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.

Product Description
From the Author
When I started learning Perl I found it really frustrating that most books assumed that I was a programmer. They used terms I'd never heard of and didn't explain particular functions because they "worked the same as in C". Aargh! And most of them didn't care about using Perl on the Web. I did.
So, when I wrote this book, I made sure to start at the beginning. It'll give you everything you need to know to write your own Perl scripts that process the information that people send you through your forms. And it does it visually. You'll _see_ each script, the HTML page that it interacts with, and the result of using the Perl function in question. You'll actually understand what you're doing.
I don't want to waste your time. If you already know how to program, this is probably not the book for you. If you're looking for an exhaustive reference on Perl that gives you every detail on every last function, this is not it. And if you don't care about using Perl for Web pages, you should not buy my book.
On the other hand, if you've never programmed before, this book will give you a peek inside the "programmers-only" club so you can see what's going on in there. If you want to add a guestbook or a counter to your Web page but don't know exactly where to start, this is the book for you. If you want to know to know why a script does what it does and then learn to customize it for your own use, this book will help you do just that.
I also take a very few pages to show you how to create a form, even though most of you already know how to do that, because the way you use NAME and VALUE attributes is really important when you start writing Perl scripts. And there's a special appendix that covers basic Unix functions so you'll have everything you need to get started. The book's website includes a Question and Answer board, downloadable files that include all of the example scripts and accompanying HTML documents, and readers' comments. I'm also planning a section where folks can share and show off their scripts. I look forward to seeing you there. --This text refers to an out of print or unavailable edition of this title.

The first edition of this book was very much in that camp. The Perl you learnt from it was terrible. The second edition is much better. It now includes a number of acknowledged Perl "best practices" that other books ignore, including "use strict", "-wT" and "CGI.pm".
My problem is that whilst it uses these features, I don't think it really explains _why_ you should use them. It all sounds a bit too close to "cargo-cult" programming to me (where you program simply by copying existing code, you don't make any effort to understand what's going on).
If you want a simple introduction to programming in Perl to write CGI programs then this book is head and shoulders above any of its competitors. However, if you want to understand more about Perl and CGI then you've be better off reading "Elements of Programming with Perl" following by "CGI Programming with Perl".
Certainly an excellent beginners book, but still useful for general reference one you know what you are doing!
It made me wonder does the author think that we already know html, I know I already do, but not everybody does so if you are a beginner then you are totally stuck, as she does not include the documentation for the webs pages where you gather the data from.
I like how the code is seperate from the main text as it is easier to find like that, but that is about all.
So to sum it up, I think if you already know Perl and just want a reference book than this is fine for you, but if you are a beginer to Perl then you should consider some other book.
I came from a C background and was amazed how quickly the author was able to put the pieces of the puzzle together for me.
While she skipped over large areas and didn't cloud issues with obnoxious synonyms of the perl language I understood the basics enough that when I need that simple unanswered question I only need to look on the Net.
I will be eternally grateful for E Castro and her marvellous book! Thank you.
The book's excellent side by side comparisons between the perl code and what it actually does... Read more
