Symfony 1.4形式模板

Question

我正在安装Symfony 1.4,我们需要重新设计以匹配新的公司品牌.新皮肤的要求之一是单选按钮具有以下语法 -

<label><input name="foo" type="radio" value="bar" id="foo_bar"><span></span></label>

但是单选按钮的默认Symfony代码是 -

<input name="foo" type="radio" value="bar" id="foo_bar">

我可以更改模板在哪里添加附加元素以包围输入标记？我通过代码搜索了高低,我似乎无法找到生成此代码的位置.

提前致谢!

您需要创建自定义窗口小部件类.我扩展了无线电小部件并更改了格式化程序功能.

您可能需要自己定制一点.但是下面的myWidgetFormSelectRadio类会将每个无线电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));

    // ....
}

您是偶然使用Twitter Bootstrap吗？如果是这样,那么您还需要扩展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,以便它在渲染radio/checkbox字段时使用你的myWidgetFormSelectRadio和myWidgetFormSelectCheckbox类.

// \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());
  }
}

然后在你的表单类中

public function configure()
{
    $this->widgetSchema['my_field'] = new myWidgetFormChoice(array(
         'choices' => $choices,
         'expanded' => true,
         'use_my_custom_widget' => true,
    ));

    // ....
}
