Question

对于DB中的每个表，我都有四个带有CRUD的刀片。

在homeblade中，我需要一个表，可以在每个表中放一列，然后将其填充到列中，而不是一行中。

这是我在刀片中的代码：

<div class="container">
        <table>
                <tr>
                    <th>Companies</th>
                    <th>Devices</th>
                    <th>Vehicles</th>
                    <th>Drivers</th>
                </tr>

                     @foreach($companies as $company)
                    <tr>
                    <td>{{$company->name}}</td>
                    @endforeach

                    @foreach($devices as $device)
                    <td>{{$device->type}}</td>
                    @endforeach

                    @foreach($vehicles as $vehicle)
                    <td>{{$vehicle->license_plate}}</td>
                    @endforeach

                    @foreach($drivers as $driver)
                    <td>{{$driver->name}}</td>
                    @endforeach
                    </tr>
        </table>
    </div>

我需要表格来显示这种方式 Picture of table that I need

我为foreach循环和表尝试了几种不同的变体，但是我没有更多的想法了。

您可以一次foreach

@foreach($companies as $key => $company)
    <tr>
        <td>{{$company->name}}</td>
        <td>{{$devices[$key]->type}}</td>
        <td>{{$vehicles[$key]->license_plate}}</td>
        <td>{{$drivers[$key]->name}}</td>
    </tr>
@endforeach

这只能通过在新控制器中创建数组来完成。

class WelcomeController extends Controller {
public function index(Request $request) {

    $items = [];
    foreach (Companies::all() as $comp) $items[]['company']=$comp;
    foreach (Device::all() as $index => $dev){
        if($items[$index]) $items[$index]['device']=$dev;
        else $items[]['device']=$dev;
    }

    foreach (Vehicle::all() as $index => $veh){
        if($items[$index]) $items[$index]['vehicle']=$veh;
        else $items[]['vehicle']=$veh;
    }

    foreach (Driver::all() as $index => $dr){
        if($items[$index]) $items[$index]['driver']=$dr;
        else $items[]['driver']=$dr;
    }



    return view('/welcome', ['items'=>$items]);
}

在刀片的表主体中，我这样写：

<tbody>

                @foreach($items as $company)
                <tr>
                    <td>{{isset($company['company'])?$company['company']->name:''}}</td>
                    <td>{{isset($company['device'])?$company['device']->type:''}}</td>
                    <td>{{isset($company['vehicle'])?$company['vehicle']->type:''}}</td>
                    <td>{{isset($company['driver'])?$company['driver']->name:''}}</td>

                </tr>
                @endforeach

            </tbody>

一个刀片中有多个foreach循环
