Loads plugin and theme text domains just-in-time.

Description

When a textdomain is encountered for the first time, we try to load the translation file from wp-content/languages, removing the need to call load_plugin_textdomain() or load_theme_textdomain() .

Parameters

$domainstringrequired

Text domain. Unique identifier for retrieving translated strings.

Return

Source

		$mofile = "{$path}{$locale}.mo";
	} else {
		$mofile = "{$path}{$domain}-{$locale}.mo";
	}

	return load_textdomain( $domain, $mofile, $locale );
