您需要创建一个自定义小部件类。我扩展了收音机小部件并更改了格式化程序功能。
您可能需要自己稍微定制一下。但是下面的myWidgetFormSelectRadio
类会将每个单选字段包装在您指定的标签中。
// \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);
}
}
然后在你的表单类中
// \lib\form\myForm.class.php
public function configure()
{
$this->widgetSchema['my_field'] = new myWidgetFormSelectRadio(array('choices' => $choices));
// ....
}
您是否偶然使用 Twitter Bootstrap?如果是这样,那么您也需要扩展 Symfony 复选框小部件。如果你这样做,那么你可能想要扩展 sfWidgetFormChoice 类并更改getRenderer()
方法,以便它在呈现单选/复选框字段时使用你的myWidgetFormSelectRadio
和类。myWidgetFormSelectCheckbox
// \lib\widget\myWidgetFormChoice.php
class myWidgetFormChoice extends sfWidgetFormChoice
{
public function getRenderer()
{
if ($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());
}
}
然后在你的表单类
public function configure()
{
$this->widgetSchema['my_field'] = new myWidgetFormChoice(array(
'choices' => $choices,
'expanded' => true,
'use_my_custom_widget' => true,
));
// ....
}
