How to Translate a WordPress Plugin/Theme

If you haven’t translated a WordPress plugin/theme before, it’s easier than you might think and doesn’t take all that long. Developers don’t always create translation ready themes, so when you buy a premium theme make sure to check the plugin’s features list or ask the developer if the plugin has been localized.

There are three types of files used in the framework:

  • POT (Portable Object Template) files: The first step in the translation process is using a program to search through the WordPress source code to pick out text passed into a __() or __e() function, generating a POT file. This file will contain all the text available for translation.
  • PO (Portable Object) files: The second step involves translating the text in a POT file into the target language, saving both English and translator messages in a PO file.
  • MO (Machine Object) files: In the last step, the PO file is converted into a machine readable format.

There are many translation tools available, such as GlotPress, Launchpad and Pootle, but we’re going to use LOCO Translate. LOCO Translate is a free, easy to use open source program for Mac OS X, Windows and UNIX/Linux for editing PO files and generating MO files. In this post I’ll show you how to translate a plugin/theme using LOCO Translate.
