Hi guys!
I guess most of you have experienced the problem of duplicated
submissions due reload button I have seen some protections against it
on the web, and I would like to implement it on my apps.
My first thought is to compare the values being submitted with those in
the database, if they

counter-culture preference regarding Reply-to and lists)
Use CGI::Session, this deals with session management and random IDs
But how would you use this to ensure a form hadn't been submitted twice,
in the case where a client could
Sounds cool, do you use cookies for that?
Nope, I have an irrational dislike of cookies. I just drop it in as a
hidden field to the form. Of course, this requires that your form be
generated dynamically as opposed to being flat HTML.
Of course, this still has a 1 in a (my pseudorandom
I am using PostgreSQL too, it's great DBMS!
Thanks for your comments guys!
best regards,

I'm clearly not understanding something here. I'm trying to use $self-param() the
same way it's used in the docs. The print statement in setup prints mydbh instead
of the DBI reference. If I uncomment the $dog lines, it prints the DBI reference
fine.

Don't use this, CGI::App handles CGI for you. (you can get the CGI object
via $self-query())
I suspect param() is getting mangled somewhere along the line. Remove the
use CGI line and try again.

That did it. I figured it was something simple.
Thanks!

In the case where the form is being used to insert some data into a

In the form display run mode, select the next available unique ID for

Postgres handles this gracefully with it's SEQUENCES feature. After
user1 calls up the form, user2 will be returned ID 12 rather than 11. So
there's no possible conflict like that.
Okay. I'm just starting to play with with Postgres, so here are a few
