You'll need to create a custom widget class. I've extended the radio widget and changed the formatter functionality.
You might need to customise this yourself a little. But the below myWidgetFormSelectRadio
class will wrap each radio field in a label like you've specified.
// \lib\widget\myWidgetFormSelectRadio.class.php
class myWidgetFormSelectRadio extends sfWidgetFormSelectRadio
{
protected function formatChoices($name, $value, $choices, $attributes)
{
$inputs = array();
foreach ($choices as $key => $option)
{
$baseAttributes = array(
'name' => substr($name, 0, -2),
'type' => 'radio',
'value' => self::escapeOnce($key),
'id' => $id = $this->generateId($name, self::escapeOnce($key)),
);
if (strval($key) == strval($value === false ? 0 : $value))
{
$baseAttributes['checked'] = 'checked';
}
$inputs[] = array(
'input' => $this->renderContentTag('label', $this->renderTag('input', array_merge($baseAttributes, $attributes)), array('for' => $id)),
);
}
return call_user_func($this->getOption('formatter'), $this, $inputs);
}
public function formatter($widget, $inputs)
{
$rows = array();
foreach ($inputs as $input)
{
$rows[] = $input['input'].$this->getOption('label_separator');
}
return implode($this->getOption('separator'), $rows);
}
}
Then in your form classes
// \lib\form\myForm.class.php
public function configure()
{
$this->widgetSchema['my_field'] = new myWidgetFormSelectRadio(array('choices' => $choices));
// ....
}
Are you using Twitter Bootstrap by chance? If so, then you'll want to extend the Symfony checkbox widget as well. If you do this then you might want to extend the sfWidgetFormChoice class and change the getRenderer()
method so that it uses your myWidgetFormSelectRadio
and myWidgetFormSelectCheckbox
class when rendering radio/checkbox fields.
// \lib\widget\myWidgetFormChoice.php
class myWidgetFormChoice extends sfWidgetFormChoice
{
public function getRenderer()
{
if ($this->getOption('renderer'))
{
return $this->getOption('renderer');
}
$prefix = $this->getOption('use_my_custom_widget') ? 'my' : 'sf';
if (!$class = $this->getOption('renderer_class'))
{
$type = !$this->getOption('expanded') ? '' : ($this->getOption('multiple') ? 'checkbox' : 'radio');
$class = sprintf($prefix . 'WidgetFormSelect%s', ucfirst($type));
}
return new $class(array_merge(array('choices' => new sfCallable(array($this, 'getChoices'))), $this->options['renderer_options']), $this->getAttributes());
}
}
Then in your form class
public function configure()
{
$this->widgetSchema['my_field'] = new myWidgetFormChoice(array(
'choices' => $choices,
'expanded' => true,
'use_my_custom_widget' => true,
));
// ....
}
