render individual option from radio Element in Zend Forms - php

Question

I have this element inside my Zend form
$genderOptions = array( 'male'=>'male', 'Female'=>'Female');
$gender= new Zend_Form_Element_Radio('gender');
$gender->setDecorators(array('ViewHelper'))
->setAttrib('name', 'gender')
->setAttrib('class', 'required error pull-right')
->setAttrib('id', 'gender')
->setRequired(false)
->setMultiOptions($genderOptions);
And I want to retrieve the inputs individually in the viewscript (phtml file). I've tried
as
<div>
<span>Male</span>
echo $this->myForm->gender['male'];
</div>
<div>
<span>Female</span>
echo $this->myForm->gender['female'];
</div>
how can I do that using Zend Form?
Thanks

For form elements extending Zend_Form_Element_Multi you can use the getMultiOption($option) to fetch a single option.
View.phtml
<div>
<span>Male</span>
<?php echo $this->myForm->gender->getMultiOption('male'); ?>
</div>
<div>
<span>Female</span>
<?php echo $this->myForm->gender->getMultiOption('female'); ?>
</div>
Alternatively, you may want to check that the option is available before you attempt to use it (or you will get NULL)
<?php
$gender = $this->myForm->gender;
$option = $gender->getMultiOptions(); // returns assoc array
if (isset($option['male']))
printf('<div><span>Male</span>%s</div>', $option['male']);
if (isset($option['female']))
printf('<div><span>Female</span>%s</div>', $option['female']);
?>
Edit
Having re-read your question I can see you're looking for the individual radio elements, rather than the value.
This may be harder to achieve as the Zend_Form_Element_Radio class actually represents all the radio options; Where the view helper Zend_View_Helper_FormRadio loops over each 'option' (i.e. male, female) and returns the complete HTML string with each <input type="radio"/> already included.
Shockingly the Zend_View_Helper_FormRadio helper actually has all of its HTML generation code within one method; This makes it very hard to override it without duplication.
Personally, I would :
Create a new helper MyNamespace_View_Helper_CustomFormRadio extending Zend_View_Helper_FormElement
Copy the entire contents of the Zend_View_Helper_FormRadio (FormRadio()) into your new helper
Modify section where the each radio input is created.
For example
$radio = '<div><span'
. $this->_htmlAttribs($label_attribs) . '>'
. (('prepend' == $labelPlacement) ? $opt_label : '')
. '<input type="' . $this->_inputType . '"'
. ' name="' . $name . '"'
. ' id="' . $optId . '"'
. ' value="' . $this->view->escape($opt_value) . '"'
. $checked
. $disabled
. $this->_htmlAttribs($attribs)
. $this->getClosingBracket()
. (('append' == $labelPlacement) ? $opt_label : '')
. '</span></div>';
Then you can use it within your view with $this->customFormRadio()
