I have to write a perl script for class. I had to learn Perl on my own, so I'm just getting into it. I have a book that goes through on how to complete a GuestBook for a website. The final assignment is going to be a Wedding Registry, but I figure if I can get the GuestBook completed, I can modify it with no problems.

Perl works correctly on my host, so I know there isn't an issue with that. I just can't figure out why I've copied everything from the book, yet it doesn't work.

The current script is located at http://www.lanceselgo.com/book.html Currently all it does is show the form, and you can submit it. (Supposedly) I don't have the viewing of the guestbook done yet because I haven't been able to get around this first problem.

The code can be downloaded at: http://www.lanceselgo.com/guestbook_ls.zip

I didn't know if it would be easier to download it, or make this post really big.

I have chmod'd the script to 755, and that's about all I can say. I don't have a clue what to try next. Thanks in advance.

Hey Lance,

You have a case problem on line 56 in addguest.pl:

Code:

    &HTML_Header ("All done!");

    # Should be:
    &HTML_header ("All done!");

If you have access to your error logs, you can usually find the exact error there. It takes a while to figure out what some of the messages mean but you get used to it real fast If not, a handy tool is CGI::Carp. Just add the following line to your script somewhere under the shebang line:

Code:

#!/usr/bin/perl -w
use CGI::Carp qw/fatalsToBrowser/;

That will send the errors to the browser in addition to the error log.

See the CGI::Carp pod for more details and features.

Thanks a lot Charlie, I'll try that out. I'm very new to Perl so I'm not all with it. I appreciate your generous response.

No problem, Lance. Let me know if you run into any more troubles.

I'm very new to Perl...

Everybody has to start somewhere. I've been there (I'm still there in some aspects), I know how you feel

In addition to Chas's suggestion:

500 internal error can be from:

incorrect path to perl, which is the first line of the script

Script is uploaded in binary mode instead of ASCII mode

The script istrying to print something to the screen before printing an HTTP header

any syntax error will also crash a Perl script
