我从这里获得教程:https://laravel-excel.maatwebsite.nl/docs/3.0/export/basics
<?php
...
use App\Exports\ItemsDetailsExport;
class ItemController extends Controller
{
...
public function exportToExcel(ItemsDetailsExport $exporter, $id)
{
//dd($id); I get the result
return $exporter->download('Summary Detail.xlsx');
}
}
我的出口是这样的:
<?php
namespace App\Exports;
use App\Repositories\Backend\ItemDetailRepository;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\Exportable;
use Illuminate\Support\Facades\Input;
class ItemsDetailsExport implements FromCollection
{
use Exportable;
protected $itemDetailRepository;
public function __construct(ItemDetailRepository $itemDetailRepository)
{
$this->itemDetailRepository = $itemDetailRepository;
}
public function collection()
{
$test = Input::get('id');
dd('yeah', $test);
}
}
我想将id参数传递给导出文件。我这样尝试,但是我没有ID。 id为空
我该如何解决这个问题?

不幸的是,当您具有特定参数时,不能使用常规依赖项注入。这是您可以做的:
class ItemsDetailsExport implements FromCollection
{
use Exportable;
protected $itemDetailRepository;
protected $id;
public function __construct(ItemDetailRepository $itemDetailRepository, $id)
{
$this->itemDetailRepository = $itemDetailRepository;
$this->id = $id;
}
public function collection()
{
$test = $this->id;
dd('yeah', $test);
}
}
现在的问题是容器不知道如何解析$ id,但是有两种解决方法。
手动传递$id
:
public function exportToExcel($id)
{
$exporter = app()->makeWith(ItemsDetailsExport::class, compact('id'));
return $exporter->download('Summary Detail.xlsx');
}
路线注入:
将您的路线定义为:
Route::get('/path/to/export/{itemExport}', 'ItemController@exportToExcel');
在您的RouteServiceProvider.php
中:
public function boot() {
parent::boot();
//Bindings
Route::bind('itemExport', function ($id) { //itemExport must match the {itemExport} name in the route definition
return app()->makeWith(ItemsDetailsExport::class, compact('id'));
});
}
然后将您的路线方法简化为:
public function exportToExcel(ItemsDetailsExport $itemExport)
{
//It will be injected based on the parameter you pass to the route
return $itemExport->download('Summary Detail.xlsx');
}

为了将数据从控制器传递到 laravel excel 函数,我们可以传递和使用如下数据
例如,我们必须像2019那样传递数据年份我们将像下面那样传递
在控制器中
Excel::download(new UsersExport(2019), 'users.xlsx');
在laravel导入文件中
class UsersExport implements FromCollection {
private $year;
public function __construct(int $year)
{
$this->year = $year;
}
public function collection()
{
return Users::whereYear('created_at', $this->year)->get();
}
}
