Yii防止在刷新时从上传的文件中重新插入数据到数据库

Question

I have an upload form, where I upload csv files and then insert all rows to the database. If I hit refresh, all content is inserted again and again into the database. What is the best prectice to prevent this?

Thanks a lot! BR

Answer 1

The best way to prevent this behavior is to use a redirect to show the landing page. When a redirect is made the browser history records another url after the post action. in Yii you can achieve this by doing the following from the controller.

 $this->redirect("../path/to/action");
