Hi all, I was not sure where to post this so I'll address both the users and developers community because I expect both can use this. As I posted before, I needed some way to initialize some of the Customer User fields according to some rules I use at my site. I therefore added an extra column to the Customer User back-end Map table that allows one to enter a Perl expression or call to a method that will enforce these rules. In addition, you can also use this to verify and/or format the contents of the field that are typed in by the user. I admit, this is something that probably needs to be handled somewhere in the front-end (CustomerCreateAccount.dtl ?) but for now this works. As I am not sure whether I need to post a diff of the standard OTRS code I modified I thought I better post the complete module (I only changed one anyway). In addition there are some other files I will describe below: Kernel::System::DB The modified OTRS module Kernel::Config This is an excerpt of the User configuration file, only use for reference! Kernel::System::CustomerUser::Local::Init Local module containing initialization and formatting routines. ReadMe.txt Describes the whole thing. If you have any question, please do not hesitate to ask. Have fun, Tom Hesp
