ZF2 - 控制/自定义单个收音机/复选框

Question

I'm attempting to add data- values on radio buttons within ZF2. Is it possible to control each of the inputs specified with value_options?

A typical radio button added to a form:

$this->add(array(
    'type'  => 'radio',
    'name'  => 'duration',
    'options' => array(
        'value_options' => array(
            'daily' => 'Daily',
            'weekly' => 'Weekly',
            'monthly' => 'Monthly',
        ),
    ),
));  

Ultimately, I would like something like the following, so I can specify individual parameters/options for each radio item:

$this->add(array(
    'type'  => 'radio',
    'name'  => 'duration',
    'options' => array(
        'value_options' => array(
            array(
                'attributes' => array(
                    'value' => 'daily',
                    'data-item' => 'apple'
                ),
                'options' => array(
                    'label' => 'Daily'
                )
            ),
            array(
                'attributes' => array(
                    'value' => 'weekly',
                    'data-item' => 'orange'
                ),
                'options' => array(
                    'label' => 'Weekly'
                )
            ),
            array(
                'attributes' => array(
                    'value' => 'monthly',
                    'data-item' => 'pear'
                ),
                'options' => array(
                    'label' => 'Monthly'
                )
            ),
        ),
    ),
));

My reason for wanting the above, is that I want to use JavaScript to change something upon selecting a radio button, so it needs to hold data attributes.

Is anything like this possible yet?

It can be done by providing an array (or an object which implements ArrayAccess) instead of a single value (almost as you wrote in your example).

$this->add(array(
    'type'  => 'radio',
    'name'  => 'duration',
    'options' => array(
        'value_options' => array(
            'daily' => array(
                'label' => 'Daily',
                'value' => 'daily',
                'attributes' => array(
                    'data-item' => 'apple',
                ),
            ),
            'weekly' => array(
                'label' => 'Weekly',
                'value' => 'weekly',
                'attributes' => array(
                    'data-item' => 'orange',
                ),
            ),
            'monthly' => array(
                'label' => 'Monthly',
                'value' => 'monthly',
                'attributes' => array(
                    'data-item' => 'pear',
                ),
            ),
        ),
    ),
));

This should work on radios, multi-checkboxes & selects too.
