Question

How to build a post model and controller with Multiple File Upload in yii2 with the all types of files when creating a new post that I can get a Post with slider?

Solution

For Upload Multiple Files, follow the official tuto: https://github.com/yiisoft/yii2/blob/master/docs/guide/input-file-upload.md

With files in folder, you can use Yii2 Galery or bootstrap\Carousel (in this post).
