在 Laravel-Excel 3.0 中设置活动 Sheet

Question

我使用以前版本的 Laravel-Excel to export data and in the past I've been able to use $sheets->setActiveSheetIndex(0)->download('xls'); (link to PHPSpreadsheet documentation) 来设置用户打开文件时的活动选项卡。

在 3.0 版本中，我不知道该把它放在哪里。如果我不尝试设置活动 sheet，文件就会下载，因此其余代码有效。我已经尝试将它添加到导出控制器中，如下所示，但它会抛出错误 Call to undefined method App\Exports\TechMatrixExport::setActiveSheetIndex()。在下面的示例中，我希望 TechnologiesSheet 在用户打开文件时处于活动状态。

namespace App\Exports;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;


class TechMatrixExport implements WithMultipleSheets
{
    use Exportable;

    public function sheets(): array
    {

        $sheets = [];        
        $sheets[] = new TechnologiesSheet();
        $sheets[] = new NotesSheet();
        $sheets[] = new InputsSheet();
        $sheets[] = new ReferencesSheet();

        return $sheets;
    }
}

控制器：

public function __construct(\Maatwebsite\Excel\Excel $excel)
{
    $this->excel = $excel;
}

public function exportAll() 
{
    return (new TechMatrixExport)->setActiveSheetIndex(0)->download('tech_matrix.xlsx');
}

->setActiveSheetIndex(0); 属于哪里？

您应该使用 BeforeWriting (https://laravel-excel.maatwebsite.nl/3.0/exports/extending.html#available-events) 来设置 ActiveSheetIndex。

我在你的代码中添加了 RegistersEventListeners，我在我的项目中以这种方式工作，如果这对你有用，请告诉我。

namespace App\Exports;

use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithMultipleSheets;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Concerns\RegistersEventListeners;
use Maatwebsite\Excel\Events\BeforeExport;
use Maatwebsite\Excel\Events\BeforeWriting;

class TechMatrixExport implements WithMultipleSheets, WithEvents
{
  use Exportable, RegistersEventListeners;

  public function registerEvents(): array
  {
    return [
      // Handle by a closure.
      BeforeExport::class => function(BeforeExport $event) {
          $event->writer->getProperties()->setCreator('You')->setTitle("Title");
      },
      BeforeWriting::class => function(BeforeWriting $event) {
          $event->writer->setActiveSheetIndex(0);
      },
    ];
  }

  public function sheets(): array
  {
    $sheets = [];        
    $sheets[] = new TechnologiesSheet();
    $sheets[] = new NotesSheet();
    $sheets[] = new InputsSheet();
    $sheets[] = new ReferencesSheet();

    return $sheets;
  }
}
