Changeset 29630 for trunk/src/wp-admin/includes/upgrade.php

Timestamp:

08/26/2014 07:58:33 PM (10 years ago)

Author:

Message:

Language packs: No WPLANG anymore.

• The WPLANG constant is no longer needed. Remove define('WPLANG', ); from wp-config-sample.php. Populate WPLANG option based on the WPLANG constant. When get_option('WPLANG') is an empty string it will override WPLANG.
• Introduce translations_api() which is available to communicate with the translation API. Move translation install related functions to a new file.
• Replace mu_dropdown_languages() with wp_dropdown_languages(). wp_dropdown_languages() is now populated by the translation API.
• Remove wp_install_load_language() and allow load_default_textdomain() to switch a core translation.

fixes #13069, #15677, #19760, #28730, #29281.
