[phpesp-dev] proposal: survey availability constrained by date

[Bishop B. <ph...@id...>]

All,

I have a client need to constrain a survey's availability to a given =20
window of time.  In other words, survey 1 is available between dates X =20
and Y only: not before X and not after Y.

I propose to add an optional opening_date and closing_date column to =20
survey, as well as input elements on the General tab of the survey =20
create/edit page.  The survey logic would alter, as follows:

A survey is available if and only if:
  a) the existing access control logic is satisfied, and
  b) one of the following conditions:
     If opening and closing are set && opening <=3D now <=3D closing
     If opening set and closing is not set && opening <=3D now
     If opening not set and closing is set && now <=3D closing
     If opening not set and closing not set

I would also add a data element to the tables on the dashboard, so a =20
respondent can see the temporal availability.  I'd also need to update =20
the error messages appropriately.  And the help documentation.

With this addition, no existing data will be affected.  Those who wish =20
to constrain to a given date range may.

Thoughts?
