Perl is one of the most popular scripting languages for adding powerful interactive features to Web pages. Perl lets you place forms on your site that collect and process user input such as comments and product orders; enables visitors to search for information; and can integrate a database into your site, among its many other capabilities. Perl and CGI for the World Wide Web, 2nd Edition: Visual QuickStart Guide fully revised and updated since its original 1998 release, gets users to the core of CGI scripting with Perl. Even first-time programmers will be able to create useful, workable scripts from scratch, or adapt and customize existing scripts to their own needs. Hundreds of screen shots and clear, easy-to-understand directions make this the perfect Perl book for beginners, as well as a handy reference for those with previous programming experience.

The book consists of chapters that define forms, Scalars, Arrays, and Subroutines. The examples are functional, but not practical. For instance, a form that takes information and produces a simple result. She goes into no detail how the script processes that information to get that result. She often gives a line of code and skips the definition of it. It would have been nice if she explained what the code was thinking and how it decides to process information. Show subtle variations of the symbols will produce an entirely different result. Also, I wanted to see how I could construct a working program with several subroutines that has a practical purpose. That to me is "Interactive".
In summary, she does not give practical examples, she does not give explain the inner workings of how a script thinks, she does not inspire the creativity of the reader. She does give about 400 pretty pictures.
I was writing simple cgi's even before finishing the book. This afternoon, I wrote a cgi that takes input from a lengthy form, prints a confirmation/thank you html page to let the user know that their input was received, sends the parsed and formatted form data via email to the receiving party, and generates an include file that automatically updates an online html log that everyone in the company can see and track. Two weeks ago I couldn't have possibly done this. Honestly, I wouldn't even have known where to start.
No, this is not a complete Perl training manual, nor is it meant to be. But if you need to use Perl/CGI on the web to process forms and information, there is no better book on the market. I use it everyday and highly recommend it to everyone.
I just wanted to say Thanks! for teaching me HTML and PERL in your great to-cool-for-words Visual Quickstart Guides!
Next, I plan on buying RedHat Linux 6 and Illustrator 8 (the bookstore didn't have Linux 6 in, and when I had to choose between Photoshop 5, Illustrator 8 and PERL and CGI, well... the only real tough desision was Photoshop or Illustrator).
And one last thing, if you know C/C++, and havn't planned on writting a VQS Guide... then you should! After I finish your PERL and CGI book, I'd like to learn C and C++, but there are not any VQS Guides on the subject. After wasting 30 or 40 bucks on boring O'Reilly books that already assume you know some other language, don't explain all the steps of code, weight close to a ton, and have always left me utterly confused and frstrated, I've learned to stay away from them and stick to the colorful VQS Guides.
So thanks again! And again!
Admittedly, the coverage of the subject is a little light, and the hold-the-novice-user-by-the-hand- style was actually confusing (she should have used the more standard method of using bold, italics, and monospace fonts to indicate output, user required input, and variables) BUT considering I was at the absolute beginner level with respect to Perl and CGI, I feel the book lived up to my expectations. I wanted something to get me started quickly, and not to assume I knew anything about CGI and PERL but did assume that I knew HTML. I did not want a book that would cover the subject matter exhaustively, just give me a basic "Quick-Start" which it did quite well.
I continued to use the book as a reference for a few months, though it's really not laid out well for that purpose. (I would suggest the O'Reilly Perl CD Bookshelf for that) If you know PERL and CGI basics, this one is not for you, but if you're comfortable with HTML and want to start doing more, It's worth a try.
