Dynamic pages is a term that means web pages generated on the fly by a
scripting language in response to a condition.
Example : user bob fills in a request form on a web page . When he submits
it a script generates an new page based on what bob sumited. As most folks
here use Perl as the scripting language creating dynamic pages is a process
of useing Perl scripting on a web server.
To start read the manual pages to CGI.pm to get an idea of how powerful it
can be.
The most simple of dynamic pages consits of a web page wriitten in HTML that
consist of a form that calls a Perl script opon submission. The Perl script
generate the new HTML and passes it back to the web browser.
# demo of dynamic page creation
you can use Perl or HTML to create the calling page , I'll use HTML for this
example.
<html>
<head>
<title>Demo</title>
</head>
<body>
<form action ="/cgi-bin/demo.pl" METHOD="POST">
Select a suprise level<p>
<SELECT NAME ="selection" >
<OPTION SELECTED>big</OPTION>
<OPTION>small</OPTION>
</SELECT>
<p>
Rember to press the submit button for your suprise !!!
<INPUT TYPE="submit" NAME="submit">
</form>
</body>
</html>
# now we generate a page on the web server based on what was selected
# demo.pl
use strict;
use CGI;
my $q=new CGI;
my $choice = q->param( "selection" );
if($choice eq "big"){
print $q->header("text/html"),
$q->start_html( "BIG SUPRISE"),
$q->p( "You have been elected as leader of the earth !"),
$q->end_html;
}
if($choice eq "small"){
print $q->header("text/html"),
$q->start_html( "SMALL SUPRISE"),
$q->p( " Look inside that cracker jaxs box I think you won a prize"),
$q->end_html;
}
You see based on whats selected a "Dynamic" page is created and returned to
the web browser to display
hope this gets you going
