Re: Re: Reading form data and printing variables using CGI.pm

But how does the variable become associated to the HTML line? 'is the value of $Firstname', Thanks



<code>
#!/usr/local/bin/perl -w
use strict;
use diagnostics;
use CGI qw(:standard);
my $Firstname = param('Firstname');

print header(), 
        start_html(-title=>"CGI.pm Example Script"), 
                                 h1('Hello World!'), 
                       'is the value of $Firstname', 
        end_html(); 

exit (0);

Greetings cal, In Perl, using a single quote simply reads a string literally, but a double quote interprets a string. In your code, you have single quotes around the string where you use $Firstname. So what gets printed is literally "$Firstname". You actually want Perl to interpret the variable, so... `print header(), start_html( -title => 'CGI.pm Example Script'), h1('Hello World!'), "is the value of $Firstname", end_html();` [download] -gryphon code('Perl') \|\| die;	[reply] [d/l]
