Translating wordpress plugin

You get the current language of the install with the function get_locale(). WordPress save the language in theoptions table, option_name is WPLANG. But inside the Multisite install is in the table sitemeta.

But is not important. You should use the default functions to load a language file inside the theme template or the plugin.

  • Theme: load_theme_textdomain()
  • Plugin: load_plugin_textdomain()

You find a small example inside this contact form template, public.
