After changing FTP_BASE
in my wp-config
i found the update function of WP broken. Then i realize the update function work the same way and don’t need any additional settings.
In wp-admin/includes/update-core.php
i found the usage of $wp_filesystem->wp_content_dir()
. This solves my problem too.
On http://xref.wordpress.org/branches/3.8/WordPress/Filesystem/WP_Filesystem_Base.html you will find a list of possible useful functions:
string wp_content_dir ()
string wp_lang_dir ()
string wp_plugins_dir ()
string wp_themes_dir ([string $theme = false])
In fact @otto give my the answer earlier (Using wp_filesystem in Plugins), here he wrote:
When using the $wp_filesystem, there’s a handy function call for
getting the content directory path: $wp_filesystem->wp_content_dir();.
You need to use this function because the “remote” directory path may
not be the same as the “local” directory path.
