Trouble Shooting Failed to query database. online 82

[telsiin]

This is a piece of code from RPG WEB profiler \tarlen\profiler\public_profiler\register.php

http://lordofansalon.no-ip.org/tarlen/profiler/public_profiler/index.php for testing

 

 

Now I don't believe there is anything wrong with this code as the whole application is available free from http://sourceforge.net/project/showfiles.php?group_id=167472

 

But I have a few question

1 what is the purpose of "->"

2 what setting on my computer could be causing this error

 

    // Check to see if the profile name already exists.

    $_r = $rpgDB->query(sprintf("SELECT COUNT(pname) as cnt FROM '%s' WHERE pname = '%s'",

      $TABLE_USERS,

      addslashes($user)));

    if (!$_r)

//line 82//    __printFatalErr("Failed to query database.", __LINE__, __FILE__);

    $r = $rpgDB->fetch_row($_r);

    if ($r['cnt'] != 0)quote]

 

 

As alway thank you for your help

I found the source code that causing the query to fail in page db.php

The file that I need is system.php  which has the Database connection information

 

However I can't the require_once function to work correctly

The file is located in

<Directory "/home/tarlen/profiler/root_profiler/system.php>

 

and is being call from

<Directory "/home/tarlen/profiler/root_profiler/engine/db.php>

 

 

I have also try to use an alias but it still didn't work

Alias /profile "/home/tarlen/profiler/root_profiler"

    <Directory "/home/tarlen/profiler/root_profiler">

        AllowOverride All

        Order allow,deny

        Allow from all

    </Directory>

 

<?php

  // db.php

 

  // Opens a connection to the database.

 

  if (defined('_DB_INCLUDED_'))

    return;

  define ('_DB_INCLUDED_', true, true);

 

    require_once(dirname(__FILE__) . '/../system.php');

    require_once(dirname(__FILE__) . '/../error.php');

 

  //require_once "/profile/system.php";

  //require_once "/profile/error.php";
