Laravel 发送附有多个 PDF 的电子邮件

如何解决Laravel 发送附有多个 PDF 的电子邮件

我正在发送一封附有多个 PDF 的电子邮件。我的发票控制器中有一段代码，它发送附有单个 pdf 的电子邮件。

for ($i = 0; $i < sizeof($email); $i++) { // send to multiple emails
            if ($email[$i] != ";" && $email[$i] != null && $email[$i] != "") {
                $data['email'] = $email[$i];
                try {
                    Mail::send(['html'=>'invoice-attachment'],$data,function($message)use($data,$pdf,$filename) {
                        $message->from($data['from'])
                        ->to($data["email"])
                        ->subject($data["subject"])
                        ->attachData($pdf->output(),"$filename");
                    });
                } catch(JWTException $exception){
                    $this->serverstatuscode = "0";
                    $this->serverstatusdes = $exception->getMessage();
                }
    
                if (Mail::failures()) { // if email fail
                    $error++;
                }
            }
        }

        if($error > 0) {
            return redirect()->back()->with([
                'message'    => "Error sending reminder email to client",'alert-type' => 'error',]);
        } else {
            return redirect()->back()->with([
                'message'    => "Reminder emails sent to client successfully",'alert-type' => 'success',]);
        }

生成PDF（与Voyager相关）的代码如下：

            if (strlen($dataType->model_name) != 0) { // Model name => App\WhmcsClient
                $model = app($dataType->model_name);
    
                // Use withTrashed() if model uses SoftDeletes and if toggle is selected
                if ($model && in_array(SoftDeletes::class,class_uses($model))) {
                    $model = $model->withTrashed();
                }
                if ($dataType->scope && $dataType->scope != '' && method_exists($model,'scope'.ucfirst($dataType->scope))) {
                    $model = $model->{$dataType->scope}();
                }
                $dataTypeContent = call_user_func([$model,'findOrFail'],$id);
                if ($dataTypeContent->deleted_at) {
                    $isSoftDeleted = true;
                }
            } else {
                // If Model doest exist,get data from table name
                $dataTypeContent = DB::table($dataType->name)->where('id',$id)->first();
            }
    
            // Replace relationships' keys for labels and create READ links if a slug is provided.
            $dataTypeContent = $this->resolveRelations($dataTypeContent,$dataType,true);
    
            // If a column has a relationship associated with it,we do not want to show that field
            $this->removeRelationshipField($dataType,'read');
    
            // Check permission
            $this->authorize('read',$dataTypeContent);
    
            // Check if BREAD is Translatable
            $isModelTranslatable = is_bread_translatable($dataTypeContent);
    
            $view = 'voyager::bread.read';
    
            if (view()->exists("voyager::$slug.read")) {
                $view = "voyager::$slug.read";
            }

如您所见，我只能发送附有单个 PDF 的电子邮件。如何通过修改我的代码来发送附有多个 PDF 的电子邮件？
