如何在 maatwebsite/excel 中从 2.x 升级到 3.x？

Question

我将我的应用程序迁移到 Laravel 5.7。在 composer.json 中安装软件包时，我从“maatwebsite/excel:~2.1.0”升级到“maatwebsite/excel”：“^3.1”。所以现在我的导出功能不起作用不再。我尝试按照https://docs.laravel-excel.com/3.1 中的升级进行操作，但对我不起作用。这是曾经在旧版本中工作的旧代码：

$claim = Claim::all();
$count = Claim::count();
$name = 'Liste réclamations '.date('d-m-Y H-i');
    Excel::create($name, function($excel) use($claim, $count) {

        $excel->sheet('Sheetname', function($sheet) use($claim, $count) {

            $i = 2;
            $rows = $count;
            $rows++;

            $sheet->setHeight(1, 25);
            $sheet->setAutoSize(true);
            $sheet->setBorder('A1:AH'.$rows, 'thin');

            $sheet->row(1, array(

                'Utilisateur',
                'Référence',
                'Infraction',
                'Groupe oiseaux',
                "Type de braconnage",
                "Type de l'espèce",
                "Nom de l'espèce",
                "Autre info de l'espèce",
                "Description de l'oiseau",

我已经重新创建了您的项目示例来完成这项工作：按照我所做的步骤完全实现：

1. 安装包：

composer require maatwebsite/excel

2. 现在运行以下命令：

php artisan make:export ClaimsExport --model=Claim

3. 这将创建app/Exports/ClaimsExport.php。粘贴以下代码：

<?php

namespace App\Exports;

use App\Claim;
use Maatwebsite\Excel\Events\AfterSheet;
use PhpOffice\PhpSpreadsheet\Style\Fill;
use Maatwebsite\Excel\Concerns\WithEvents;
use PhpOffice\PhpSpreadsheet\Style\Border;
use Maatwebsite\Excel\Concerns\WithMapping;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\ShouldAutoSize;
use Maatwebsite\Excel\Concerns\FromCollection;

class ClaimsExport implements FromCollection, WithHeadings, ShouldAutoSize, WithEvents, WithMapping
{
    //
    public function headings(): array
    {
        return [
            'Utilisateur',
            'Référence',
            'Infraction',
            'Groupe oiseaux',
            "Type de braconnage",
            "Type de l'espèce",
            "Nom de l'espèce",
            "Autre info de l'espèce",
            "Description de l'oiseau",
            "Le nombre d'oiseau",
            "Le nombre d'oiseaux mis en vente",
            "Prix de vente",
            "Lieu de la vente",
            "Nombre d'oiseaux détenus",

            "Autre objectif",

            "Latitude",
            "Longitude",
            "Date de l'infraction",
            "L'heure de l'infraction",
            "Description de l'infraction",
            "Etat",

        ];
    }

    //

        return Claim::with('user')->get();
    }

    //
    public function map($claim): array

        // TODO: following two lines are fake data for visualisation
        $braconnage = 'A|B';
        $contact = 'C|D';

        // TODO: Implement this

        if (isset($braconnage_link)) {
            foreach ($braconnage_link as $key => $value) {
                $braconnage = $braconnage . $value->claimbrac['title_fr'] . ' | ';
            }
        }

        if (isset($contact_link)) {

            }
        }

        return [
            $claim->user['name'],
            $claim->reference,
            $claim->name_infraction,
            $claim->group_oiseau,

            $claim->indication_etat_oiseau_other,
            $claim->lieu_infraction,
            $claim->governorate['title_fr'],
            $claim->latitude,
            $claim->longitude,
            $claim->date_infraction,
            $claim->time_infraction,
            $claim->description_infraction,
            $claim->etat,
            $claim->created_at,
        ];
    }

    //
    public function registerEvents(): array
    {
        return [
            AfterSheet::class => function (AfterSheet $event) {
                $styleArray = [
                    'font' => [
                        'bold' => true,
                        'size' => 12,
                        'name' => 'Calibri',
                        'color' => ['argb' => 'FFFFFFFF'],
                    ],
                    'borders' => [
                        'outline' => [
                            'borderStyle' => Border::BORDER_THIN,
                        ],
                    ],
                    'fill' => [
                        'fillType' => Fill::FILL_SOLID,
                        'startColor' => [
                            'argb' => 'FF1E86CF',
                        ],
                    ],
                ];

                $event->sheet->getDelegate()->getStyle('A1:AG1')->applyFromArray($styleArray);
            },
        ];
    }
}

• 你会在那里找到 TODO。尝试自己实现。我不知道Claimtypelink和Claimcontactlink 做什么。

  4. 现在在控制器内部添加以下方法：

public function export()
{
    $name = 'Liste réclamations ' . date('d-m-Y H-i') . '.xlsx';

    return Excel::download(new ClaimsExport, $name);
}

并将其添加到该文件的顶部：

use App\Exports\ClaimsExport;
use Maatwebsite\Excel\Facades\Excel;

5. 内部路线添加：

Route::get('claims/export', 'ClaimController@export')->name('export');

你很高兴去。
