    I'm using Dynamic Forms to create a login screen that points to an external SQL user table - nothing to do with DNN users.  I've got a User Name and Password textbox along with a submit button and a hidden UserID field.  I've got the Validation SQL query working nicely to check the entry.  My question is, how do I get the UserID of the logged in user (coming back from some SQL query) into the UserID hidden field before the page is redirected.  Is there any other way to pass this UserID on?  Where do I perform this UserID SQL query?

    HI, userID of the person currently logged in can be accessed automatically with the token $(UserID). If you have a hidden field (shortname called: HiddenUserID) for example, just put a client side javascript on that hidden field and on page load like this:

    $(HiddenUserID) = $(UserID)

    Make sure to pass this HiddenUserID querystring along and on the page redirect, you should see HiddenUserID = UserIDNumber passed along on the URL.
    Try this out and see if it works for you. -- David

    I guess my main problem is knowing where to put the SQL query that returns the UserID.  The Validation Query only returns the value for validation so it doesn't look like I can return a UserID there.  It doesn't look like I can write a SELECT query in the Completion Events section to return the UserID.  Where does my SQL query go that can be fired after the submit button is clicked?

    HI John, try the following:
    1) create a hidden field or textbox field (read only) called GetUserID or something
    2) under "Advanced Field Options", for "Default Value", choose "SQL Driven" and then type in the following SQL statement:
    select userid as defaultvalue from users where userid = $(UserID)

    This will return the userid of the current login user. You can then "pass values of this question to querystring variable" to use on the next page redirect completion event. -- David

    Since I'm not using any of the DNN user information (pulling all of it out of a different database), $(UserID) won't have a value I'm looking for.

    If a use a default value SQL query for the hidden field, my SQL statement needs to look something like: but where do I get @Lastname from if it hasn't been filled in yet. I need this query to fire after the submit button is activated on this form.

    SELECT ClientID FROM [server].[database].dbo.Users
    WHERE MTLastName = @LastName AND MTFirstName = @FirstName AND Password = @Password

    Hi... Then next version (3.0 released in May/June) has a SQL Default for a question event type so you could get it right away, you might consider this route later and you can test this now on www.betasprings.com. Beyond that, where do you 'need' that? In an email event, or in a database somewhere etc? I believe you would have to use a SQL Event to 1. get the data and 2. store it wherever you need it (where is that?). You have access to a variable called $(UniqueCompletionID) that you could reference and update the table in the DynamicForms_QuestionResponse table directly maybe? Not sure where you need that data though... Once you have it what are you needing it to do?
