[phpesp-dev] [patch] new feature: invitations

[Jochen S. <js...@us...>]

Hi there,

this patch (against 1.6.1) should contain my last 2 submissions=20
(show-results-on-survey-completion and hidden-multicopy-functionality)=20
and a new, bigger feature that I call invitations.

With invitations, you can invite a group to a survey. The members of the=20
group will receive an e-mail with the URL to access the survey and their=20
credentials. An important feature is that phpESP then keeps track of=20
incoming responses, i.e. one can see on the status page of the=20
respective invitation when, and more importantly if users have completed=20
the survey.


A word of warning: Realms seems to be shallow in the 1.6.1 phpESP=20
architecture (has that changed to 1.7? I think there is a login-form=20
now?). It seems as if both user and realm are part of the primary key in=20
the users table, but due to http constraints, it can not be determined=20
which group a user belongs to when he/she loggs in, so de facto the user=20
name is the only primary key. One might run into trouble if there are=20
users in different groups that share the same user name.

If user "A" group "A" is invited to Survey "A" and another Username "A"=20
in group "B" is also invited to Survey "A", their participations would=20
be recorded as the identical user in both group A and B.

Maybe I'll pull a CVS version and rewrite those features for 1.8 -- I=20
think 1.7 should not be destabilized by new features as it is already a=20
release candidate.
