UX Login Session Variables

[hallidayo]

Hi,

I've created a UX login component which is working correctly, I know session variables can be used to filter the data, but how?

I only want to use the UserID to bind with the other components in my app, but where and how do I do this?

Thanks

Re: UX Login Session Variables

Have you tried setting the session variable with an ajax callback when the user pushes the login button?

Hi,

Thanks for the reply, Have you got an example of the code I can use for the callback?

Re: UX Login Session Variables

An ajax callback isn't required. There's a server-side event, onLogin, where you can check if the login was successful and setup any session variables you need that way:

if (e.loginSucceeded <> .f.) then
    dim pUser as p
    a5ws_logged_in_user_values(pUser)
    session.userId = pUser.userId
end if

Does this answer what was being asked? Or was the question more along the lines of how to populate/filter data in the UX with the logged-in user values?

Yeah you know, it would be sweet to have some pre-built session variables in Alpha. We all eventually want to reference these values in web apps. It should just be a drop down selection in the default values properties at this point...literally that code would work in all of our applications, and of course the next logical step from that is to filter records by the variable - another drop down selection in the query.
I can imagine there are many more useful variables that could be hard coded right into Alphas UX and Grids, on demand.

I see this as a separate area of web security, called Session variables, where you just select the ones you want per grid or UX just like permissions.
Then when you want to reference one as a default value, its already there as a dropdown selection in the Default values, etc.

In most web security configurations, there are very few values that are available from the security system itself after a user has logged in. Typically, the only value is the UserId / UserName which can be obtained anywhere with

a5ws_GetCurrentUser()

. About the only other values that could be usable would be the security groups, and that could be obtained with

a5ws_Get_User_Assignments(a5ws_GetCurrentUser())

Charles,

Just to mention, I have had something similar to that in my Framework for many years (see image). It ensures specific session vars exist mainly after login. However, at least in my applications, I never have more than a few session variables, five or six at the most. I use them to store a couple key values, and never for secondary values like "home address", etc.

That would be a great feature. I am currently trying to figure out how to bring a selected record's value over to another page and I am stumped. In the past I would find the action JavaScript equivalent of something, create it, then turn it into text and usually I would understand it from then on.
I will get it eventually, but it would fit the rest of Alpha's functionality to do this automatically.

Open a new page? Pass it as a parameter to the page.

That sounds like it is simple enough to be what I am missing, but I am not sure what you mean exactly. I dont want to pull this topic off track, however, as my problem really is not related to login sessions, so I started a new thread.

Page-To-Page Variables

Your input would be very much appreciated because I have already learned a lot from you so far, especially when you reply with answers and show how you found them. That alone is invaluable.
