1) Change the required fields in the registration form for a new user.

Let me know which field you want to change, so I'll assist you.

2) Add a new field for the registration form

If you want to ask for new fields during registration then you need to use User custom details, which is used to ask the additional details from the customer.

Let me know which field you want to change, so I'll assist you.

I want to delete the "state" field because we don't really have states in Austria and we don't use it for adresses in Austria, Germany or Switzerland. ZIP Code and City is enough.

Hey Kluas,

To remove state field from PayPlans Inbuilt registration, you can do it with the template overriding.
For this you need to do the changes here

1. Go to file : root\components\com_payplans\themes\wireframe\registration\auto\default.php, near line no. 67. find this code.

<div>

					<?php echo $this->html('floatLabel.text', 'COM_PP_CHECKOUT_STATE', 'state', $data['state']); ?>

				</div>

Remove this code.

Do the changes with template overriding so changes will not lost.
