This is the documentation by the author of CGI.pm, Lincoln Stein, he also wrote a book on his module called "Official Guide to Programming with CGI.pm" ... Hope this helps.

Hmmm.....

Typically I am not a MS fan but Front Page 97, 98 and 2000 all provide this functionality with a little copy paste action. Build your object in a GUI and copy the HTML into your "favorite text editor." I have been using extensively with DBI and Mysql DBD. Just choose the chunk of HTML that you want to loop and that is about the only time you will type "print". Just use:

print <<ENDHTML;

ENDHTML

to wrap you FP HTML and all is good.

Useful Intro

I found this very useful introduction to CGI.pm. I was looking all over the web for a very simple intro, and this was perfect. I think I now have enough information to get my feet wet.

Thanks............

CGI vs CGI.pm

Comming from a programmers point of view... already familiar with programming language and syntax... this all must make sense and probably helps to transform cumbersome HTML into a more familiar package.

However from the point of view of someone who has struggled to learn basic HTML and has built a few personal homepages in HTML and otherwise knows nothing about programming languagees, syntax etc. it seems unduely complicated and redundant.

typing:

Code:

print "<html><head><title> MY PAGE </title></head><body>\n";

seems relatively straightforward and familiar to. I've done it a hundred times.

Now I need to forget what I already know and learn to write:

Code:

use CGI qw(:standard);

or maybe:

Code:

use CGI qw(:all);

and:

Code:

print header(); 
print start_html(-title=>'MY PAGE');

which is fine... but completely unfamiliar and incomprehensible in terms of standard HTML
also what is the point of using:

Code:

print br(), hr();

rather than

Code:

print "<br><hr>";

and

Code:

print end_html();

does't even save a keystroke over:

Code:

print "</html>";

why learn to use a code that you don't know just to generate a code that you already DO know when you can just use the cade that you already know in the first place?

I'm sure from the top down this makes sense... but from the bottom up it seems rather redundant.

If I alreay have a website with the HTML written out I can just paste the familiar HTML code into the CGI script to create a new CGI generated page that looks identical to my old HTML website... but If I have to covert to CGI.pm it seems I have to completely relearn and rewrite every inch of every line of code from scratch.

It seems something like trying to study Greek so I can use Greek "shorthand" to translate the Greek back into English.

That is probobly a good thing to learn Greek Shorthand(CGI.pm) for translating Greek(CGI) into English(HTML) if you already know Greek... but not such a good thing if you only know English.

image help?

Hi: I'm running SuSE7.1, Konqueror, and Apache-1.3.14. The cgi script for uploading picture_file prints out binary code for the image. What needs to be added to print image? I can create a perl code script, run it from cgi-bin, and print out image, if I add print "Content-type: image/PNG\n\n"; at the top of my script. Is there something similar in CGI.pm? Thanks, Tom

Re: image help?

Yes, just type:

print header(-type => "image/png");

You can do this with any Content-Type you want too. =)
