wp_upload_dir comment obtenir uniquement le nom du répertoire.

Voici ce que vous obtenez de lafonction:

 Array
(
    [path] => C:\development\xampp\htdocs\example.com/content/uploads/2012/04
    [url] => http://example.com/content/uploads/2012/04
    [subdir] => /2012/04
    [basedir] => C:\~\example.com/content/uploads
    [baseurl] => http://example.com/content/uploads
    [error] => 
)
 

Vouspouvez donc obtenir le (comme @OneTrickPony l'a souligné),lenom du dossier/répertoire avec

 echo wp_basename( $uploads['baseurl'] );
 

Si vous utilisez lemultisiteet que vous avez défini la constante UPLOADS,vous y accédez depuis UPLOADS ou BLOGUPLOADDIR.

< EDIT

Pour lesmultisites,vous obtiendrez quelque chose comme ceci:

 Array
(
    [path] => /var/www/example.com/public_html/wp-content/uploads/sites/2/2016/12,
    [url] => http://example.com/wp-content/uploads/sites/2/2016/12,
    [subdir] => /2016/12,
    [basedir] => /var/www/example.com/public_html/wp-content/uploads/sites/2,
    [baseurl] => http://example.com/wp-content/uploads/sites/2,
    [error] => ,
)
 

Où le "2" après sitesest l'ID dublog

This is what you get back from the function:

Array
(
    [path] => C:\development\xampp\htdocs\example.com/content/uploads/2012/04
    [url] => http://example.com/content/uploads/2012/04
    [subdir] => /2012/04
    [basedir] => C:\~\example.com/content/uploads
    [baseurl] => http://example.com/content/uploads
    [error] => 
)

So you can get the (as @OneTrickPony pointed out), folder/directory name with

echo wp_basename( $uploads['baseurl'] );

If you're running multisite and you defined the constant UPLOADS, then you access it from UPLOADS or BLOGUPLOADDIR.

EDIT

For multisites, you would get something like this:

Array
(
    [path] => /var/www/example.com/public_html/wp-content/uploads/sites/2/2016/12,
    [url] => http://example.com/wp-content/uploads/sites/2/2016/12,
    [subdir] => /2016/12,
    [basedir] => /var/www/example.com/public_html/wp-content/uploads/sites/2,
    [baseurl] => http://example.com/wp-content/uploads/sites/2,
    [error] => ,
)

Where the "2" after sites is the blog's ID
