I agree with everything Chmrr and $code or die said. Caution and prudence is absolutely necessary when selecting a script.
$code or die", thank you for noticing that at least some decent stuff was in there (although they are pretty much buried in the bad stuff). Special pains were taken to try and include as much exemplary work as possible. Somewhat understandably, the authors of these excellent scripts don't seem to add their listing to any script resource type sites. So when I see them, I add them myself. However, I'll be more cautious in blanketly recommending a resource site as a first step in the future.
Chmrr, thank you for pointing out merlynís column. I agree that his Web Techniques column is one of the first places a person should start looking for a solid CGI script. To his credit, Chmrr was already either aware of the specific article or took the time to look (my bad for neither Ė my apologies to Anonymous Monk).
Which brings me to a rather amusing story in itself. On various occasions, I recommended merlynís Web Techniques columns to people asking for an excellent program that does x. One person in particular admitted precious little knowledge of Perl programming. After he read the recommended column, I offered basic instructions on how to install the file. He was excited and thanked me profusely.
The next day, I received a frantic email asking what the following meant:
He simply copied the code from the column (line numbers included) and uploaded it. Yes, this was for real :)
Perhaps the moral of this story was that I should have given the guy both the column and column listing urls (the code listing isnít linked from the column, only from the WT home page).
So, Anonymous Monk, the code that Chmrr (and now, I) recommend is at http://www.stonehenge.com/merlyn/WebTechniques/col05.listing.txt. The column discussing the program is at http://www.stonehenge.com/merlyn/WebTechniques/col05.html.
