Render Radio Element in Zend Forms - php

Question

I have defined a form using Zend\Form. In that, there is a radio button.
$this->add(array(
'name' => 'nationality_radio',
'type' => 'Radio',
'options' => array(
'value_options' => array(
'local' => 'Local',
'expatriate' => 'Expatriate',
),
)
));
Its value is not directly binded with database column. But it should populate correct value taken form DB and save user input back. (eg - if value of table column nationality is local it should select local in radio button)
When rendered it should display as..
On form load, it will a select option considering column nationality. It will contain value either local or expatriate
<?php
if ($candidate->nationality == 'local'){
$local = 'checked';
} else if ($candidate->nationality == 'local'){
$expatriate = 'checked';
}
?>
In plain HTML i can do it as below,
<div class="profile_item list-group-item">
<span class="item_title">Local: </span>
<span class="item_content"><input type="radio" name="nationality" value="local" <?php echo $local ?>></span><br>
<span class="item_title">Expatriate: </span>
<span class="item_content"><input type="radio" name="nationality" value="expatriate" <?php echo $expatriate ?>></span>
</div>
But since Zend form rendered using <?php echo $this->formRow($form->get('nationality_radio')); ?> I couldn't do it. It just displayed as below.
How can i achieve my requirement ?

Answer 1

For set the value, within controller method:
$form = new YourFormClass();
//are you using fieldsets? let's say no...
//if accepted value for $candidate->nationality could be only 'local' and 'expatriate',
//check the scope with your defined value_options or use an if
$form->get('nationality_radio')->setValue($candidate->nationality);
On your view use formRadio helper:
<?php echo $this->formRadio($form->get('nationality_radio'),\Zend\Form\View\Helper\FormRadio::LABEL_PREPEND);?>
Check out documentation at: http://framework.zend.com/manual/2.2/en/modules/zend.form.elements.html#radio
or check classes:
\Zend\Form\View\Helper\FormRadio
and
\Zend\Form\View\Helper\FormMultiCheckbox
Accepted values for $labelPosition are:
const LABEL_APPEND = 'append';
const LABEL_PREPEND = 'prepend';

Try this
<?php
if ($candidate->nationality == 'local'){
$LocalChecked="checked";
}
else {
$expatriateChecked ="checked";
}
?>
<div class="profile_item list-group-item">
<span class="item_title">Local: </span>
<span class="item_content"><input type="radio" name="nationality" value="local" <?php echo $LocalChecked ?>></span><br>
<span class="item_title">Expatriate: </span>
<span class="item_content"><input type="radio" name="nationality" value="expatriate" <?php echo $expatriateChecked ?>></span>
</div>
