wp_upload_dir( string $time = null, bool $create_dir = true, bool $refresh_cache = false )
Returns an array containing the current upload directory’s path and URL.
Contents
Description Description
Checks the ‘upload_path’ option, which should be from the web root folder, and if it isn’t empty it will be used. If it is empty, then the path will be ‘WP_CONTENT_DIR/uploads’. If the ‘UPLOADS’ constant is defined, then it will override the ‘upload_path’ option and ‘WP_CONTENT_DIR/uploads’ path.
The upload URL path is set either by the ‘upload_url_path’ option or by using the ‘WP_CONTENT_URL’ constant and appending ‘/uploads’ to the path.
If the ‘uploads_use_yearmonth_folders’ is set to true (checkbox if checked in the administration settings panel), then the time will be used. The format will be year first and then month.
If the path couldn’t be created, then an error will be returned with the key ‘error’ containing the error message. The error suggests that the parent directory is not writable by the server.
Parameters Parameters

More Information More Information
Note that using this function will create a subfolder in your Uploads folder corresponding to the queried month (or current month, if no $time argument is provided), if that folder is not already there. You don’t have to upload anything in order for this folder to be created.
For creating custom folder for users
$current_user = wp_get_current_user();
$upload_dir = wp_upload_dir();
if ( isset( $current_user->user_login ) && ! empty( $upload_dir['basedir'] ) ) {
$user_dirname = $upload_dir['basedir'].'/'.$current_user->user_login;
if ( ! file_exists( $user_dirname ) ) {
wp_mkdir_p( $user_dirname );
}
}
Folder Name Folder Name
In case you want to move the /uploads folder, you’ll have to use the UPLOADS constant. It normally shouldn’t get used, as it only get’s defined when ms_default_constants() is run (only multisite), but you can simply set:
define( 'UPLOADS', trailingslashit( WP_CONTENT_DIR ) . 'custom_uploads_name' );
in a single site install and it will just work, as the public directory structure function wp_upload_dir() sets it up, when it was defined:
$dir = ABSPATH . UPLOADS;
Note: You can extract the folder name with the following line:
// returns `false` if the UPLOADS constant is not defined
$upload_dir_name = false;
if ( defined( 'UPLOADS' ) ) {
str_replace( trailingslashit( WP_CONTENT_DIR ), '', untrailingslashit( UPLOADS ) );
}

Strangely wp_upload_dir doesn’t return https for SSL websites. Hopefully they fix the issue soon. Here is the code below where you can get the upload dir and url in right way:
/** * Get the upload URL/path in right way (works with SSL). * * @param $param string "basedir" or "baseurl" * @return string */ function fn_get_upload_dir_var( $param, $subfolder = '' ) { $upload_dir = wp_upload_dir(); $url = $upload_dir[ $param ]; if ( $param === 'baseurl' && is_ssl() ) { $url = str_replace( 'http://', 'https://', $url ); } return $url . $subfolder; }Expand full source codeCollapse full source code

Feedback
#25449 seems to be the relevant ticket. — By mrwweb —
I needed to NOT rely on Gravatar at all, and just use the buddypress profile avatar. Here is the result.
$avatar_url = bp_core_fetch_avatar(array('item_id'=>$user->ID,'html'=>false)); if (strpos($avatar_url, 'www.gravatar.com/avatar') !== false) { $upload_dir = wp_upload_dir(); $avatar_url = $upload_dir['baseurl'] . '/avatars/pi-gravatar.jpg'; }Note that the ‘upload_path’ option that is mentioned has been removed since WP3.5, so this check is only still there for backwards compatibility.
Basic example to produce the upload directory URL.
If you want to create a directory in wp-contents/uploads folder at the time of WordPress PlugIn activation, here is the code:
function yourprojectname_activate() { $upload = wp_upload_dir(); $upload_dir = $upload['basedir']; $upload_dir = $upload_dir . '/your-project-name'; if (! is_dir($upload_dir)) { mkdir( $upload_dir, 0700 ); } }In case this helps anyone, on a multisite instance, the site and site number are appended to the end of the paths.
It’s important to note that the [‘subdir’] key still returns the year/month structure, but all other related paths add the above directories in a Multisite environment.
