Selective pages and data based on login

[Steve Wood]

Keith,

I put the answer to your question posed in a private email here, for forum user's benefit.

You question:
<<
I am tring to help a school set up their WAS login. What they want to do is have the nornal Login ie User name and Password, but depending whether they are Admin, Teacher or Pupil will determin which page opens next for them. Only the Classes for the logged in Teacher can be seen by that Teacher and likewise only data for that Pupil can be seen by the logged Pupil.
>>

In the users table have a field for User_Type (or similar). Choices there are Pupil, Admin, Teacher. In the LoginDialog's AfterValidate event, set a protected variable to whatever is in that User_Type field. Also set the Security Level for each, from lowest to hightest, 1=Pupil, 2=Teacher, 3=Admin.

To accomplish what I think you want, you don't really have to "send them to a different page" depending on their status. Have everyone go to the same page with a Main Menu using Alpha Navigation component. Use the Security Levels to determine who sees what menu option.

Now, assuming one of those options available to all was See Your Class Listing (or similar) you will need a Case statement inside the A5W page with the grid that shows your class listing. This statement will selectively filter the data depending on their User_Type. That would look similar to this:

 
if eval_valid ("session.User_Type") then 
select
 case session.User_Type = �ADMIN�
 tmpl_Jobtracking.DBF.filter = your filter here
 case session.User_Type = �PUPIL�
 tmpl_Jobtracking.DBF.filter = your filter here
 case session.User_Type = �TEACHER�
 tmpl_Jobtracking.DBF.filter = your filter here
 case else
 tmpl_Jobtracking.DBF.filter = your default filter here, if applicable
end select
end if

And if I want to dynamically change the filter between Pupil, Teacher, and Admin. How would I do that?

Re: Selective pages and data based on login

If by dynamically you mean, "after I've logged in, I want to switch myself between Admin, Pupil and Teacher" - then:

Just create a dialog with the single choice of those three and have the AfterValidate event update the session.User_Type variable to the new value.

Steve,

Thanks for reply, you suggest that "you don't really have to "send them to a different page" ", but that is just what I do want to do.

I understand how data fields can be selected according to security levels, this I will do on the selected pages according to 'Type' of User.

Re: Selective pages and data based on login

Its the same as the code in my first post, except you put in the propert response.redirect("mypage.a5w") for each choice. This would go in the logindialog's aftervalidate event. Note, this will not prohibit others from going to pages not designated for them, if they guess the page. To restrict that you have to check to make sure they have the appropriate Type. Use something similar to how logintest.a5w works.
