[FX.php List] Weird session variable issue

[Bob Patin]

Leo,

Thanks for the reply; 

> What you should do is debug the application source code so that you isolate the matter. Log the state of the session and its data at strategic points during the requests, so that you can tell exactly WHEN the data goes missing.

Well, I did that; I added a 2nd function to write to a test database after each step of the process. What is interesting is that when this error occurs, even after just the first form (there are about 4 steps to the application process), we sometimes get blank fields on the test database—which indicates to me that FileMaker is creating the record properly, but there isn’t any data in the session variables.

It’s a fairly simple process: I retrieve the form values, save them all to session variables, and then in my test function I retrieve these and write them to a test record. i do this in 4 spots in the process, to see if the data is being retained, and to see where it breaks down. It’s almost as though the session variables just aren’t being written at all...

not really that much, but a lot of values; these are names, address, that sort of thing; none of the session variables contain more than about 30-50 characters, I would guess.

That’s what I thought too, but thought I’d ask… 

The other strange thing is that I’m using JQuery validate() to make sure users can’t leave a form without filling it out completely, which ensures that I’m capturing all the values I need to capture. However, I’m beginning to wonder if the GET that I’m using in JQuery isn’t actually retrieving all the values.

Thanks,
