我在视图中有数据

<div class="box-body table-responsive no-padding">

                <div id="users-table-wrapper">
                    <table id="users_table" class="table table-hover table-striped">
                        <tbody>
                            <tr>
                               <th>@lang('app.soldto')</th>
                               <th>@lang('app.soldby')</th>
                                <th>@lang('app.network')</th>
                               <th>@lang('app.plan')</th>
                               <th>@lang('app.sales_date')</th>
                           </tr>
                           @if (count($sales))
                           @foreach ($sales as $sale)
                           <tr>
                            <td>{{ $sale->soldto ?: trans('app.n_a') }}</td>
                            <td>{{ $sale->first_name . ' ' . $sale->last_name }}</td>

                            <td>{{ $sale->name }}</td>
                            <td>{{ $sale->plan }}</td>
                             <td>{{ $sale->salesdate }}</td>

                        </tr>
                        @endforeach
                        @else
                        <tr>
                            <td colspan="6"><em>@lang('app.no_records_found')</em></td>
                        </tr>
                        @endif
                    </tbody>
                </table>
                {!! $sales->render() !!}
            </div>
        </div>
    </div>

我使用分页来显示每页10行。如下所示

我想将所有这些数据下载到CSV。不再运行db查询。

Answer 1

Datatable本身提供了导出csv，xls，pdf等的按钮。这是代码

$('#example').DataTable( {
    dom: 'Bfrtlp',
    buttons: ['csv','pdf']
} );

＆＃39;＃示例＆＃39;是你的表的id

您可以使用以下工作代码：

public static function exportCsv()
{

    header('Content-Type: text/csv; charset=utf-8');
    header('Content-Disposition: attachment; filename=data.csv');

    $rows = DB::select( DB::raw("select * from users
                ;") );

    $rows = json_decode(json_encode((array) $rows), true);
    //\Log::info('query'.print_r($rows,true));
     ob_end_clean();

    $out = fopen('php://output', 'w');
    foreach($rows as $key=>$values)
    {   
        $arr = [];
        foreach ($values as $key=>$value) {
            array_push($arr, $key);
        }
        $line = $arr;
        fputcsv($out, $line);
        break;
    }

    //fputcsv($out, array('Registration', 'Name', 'Checkin Time'));
    foreach($rows as $lines)
    {
        $line = $lines;
        fputcsv($out, $line);
    }
    die;
    fclose($out);
}
