Question

我正在创建一个应包含下拉列表的Excel模板。我看到它可能与phpexcel库（PHPExcel Multiple Dropdown list that dependent）。我想知道是否可以使用maatwebsite提供的laravel-excel库完成。我需要dropdown，NamedRange，datavalidation，setFormula等函数的语法。

Answer 1

maatwebite 版本 V.3.1 使用以下代码

<?php

namespace App\Exports;

use App\Models\Category;

use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Concerns\WithTitle;
use Maatwebsite\Excel\Events\AfterSheet;
use PhpOffice\PhpSpreadsheet\Cell\DataValidation;

class BulkUploadProductExport implements FromView, WithEvents , WithTitle
{
  

    public function view(): View
    {
        return view('exports', [
            'categories' => Category::all()
        ]);
    }

    public function title(): string
    {
        return 'bulkupload';
    }

    public function registerEvents(): array
    {

        //$event = $this->getEvent();
        return [
            AfterSheet::class => function (AfterSheet $event) {
               
                /** @var Sheet $sheet */
                $sheet = $event->sheet;

                /**
                 * validation for bulkuploadsheet
                 */

                $sheet->setCellValue('B5', "SELECT ITEM");
                $configs = "DUS800, DUG900+3xRRUS, DUW2100, 2xMU, SIU, DUS800+3xRRUS, DUG900+3xRRUS, DUW2100";
                $objValidation = $sheet->getCell('B5')->getDataValidation();
                $objValidation->setType(DataValidation::TYPE_LIST);
                $objValidation->setErrorStyle(DataValidation::STYLE_INFORMATION);
                $objValidation->setAllowBlank(false);
                $objValidation->setShowInputMessage(true);
                $objValidation->setShowErrorMessage(true);
                $objValidation->setShowDropDown(true);
                $objValidation->setErrorTitle('Input error');
                $objValidation->setError('Value is not in list.');
                $objValidation->setPromptTitle('Pick from list');
                $objValidation->setPrompt('Please pick a value from the drop-down list.');
                $objValidation->setFormula1('"' . $configs . '"');
              
            }
        ];
    }
}

                $objValidation = $sheet->getCell('D1')->getDataValidation();
