Change Upload Directory in Multisite

Ouch… Just noticed that for the default directory all image requests are routed through a php file that loads the full WordPress engine and checks the database and stuff… Another reason to change the way uploaded images are handled in WPMU…

Doesn’t seem to be possible easily though. Have found blogs.dir hardcoded in too many places in the source.

I found another solution by adding a sunrise.php to my installation:

add_filter('upload_dir', 'fix_my_upload_dir');

function fix_my_upload_dir($uploads) {
    $blogdir = [...] find a subdirectory you want to use [...];

    $uploads['basedir'] = '/var/www/somedirectory/' . $blogdir;
    $uploads['baseurl'] = 'http://content.bloxxx.net/' . $blogdir;

    $uploads['path'] = $uploads['basedir'] . $uploads['subdir'];
    $uploads['url'] = $uploads['baseurl'] . $uploads['subdir'];

    return $uploads;
}
