All I want is a code that can accept an input from a html form and ammend those inputs to a data file. Below is the code that I am using to accept the inputs.

#!/usr/bin/perl

print "Content-type:text/html\n\n";

read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
@pairs = split(/&/, $buffer);
foreach $pair (@pairs) {
($name, $value) = split(/=/, $pair);
$value =~ tr/+/ /;
$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$FORM{$name} = $value;
}

print "<html><head><title>Form Output</title></head><body>";
print "<h2>Results from FORM post</h2>\n";

foreach $key (keys(%FORM)) {
print "$key = $FORM{$key}<br>";
}

print "</body></html>";

what else would i need to add to open the data file and print the inputs into that file. If I need to post the html that I am using also I will do that.

Also I am having trouble finding a free host were I could test these files. Could anyone recommend me to a good host.

As for the latter, there are free hosts that allow CGI, including writing to files. I can't remember the entire list now, but here are a couple:

http://www.netfirms.com/
They put a banner on top of every page and block sendmail after a few posts.

http://www.portland.co.uk/
No ads. No sendmail. Only 100 MB monthly data transfer, which is enough if you only want to test the scripts.

I haven't tried them yet, so I'm not sure how they handle writing to files, but I hear they are excellent for a free host. I think they place some link-back button on the buttom of your page. No sendmail.

As you can see, the real problem is finding a host that doesn't ban sendmail. I haven't found one yet.

As for the code, try this link:

It deals also with reading and writing data file.

i use tripod, it works great, but you have to have the right script to go along with it

http://www.tripod.com

i have created a script with multiple functions which make it millions of times ezer to get info from forms and links.

the first is the param() function.

if an input's name is "monkey" (<input type="text" name="monkey">)

then to get the value you simply write

$monkey = param('monkey');

it is really simple!

next is the cookie() function.

it is used for getting data from a cookie.

if a cookie is set to:

print "Set-Cookie:monkey=$monkey\n";

then you get the value by writing:

$monkey = cookie('monkey');

simple, right.

it also has header and footer and error functions, but i wont go into those for now.

to get this, goto

http://benastan.tripod.com/cgi-bin/ben.lib

view the source, take out the stupid pop up add script, and save it as "ben.lib" (plz i spent alot of time making it!!!).

its really helpful for me

if it doesnt help you, well, then ive wasted my time
either way, its ok...
