Hi All,

I wrote a web wizard with cgi which contains of a couple of 4 steps.
In each step the user can go forward and backward. My problem was that
the script has to remember what the user chose in each step. I thought
about an option to send the selections from the other steps with
hidden fields. This is a little tedious, so I decided to write the
wizard with javascript. This solution has two problems. 1) All the
steps have to be loaded from the beginning. 2) Accessibility issues.

Is there a convenient solution for this in perl ?

Thanks in advance,
David

Look at CGI::Session (http://search.cpan.org/perldoc?CGI::Session)
there is even a tutorial.

I don't find it very tedious. Maybe I have low standards, or maybe you are
doing it wrong. Can you show us some relevant code?

Now is my code not interesting because i make all the work in
javascript and get a cgi, as i would not have a wizard. All the
parameters are sent once. My problem was that i have to remember what
i chose in each step. lets say if i have a wizard with 4 steps. I
have in step 2 of the wizard a multiple select and i select there 5
items. Then i go to step 3 and then back to step 2. the program has to
remember the selection of step 2. I can make this with hidden fields
where each control of every step is a hidden field. But in every step
of the wizard i have to give in the html for every control of the
other steps a hidden field
This makes it tedious

Not perl but, use a hidden ilayer or div for each step. Enclose all
the layers in the same form element, only show the layer they are on.
That way all the form elements retain their values from one step to
the other and you only have a single post back to the server when they
are done.

use CGI;
my $cgi=CGI->new;
#.....
print $cgi->hidden('param_name');

Thanks, I think this will do the trick. Something like this.
foreach my $param_name ($cgi->param) {
print $cgi->hidden($param_name,$cgi->param($param_name));
}

I think the below should work:

foreach my $param_name ($cgi->param) {
print $cgi->hidden($param_name);
}

CGI.pm supports "sticky fields", which means if you used CGI both to
parse the submitted form and print a new form, it automatically uses
the values of just-parsed elements to populate the newly printed ones with
the same name.
