('name',$name);
$p = $this->db->get('product')->row();
    if (empty($p)) {
      $data = array(

      'name'=>$this->input->post('name'),
      'images'=>$this->input->post('images')
      );
      $this->db->insert('product',$data);
      return 1;
    }
    else
    {
    return 0;
    }

}


Controller.php
public function add_doct()
{
$this->load->model('Doctor');
$data['page_title'] = "Add Product List";
if($this->input->post())
{
$values = $this->input->post();
$config['upload_path']          = './uploads';
$config['allowed_types']        = 'png|jpg|jpeg|gif';
$this->load->library('upload', $config);
$filedata['file_name'] = "";
$error = "";
if (!$this->upload->do_upload('images')):
    $error = array('error' => $this->upload->display_errors());
    //print_r($error); die();
else:
    $filedata = array('upload_data' => $this->upload->data());
endif;
if($error==""):
$values['images'] = $filedata['upload_data']['file_name'];
endif;
//$values['creation_date'] = time();
$datas = array(

      'name'=>$values['name'], //database name 'name'
      'images'=>$values['images'] //database name images
      );
$this->db->insert("database Name",$datas);
$this->session->set_flashdata("success_msg","Pruduct has been created");
redirect(base_url('admin/drdetailing/add_productlist'));
$this->load->template('admin/drdetailing/add_productlist',$data,1);
}
if($ins == 1){
$this->session->set_flashdata('message_name','Data Submitted');
redirect('admin/drdetailing/view_productlist');
}else{
$this->session->set_flashdata('message_name','This name allready exist');
redirect('admin/drdetailing/view_productlist');
}
$data['page_title'] = "Add Doctor & you can change name";
$this->load->template('admin/drdetailing/add_productlist',$data,1);
