Converting from hex string to ascii string - reading post data	Can't Post

I'm having difficulty reading post data and converting it into the ascii representation of the string
The main issue is that in the following code the variable $value still has non alphanumerical characters such as %3D that is the equal sign. I'm not sure how to make these ascii characters.

Code

foreach $pair (@pairs) 
{ 
	($name, $value) = split(/=/, $pair, 2); 
	$value =~ tr/+/ /; 
	$value =~ s/%(..)/pack("C", hex($1))/eg; 
	#print "<b>$name:</b> $value<br />"; 
	$FORM{$name} = $value; 
}

Don't manually parse the html form submission yourself. Use the CGI module.

Code

use strict; 
use warnings; 
use CGI; 
 
my $cgi = CGI->new; 
 
# this line replaces your foreach loop and does it properly for both POST and GET submissions. 
my %form = $cgi->Vars;
