WordPress MU

I can't seem to add new filetypes to be uploadable. I've added "m4a" and "mp4" to the Upload File Types field under Site Admin > Options but no luck.

When I try to upload a m4a file, I get the generic error message:

File type does not meet security guidelines. Try another.
Back to Image Uploading

Any help would be greatly appreciated...

I believe you also have to add it into the wp-content/blogs.php file.

Hmmm... we've had trouble with m4a files too.

Thanks drmike for pointing me in the right direction, got it figured out.

FIX:
Edit ../wp-includes/functions.php (around line 1210), change:

'exe' => 'application/x-msdownload'
  ));

To:

'exe' => 'application/x-msdownload',
    'm4a' => 'audio/aac',
    'flv' => 'video/x-flv'
  ));

Notice the comma added after 'x-msdownload'. I started by editing wp-content/blogs.php but that didn't work. I didn't remove the added mime types from blogs.php, so I'm not sure if it's a combination of the two that got it to work, just happy it's working now...

Thanks!

Not a problem. Glad you got it worked out.

Farms, does that look right to you?

Yep, it also works for other files, i.e.

'notebook' => 'text/notebook',
'isf' => 'text/isf'

no need to edit blogs.php.

You should be able to use the upload_mimes filter to add new mime types there. Much better than changing a core file.

Isn't that what the poster is trying to do in teh first post by adding in the extentions?

Heck, the last thing I like doing is changing core... for obvious reasons... but surely this is 'cos mimes doesn't support that file type beings added?

Is the upload_mimes filter the same thing as on the Site Admin > Options tab, or is this something else?

I'd love to not have to touch core files...

Guys,

I have the same issue as Hawariian and I too do not want to modify any of the WP files.

Can someone please explain what Donncha means by "... use the upload_mines filter"?
