****No longer works in WP 3.0****
So I had a teacher who really wanted to use the Arras theme with their class. Unfortunately, it didn’t play nicely with WPMU.
I tinkered for a couple of hours and I think that I have a semi-workable solution.
Basically, I did two things:
- I added the necessary WP includes so that you can use all of the regular WPMU functions.
- I added some logic that made it work with a multiple blog setup.
***I am not a programmer by trade, so there may be major mistakes in my logic. Hopefully this will help you get started. ***
First, I added the WPMU includes to the top of the /library/timthumb.php
[code]
include('../../../../wp-blog-header.php');
include('../../../../wp-includes/general-template.php');
[/code]
This made it possible to use regular WPMU function calls.
Next, I went down to line 520 and added some code to the function using WPMU functions.
[code]
/**
* tidy up the image source url
*/
function cleanSource($src) {
//Added Globals for functions
global $current_blog, $current_site;
// remove slash from start of string
if(strpos($src, "/") == 0) {
$src = substr($src, -(strlen($src) - 1));
}
// remove http/ https/ ftp
$src = preg_replace("/^((ht|f)tp(s|):\/\/)/i", "", $src);
// remove domain name from the source url
//Changed path logic
$path = $current_blog->path;
$path = str_replace("/", "", $path);
$host = $_SERVER["HTTP_HOST"]. '/'. $path ;
$src = str_replace($host, "", $src);
//Added blogs.dir logic
$src = str_replace("/files/", "blogs.dir/". $current_blog->blog_id . "/files/", $src);
$host = str_replace("www.", "", $host);
$src = str_replace($host, "", $src);
// don't allow users the ability to use '../'
// in order to gain access to files below document root
// src should be specified relative to document root like:
// src=images/img.jpg or src=/images/img.jpg
// not like:
// src=../images/img.jpg
$src = preg_replace("/\.\.+\//", "", $src);
//print_r($_SERVER);
// get path to image on file system. Changed from original.
$src = $_SERVER['DOCUMENT_ROOT'] . '/wp-content/'. $src;
return $src;
// get path to image on file system. Appended 10/4
if ($current_blog->blog_id == 1) {
$src = $_SERVER['DOCUMENT_ROOT'] . '/wp-content/blogs.dir/1/'. $src;
return $src;
}else{
$src = $_SERVER['DOCUMENT_ROOT'] . '/wp-content/'. $src;
return $src;
}
}
[/code]
It worked for me and hopefully it will work for you. Here is the php timthumb that I used.
