ZF2在select表单元素中为选项添加自定义属性

Question

我想在Zend Framework 2表单中为select选项添加自定义HTML属性.

这是我的Form类中的(部分)代码:

$this->add(array(
        'name' => 'lieuRemplissage',
        'type' => 'Select',
        'attributes'    => array(
            'class'     => 'form-control',
        ),
        'options'   => array(
            'label' => _('Lieu pré-enregistré'),
        ),
    ));

我在我的控制器中填充我的选项值,如下所示:

$form = new \Vente\Form\Vente;
foreach($this->getAdminLieuDeVenteTable()->fetchAll() as $lieu) {
       $optionsLieu[$lieu->getId()] = $lieu->getNom();
    }
    $form->get('lieuRemplissage')->setValueOptions($optionsLieu);

但是现在,对于每个选项,我想为所有选择选项添加一个html属性,但每个选项的值都不同.

有没有办法在ZF2中实现这一目标？

谢谢.

Answer 1

是的,这可以通过ZF2实现

您传入选项值中的属性.值应为数组格式:

//视图中的示例:

$select=new \Zend\Form\Element\Select('test');
$select->setValueOptions(

    [

        ['attributes'=>['data-key'=>'value'],'value'=>'myValue','label'=>'myLabel']


    ]

    );

echo $this->formselect($select);

打印:

<select name="test"><option value="myValue" data-key="value">myLabel</option></select>

编辑:

您提供的属性必须是有效的HTML属性,您不能放置任何随机键/值对.例如data-*就像以下一样好:

protected $validGlobalAttributes = array(
        'accesskey'          => true,
        'class'              => true,

Answer 2

我刚刚想到这一点,并希望在这里分享,因为我在寻找同一个问题时看到了这个问题.应该使用建议的方式给出相同的结果,但直接在表单类中使用选项的属性; 如果将数据对象传递给表单构造以填充像我这样的选项,则特别有用.

$this->add(array(
    'name' => 'lieuRemplissage',
    'type' => 'Select',
    'attributes'    => array(
        'class'     => 'form-control',
    ),
    'options'   => array(
        'label' => _('Lieu pré-enregistré'),
        'value' => 123
        'attributes' => array(
            'data-key' => 'value_for_data_attribute_goes_here',
        ),
    ),
));
