枚举选择列表。更改<option>标记值</option>

Question

默认情况下，Symfony 1.4会生成MySQL枚举的列表元素，如：

<option value="free">free</option>  
<option value="machine">machine</option>

如何更改选项标记值？，例如：

<option value="free">Different value than free</option>

Answer 1

您可以使用以下代码：

$choices = $this->getWidget('mywidget')->getChoices();
// supposing we know what needs to change...
$choices[1] = "new value";
// supposing we don't need other options/attributes
$this->setWidget('mywidget', new sfWidgetFormChoice(array('choices' => $choices)));
