Zend - 如何在viewscript中获取单独的单选按钮

Question

I'm setting the radio button like this:

$gender = new Zend_Form_Element_Radio('gender');
$gender->setLabel('Gender')
    ->addMultiOptions(array('m'=>'Male','f'=>'Female'))
    ->setDecorators(array('ViewHelper'))
    ->setRequired(true)
    ->addValidator('NotEmpty', true, $required);

And I want to retrieve the inputs it creates individually in the viewscript. I've tried:

$fields = $this->element->getElements();
$fields['gender']->getMultiOption('m')

But that just gets the value 'Male'. How can I get the individual radio inputs that addMultiOptions generates?

Thanks

Try using getMultiOptions()-method:

$fields = $this->element->getElements();
$options = $fields['gender']->getMultiOptions();

Here's an example how to get the radio buttons rendered:

$fields = $this->element->getElements();
echo "<label>{$fields['gender']->getLabel()}</label>";
foreach($fields['gender']->getMultiOptions() as $value => $label) {
    echo '<input type="radio" value="' . $value . '" name="gender" /> ' . $label;
}
