Php 如何显示数据库中的所有行-Laravel 5.2？

我的Laravel应用程序有一个简单的问题。但我找不到任何解决方案。请在此处查看我的代码：

控制器：

public function index(){
    $members = Member::paginate(15);

    $meal_entry = Member::all();
    $breakfast = DB::SELECT("SELECT self_meal_breakfast + guest_meal_breakfast AS breakfast FROM meal_entry");
    $lunch = DB::SELECT("SELECT self_meal_lunch + guest_meal_lunch AS lunch FROM meal_entry");        
    $dinner = DB::SELECT("SELECT self_meal_dinner + guest_meal_dinner AS dinner FROM meal_entry");
    $total_meal = DB::SELECT("SELECT self_meal_breakfast + self_meal_lunch + self_meal_dinner + guest_meal_breakfast + guest_meal_lunch + guest_meal_dinner AS total FROM meal_entry");

    return view('member.mealView', compact('members','data','breakfast','lunch','dinner','meal_entry','total_meal'));
}

<tbody>
    <tr>
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach                                        
        @foreach($breakfast as $value)
        <td>{{ $value->breakfast }}</td>
        @endforeach                                        
        @foreach($lunch as $value)
        <td>{{ $value->lunch }}</td>
        @endforeach                                        
        @foreach($dinner as $value)
        <td>{{ $value->dinner }}</td>
        @endforeach                                        
        @foreach($total_meal as $value)
        <td>{{ $value->total }}</td>
        @endforeach                                        
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach
    </tr>
</tbody>

public function index(){
    $members = Member::paginate(15);

    return view('member.mealView', compact('members'));
}

刀片视图：

public function index(){
    $members = Member::paginate(15);

    $meal_entry = Member::all();
    $breakfast = DB::SELECT("SELECT self_meal_breakfast + guest_meal_breakfast AS breakfast FROM meal_entry");
    $lunch = DB::SELECT("SELECT self_meal_lunch + guest_meal_lunch AS lunch FROM meal_entry");        
    $dinner = DB::SELECT("SELECT self_meal_dinner + guest_meal_dinner AS dinner FROM meal_entry");
    $total_meal = DB::SELECT("SELECT self_meal_breakfast + self_meal_lunch + self_meal_dinner + guest_meal_breakfast + guest_meal_lunch + guest_meal_dinner AS total FROM meal_entry");

    return view('member.mealView', compact('members','data','breakfast','lunch','dinner','meal_entry','total_meal'));
}

<tbody>
    <tr>
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach                                        
        @foreach($breakfast as $value)
        <td>{{ $value->breakfast }}</td>
        @endforeach                                        
        @foreach($lunch as $value)
        <td>{{ $value->lunch }}</td>
        @endforeach                                        
        @foreach($dinner as $value)
        <td>{{ $value->dinner }}</td>
        @endforeach                                        
        @foreach($total_meal as $value)
        <td>{{ $value->total }}</td>
        @endforeach                                        
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach
    </tr>
</tbody>

public function index(){
    $members = Member::paginate(15);

    return view('member.mealView', compact('members'));
}

@foreach（$进餐费作为$value）
{{$value->created_at}
@endforeach
@foreach（早餐价值$value）
{{$value->早餐}
@endforeach
@foreach（午餐价值$value）
{{$value->午餐}
@endforeach
@foreach（晚餐价值$value）
{{$value->晚餐}
@endforeach
@foreach（$总膳食价值）
{{$value->total}
@endforeach
@foreach（$进餐费作为$value）
{{$value->created_at}
@endforeach

和表格：

---

如果数据库中有一个

行

，则可以查看（）。但是当有多个

行

时，它会显示在一个

行

，包含所有数据（）。我如何处理这些事情？我认为应该运行另一个循环，但我如何才能做到这一点？提前感谢。

因此，如果您使用的是Laravel，访问器是其中一个最好的功能：

可以创建新属性并将其用作模型属性

因为有些东西很有用

class Meal extends Model
{
    public function getTotalBreakfastAttribute()
    {
        return $this->self_meal_breakfast + $this->guest_meal_breakfast;
    }
}

