WP_Theme::load_textdomain() WordPress Method

The load_textdomain() method is used to load a plugin or theme's textdomain. This method is typically called during the plugin's or theme's init() method. Textdomains are used to store translated strings for a plugin or theme. By default, a plugin or theme's textdomain is the same as its slug. For example, the textdomain for the "Hello Dolly" plugin is "hello-dolly". The load_textdomain() method accepts two arguments: the textdomain and the abspath to the plugin or theme's directory. The abspath is used to determine which .mo file to load. For example, the following code would load the "hello-dolly" textdomain: $theme->load_textdomain( 'hello-dolly', '/path/to/hello-dolly/' ); If the textdomain is not specified, the default textdomain will be used. The load_textdomain() method will return true if the textdomain was successfully loaded, or false if it failed.
