Symfony2 - Twig:在下拉列表中设置默认值 [英] Symfony2 - Twig : Set the default value in the dropdownlist
问题描述
其中一个表单字段是从我的表单构建器中的实体创建的下拉列表。
我想在我的下拉列表中设置默认值,作为例如第28号。
我不知道如何在树枝上这样做。
我尝试了这个:
{{form_widget(form.type,{value:28})}}
但没有改变,我仍然有默认的firs值。
$ b $我知道我可以在FormType类中设置一个默认值,我正在创建我的表单生成器,但是我正在寻找一个twig的方式,在我看来,它比在formType类中创建对象更优雅。
确定,发现我的错误,代码应该是:
< p $ p>
{{form_widget(form.type,{value:28})}}
我忘记了id的引号。而且,还需要CTRL + F5来刷新页面并看到差异。
I have a Form in my twig template. One of the form fields is a dropdownlist that is created from an Entity in my form builder.
I would like to set the default value in my dropdown list, to be the id 28 for example.
I don't know how to do this in twig.
I tryed this:
{{ form_widget(form.type, {value: 28 } ) }}
But nothing changed, I still have the firs value that is by default.
I know that I can set a default value in the FormType class where I am creating my form builder, but I am looking for a twig way, it seems to me more elegant than to create the object in the formType class.
Ok, found my mistake, the code should be:
{{ form_widget(form.type, {value: "28" } ) }}
I forgot the quotes for the id. And also, there is a need to CTRL + F5 to refresh the page and see the difference.
