How to create a custom profile plugin

Question

I want to write my own custom profile plugin, but the problem is that the available tutorials (here and here) are a little outdated.

Right now I'm looking at the setFieldAttribute(), the last argument is $group, and the documentation says:

string $group The optional dot-separated form group path on which to find the field.

And a usage example is this:

$form->setFieldAttribute('address1', 'description', 'PLG_USER_PROFILE_EI_FILL_FIELD_DESC_SITE', 'profile');

Do I need to change the value to the name of my plugin or is it the same ('profile')?

Answer 1

The group refers to a named fieldset element inside a form definition. Find the field you are trying to edit into the form definition and get the name of its parent fieldset element and use that for the group.
