CGI problem (Help!!)

Posted on 2002-05-28

In my CGI form (written in Perl), I have
TWO  "Submit" buttons and when pressed, they
call 2 different functions from within
the same CGI page.
The submit buttons have the values
of "Submit1" and "Submit2". When pressed,
"Submit1" repaints" the CGI page..
For example, At the main CGI page, users
are shown some "select" options.Now when
"Submit1" is pressed, it repents the screen
with new info selected by those "select"

But the form as well contains a file upload
button. And this value is required/used when
the "Submit2" button is pressed. Problem
is, if user selects a file with the file
upload button and then clicks "Submit1",
Submit1 function CANNOT repaint the page
with the "previously chosen" file by the
file upload button this is because the
input type "file" does NOT have a "value"
parameter (so use of a hidden field does not

Here is the code:
#! /usr/bin/perl
use CGI qw/:standard :html3/;
...header etc..
$action = param('go');
if ("$action" eq "Submit1")
elsif ("$action" eq "Submit2")

sub do_Submit1
...get some parameter from the main page generated by
...print_main_page() function..
print "<input type=file name=myfile>";
##No "Value" that I can specify above although I have
##it's file information....

sub do_Submit2
...calls some external script.

sub print_main_page()
print "", start_form;
print "<select name=myname>";
print "<option value=....></optrion></select>";
print "<input type=file name=myfile>";

print "<input type=submit name=go value=Submit1>";
print "<input type=submit name=go value=Submit2>";
print "<input type=file name=myfile>";



Please help.

It's possible to do what you want, but it's not easy. The reason you can't set the filename directly is because that would be a security risk. You'll need to do it with a signed javascript that you set to run automatically, using the onLoad property of the BODY tag. The script will look something like this:

 function setfile() {'UniversalFileRead');

Here's the signing tool you'll need:
