Perl - Form handler

J

John

Dear all,

It been more than 3 days I am trying to debug this program, I
interpret it using activePerl and it is giving (perl -wc
code_process.pl) no error syntax but when I put it online, change to
the appropriate mode and test the html form it gave me an 500 internel
server error.

I really need it to be done soon, I would not post here before I test
it as much as I can,

In case you would like to check the html too, please let me know.

regards,
John

What does the server's error log tell you? If you can't access it, you
can add this line in the beginning of the script so as to have fatal
errors printed to the screen:

use CGI::Carp 'fatalsToBrowser';
In case you would like to check the html too, please let me know.

To be honest, I don't want to dig into the details in that program,
since it's old and not very good according to today's standards.

I can give you the standard advice for these types of problems:

1. Run the CGI on the command-line (but you have already done this).
2. Look at the server error logs; what do they say?
3. Use the CGI module; don't try to parse form input yourself.
4. Put "use CGI::Carp 'fatalsToBrowser';" in your program (after doing
3)
5. Minimize your program to attempt to isolate the problem and post
that minimal program, what it is doing, what the server logs say, if
anything, and what you expect it to be doing that it is not.

FYI: this newsgroup is defunct; try comp.lang.perl.misc in the future.
