Getting value from URL

[JimJx]

Hi all,

I am working with a script that needs to pull info from a URL similar to:

http://www.myserver.com/cgi-bin/mycgi.pl?value1=12345&value2=abcde

I have seen a couple threads that were similar to this, but unfortunately they only confused me further.

I know the first thing I need to do is get the name/value pairs, but I have no idea how to do this with perl.

If anyone has a script handy, or if you know where I can find a good example online for something like this, it would be greatly appreciated.

Jim

#!/usr/bin/perl

$temp=$ENV{'QUERY_STRING'};
@pairs=split(/&/,$temp);
foreach $item(@pairs) {
        ($key,$content)=split (/=/,$item,2);
        $content=~tr/+/ /;
        $content=~ s/%(..)/pack("c",hex($1))/ge;
        $fields{$key}=$content;
}

$value1 = $fields{'value1'};
$value2 = $fields{'value2'};
...

$value1 will contain 12345
$value2 will contain abcde

Hope this helps!

#!/usr/bin/perl

use CGI;

my $cgi = new CGI;
my $par_day = $cgi->param('p_day');
my $par_rep = $cgi->param('p_type');

If you have installed the CGI module, it will be more simple to use the param function.

but don't forget that 'QUERY_STRING' means that your form must be method=get

Yes, I agreed with Hongkongian. By the way CGI.pm is a standard module that come with the distribution of Perl ver. 5 and above if I'm not mistaken. So I don't think you might face any difficulties.

To get more info abt CGI.pm here the direction.

Gently, I suggest that this would be more appropriately pursued in the CGI forum where there is a FAQ on such matters.

I disagree with goBoating. It's still a perl question. I'd guess that at least half of the post here are as much CGI-related as they are perl. I don't subscribe to the CGI forum because what I'm interested in are the perl-related questions, whether they are also CGI-related or not is irrelevant. I would assume that posts to the CGI forum had to do with the CGI INTERFACE spec, not the language used.

Maybe the FAQ mentioned should be posted to this forum as well?
