Variable Error?

[Lol5916]

Here's the error:

Notice: Undefined index: HTTP_REFERER in /home/*******/public_html/******/referer2.php on line 5

 

Script is:

<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
$line = ('------------------------------------------'); 
$ref = $_SERVER['HTTP_REFERER']; 
$ip = $_SERVER['REMOTE_ADDR'];
$d = date('l dS \of F Y h:i:s A');
$mes = '<br>Referer: '.$ref."<br>";
$mes = 'IP: '.$ip."<br>";
$mes = "Date & Time: ".$d."<br>";
$mes = ".$line.";  
$file = "logger.html";
$fh = fopen($file, "a");
fwrite ($fh, "$mes\n"); fclose($fh);

?>

 

What's the problem?

[shedokan]

maybe it's because no page has reffered to this one.

try to make a page which redirects to that page and see whether it's the problem or not.

Nope, that's not the problem.

This is not an error but a notice only, and there are ways to turn them off if you want.  Depends on how tidy you want your code to be, of course.

 

Before you refer to the value in the array, you need to check if it is set.  Not all user agents set the value for $_SERVER['HTTP_REFERER'].
