Question

I am adapting some scripts that I found through Google that monitor users who login in to a website.

This consists of including this in each page I want to monitor:

<?
include_once("config.php"); 
include_once("functions.php"); 
?>

config.php looks like this (I have removed info on actual database):

<?php 
      DEFINE ('DB_USER', '');// database username 
      DEFINE ('DB_PASSWORD', '');//database password 
      DEFINE ('DB_HOST', '');//database host, usually localhost 
      DEFINE ('DB_NAME', '');//and finally the database name 
      $dbc = @mysql_connect (DB_HOST, DB_USER, DB_PASSWORD) OR die ('Could not connect to MySQL: ' . mysql_error()); 
      @mysql_select_db (DB_NAME) OR die('Could not select the database: ' . mysql_error() ); 
?>

functions.php looks like this:

<?php 
$page = $_SERVER['PHP_SELF']; 
$user = $_SESSION["name"];
$logq = "INSERT INTO logs (Name, Page, Date) VALUES ('$user', '$page', NOW())"; 
$logr = @mysql_query($logq); 
?>

This works fine, i.e. the table in my database is populated correctly.

However the file that is supposed to generate a table on a webpage to show the information in the MySQL table isn’t working. The file, logs.php, looks like this:

<?php 
      $lq = "SELECT id, Name, Page, DATE_FORMAT(date, '%d %M, %Y') as sd FROM logs ORDER BY id DESC LIMIT 50"; 
      $lr = @mysql_query($lq); 

      if($lr){ 
      echo "<table><th>Name</th><th>Page</th><th>Date</th>"; 
      while($lf = mysql_fetch_array($lr, MYSQL_ASSOC)){ 
      echo "<tr><td>" . $lf['Name'] . "</td><td>" . $lf['Page'] . "</td><td>" . $lf['sd'] . "</td></tr>"; 
      } 
      echo "</table>"; 
      } 
      else 
      { 
      echo "No results!"; 
      } 
?>

Even though there is data in the MySQL table I am always getting just ‘No results!’ showing when I browse to the page.

Can anyone see what the problem is?

Perhaps you don’t have a db connection in logs.php? If your code is the full file then this should be the problem.
If so, just include config.php at the top of the page.
