cgi perl : I cant get perl to append my html file...

the_y_man · 03-20-2004, 10:06 PM

alright...i know this is not game related but i need some help concerning perl

basically i'm trying to get my perl script to post some text to and html file, when i access it from command line, it works, but when i have it executed through the web it doesnt work (i'm running slackware 9.1, kernel 2.6.4, apache, 1.3.29)
this is my code:

Code:

!/usr/bin/perl -w
#
require "cgi-lib.pl";

&ReadParse (*input);

$file='/usr/local/apache/htdocs/index.html';

open(INFO, ">>$file") or die ("failed to open file: &!");

print INFO '<table cellspacing="1" cellpadding="5" border="0" bgcolor="#000000">';
print INFO '<TR bgcolor="#EEEEEE" ><td height="130" width="100" align="center" valign="top"> Picture goes here<br>Name</td>';

print INFO '<TD rowspan="2" width="870"  valign="top" >';
$sFormInput = $input{'TextPost'};
print INFO $sFormInput;
print INFO '</table>';
print INFO '</br>';

close(INFO);

this is my error log entry when i have it run through the web:

Code:

print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 10
print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 11
print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 13
print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 15
print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 16
print() on closed filehandle INFO at /usr/local/apache/cgi-bin/newpost.pl line 17

the perl script works fine when i execute it through the server's bash shell.

i tried chmod +x index.html
i even tried (under /usr/local/apache) chmod 755 htdocs

no change in the error message

by the way, this is the error i get through the web, when i try to execute

Code:

can anybody help?

An error message like that usually indicates:
1. A syntax error, or
2. That the file does not have execute permissions

Shouldn't that very first line be #!/usr/bin/perl not !/usr/bin/perl?

You can post any sort of GNU/Linux software development questions here, not just game programming.

the index.html should be writable for the server user so chmod 0755 would not be the soultion but
chmod 0666 index.html
but it might be related to the servers configuration in respect of execution of cgi scripts, too. do other cgi programs run on that server? apache comes with a detailed documentation on cgi issues.
