Widget to Translate Blog Link Categories with WPML
Posted on Thursday, December 3rd, 2009 by Dan Imbrogno
I’ve been using the WPML plugin on a few sites recently to turn Wordpress into a very powerful multilingual CMS, with great success. I really have to applaud these guys for building a very useful plugin. On the to-do list is integrating their plug-in with Wordpress’ built-in widgets. A few people have mentioned getting stuck when trying to use the Links feature of Wordpress, which does not currently work with WPML.
To fix this issue, I’ve thrown together a quick widget that acts as a wrapper for Wordpress’ built-in widget, but lets you set a different link category for each language you have setup using WPML. I hope you find this useful.
To install, copy and paste this into your theme’s function.php file or insert code into a file in the plugins directory.
