Access denied for user 'ODBC'@'localhost'

Hello Everyone,

I'm facing a problem and I would like to seek your help. I have downloaded a opensource php application to run on our company intranet. First I would like to provide my complete environment details.

WAMP Server 2.0i
Php V 5.2.7 (downgraded from 5.3.0 to get rid off ereg deprecated errors)
My SQL 5.1.36
OS - Windows Server 2003 R2
Port - 8080 (80 is used by IIS)

I have setup 3 applications on my wampserver(Timesheet/Joomla/Facility Booking) . All the three apps are running well on my server. I have created 3 different users and 3 different databases.

However, my Timesheet application is not running from other computer in our network. Well it's running but not able to connect to database. I mentioned the warnings and notices below. I'm able to login to the phpmyadmin from other computer to that database. So I feel the problem is with php source code. I have never worked on php before and your help is much appreciated.

I think there is no problem with apache or my sql as I don't see any errors related to this. These are from php error log which are displayed when I access the app.

I have attached all files related. Sorry for long post this thing is driving me nuts since a week. Thanks in advance. Have a great weekend.

Well the PHP is crap because it's not handling errors very well, this is true, but the actual problem isn't the PHP code, it's the connection to the database and/or the database user.

Yes, I showed it to one of my friend and he has same opinion about the code.

Header.php is the file which is handling DB connection. Can anyone comment on the header.php code ? Is is well programmed ?

Change the connection and it should work.

One of the user at other forum pointed out that the problem is with these lines in header.php

// grab the connecting IP address. //
$connecting_ip = get_ipaddress();
if (empty($connecting_ip)) {
return FALSE;
}


The function get_ipaddress is defined as below in functions.php

function get_ipaddress() {

if (empty($REMOTE_ADDR)) {
if (!empty($_SERVER) && isset($_SERVER['REMOTE_ADDR'])) {
$REMOTE_ADDR = $_SERVER['REMOTE_ADDR'];
}

$REMOTE_ADDR = getenv('REMOTE_ADDR');

$HTTP_X_FORWARDED_FOR = $_SERVER['HTTP_X_FORWARDED_FOR'];

else if (!empty($_ENV) && isset($_ENV['HTTP_X_FORWARDED_FOR'])) {
$HTTP_X_FORWARDED_FOR = $_ENV['HTTP_X_FORWARDED_FOR'];
}
else if (@getenv('HTTP_X_FORWARDED_FOR')) {
$HTTP_X_FORWARDED_FOR = getenv('HTTP_X_FORWARDED_FOR');
}
}

return $regs[0];

// information about the true IP

}
}
}


Can anyone please help me to clean up this code ?
