Multisite Language Switcher Comments by


Installation instructions have changed in this version!

This is extension for Multisite Language Switcher plugin

All comments posted on translation-joined pages are displayed on all translation-joined posts. See installation instructions if you want to store all comments into one blog. Advantages: all comments have reply links.


You need to edit the comments.php in your theme folder if you want to store all the comments into one (primary) blog:
* activate the plugin first,
* find “comment_form” function call,
* add “MslsComments::switchBlog();” just in front of it,
* add “MslsComments::restoreBlog();” just below it,
* change the “comment_form();” to “comment_form( array(), MslsComments::postId() );”,
* calls don’t have to be removed if you switch off primary blog functionality.


To do:
* comments counters on multiple post web pages do not work correctly (total = current on page + 1 if post is valid)
* notifications are always send in the primary blog’s language, when storing all comments in one blog

* comment_id counter in a blog should not be higher than 100,000,000
