Symfony2, How to make a form label class/attr different than its input?
提问by pmoubed
I would like to build a form with label and inputs, but the class of them should be different. Code below creates the label for the input with same attr:
我想用标签和输入构建一个表单，但它们的类应该不同。下面的代码为具有相同属性的输入创建标签：
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('hours', null ,
array('attr'=>
array(
'placeholder'=>'Working Hours',
'class'=>'ui-spinner-box') ) )
}
In my code above the ui-spinner-boxwill be outputted for both label and input. It will even put placeholder for its label.
在我上面的代码中，ui-spinner-box将输出标签和输入。它甚至会为其标签放置占位符。
So how to make it create attrfor label separately so I can output something like below :
那么如何attr单独为标签创建它，以便我可以输出如下内容：
<label class="MYCLASSFOR_LABEL" for="input_id">Hours</label>
<input class="MYCLASSFOR_INPUTS" type="text" id="input_id" name="" value="" >

As mentioned in the documentation:
如文档中所述：
- attr : A key-value array that will be rendered as HTML attributes on the field
- label_attr: A key-value array that will be rendered as HTML attributes on the label
- attr : 将在字段上呈现为 HTML 属性的键值数组
- label_attr：一个键值数组，将在标签上呈现为 HTML 属性
You can set those attributes in twig template or in form builder:
您可以在树枝模板或表单构建器中设置这些属性：
Twig template:
树枝模板：
for symfony 2.1 and newer use:
{{ form_label(form.hours, null, {'label_attr': {'class': 'foo'}}) }}in the legacy symfony 2.0 it used to be
{{ form_label(form.hours, { 'label_attr': {'class': 'MYCLASSFOR_LABEL'} }) }} {{ form_widget(form.hours, { 'attr': {'class': 'MYCLASSFOR_INPUTS'} }) }}
对于 symfony 2.1 和更新的使用：
{{ form_label(form.hours, null, {'label_attr': {'class': 'foo'}}) }}在旧版 symfony 2.0 中，它曾经是
{{ form_label(form.hours, { 'label_attr': {'class': 'MYCLASSFOR_LABEL'} }) }} {{ form_widget(form.hours, { 'attr': {'class': 'MYCLASSFOR_INPUTS'} }) }}
Form builder
表单生成器
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('hours', null, array(
'label_attr' => array('class' => 'MYCLASSFOR_LABEL'),
'attr' => array('class' => 'MYCLASSFOR_INPUTS'),
));
}

This may be new, but there's an easy way to do this now:
这可能是新的，但现在有一种简单的方法可以做到这一点：
$builder
->add('hours', null , array(
'attr'=>
array(
'placeholder'=>'Working Hours',
'class'=>'MYCLASSFOR_INPUTS')
) ,
'label_attr' => array(
'class' => 'MYCLASSFOR_LABEL'
)
);
The option you're looking for is label_attr.
您正在寻找的选项是label_attr。

This works for me in Symfony 2.3:
这在 Symfony 2.3 中对我有用：
{{ form_row(form.hours, { 'label': 'Hours:'
,'label_attr': {'class': 'MYCLASSFOR_LABEL'}
,'attr': {'class': 'MYCLASSFOR_INPUTS'}
}
)
}}

The above is no longer correct, at least in the context I was using it. In Symfony 2.1 the solution is:
以上不再正确，至少在我使用它的上下文中。在 Symfony 2.1 中，解决方案是：
{{ form_label(form.item, label|default(null), { 'label_attr': { 'class': 'MYCLASS' } }) }}