然后，将此访问器用作属性：

<tbody>
   @foreach($foods as $value)
    <tr>
       <td> {{$value->total_breakfast}} </td> 
       <td> {{$value->created_at}} </td>
    </tr>
  @endforeach
</tbody>

@foreach（食品价值为美元）
{{$value->total_早餐}
{{$value->created_at}
@endforeach

或者，如果您不想这样做，请不要使用多个查询来获取数据，只需使用一个查询，因为所有字段都在同一个表中，然后可以使用上面的示例

享受！：）

快速修补程序是只执行一个查询，然后在视图上执行计算（我知道在视图中执行计算不是一个好的做法，但这是我能看到的最简单的方法）

是这样的:

控制器：

public function index(){
    $members = Member::paginate(15);

    $meal_entry = Member::all();
    $breakfast = DB::SELECT("SELECT self_meal_breakfast + guest_meal_breakfast AS breakfast FROM meal_entry");
    $lunch = DB::SELECT("SELECT self_meal_lunch + guest_meal_lunch AS lunch FROM meal_entry");        
    $dinner = DB::SELECT("SELECT self_meal_dinner + guest_meal_dinner AS dinner FROM meal_entry");
    $total_meal = DB::SELECT("SELECT self_meal_breakfast + self_meal_lunch + self_meal_dinner + guest_meal_breakfast + guest_meal_lunch + guest_meal_dinner AS total FROM meal_entry");

    return view('member.mealView', compact('members','data','breakfast','lunch','dinner','meal_entry','total_meal'));
}

<tbody>
    <tr>
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach                                        
        @foreach($breakfast as $value)
        <td>{{ $value->breakfast }}</td>
        @endforeach                                        
        @foreach($lunch as $value)
        <td>{{ $value->lunch }}</td>
        @endforeach                                        
        @foreach($dinner as $value)
        <td>{{ $value->dinner }}</td>
        @endforeach                                        
        @foreach($total_meal as $value)
        <td>{{ $value->total }}</td>
        @endforeach                                        
        @foreach($meal_entry as $value)
        <td>{{ $value->created_at }}</td>
        @endforeach
    </tr>
</tbody>

public function index(){
    $members = Member::paginate(15);

    return view('member.mealView', compact('members'));
}

刀片视图

<tbody>
    @foreach($members as $meal_entry)
    <tr>
        <td>{{ $meal_entry->created_at }}</td>

        <td>{{ $breakfast = $meal_entry->self_meal_breakfast + $meal_entry->guest_meal_breakfast }}</td>

        <td>{{ $lunch = $meal_entry->self_meal_lunch+ $meal_entry->guest_meal_lunch}}</td>

        <td>{{ $dinner = $meal_entry->self_meal_dinner + $meal_entry->guest_meal_dinner }}</td>

        <td>{{ $breakfast + $lunch + $dinner }}</td>

        <td>{{ $meal_entry->created_at }}</td>
    </tr>
    @endforeach 
</tbody>

您需要分页链接的位置。

请告诉我们表格的外观如何？谢谢@伊迪鲁哈布梅斯金当然。。。因为数据在一个表中。您应该执行单个查询。@KinshukLahiri如何使用单个查询执行该操作？因为我有一些不同的算术计算。你能给我看一下吗？你应该只有一个，然后循环。请，你能给我们看一下桌子是什么样子吗？谢谢@伊迪鲁哈布梅斯金当然。。。因为数据在一个表中。您应该执行单个查询。@KinshukLahiri如何使用单个查询执行该操作？因为我有一些不同的算术运算。你能给我看一下吗？不是这四个查询，而是早餐等等。你应该只有一个，然后循环进去。是的，这就是我要找的东西。A+++是的，这就是我要找的东西。A+++
