symfony表单中生日的/ DateTime字段

I need to retrieve the birthday of a student from the database and set it as the birthday of a student entity. Then I need to load that data to a form.

我需要从数据库中检索学生的生日并将其设置为学生实体的生日。然后我需要将该数据加载到表单。

$birth_day = strtotime($student_[0]['birthday']);
$birth__day = date('Y-m-d H:i:s',$birth_day); 
$student->setBirthday($birth__day);

And in the form builder I have used the below code

在表单构建器中，我使用了以下代码

add('birthday', 'birthday',array(
            'data' => new \DateTime(),'placeholder'=>'-SELECT-'))

Instead of the birthday that particular student, it shows the today's date.

它显示了今天的日期，而不是特定学生的生日。

Can someone please explain what should I do to load the birthday instead of the today's date. Thankyou in advance.

有人可以解释我应该怎么做加载生日而不是今天的日期。先谢谢你。

When you use the 'data' option, you are setting the default value for the field so in your example you are setting it to a new Datetime (today).

当您使用'data'选项时，您正在设置字段的默认值，因此在您的示例中，您将其设置为新的Datetime（今天）。

Here is the symfony doc page about it http://symfony.com/doc/current/reference/forms/types/form.html#data

这是关于它的symfony doc页面http://symfony.com/doc/current/reference/forms/types/form.html#data

Like @abdiel suggested, remove the data part.

像@abdiel建议的那样，删除数据部分。
