问题描述
我有一个简单的问题.
我有一个带有字段的表单,例如:
$builder
->add('x')
->add('y')
->add('z')
;
在我的树枝文件中,我使用了多个块,并且我想停止渲染字段...我查看了b.html.twig文件!
In my twig files i used multiple blocks and i want to stop render fields...I view the b.html.twig file!
a.html.twig
{% block body %}
{% block form %}
{{ form_widget(form) }}
{% endblock form %}
{% endblock body %}
b.html.twig
{% block form %}
{{ form.x.set('rendered', true) | default() }}
{{ parent() }}
{% endblock form %}
如果我删除"default()",则会收到错误消息,表明该对象无法转换为字符串.实际上,该表单会呈现所有字段...包括x字段.但是他们不应该渲染x字段...
If i remove the "default()" i get the error, that the object cant be converted to a string.And actually the form renders all fields... Inclusive the x field. But they shouldnt render the x field...
提前谢谢!
推荐答案
我在这里错过了这个问题吗?如果您想将一个字段设置为呈现状态,即使不是,那么简单的调用是:
Am I missing the question here? If you want to set a field as rendered even though it is not the simple call is:
{% do form.x.setRendered %}
如果我误解了,我道歉.
If I misunderstood, my apologies.
