Re: Best Practices: CGI.pm & CSS2 ???
CSS is not deprecated. It is not reliable for positioning but it is quite
usable for defining text and character styles. If you have ever
changed all the font tags in a web site, you will be a CSS fan.
If you attempt to validate your HTML against w3.org's validator, you
are required to be a fan.
http://validator.w3.org/
It is probably not a good idea to use CGI.pm to produce HTML output. Why
learn another HTML syntax ? Something like HTML::Template or even a HERE
document will serve you better.
However it is very foolish to **Not** use CGI to parse input from a form.
It is much, much easier and safer than parsing the raw query string or
reading STDIN or escaping shell charactors or otherwise doing the job by
hand.
#!/usr/bin/perl -wT
use strict;
use CGI;
use CGI::Carp;
my $q = new CGI;
my $name = $q->param('first_name') || 0;
my $result = <<HERE;
Content-Type: text/html; charset=ISO-8859-1\n\n
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html>
<head><title>Hello $name</title></head>
<body><p>hello $name</p> </body>
HERE
if ($name) {
print $result;
}
else {
print <DATA>;
}
# see perldoc perldata for __DATA__ file handle info
__DATA__
Content-Type: text/html; charset=ISO-8859-1
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

</head>
<body>
<form action="/cgi-bin/foo.pl" method="get">
<p>Name:<input type="text" name="first_name"></input></p>
<p><input type="submit"></input></p>
</form>
</body>
</html>
