Symfony：如何更改操作中的表单字段属性？ [英] Symfony: How to change a form field attribute in an action?

问题描述

我有一个函数形式的sfWidgetFormChoice作为复选框的列表。我可以通过以下选项将复选框设置为已选中：

I've got a functioning form with a sfWidgetFormChoice that acts as a list of checkboxes. I'm able to set the checkboxes to "ticked" by default with the following:

'status' => new sfWidgetFormChoice(array('choices' => array(1, 2, 3), 'multiple' => true, 'expanded' => true), array('checked' => 'checked'))

...其中复选框称为状态，可能的值为1/2/3 。

... where the checkboxes are called "status" and the possible values are 1/2/3.

但是，由于其他原因，而不是默认情况下勾选它们，我想能够从一个操作中控制已检查状态。我如何做到这一点？

However, because of something else, instead of ticking them all by default I'd like to be able to control the "checked" status from an action. How do I do this? I've tried everything logical I can think of but I just can't figure out the right syntax.

基本上，我在寻找类似的东西：

Basically, I'm looking for something like:

$this->form->getWidget('status')->setAttribute('checked', 'checked');

任何人？
