Smart404

[timtamboy63]

Hey guys, I just finished coding my "smart" 404 script and I thought i'd release it.

Release for www.chrixel.com (a awesome web coding and design forum) but I thought i'd post it here and hopefully get chrixel a bit of traffic

Heres the contents of the readme in there because I really can't be bothered to type it up again

################################################## ################
Smart404 Script, created by timtamboy63 for released for www.chrixel.com
################################################## ################

IMPORTANT NOTE:
This will only work if you have apache as it utilises the .htaccess file.
If you are on another web server but can redirect the 404 page, then you must redirect to:
/smart404/404.php


Usage:
If you don't already have a htaccess, just extract the smart404.zip to your the root of your
webspace(www or htdocs normally).

If you do have a .htaccess file set up, upload the smart404 folder to the root of your webspace and add the
following line to your htaccess

ErrorDocument 404 /smart404/404.php

NOTE: This will remove any custom 404 page you may have set up, but its fairly easy to get that back if you
know basic php.


What this script does:
Lets say you have a document called yay.php
You link a friend to it but they type in yay.html
Now normally they would get an error page, but with this script, they get redirected to yay.php
How smart!

Whats more, this takes the type of file into account.
For example, if you have test.php and test.wav, and someone types in test.mp3, chances are they're looking for
the test.mp3(they're both audio files) and so it redirects them to the test.mp3

Here's the code if anyone's interested but really can't be bothered downloading:

error_reporting(E_ALL);

  $pageURL .= $_SERVER["SERVER_NAME"];
 }
 return $pageURL;
}

//this function checks whether there is a file of the same name & extension in the array Data

That's only the php, you'de also need the .htaccess modification obviously

You can get the download over at chrixel, its upped to mediafire so you don't need to register: http://chrixel.com/forums/index.php?...page__pid__917
