WordPress MU

Like the title says, I can change the "Upload Path" option of the individual blogs

(as found in blogs > edit blog > Blog options > Upload Path)

and it appears to save the setting, and then totally ignore it. Images are still uploaded to the default path. No error messages.

Yeah, I ran into the same problem when I was trying to get change the location of where files were stored. From what I could tell, Upload Path, Upload Url Path, and Fileupload Url had no effect on any of it.

My motivation for changing the location was because on the server I use, the subfolder blogs.dir/blogid/files/ would be owned solely by Apache, rendering it impossible for users to upload files. What I did to fix this was first modify wp-settings.php, then wp-includes/wpmu-functions.php, and I also added a new rewrite rule in .htaccess (but I don't think this is necessary if you keep the short url of domain.com/blog/files/... ~ blog.domain.com/files/...). While I was at it, I also changed the use of the blogid for user folders, and changed it to the name of their url path (i.e. /blogs.dir/namepath/), which makes it easier for me as admin to easily identify what folder belongs to who.

If you only wanted to change the upload path for a single blog, then the quickest way would be to just add an if statement checking the blog's id and changing the upload location accordingly. A better solution would be to change the code and make it query the database, requesting the upload path for that blog, and if none exists, to use a predefined location. (unless someone has a more viable solution?)

Pearson, I am trying to figure this out too.

I want /blogs.dir/blogid/files (sub.domain.com/files) to reflect a custom directory for each blog. For example,

/blogs.dir/blogid/resources (sub.domain.com/resources)
/blogs.dir/blogid/files (sub.domain.com/files)

Is this possible?
