    Hope this will help you :

    Note : make sure you have load database and upload library either in autoload or in controller

    First your form should be like this :

    <?php echo form_open_multipart('AddPlant/InsertPlant')?>
        ............
     <?php echo form_close();?>
    

    Your controller should be like this :

    public function InsertPlant()
    {
        /*here make sure your path is correct*/
        $config['upload_path']          = FCPATH .'assets/uploads/';
        $config['allowed_types']        = '*';
    
        $this->load->library('upload', $config);
    
        if ( ! $this->upload->do_upload('plantimg'))
        {
            $error = array('error' => $this->upload->display_errors());
            print_r($error);die;
        }
        else
        {
            //$data = array('upload_data' => $this->upload->data());
            $file_name = $this->upload->data('file_name');
            /*here assuming that your column name for image is image_name, change it not*/
            $data =array(
                    'name'=> $this->input->post('name',TRUE),
                    'description'=> $this->input->post('description',TRUE),
                    'age'=> $this->input->post('age',TRUE),
                    'image_name'=> $file_name,
            );
            return $this->db->insert('plants',$data);
        }
    }
