我想在 Laravel 的一个 delivery_notes_id 中插入更多项目。但我收到错误“数组到字符串的转换”。当我用 $lastid 删除代码时，没有错误。你能帮助我吗？

$data=$request->all();
        $lastid=delivery_note::create($data)->id;
        $delivery_note->datum = $data['datum'];
        $delivery_note->customer_id = $data['customer'];

        if(count($data['produkt']) > 0)
        {
            $data2=[];
            foreach($data['produkt'] as $item => $value)
                array_push($data2, [
                    'delivery_notes_id'=>$lastid,
                    'menge'=>$request['menge'][$item],
                    'einheit'=>$request['einheit'][$item],
                    'product_id'=>$request['produkt'][$item],
                ]);
                Items::insert($data2);
            }
       return $this->index()->with([
        'meldung_success' => 'Lieferschein wurde erstellt!'
    ]);
}

这是 HTML 代码。我已经尝试过以下教程https://tsdurjoy.blogspot.com/2019/01/laravel-multiple-data-insert-into_20.html

试试这个：

$data=$request->all();
    $lastid=delivery_note::create($data)->id;
    $delivery_note->datum = $data['datum'];
    $delivery_note->customer_id = $data['customer'];

    if(count($data['produkt']) > 0)
    {

        foreach($requsest->get('produkt') as $item => $value){
            $data = new yourModelName();
            $data->delivery_notes_id=$lastid;
            $data->menge=$request->menge[$item];
            $data->einheit=$request->einheit[$item];
            $data->product_id=$request->produkt[$item]
           $data->save();
           
        }
    }
    return $this->index()->with([
        'meldung_success' => 'Lieferschein wurde erstellt!'
    ]);
}
