Fabien,
Thanks. I was able to figure this out by creating a new sfWidgetFormSchema
inside the form. One more question. Why can I not set the "value" of a
checkbox? This seemed to be the best option, but still didn't work:
new sfWidgetFormInputCheckbox(array(), array('value' => $value));
Any reason why I can't set the value?
Thanks,
-- Ian

Subject: [symfony-devs] Re: Dynamic checkbox arrays for sfForms in 1.1
You can manipulate the widget and validator schemas as if they were
arrays... except they are not. Instead of creating an array, you need to
create a sfWidgetSchema, which behaves like an array.
So, in your case, you have 2 options:
* Create a form for your collection of widgets and embed it: symfony
will do the ground work for you
* Do everything by hand
Here is an example for the first option:
<?php
class ThingForm extends sfForm
{
public function configure()
{
// ...
$this->embedForm('group', new checkboxesCollectionForm());
}
}
class checkboxesCollectionForm extends sfForm
{
public function configure()
{
foreach (array('foo', 'bar') as $value)
{
$this->widgetSchema[$value] = new sfWidgetFormInputCheckbox();
$this->validatorSchema[$value] = new sfValidatorPass();
}
}
}
I've attached a screenshot for this example.
And here is the exact same example but you do everything by yourself:
<?php
class ThingForm extends sfForm
{
public function configure()
{
// ...
$this->widgetSchema['group'] = new sfWidgetFormSchema();
$this->validatorSchema['group'] = new sfValidatorSchema();
foreach (array('foo', 'bar') as $value)
{
$this->widgetSchema['group'][$value] = new
sfWidgetFormInputCheckbox();
$this->validatorSchema['group'][$value] = new sfValidatorPass();
}
}
}
If you want to use the <?php echo $form ?> statement, you will have to
decorate the collection like this:
$this->widgetSchema['group'] = new
sfWidgetFormSchemaDecorator($this->widgetSchema['group'],
$this->widgetSchema['group']->getFormFormatter()->getDecoratorFormat());
