【问题描述】：
我正在尝试使用 PHP 7、Laravel 5.8、Maatwebsite Excel 3.1 导出到 excel。我成功显示在视图刀片上并执行了过滤器。
型号：
use App\UserResponse;
控制器
public function userresponseReport(Request $request,$export=false)
{
$data['title'] = 'User Response';
$userresponses = DB::table('user_response as g')
->select(
//DB::raw('DATE(g.created_at) as created_date'),
DB::raw('g.created_at as created_date'),
'g.msisdn',
'g.game_code',
'g.answer',
'g.answer_code',
'g.Amount_charged',
'g.payment_ref',
'g.status',
'g.user_channel'
)
->orderByRaw('g.created_at DESC');
$start_date = $request->start_date;
$end_date = $request->end_date;
$render=[];
if(isset($request->start_date) && isset($request->end_date))
{
$userresponses = $userresponses->whereBetween('created_at',[$start_date.' 00:00:00',$end_date.' 23:59:59']);
$render['start_date'] = $request->start_date;
$render['end_date'] = $request->end_date;
} elseif(isset($request->start_date)) {
$userresponses = $userresponses->where('created_at',$request->start_date);
$render['start_date'] = $request->start_date;
}
if(isset($request->msisdn))
{
$userresponses = $userresponses->where('msisdn','like','%'.$request->msisdn.'%');
$render['msisdn'] = $request->msisdn;
}
if(isset($request->game_code))
{
$userresponses = $userresponses->where('game_code','like','%'.$request->game_code.'%');
$render['game_code'] = $request->game_code;
}
if(isset($request->user_channel))
{
$userresponses = $userresponses->where('user_channel','like','%'.$request->user_channel.'%');
$render['user_channel'] = $request->user_channel;
}
if(!empty($export))
{
return Excel::download(new UserresponseExport($userresponses->get()), 'userresponse.xlsx');
}
$userresponses = $userresponses->orderBy('created_at','DESC');
$userresponses = $userresponses->paginate(15);
$userresponses = $userresponses->appends($render);
$data['userresponses'] = $userresponses;
return view('report.userresponseReport',$data);
}
然后，视图刀片：
userresponseReport.blade.php
<div class="row" style="margin-bottom: 10px">
{{ Form::model(request(),['method'=>'get']) }}
<div class="col-sm-2">
{{ Form::text('msisdn',null,['class'=>'form-control','placeholder'=>'MSISDN']) }}
</div>
<div class="col-sm-2">
{{ Form::text('game_code',null,['class'=>'form-control','placeholder'=>'Game Code']) }}
</div>
<div class="col-sm-2">
{{ Form::text('user_channel',null,['class'=>'form-control','placeholder'=>'Channel']) }}
</div>
<div class="col-sm-2">
{{ Form::date('start_date',null,['class'=>'form-control','placeholder'=>'Date']) }}
</div>
<div class="col-sm-2">
{{ Form::date('end_date',null,['class'=>'form-control','placeholder'=>'Date']) }}
</div>
<div class="col-xs-2">
{{ Form::submit('Search',['class'=>'btn btn-warning']) }}
<a href="{{ route('userresponseReport',['export']) }}" class="btn btn-primary"><i class="fa fa-file-excel-o"></i> Excel</a>
</div>
{{ Form::close() }}
</div>
<div class="box box-primary">
<div class="box-header with-border">
<table class="table table-bordered table-hover table-striped table-condesed" id="commenter_info_table">
<caption></caption>
<thead>
<tr>
<td>#</td>
<td>Date</td>
<td>MSISDN</td>
<td>Game Code</td>
<td>Game Name</td>
<td>Answer</td>
<td>Channel</td>
</tr>
</thead>
<tbody>
@foreach($userresponses as $key => $userresponse)
<tr>
<td>{{ ++$key }}</td>
<!-- <td>{{ $userresponse->created_date }}</td>-->
<td>{{ date('Y-m-d h:i:s A', strtotime($userresponse->created_date)) }}</td>
<td>{{ $userresponse->msisdn }}</td>
<td>{{ $userresponse->game_code }}</td>
<td>
@if($userresponse->game_code=='101')
Trivia
@elseif($userresponse->game_code=='102')
Predict and Win
@elseif($userresponse->game_code=='103')
Party With the BBN
@elseif($userresponse->game_code=='104')
Grand Prize
@elseif($userresponse->game_code=='105')
Happy Hour
@elseif($userresponse->game_code=='106')
Power Boost
@endif
</td>
<td>{{ $userresponse->answer }}</td>
<td>{{ $userresponse->user_channel }}</td>
</tr>
@endforeach
<tr>
<td colspan="14">
{{ $userresponses->links() }}
</td>
</tr>
</tbody>
</table>
然后是导出
UserresponseExport
class UserresponseExport implements FromView, WithHeadings, ShouldAutoSize, WithEvents, WithMapping
{
protected $userresponses;
public function __construct($userresponses = null)
{
$this->userresponses = $userresponses;
}
public function view(): View
{
return view('report.userresponseReport', [
'userresponses' => $this->userresponses ?: DB::table('user_response as g')
->select(
DB::raw('g.created_at as created_date'),
'g.msisdn',
'g.game_code',
'g.answer',
'g.answer_code',
'g.Amount_charged',
'g.payment_ref',
'g.status',
'g.user_channel'
)
->orderByRaw('g.created_at DESC')
]);
}
private $headings = [
'Date Created',
'MSISDN',
'game_code',
'Answer',
'Channel'
];
public function headings(): array
{
return $this->headings;
}
public function registerEvents(): array
{
return [
AfterSheet::class => function(AfterSheet $event) {
$cellRange = 'A1:E1'; // All headers
$event->sheet->getDelegate()->getStyle($cellRange)->getFont()->setSize(14);
},
];
}
}
路线
Route::get('/report/userresponse-report/{export?}', ['as' => 'userresponseReport', 'uses' => 'ReportController@userresponseReport']);
在视图刀片上，当我单击搜索时，一切正常。但是当我点击导出时，我得到了这个错误：
错误异常 (E_ERROR) 方法 Illuminate\Support\Collection::links 不存在。 （查看：C:\xampp\htdocs\bbnaijareport\resources\views\report\userresponseReport.blade.php） 以前的例外 方法 Illuminate\Support\Collection::links 不存在。 (0)
我该如何解决这个问题？
