Hi Russ, I have a problem here not like you but has to do with forms and unset.

Situation: I have 3 embed forms, I’m going to use just one, the other two will be unset through a select option. But if this form has required fields no filled in the validation page I will lose the unset embed forms but I still have my select options which won’t work properly because the unset embed forms.

Do you have some idea ?

This kind of method has already been proposed to symfony in http://trac.symfony-project.org/ticket/5525. Slightly different implementation, but very much the same thing…

Nice idea, maybe it’s something that can be added to the core?

It would be better off in sfForm I guess… Have you submitted a patch?

I’ve had the same issue as you (wanting to keep only a few fields but not wanting to have many ugly unset:s in the code) so I stuck this method into BaseFormDoctrine:

/**
* unsetAllFieldsExcept
*
* Unsets all fields except for the ones defined in func_get_args
*
* @return void
**/
public function unsetAllFieldsExcept()
{
$keepFields = func_get_args();
foreach($this as $key => $value) $baseFields[] = $key;
$temp = array_diff($baseFields, $keepFields);
foreach ($temp as $unsetField) unset($this[$unsetField]);
}

Using the above method in this case would allow one to use only the ‘amount’ and ‘reduced_amount’ of the form by doing:

public function configure()
{
$this->unsetAllFieldsExcept(‘amount’, ‘reduced_amount’);
}
