データベース、購入テーブル、販売テーブル、在庫テーブルの3つのテーブルを希望

Question

購入フィールドにデータを挿入しています。今私は株価表が欲しい、後に私が売り上げテーブルから売り上げ商品であるときに私は株式を更新したい。

私のコントローラ

public function add_purchase() { 
    $data = array(); 

    $data['maincontent'] = $this->load->view('pages/add_purchase', $data, true); 
    $this->load->view('master', $data); 
} 

public function save_purchase() { 
    $this->Super_Admin_Model->save_purchase_info(); 
    redirect('Super_Admin/add_purchase'); 
} 

マイモデル

public function save_purchase_info() { 
    $data = array(); 
    $data['material_id']= $this->input->post('material_id',true); 
    $data['pur_date']= $this->input->post('pur_date',true); 
    $data['pur_qty']= $this->input->post('pur_qty',true); 
    $data['unit_id'] = $this->input->post('unit_id', true); 
    $data['pur_unit_price']= $this->input->post('pur_unit_price',true); 
    $data['total_price']= $this->input->post('total_price',true); 

    $this->db->insert('tbl_purchase', $data); 
}
