Thanks for your reply Jamie, is there any current documentation/guides where I could take a look at how to do this with javascript/jquery, or could you provide any pointers for me?
I have been editing the php manually to try and achieve this but I'm not great with jquery and php I'm afraid, if it was .net/asp I'd probably be ok. I did find the moodle api info so I've been able to add and validate custom field entries by adding those into the singup php page but I haven't had much luck past that.
Any help would be greatly appreciated.
Thanks,
Andy
