我将应用程序迁移到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再起作用。我尝试遵循https://docs.laravel-excel.com/3.1中的升级，但对我不起作用。这是以前在旧版本中可用的旧代码：
$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",

))->cells('A1:AH1', function($cells) {
$cells->setBackground('#1E86CF');
$cells->setFont(array(
'family' => 'Calibri',
'size' => '12',
'bold' => true
));
$cells->setFontColor('#ffffff');
});
foreach ($claim as $key => $claim) {
$braconnage = '';
$contact= '' ;
$braconnage_link = Claimtypelink::where('claim_id',$claim->id)->with('claimbrac')->get();
$contact_link = Claimcontactlink::where('claim_id',$claim->id)->with('claimcontactaut')->get();
if(isset($braconnage_link)){
foreach ($braconnage_link as $key => $value) {
$braconnage = $braconnage.$value->claimbrac['title_fr'].' | ';
}
}
if(isset($contact_link)){
foreach ($contact_link as $key => $value) {

我已经重新创建了您的项目示例以完成这项工作： 按照与我完全一样的步骤实施：
composer require maatwebsite/excel
php artisan make:export ClaimsExport --model=Claim
<?php

use App\Claim;
use Maatwebsite\Excel\Events\AfterSheet;

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

}
//

{

}
//

if (isset($braconnage_link)) {
foreach ($braconnage_link as $key => $value) {
$braconnage = $braconnage . $value->claimbrac['title_fr'] . ' | ';
}
}
if (isset($contact_link)) {
foreach ($contact_link as $key => $value) {
$contact = $contact . $value->claimcontactaut['title_fr'] . ' | ';
}
}
return [
$claim->user['name'],
$claim->reference,
$claim->name_infraction,
$claim->group_oiseau,
$braconnage,
$claim->type_espece,
$claim->bird['title_fr'],
$claim->type_espece_other,
$claim->description_oiseau,
$claim->num_espece,
$claim->num_espece_vente,
$claim->prix_vente,
$claim->lieu_vente,
$claim->num_espece_detenu,
$claim->interdiction_chasse,
$claim->presence_ordre,

}
//
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);
},
];
}
}
您将在此处找到待办事项。尝试自己实现。我不知道 Claimtypelink 和 Claimcontactlink做什么。
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;
Route::get('claims/export', 'ClaimController@export')->name('export');
你很好。
