未在EntityType字段中设置所选选项

标签： php symfony doctrine-orm

我有一个模块，可以在其中添加眼镜，在该模块中，我有一个类来添加这些眼镜的可用品牌。

我面临的问题是，当我去编辑一些眼镜时，品牌总是将占位符显示为选定选项，而不是上传时选择的品牌。

我看过类似的问题，但是似乎没有一个答案可以解决我的问题。

这为品牌<select>

提供了以下HTML 
<select id="glasses_brand" name="glasses[brand]" required="required" class="form-control">
   <option value="" selected="selected">Kies een merk...</option>
   <option value="2">Gucci</option>
   <option value="1">Ray Ban</option>
   <option value="3">Tom Ford</option>
</select>

在这种情况下，应将“雷朋”作为选定的选项，而不是占位符。

formbuilder的转储返回以下内容：

在这里我可以看到品牌是null，这很可能会引起问题。

这是一个对我有用的简单示例。希望对您有帮助

控制器：

    /**

     */
    public function update(Request $request, Glasses $glasses)
    {

        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            return new Response(':)');
        }

        return $this->render('base.html.twig', [
            'form' => $form->createView(),

眼镜实体：

    public function setBrand(?Brand $brand): self
    {
        $this->brand = $brand;

        return $this;
    }
}

和表单类型：

class GlassesType extends AbstractType

    public function buildForm(FormBuilderInterface $builder, array $options)

        $builder

                },
