Laravel删除产品-CRUD之delete(destroy)

　　上一篇讲了Laravel编辑产品-CRUD之edit和update，现在我们讲一下删除产品，方法和前面的几篇文章类似，照着ytkah来操作吧

　　1,controller的function destroy定义，注意这里的Name是destroy（controller的function查看方法在这），文件在/app/Http/Controllers/ItemController.php

?

1 2 3 4 5

public function destroy($id) {     $item = Item::find($id);     $item->delete(); }

　　2,模板的编辑，有两个地方，show.blade.php和index.blade.php，用<input type="hidden" name="_method" value="DELETE">的方法

show.blade.php模板修改
