on
the webserver ive got ... (in php)
Quote:
<?php
$filename
= "userlog.dta";
$search = $_GET["search"];
$user_data =
file($filename);
// trim whitespace from the
strings
for($x = 0; $x < count($user_data);
$x++)
{
$user_data[$x] = trim($user_data[$x]);
}
// see
if its in the file
$on_list =
array_search($search,$user_data);
if ($on_list != "")
{
echo "on list";
}
// if its not write the name in the
file
else
{
$fp = fopen($filename,"a");
// if your
server cannot access the file error
// almomst any php server can
make a file if one does not exist
// even if your server will not
create a file for you
// you can place an empty file for the
script to use
// you really have to screw up to get this
error
if(!$fp)
{
echo "Error: Cannot open
file.";
exit;
}
fwrite($fp,$search."\n");
fclose($fp);
echo
"new user
added";
}
?>

now the
only security is the fact noone knows exactly where to look (till now) and
if this still existed on my website there would be nothing to stop anyone
from putting
cheesefactory.us/searchdata.php?search=Osgeld
Barmy
or
cheesefactory.us/searchdata.php?search=JACK ASS
into their browser and adding something to my text file so this is
very simplistic and totally unadvised for anything but a learning
experiance
