Hi to everyone,
i want to add a tab on the Security section, near Members and Pemissions tabs. I want insert inside that tab a form to edit an User-Defined DataObject. How to do that?
Thanks to everyone.

you'll have to subclass SecurityAdmin: http://doc.silverstripe.com/doku.php?id=leftandmain (customizing through addStaticVars()) and overload the getEditForm() method.

Hi Ingo,
thanks for you reply. I tried to do that you advice me, but it seemd don't work.

This is my code:

class CIFProfileForm extends SecurityAdmin
{
public function getEditForm($id)
{
$form = parent::getEditForm($id);

$field = $form->Fields();

$field->push(new Tab("Profili",new TextFiled("ciccio")));

$field->setForm($form);
return $form;
}
}

and i add the follow line on the _config
Object::useCustomClass("SecurityAdmin","CIFProfileForm");

Do you have any ideas to fix it?
Thank you very much.

can someone help me?
Thank you

$myForm->Fields() will give you an object copy rather than reference, meaning that you don't actually alter the original formfields when pushing new stuff into it.

$fields = $myForm->Fields();
$fields->push(...);
$myForm->setFields($fields);
