I'm struggling with the Dynamic Registration documentation.

For instance, there is a very short paragraph about core DNN fields and Dynamic Fields, but it doesn't say how many Dynamic Fields can be mapped to Core fields.

What do I do with the other dynamic fields once I've mapped a single core field to a dynamic field?

The documentation started off like a well written walkthrough/tutorial, but as you try to get past the repetition of screenshots, the doc content seems to wane quite a bit.

Am I just thick or what? Perhaps it's just me!

Mike,

Hi. Much of this has to do with the fact that core fields (and core extended fields) have changed throughout the history of DotNetNuke and therefore Dynamic Registration as well. The real purpose of the core field integration is to keep your Dynamic Registration in sync with DotNetNuke. This isn't necessary except in cases for example where you might use another module to import users and you want them to have their DNN data displayed within Dynamic Registration or if you used the core manage users area or somehow modified the core data without using Dynamic Registration. Because of this we allow the ability to 'link' core fields directly with dynamic fields. This means that every time the user saved their data its saved in both the Dynamic Registration tables and also the core tables. If a field is linked and you change the core fields it will pull those values in instead of Dynamic Registration etc...

Basically you can link/map as many dynamic fields with core fields as you would like. If you decide not to map a field there is no harm in doing this, only if you wanted to export user data or access that data within the core somewhere and then you might have problems. Modules such as our Dynamic User Directory module support both accessing the core data and the Dynamic Registration data directly so it wouldn't matter for modules like that example but it might matter if you were using another 3rd party tool to manage users with etc..

Hope this helps with understanding the purpose of mapping DNN fields with Dynamic Fields etc...
