How to add attributes to a label generated with Zend/Form in Zend framework 2
提问by El Dorado
I'm adding forms to my page using Zend/Form.
我正在使用 Zend/Form 向我的页面添加表单。
I'm adding elements by defining them as follows:
我通过如下定义来添加元素：
$this->add(array(
'name' => 'value',
'attributes' => array(
'type' => 'text',
'id' => 'value',
'autocomplete' => 'off',
'placeholder' => 'Cost',
),
'options' => array(
'label' => 'Cost',
),
));
As you can see there is a 'label' => 'cost' node, this generated a label to go with the input element.
正如您所看到的，有一个 'label' => 'cost' 节点，这会生成一个标签以与输入元素一起使用。
How do I add classes, attributes to this label ?
如何向该标签添加类、属性？

Please try this, i haven't tested or used this, but going by the source it should function properly:
请试试这个，我还没有测试或使用过这个，但从源头来看它应该可以正常运行：
$this->add(array(
'name' => 'value',
'attributes' => array(),
'options' => array(
'label_attributes' => array(
'class' => 'mycss classes'
),
// more options
),
));
If this does not function, please leave me a comment. If it won't function, it is not possible using this approach, since the FormLabelrestricts the validAttributesquite a bit:
如果这不起作用，请给我留言。如果它不起作用，则无法使用这种方法，因为它FormLabel限制了validAttributes很多：
protected $validTagAttributes = array(
'for' => true,
'form' => true,
);

This works well in Zend Framework 2.3 :
这在 Zend Framework 2.3 中运行良好：
$this->add(array(
'name' => 'userName',
'attributes' => array(
'type' => 'text',
'class' => 'form-control',
'placeholder' =>'Username',
),
'options' => array(
'label' => 'Username',
'label_attributes' => array('class' => 'control-label')
),
));

For programmatic approach on ZF2+ try this:
对于 ZF2+ 上的编程方法，试试这个：
$element->setOptions(array(
'label_attributes' => array(
'style' => 'color:gray;'
)
));

$element->setOptions(array('label_class' => array('class' => 'control-label')));
Produces code like this:
产生这样的代码：
<label class="control-label">
<input type="radio" name="option1" id="option1" value="1">
Option 1
</label>
<label class="control-label">
<input type="radio" name="option2" id="option2" value="2">
Option 2
</label>
I have tried this. It works in Zend Framework One.
