Need error.php added to my code

[KiXeN]

Need Some help adding a error.php to load when a page isn't found like if somone trys going to a link that isn't found I wanna have it use the error.php file I have on my server but using my below code...

 <?php
if(isset($_GET['home'])){
include('main.php');
}else if(isset($_GET['downloads'])){
include('downloads.php');
}else if(isset($_GET['donate'])){
include('donate.php');
}else if(isset($_GET['links'])){
include('links.php');
}else if(isset($_GET['contactme'])){
include('contact.php');
} else {
include('main.php');
}
?>

How would I add the error.php to be showen when someone clicks on a page that isn't on the server.

You can throw the $_GET you use into an array, and then check the query string (ie. domain.com/?this) against it, like this:

$pages = array("home","downloads","donate","links","contactme");

$queries = split('[=.&]',$_SERVER['QUERY_STRING']); 

// If $queries[0] is not in our array 

if (!(in_array($queries[0],$pages))){ 
include('error.php'); 
} 

// If $queries[0] is in our array, include file according to GET 

elseif (in_array($queries[0],$pages)) 
{ 
  if(isset($_GET['home'])){ 
  include('main.php'); 
  } 
  elseif(isset($_GET['downloads'])){ 
  include('downloads.php'); 
  } 
  elseif(isset($_GET['donate'])){ 
  include('donate.php'); 
  } 
  elseif(isset($_GET['links'])){ 
  include('links.php'); 
  } 
  elseif(isset($_GET['contactme'])){ 
  include('contact.php'); 
  } 
  else{ 
  include('main.php'); 
  } 
}

You can also just make it easy for yourself. If the file exists, include it; if not, error. Only thing you'll have to worry about is that your links point to files that exist.

$query=split('[=.&]',$_SERVER['QUERY_STRING']);
$file=$query[0].'.php';
// If file exists, include it:
if(file_exists($file)) include $file;
// If not, try again:
else include 'error.php';
