我试图使用L5分页,一切看起来很好,直到我点击第二页链接.当我点击它我得到这个错误：

Laravel 5 Pagination undefined variable vehicles in view

调节器

public function search() {
    $vehicle = Vehicle::with('representive','seller','buyer','whoUpdated')->orderBy('created_at','desc')->first();;

    $previous = Vehicle::where('id','<',$vehicle->id)->max('id');

    $next = Vehicle::where('id','>',$vehicle->id)->min('id');

    $first = Vehicle::orderBy('created_at','asc')->first();
    $last = Vehicle::orderBy('created_at','desc')->first();


    //passing rapyd components
    $rapydProcess = new RapydController();
    $searchFilter = $rapydProcess->createSearchFilter();
    $searchGrid = $rapydProcess->createVehicleDataGrid($searchFilter);
    $vehicleTrackFilter = $rapydProcess->createVehicleTrackFilter();
    $vehicleTrackDataGrid = $rapydProcess->createVehicleTrackDataGrid($vehicleTrackFilter);
    //$statisticsDataGrid = $rapydProcess->statisticsDataGrid();

    //passing select box contents to view
    $clients = Client::lists('full_name','id');

    $sections = Section::lists('section_name','id');
    $brands = Brand::lists('brand_name','id');
    $paymentTypes = PaymentType::lists('payment_type','id');
    $searchOptions = StatisticsSearchOptions::lists('option_name','slug');

    $option1 = Request::get('option1');

    if (isset($option1_value)) {
        $actual_option1 = '';
        foreach ($option1_value as $value) {
            if ($value != '') {
                $actual_option1 = $value;
            }
        }
    }

    if (isset($option1_value)) {
        $actual_option2 = '';
        foreach ($option2_value as $value) {
            if ($value != '') {
                $actual_option2 = $value;
            }
        }
    }

    if($condition == 'no'){
        $vehicles = Vehicle::with('brand','section','representive','buyingPaymentType','sellingPaymentType')->where($option1,$actual_option1)->paginate(2);
        //return $vehicle;
    }
    if($condition == 'or'){
        $vehicles = Vehicle::with('brand',$actual_option1)->orWhere($option2,$actual_option2)->paginate(2);

    if($condition == 'and'){
        $vehicles = Vehicle::with('brand',$actual_option1)->where($option2,$actual_option2)->paginate(2);

    return view('pages.aracislemler',compact('vehicles','condition','option1','option2','actual_option1','actual_option2','vehicle','previous','next','first','last','searchFilter','searchGrid','vehicleTrackFilter','vehicleTrackDataGrid','statisticsDataGrid','vehicleTypes','sections','brands','clients','paymentTypes','searchOptions'));

视图

@if(isset($vehicles))
    @foreach($vehicles as $vehicle)
        <tr>
            <td style="padding: 15px;">{{ $vehicle->id }}</td>
            <td style="padding: 15px;">{{ $vehicle->brand_id }}</td>
            <td style="padding: 15px;">{{ $vehicle->model }}</td>
            <td style="padding: 15px;">{{ $vehicle->type_id }}</td>
            <td style="padding: 15px;">{{ $vehicle->licenseplate }}</td>
            <td style="padding: 15px;">{{ $vehicle->representive_client_id }}</td>
            <td style="padding: 15px;">{{ $vehicle->buyer_client_id }}</td>
            <td style="padding: 15px;">{{ $vehicle->seller_client_id }}</td>
            <td style="padding: 15px;">{{ $vehicle->debit_situation }}</td>
            <td style="padding: 15px;">{{ $vehicle->partner_situation }}</td>
            <td style="padding: 15px;"><a href="{{ URL::to( 'pages/vehicles?show=' . $vehicle -> id ) }}">Git</a></td>
        </tr>
    @endforeach
@endif

{!! $vehicles->appends(['condition' => 'condition','option1' => 'option1','option2' => 'option2','actual_option1' => 'actual_option1','actual_option2' => 'actual_option2'])->render()!!}

作为一个L5新手,我不知道该怎么办,我该如何解决这个问题呢？
任何帮助,将不胜感激.

解决方法

你没有将你的$条件追加到分页中,所以它就丢失了.在返回View之前的if语句中(在Controller中),只有在满足$condition时才设置$vehicles变量(没有回退),所以它不会将$vehicles传递给视图.设置回退是明智的,如果实际上没有条件,请将$vehicles变量设置为某个值,否则会导致您遇到的错误.

请注意,您还必须将其传递给您的视图！ (你目前没有这样做)

在你的视图中尝试这样的事情：

{!! $vehicles->appends(['condition' => $condition])->render()!!}

并将其添加到您的控制器：

return view('pages.aracislemler','condition'...

编辑(正如评论和@HieuLu所解释的那样:(例如,您可能必须根据需要更改最后的其他内容)

if($condition == 'no'){
    $vehicles = Vehicle::with('brand',$actual_option1)->paginate(2);
    //return $vehicle;
}
elseif($condition == 'or'){
    $vehicles =             Vehicle::with('brand',$actual_option2)->paginate(2);
}
elseif($condition == 'and'){
    $vehicles = Vehicle::with('brand',$actual_option2)->paginate(2);
} 
else {
    $vehicles = Vehicle::with('brand','sellingPaymentType')->paginate(2);
}
