When using tp3.3 for project development, many times the codes for additions, deletions, modifications and checks are basically the same, especially the controller part. However, the same code in each controller needs to be written again.
Learned design Pattern, what kind of pattern can be used in this case to reduce the amount of code duplication. It is best to use design pattern

For example, create rbac system:

This is the basic code for my administrator controller's add, delete, modify and check. Except for the different model classes created by the constructor, the basic add, delete, modify and check structures are similar. How can I reduce duplicate code? I hope an expert can give me some advice. Thank you. .

protected $_model; public function __construct(){ parent::__construct(); $this->_model=new MannagerModel(); } /** * 管理员添加 */ public function addC(){ if(IS_POST){ $data=I('post.'); $res=$this->_model->Store($data); $this->redirectUrl($res,'listC'); } $this->display(); } /** * 管理员列表显示 * @return [type] [description] */ public function listC(){ $data=$this->_model->lists(); $this->assign('lists',$data); $this->display(); } /** * 管理员删除 * @return [type] [description] */ public function delC(){ $id=intval(I('get.id')); $res=$this->_model->del($id); //跳转判断函数 $this->redirectUrl($res); } /** * 管理员更新 * @return [type] [description] */ public function editC(){ $id=intval(I('get.id')); //where的数组形式 $where['id']=$id; // 显示旧数据 $old=$this->_model->lists($where); $this->assign('old',$old); //存储新的数据 if(IS_POST){ $data=I('post.'); $res=$this->_model->edit($id,$data); $this->redirectUrl($res,'listC'); } $this->display(); }
