Shell Programming and Scripting

use this.

Code:

checkbox_group(
       -name=>'studenten_in_groep',
       -values=>[@member_keys],
       -defaults=>[@member_keys],
       -labels=>\%temp_members,
       -columns=>2),

i got it working just by looking at the examples in the docs for cgi.pm

1) your not useing referances correctly
2) dont misspell in your code.

A reference to an array is allways done using \@array, not [@array], isn't it?
Where am i misspelling?

I copied and pasted your code, but still the same.

is this homework? or a classroom exersize?

your missspelling: studenten_in_groep
it should be "student_in_group" it makes it much clearer when reading your code.

then you would have to send me your entire cgi program.

send it as a zip file.

the [] are for the parameters. they are used to group the values needed.

a referance to an array:
@bob=("eenie", "minie");
$joe=\@bob;

for (@$joe) { print "ArraryRef Items: $_ \n" };
ArraryRef Items: eenie
ArraryRef Items: minie

In a previous answer you give me a piece of code to use;
checkbox_group(
-name=>'studenten_in_groep',
-values=>[@member_keys],
-defaults=>[@member_keys],
-labels=>\%temp_members,
-columns=>2),
You tell me i use references wrong, but in this code for an array reference you use [@member_keys]. That confused me, because it is not a reference!
I wasn't asking you how a reference to an array works, i was questioning your use of @member_keys in your code..

from cpan about checkbox_group:
Here they give an example of using the array ref the way i use it..


What makes you think this is homework??

studenten is dutch for students and groep is dutch for group, so it is not misspelling, it is just a different language than english!!

I finally found a way to solve this problem...

I give the checkbox_group a value before it is printed, so now i use:

param('studenten_in_groep' => @member_keys);

checkbox_group(-name=>'studenten_in_groep', -values=>\@member_keys, -labels=>\%temp_members, -columns=>2),
