Passing 2 parameters/arguments to a script?
|
Can't Post
|
|
I want to call a script from a form within another script (actually the script is calling itself again, but you get the idea). Here is the start of the form:
print $query->startform(action=>"$script_name/results?filename=$Answerfile", -TARGET=>"results");
One of the things that gets passed is the results of the form. The other is information after the ? in the path
above(?filename=$Answerfile). It gets taken care of by the following code at the beginning of the script:
my $Answerfile = param('filename'); #This is how the Answerfile path is passed
Do you know how I can pass both of these things (the path and the results) to this script? They seem to conflict with each other. FYI, the reason this script calls itself is because it implements frames (it
is a online quiz). One subroutine does the frame HTML, another makes the question/form window, and the last one makes results frame. Also, as you may have guessed by now, I'm using CGI.pm.
For those of you who want to see my entire script, here it is (keep in
mind, I'm new at this):
Thanks in advance for any help you guys can provide.
