如何更改 symfony 中 sfWidgetFormSelectRadio 的行为？

发布于 2024-08-23 11:55:01 字数 353 浏览 10 评论 0原文

new sfWidgetFormSelectRadio(
                array('choices' => $images)));

上面将渲染每个选项，如下所示：

<input type="radio" name="name" value="image_path">

如何使用最少的代码使其以这种方式渲染：

<input type="radio" name="name" value="image_path"><img src="image_path" />

原文

new sfWidgetFormSelectRadio(
                array('choices' => $images)));

The above will render each option something like:

<input type="radio" name="name" value="image_path">

How to make it render this way with minimal code:

<input type="radio" name="name" value="image_path"><img src="image_path" />

这是未经测试的，是我直接阅读 Symfony API 文档

像这样重写 formatChoices() 方法：

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';
      }

      $inputs[$id] = array(
        'input' =>
          $this->renderTag('input', array_merge($baseAttributes, $attributes))
          . $this->renderTag('img', array('src' => self::escapeOnce($key))),
        'label' => $this->renderContentTag('label', self::escapeOnce($option), array('for' => $id)),
      );
    }

    return call_user_func($this->getOption('formatter'), $this, $inputs);
  }
}

这样您基本上就将 img 标记附加到输入中。

在表单的 configure() 方法中，您需要从使用 sfWidgetFormSelectRadio 切换到使用 myWidgetFormSelectRadio 才能使用新的小部件。

让我知道这是否有效;-)

This is untested and straight from me reading the Symfony API docs for that widget. You'll need to extend the sfWidgetFormSelectRadio class, call it something like myWidgetFormSelectRadio and stick it in lib/widget/myWidgetFormSelectRadio.class.php in your project.

Override the formatChoices() method like so:

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';
      }

      $inputs[$id] = array(
        'input' =>
          $this->renderTag('input', array_merge($baseAttributes, $attributes))
          . $this->renderTag('img', array('src' => self::escapeOnce($key))),
        'label' => $this->renderContentTag('label', self::escapeOnce($option), array('for' => $id)),
      );
    }

    return call_user_func($this->getOption('formatter'), $this, $inputs);
  }
}

so you're basically appending the img tag to the input.

In your form's configure() method you'll then need to switch from using sfWidgetFormSelectRadio to using myWidgetFormSelectRadio to use the new widget.

Let me know if this works ;-)
