I've just started learning perl.
I have a file called read_art.pl which takes a parameter for the name of the
file and reads the article. i want to have a rate this article link which
rates it. for that, i plan to write a file, say rateit.pl now, when i click
on rate it, it will call the perl file, say as, rateit.pl?val=2 (2 is the
name of the article file). this file (rateit.pl) will contain the form
required to rate it. now i want the same file to create the form and do the
rating. that means that when i rate, it will call rateit.pl?val=2&rating=5.
so, how do i make the same pl file distinguish the two diff calls?
Also, what is "use CGI"? Seems similar to creating an object of a class in
C++. Where do i get info on the various functions in CGI?
Thanx in advance.
