    <div class="panel-body">
        <?php echo form_open_multipart('add_new_category/do_upload');?>
        <center>
        <?php if (validation_errors()): ?>

            <div class="alert alert-danger alert-dismissible" role="alert" style="width: 700px;">

model:

public function insert_cat($file)
{
    // $this->db->insert('product_table',$file);
    if($this->db->insert('product_category', $file))
    {
        return TRUE;
    }else
    {
        return FALSE;
    }
}

Answer 1

Add one more function in model

    public function insert_cat1($file){
            $this->db->insert('product_table',$file);

           {
                return TRUE;
           }else
           {
              return FALSE;
          }
        } 

And change the controller


    function do_upload() {
            $config['upload_path'] = './assets/';
            $config['allowed_types'] = 'gif|jpg|png';
            $config['max_size'] = '2000';
            $config['max_width'] = '2000';
            $config['max_height'] = '2000';
            $config['new_image'] = './assets/';

            $config['overwrite'] = TRUE;
            $this->load->library('upload', $config);
            $this->form_validation->set_rules('name', 'Category Name', 'required');
            if (!$this->upload->do_upload() || !$this->form_validation->run()) {
                $error = array('error' => $this->upload->display_errors());
                $this->session->set_flashdata("message2","Product not added");
             redirect('add_products','refresh');
            } else {

                $data = $this->upload->data();
                $this->thumb($data);


                $file = array(
                    'img_name' => $data['raw_name'],
                    'thumb_name' => $data['raw_name'] . '_thumb',
                    'ext' => $data['file_ext'],
                    'category' =>$this->input->post('name')  


                );
                  $data = array('upload_data' => $this->upload->data());
                 $insert1=$this->User->insert_cat($file);
                 $insert2=$this->User->insert_cat1($file);
               if(($insert1)&&($insert2)==TRUE)
         {
            $this->session->set_flashdata("message","You Have Successfully Added a new Category!");
            redirect('add_category','refresh');
         }else
         {
             $this->session->set_flashdata("message2","Category not added");
             redirect('add_category','refresh');
          }
          }
          }
