带有实体信息的 Symfony2 小部件数据

Question

这个项目是由另一个开发人员开始的，现在有一个功能可以在表单中插入来自数据库的数据，但是在日期输入中我无法用数据库值更新输入..

我的数据小部件表单有问题。我的小部件有以下代码：

                ->add('borndate', 'birthday', array(
                'widget' => 'choice',
                'attr'  => array(
                    'class' => 'form-control'
                ),
                'label' => 'user.birthday.label',
                'input' => 'string',
                'format' => 'dd.MM.yyyy',
                'data' => '1950-01-01'
            ))

我想在 DB 上获得我的实体的值，在另一个小部件中，例如名称：

->add('name','text',array(
'label'=>'user.name.label',
'required'=>true
 ))

我已经收到这个功能，但不是最新的.. 我该怎么办？？

Answer 1

那么，如果我在尝试更新数据库上的日期值时理解正确的话，您总是会得到原始值吗？

问题是实体管理器像处理对象一样处理 DateTime。如果您想更新字段中的日期，您需要创建一个新的 DateTime 对象来更新日期。

例如，在您处理 $form->isValid() 的控制器中，您必须做这样的事情 $person->setBorndate(new \DateTime([Value for the new Date]));。

现在您所要做的就是获取日期的新值。在变量 $request 或 $form 中你应该能够找到它。
