The first half of the book is a great tutorial on using the CGI.pm module. There are all sorts of tricks, and Lincoln's explanations are very good. If you want a tutorial, this is it.

However, the reference section is a mess. It's not clear how the various functions are grouped, and there are no guides in page headings to tell you where you are as you thumb through. If you're looking for a desktop reference, you're probably better off using the CGI section of "Perl In A Nutshell".

Finally, the book looks like it was thrown together in Word, with no real thought about how it would look. Chapter titles are in grey: Why?

I rated this book as 5 stars, not because I can't see how it could be improved, but because the product it documents is so valuable, and the book is necessary to get full value from CGI.pm.

While the book's content mostly duplicates information which can be found at the CGI.pm web site, and/or in the CGI.pm source code, it does present it in a much more convenient manner, and seems to contain additional, valuable information.

I've used this book for a couple of months now, and wish to refute some of the criticism by other reviewers.

The example font is much less bold than the text, but I use reading glasses, and wouldn't even have noticed the lighter font, if it hadn't been pointed out to me in other reviews. Perhaps it doesn't photocopy well?

The reference section is a little confusing since it contains some subsections which, in turn, contain alphabetic organization, rather than being strictly alphabetic throughout. The book has a decent index, however, so this isn't a real problem. Besides the organization is beginning to make sense.

The book is not quite up-to-date with the product it documents, but publishing a book does have some turn around time after all. My boss and I could use another copy, we'll probably get one as soon as the next edition is available.

This is an invaluable book for using an invaluable library module (if you do CGI coding). There is absolutely no substitute for CGI.pm. However, this book is very frustrating to use because the Reference Guide section is organized into different weird categories instead of just listing all the functions in CGI.pm in alphabetical order (like in Perl books, for example). Therefore the reader has to try to figure out what category a function in the module belongs in in order to look it up. Very very aggravating! In fact I trained a group of developers in using CGI.pm and many of them avoided using it because it takes so long to find what you're looking for in the reference section of the book. I am hoping for a new edition of the book SOON with this problem corrected. The material is invaluable, but I have to give three stars because of poor organization.

This book is so easy to read and understand.

In about two days I was using cookies to maintain state, I have since writen a form mailer that puts data into csv, and a bunch of other cool stuff. EASY, a fast read, and you'll be able to jump right in and do a lot of cool stuff immediately.

This book will be an absolute necessity for CGI programmers writing in Perl. It's a description of a must-use tool by the tool's creator. It goes well beyond the online and POD documentation for CGI.pm. The example code snippets and programs are well chosen. There are a few problems: the organization of the reference section is confusing, and the descriptions of table(), Tr(), and td() don't explain how to enter attributes. (But the table examples show how to do that, so it's not much of a problem.) Summary: if you write CGI in Perl, get this book and use it.

I must confess that I could do virtually none of the programming that I do without Lincoln's fine work, but it's sometimes frustrating with so many broken examples.

Once you figure out the syntax, you'll be OK. There's a lot of easy-to-find reference. Make sure you test very small sections of code on their own and insert it into your programs when you get it working. Then refer to your working programs (copy & paste) when you make others.

Again, much credit needs to be given to Mr Stein, but Paul DuBois' Book MySql and Perl For The Web explains CGI.pm much better (you'll still need Stein's book if you're going to be serious about CGI) with examples that really,really, work, extreme attention to detail, and incredible organization.

I've enjoyed this latest book of Lincoln's, and recommend it highly. This is an interesting book with many good examples. I am happily using it as a text in my Programming the World Wide Web classes. This is one of very, very few books on CGI programming that use fluent Perl (Perl 5 constructs in particular) *and* up-to-date language features (CGI.pm, obviously). The only drawback of the book, and the only reason I didn't give it 5 stars, is that I think the typography is lousy. In particular, the font for the code samples is too light, and the excessive leading in general makes the book harder to read. The book has its share of first printing typos, but then again, mine had them too, so I can hardly complain about that. :-) Good work, Lincoln!

If you write CGI scripts in perl and are not taking advantage of cgi.pm, then you're doing things the hard way. Written to take the tedium out of scripting, the module allows you to use easy to remember shortcuts to code some of the more difficult things in perl. Cookie setting and retrival is a snap, as is allowing users to upload files, and more. For advanced programmers, the object oriented method is supported and also very easy to use.

The book is easy to follow and contains some illustrative examples that are also available on a companion website. My one and only complaint is the price of the book: it seems a little steep given that most of the material in there is available on the web in one form or another for free. If you don't want to take the time printing and compiling, then this is an excellent manual that will soon sport bookmarks and highlights throughout.

The Offical Guide to Programming with CGI is an introductory level text covering Lincoln Stein's CGI.pm module. CGI.pm is the standard perl module for working with CGI. CGI (Common Gateway Interface) is the standard interface by which external programs can interace with web servers. The text assumes the reader has at least a beginner's knowledge of Perl and HTML. For instance, readers are assumed to know how to use modules, but no prior knowledge of object oriented perl is required. Likewise, the reader should have a passing familiarity with HTML tags, forms in particular. This book is particularly beginner friendly.

The reader should be able to walk away from the book with the ability to create simple websites which take and respond to user input. The potential CGI.pm programmer will gain a fundamental knowledge of the module, its interface, and how it may be used to generate HTML. The text also includes a very detailed reference guide which may appeal to those people who prefer to hold what they're reading.

While the book was published back in 1998, it hasn't become outdated. It is pleasantly surprising that CGI.pm's interface has changed so little. Support for new standards like XHTML have been added since the book was originally published, but have had little net effect on the use of CGI.pm itself.

Why CGI? Isn't that the way people used to write dynamic web pages? Yes. And where portability concerns outweigh performance, it still is. Also, if you're a relative novice or don't have an endless supply of round tuits, CGI programming may present the lowest barrier of entry into dynamic web programming.

Even if you later move on to one of the newer templating systems a fundamental knowledge of CGI.pm and how it works will still be useful. Not to mention that some of the templating systems for instance HTML::Mason will run on top of CGI, even though most are primarily designed to work with Apache and mod_perl. For those who would appreciate a short description of what mod_perl is, it basically puts a copy of Perl inside the Apache executable making powerful hooks available to perl scripts and avoiding the overhead of executing a separate process for each CGI script.

The author of the book, Lincoln Stein, is also the author of the module itself. In the book, Stein takes the reader through a gradual progression of scenarios and solutions. The explanations are thorough and the pace gradually takes the reader into more advanced topics. In short, it is a concise introduction to CGI programming with Perl.

Low level details, like how CGI works under the hood and more advanced topics like security, cascading style sheets, javascript, and persistence are touched upon but not covered in particular depth. The author does however provide many timely references to books and websites where the reader can find more information on those topics.

The author has done a wonderful job of explaining how to use the CGIpm module. If you understand the basics of perl, you should be able to go through the bulk of this book. And with just a slight acquaintance with Perl references and anonmous list, you'll be surprised how quick and easy this is to master. This book puts other CGI books to shame because other books shy away from discussing all the cool functions in CGI.pm.
