Automatic Login

[WEC]

I am using Checkbox V4.6.4.7

This question pertains to automatically logging a user in upon invitation.

I have 3 surveys set up as with permissions - 'all registered users'. Survey 1 will eventually redirect the user to either survey 2 or survey 3, and I was wondering if there was a way to redirect them to that survey and having them automatically logged into that survey as well (such as the invitation option 'automatically log user in'.

I need the ability to track the respondent, so I can't make those surveys public. Obviously when I make them 'all registered users' or 'access list', the system will naturally prompt for a username/password, which I wont to avoid since they already logged in via the original survey!

Thanks

You can use the pipe feature to construct a url that automatically logs users in. You will want to add "&u=@@GUID" to the end of the redirect url. A user's GUID uniquely identifies them and can be used to authenticate users. For example:

http://localhost/Survey.aspx?u=@@GUID

I am not sure why, but the forum software keeps editing the example url. It should be in the format http://localhost/Survey.aspx?s=<Survey Guid>&u=@@GUID

Ah, the GUID is what I needed; I knew there was some Identifier I could pipe in their but was picking the wrong ones. Thanks!

The name of the query parameter matters too, it has to be u. The pipe is located under User Attributes -> GUID.
