Laravel展示产品-CRUD之show

　　上一篇讲了Laravel创建产品-CRUD之Create and Store，现在我们来做产品展示模块，用到是show，①首先我们先修改controller，文件是在/app/Http/Controllers/ItemController.php，定义一下show function

?

1 2 3 4 5

public function show($id) {     $item = Item::find($id);     return view('items.show')->with('item', $item); }

　　②创建show模板，文件是/resources/views/items/show.blade.php，添加如下代码

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49
