A language prefix in the URL adds a language folder to store links (e.g., /en/, /ua/ ) and automatically selects the language based on the first segment of the URL. As a result, each language version has its own clear address, and language switching and link generation work without broken routes or unnecessary 404s.

Compatible with ocStore 3.x only

Key Features

Determines the language by folder in the URL on all pages: home ( /en, /en/ ), catalog pages ( /en/product ) and links with parameters (UTM).
Fixes _route_ when SEO URL is enabled: removes the language folder from the route so that OpenCart can find the page correctly.
Automatically creates 301 redirects:
- to the URL with the language folder, if there should be one (folder mode for the default language is enabled);
- to a URL without a folder for the default language if the folder is disabled ( langdir_off ).
Adds the language folder to the links that OpenCart generates via url->link(), including the homepage (taking into account the SEO Pro slash option).
Processes search: if a search request is received without a language folder, the module will redirect to the correct URL with the required language.
Outputs hreflang tags to <head> (via extension/module/langdir controller) so that search engines understand the language versions of pages.
Substitutes different meta title/description/keywords for the main page by language (from the langdir_data settings).
Supports different addresses on the contact page by language (taken from langdir_data, otherwise - the standard config_address ).

Benefits for the store

Clear language URLs eliminate confusion: both the user and the bot immediately see the correct version of the site.
Fewer duplicates and 404s routes and redirects bring links to a uniform format.
Better international SEO hreflang + separate metadata for the homepage by language.
Correct links are everywhere even index.php?route=... are formed with the required language folder.

Application examples

You have 3 languages: /ua/, /en/, /pl/ - the module automatically switches the language by URL and brings the routes to the correct format.
The default language folder is not needed: when visiting /en/ (if en is the default language), the visitor will get a 301 for the URL without the folder.
Advertising links with UTM to the "language homepage" ( /en?utm_source=... ) correctly determine the language and do not break navigation.
