After User registers, pick up username as session variable

[Scott B]

I have a page with a simple user registration on it. On Submit, I'd like the user to be redirected to another page (I got this part) WITH the username as a session variable. I have a feeling that defining the session variable using a5ws_getCurrentuser() would not work, since the user is technically not logged in. Any ideas on this one?

Thanks!

I'm applying my desktop experience here, so if it is out of line, I'm sorry.

Can't you just define a global variable when you open the APP , then assign the user sign-in name to the variable. If you define it as global, you should be able to see it anywhere. Just place the variable on the next page.

Scott,

I'm not sure it's exactly the same thing but when I have a user login, I redirect to an intermediate page where I can set the session variables, then redirect to where they are supposed to go after that. I can't see why it wouldn't work in your case. An interim page with code something like this:

<%a5
'dim variables
dim session.current_user_fname as c
dim session.current_user_lname as c
dim session.current_user_email as c

'get current user firstname & lastname
cn = "::name::Engineering"
table = "Employees"
filter = "username = '" + a5ws_getCurrentUser() + "'"
result_fname = "firstname"
result_lname = "lastname"
result_email = "email"

session.current_user_fname = sql_lookup(cn,table,filter,result_fname)
session.current_user_lname = sql_lookup(cn,table,filter,result_lname)
session.current_user_email = sql_lookup(cn,table,filter,result_email)

'send the logged-in user to the index page
response.redirect("home.a5w")

%>

Re: After User registers, pick up username as session variable

Thank you both, much appreciated. Stephen, I think its close, but my problem is that the user is not logged in yet. In order to get the a5ws_getCurrentUser() I need them to be logged in. By the way, can't you put your code directly on the login page, rather than have an intermediate page? I think Jerry Brightbill has an article on that.

This is not true, if you have security on the page and you can get to it, then you are logged in. The example I showed above is working code from my application on a page called Login_Processing.a5w. This gets the username from the login page and gets the users firstname & lastname from my SQL database and assigns them to session variables. Then I redirect to my home page called home.a5w where I display the logged in user firstname & lastname in the header. Obviously if you just want username only, you can get away with something much simpler. Something like this should work:

dim session.current_username as c

session.current_username = a5ws_getCurrentUser()

response.redirect("home.a5w")

I don't know, probably, I have never seen Jerry's article. I was taught to use an intermediate page. The main page of most apps can get quite messy with lots of code. It is much neater and easier to maintain, imho, to gather this information right after login using a single login processing page. Besides, the user doesn't see anything and doesn't know any different. They just think they're logging straight in to the app. It's entirely your choice, just trying to give you options.

Stephen, this is extremely helpful. Thank you very much.

Re: After User registers, pick up username as session variable

Here is another thought.

I have the code below in a small file called header.a5w. Then every A5W page of my app has this this xbasic code included: a5w_include("header.a5w") which is placed just after the <html>
<head> <%a5 This is loaded then and run on each page. This allows some things to happen on each page call.

Checks to see if a valid user is on the page, if not they are directed to the log in page. If the session timed out, the user is directed to the login page. If the user just logged in and doesn't have the required session variables set up yet, (in the example it checks for the variable "session.__protected__district") then it will run the xbasic code to get the required session variables. If the required variable is valid, then the routine just ends.

Since my app also displays the user name and and a 'logout' link this a good place to add that for display at the top of the page. Some users can change their district code, so if they do, then the display is changed as well. Since this routine checks for valid variables, it is does not affect performance for a valid logged in user.

Mike


''check to see if a user is logged in. If not then goto login page
userid = a5ws_getcurrentuser()

If userid = "" then
a5ws_logoutuser(session,request,response)
session.reset()
response.redirect("index.a5w")
end
end if

'if user session variable is not blank then end this process
if eval_valid("session.__protected__district") then
'display user name and district code with logout link, allows for change in district code if the user changed it.
? "Logged in: " + session.fullname + " " + session.__protected__district + "<a href=\"Logout.a5w\">(Logout)</a> "
goto quit
end if

'routine here to get user session variables for newly logged in user
dim cn as SQL::Connection
dim args as SQL::Arguments
...routine to get user info for session variables
...

Re: After User registers, pick up username as session variable

Session variables are always available you dont have to be logged into the system to use them every visit creates a session folder.
When the user submits the grid set the datasubmitted to some session variables and use them where ever you want. sort of like this

after insert

session.username = datasubmitted.name

then put ?session.username inside some a5code on your page.

Stephen, you may have been taking this from some older stuff so I am sure you already know this but there is no need to dim session variables now.

Thanks Chad, I didn't know that, or I did and forgot. Yeah, this is code dating back to v10.

Hi Chad
"then put ?session.username inside some a5code on your page."
Sorry for been slow...
Understood the first part of you commend.
Can you please explain the above, perhaps with an example?

Many thanks
Tasos

Re: After User registers, pick up username as session variable

<%a5
?session.username
%>

The above code would need to be included wherever you would want the username to show up.
