自定义布局到sfWidgetFormDoctrineChoice禁用复选框

Question

Good morning,

In Symfony 1.4,
I tried to do what is explained here : Customizing layout to sfWidgetFormDoctrineChoice
But it doesn't work. Instead of adding a thumbnail, I just want to hide the <li> before the input, and in some condition disable/hide the checkbox input but show the label anyway .
When I add the renderer without argument, I get this error :
sfWidgetFormMySelectCheckbox requires the following options: 'choices'.

Here is my formatter code :

class sfWidgetFormMySelectCheckbox extends sfWidgetFormSelectCheckbox
{
  public function configure($options = array(), $arguments = array())
  {
    parent::configure($options, $arguments);
  }

  protected function formatChoices($name, $value, $choices, $attributes)
  {
    .....

      // new
      $inputs[$id] = array(
        'input' => sprintf('| test | %s',
          $this->renderTag('input', array_merge($baseAttributes, $attributes))
        ),
        'label' => $this->renderContentTag('label', self::escapeOnce($option), array('for' => $id)),
      );
    }

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

And now the form where I call it :

$this->setWidget('aaa', new sfWidgetFormDoctrineChoice(array(
    'model' => 'Aaa',
    'expanded' => true,
    'multiple' => true,
    'add_empty' => false,
    'query' => $query,
    'renderer' => new sfWidgetFormMySelectCheckbox()
  )));

Thanks for your help !

According to the docs you have to pass the choices option to the renderer object. Try something like this:

$this->setWidget('aaa', new sfWidgetFormDoctrineChoice(array(
    'model' => 'Aaa',
    'expanded' => true,
    'multiple' => true,
    'add_empty' => false,
    'query' => $query,
)));

$this->widgetSchema['aaa']->setOption('renderer', new sfWidgetFormMySelectCheckbox(array(
    'choices' => new sfCallable(array($this->widgetSchema['aaa'], 'getChoices'))
)));

So basically you want the renderer object get the choices from the parent widget. To do that you have to pass a sfCallable object which takes an array as the first argument in which you pass the instance of your parent widget and the name of the function getChoices .

Remember also that the expanded option is not used when you override the renderer .
