Symfony 4 - 处理多个相同形式的请求

Question

我正在尝试在页面上创建多个相同的表单，以便将产品和成员分配给制造商。在我的Controller中，我动态初始化一个自定义表单对象，以分隔View和Form的数据并存储一些数据。

<?php

namespace App\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;

use App\Entity\Manufacturer;
use App\Entity\User;
use App\Entity\Product;
use App\Entity\ProductCategory;

use App\Form\ManufacturerType;

            'memberforms' => $memberForms,
        ));
    }
}

错误：

当我提交表单来添加产品时，它会将项目保存在数据库中，但制造商始终是相同的：我在数据库中的第一个ID = 4 当我提交表单以向制造商添加成员时，没有任何反应。

我认为错误是当我处理请求并检查条件以查看表单是否有效时。
