spl_object_hash() 尝试提交我的 Symfony 表单时出错？

Question

我想提交 2 个表单，Article 和 groupeAuteur，当我点击提交时我收到了这个错误。

我正在尝试嵌入表单，但在提交时出现此错误：

Warning: spl_object_hash() expects parameter 1 to be object, string given

Answer 1

*我通过添加初始化 articleType 中的 Collection auteurs 解决了这个问题这行 *

       $builder->addEventListener(FormEvents::PRE_SET_DATA, function (FormEvent $event) {
            $event->getData()->addAuteur(new GroupeAuteur());
        });
