Hello Community,

currently I am trying to program a specialised bookmark website for users of our DNN website. I would like to ask the community the following question: is there any possibility to determine the user's data (user's ID, first name, last name, etc....) of the currently logged in user from the database ? So to speak, is there a way to find out the currently logged in user's data by using an SQL query against the database ? If yes, which tables are involved in the query against the database?  Thank you in advance.

Probaqbly not with a simple SQL query. There are methods that can be called from code, as in a module.

Thanks for the hint, how can I access these methods ? Do you have some sort of sample code ?

Have a look at the DNN API Documentation at https://dnndocs.com/api/

You probably should look at the namespaces whose names begin with DotNetNuke.Entities.Users.

As for coding, do you have any experience with DNN Module Development? What is your level of understanding of the internals of DNN? You'll probably want to get some sort of handle on that before starting off.

As for coding, you might get a head start with some scripts using the Razor module or install 2sxc for a much more powerful tool that also supports Razor. That will save you a bit in learning about module development, but to be replaced by learning how to use these tools. Check the Community Blog and also 2sxc.com for more information.

And, ask questions ...

For module development, Mitchel Sellers' book "Professional DotNetNuke Module Programming" is still available and relevant. Also, Professional DNN7: Open Source .NET CMS Platform.

Both of these books, though not current, will give you a lot of the basics.

Also, here is a nice series of blog posts on module development: https://www.dnnsoftware.c...s--blog-series-intro

As for code samples, you might want to get source code for various module from the DNN project itself for from https://github.com/DNNCommunity.

If i was starting out, I'd start with a simple 2sxc template that returns a list of users. You can then get a single user by userid, or by searching by some field. From there, you can get all of the data about a particular user. You can bypass much of this by getting the details of the current logged-in user.

To start with a simple module, Chris Hammond's templates are popular. Installed on a local machine, you can create a simple module, and work your way through by debugging it and looking at data returned by various calls.

And keep asking questions ...
