• laravel用crud之index列出产品items


      前面我们说了laravel用crud修改产品items-新建resource controller和routing,现在我们要把产品items罗列出来,需要修改路由和模板,一起随ytakh来看看把

      1,修改controller,/app/Http/Controllers/ItemController.php

    use AppItem;
    //还有下面的index定义
        public function index()
        {
            //
          $items = Item::all();
            return view('items.index')->with('items',$items); 
        }
    

      2,修改index.blade.php模板

    @extends('layouts.app')
    
    @section('content')
    <div class="container">
    	<div class="row">
    		<div class="col-md-12">
    			<div class="panel panel-default">
    				<div class="panel-heading">List of Items</div>
    				<div class="panel-body">
    					<table class="table">
    						<thead>
    							<tr>
    								<th>#</th>
    								<th>Name</th>
    								<th>Price</th>
    								<th>Img</th>
    								<th>description</th>
    								<th>Created At</th>
    								<th>Update At</th>
    								<th>Actions</th>
    							</tr>
    						</thead>
    						<tbody>
    							@foreach($items as $item)
    								<tr>
    									<td>{{$item->id}}</td>
    									<td>{{$item->name}}</td>
    									<td>{{$item->price}}</td>
    									<td>{{$item->img}}</td>
    									<td>{{$item->description}}</td>
    									<td>{{$item->created_at}}</td>
    									<td>{{$item->updated_at}}</td>
    									<td>
    										<a class="btn btn-primary" href="{{route('items.show', '$item->id')}}">view</a>
    										<a class="btn btn-danger" href="{{route('items.destroy', '$item->id')}}">delete</a>
    									</td>
    								</tr>
    							@endforeach
    						</tbody>						
    					</table>
    					<a class="btn btn-primary" href="{{route('items.create')}}">Create New Item</a>
    				</div>
    			</div>
    		</div>
    	</div>
    </div>
    @endsection
    

      上面是用于产品比较少的情况,如果产品多了,我们就要进行分页才好点,怎么做分页呢?用到paginate

      1,修改controller,/app/Http/Controllers/ItemController.php

    use AppItem;
    use DB;
    //还有下面的function定义
        public function index()
        {
            //
            $items = DB::table('items')->paginate(10);//可以调整数字大小,表示一页显示多少各产品
            return view('items.index')->with('items',$items); 
        }
    

    如果要降序排列,即最新上传的产品放在前面,用 ->latest()

    $items = DB::table('items')->latest()->paginate(1);
    

      修改index.blade.php模板

    @extends('layouts.app')
    
    @section('content')
    <div class="container">
    	<div class="row">
    		<div class="col-md-12">
    			<div class="panel panel-default">
    				<div class="panel-heading">List of Items</div>
    				<div class="panel-body">
    					<table class="table">
    						<thead>
    							<tr>
    								<th>#</th>
    								<th>Name</th>
    								<th>Price</th>
    								<th>Img</th>
    								<th>description</th>
    								<th>Created At</th>
    								<th>Update At</th>
    								<th>Actions</th>
    							</tr>
    						</thead>
    						<tbody>
    							@foreach($items as $item)
    								<tr>
    									<td>{{$item->id}}</td>
    									<td>{{$item->name}}</td>
    									<td>{{$item->price}}</td>
    									<td>{{$item->img}}</td>
    									<td>{{$item->description}}</td>
    									<td>{{$item->created_at}}</td>
    									<td>{{$item->updated_at}}</td>
    									<td>
    										<a class="btn btn-primary" href="{{route('items.show', '$item->id')}}">view</a>
    										<a class="btn btn-danger" href="{{route('items.destroy', '$item->id')}}">delete</a>
    									</td>
    								</tr>
    							@endforeach
    						</tbody>						
    					</table>
    					<div class="text-center">{{$items->links()}}</div>//分页链接					
    					<a class="btn btn-primary" href="{{route('items.create')}}">Create New Item</a>
    				</div>
    			</div>
    		</div>
    	</div>
    </div>
    @endsection
