Adds language prefixes to URLs
Adds the hreflang attribute

The extension works only with SEO Pro and will not work without SEO URL and SEO Pro mode enabled in the store settings.

SEO Pro is a module for the correct work of URL links in OpenCart. For OpenCart it needs to be installed additionally. You can find SEO Pro OpenCart on the Github web service or other platforms.

Our extension is compatible with OpenCart 2.3.x.x and 3.0.x.x and PHP 5.6 - 8.x

Advantages of the Multilingual SEO Pro extension over its analogues

Full compliance with Google's guidelines for multilingual websites: adds hreflang attributes to all pages, you can choose a localisation for x-default, multilingual pages are accessible by bots without redirects.
Ability to set different logos for different languages.
Free add-on for the language selection popup when you first visit a website

Hreflang on OpenCart

You can see the work of this module on this site, all multilingual links here are generated by SEO Pro with its help.

Example of link to home page:

https://opencart.com/ - home page in your default language
https://opencart.com/fr/ - version of the site in French
https://opencart.com/en/ - version of the site in English

Example of forming links to internal pages, for example a category:

https://opencart.com/modules/ - category page in your default language
https://opencart.com/fr/modules/ - category page in French
https://opencart.com/en/modules/ - category page in English

Features of the module Multilang SEO Pro OpenCart 3.0 & 2.3:

adds language prefixes to url
links to the main language of the site without a prefix
allows you to write the same SEO URL for different languages (add-on)
adds hreflang attributes to indicate alternate versions of pages in different languages
adds your custom URL prefixes for each language
title, description, meta tags for the home page in different languages
different logos for different languages
correct indexing of pages of different language versions
works with any languages

The prefix can contain any string, such as a short country code /en/ or /us/ or /eng/ or a language and region prefix - /en-us/ (the so-called multi-region).
The hreflang code can only be an iso-2 language code or a hyphenated language and region code, such as "en" or "en-us", but never the country code as "us" or "gb".

Module installation instructions:

You must have installed the SEO Pro extension on your site. The Multilang SEO Pro is add-on for the SEO Pro extension. So you need to install and enable the SEO Pro first. You can download it from the link above.
Upload the Multilang SEO Pro in the admin panel in the "Extensions" : "Install".

Check module operation.
Bingo!

FAQ: Multilang SEO Pro

If an extension is not working properly

If an extension or its functions do not work properly:
- check whether the SEO URL and the SEO Pro extension are enabled. To do this, go to the "System" tab > "Settings" > "Edit store" > "Server", here you need to enable the SEO URL. Here you need to select SEO URL Type = SEO PRO (if the SEO URL Type field is not there - you need to install the SEO Pro extension, the link is in the instructions)
- in the root directory of the site, rename the file 'htaccess.txt' to '.htaccess'
- check if the "Multilang SEO Pro" modification is present in the Extensions -> Modification section
- refresh the modification's cache
- refresh the template cache (twig)
- check if the Multilang SEO Pro module status is enabled
- check if the localization codes are specified in the "Hreflang code" field in the module settings.
- check the Design > Theme Editor section. If there is a generic common/header that can be edited, you need to remove it or install the bugfix https://www.opencart.com/index.php?route=marketplace/extension/info&extension_id=36203
- if you have OpenCart 3.0.3.5 - 3.0.3.6 - you need to install the bugfix https://www.opencart.com/index.php?route=marketplace/extension/info&extension_id=40469

When you go to search on the site, the default language is set. How to fix?

Open the file /catalog/view/javascript/common.js
Find the string:
var url = $('base').attr('href') + 'index.php?route=product/search';
You need to replace it with:

var url = (($('#logo a').length) ? $('#logo a').attr('href') : $('#logo').data('href')) + 'index.php?route=product/search';

Save the file.
Clear your browser cache.

How to add a new language to the site?

To add another language to OpenCart, use our instructions on the example of adding the Ukrainian language.

How to allow the same SEO URLs for different languages in Opencart 3.0?

Starting with version 2.1, this option has been added to the module settings, it is enough to enable the "Same SEO URLs" option there.
Download and install add-ons: allow_same_seo_url_lang_oc3.ocmod.zip
Update caches.

Why do you need to make the same SEO URL for different languages?

It is not necessary to do this. It has no effect on SEO promotion. But this is accepted, it is so convenient, it is more understandable, because if you manually change the prefix (language code) in the URL, you will see the same page in a different language, and if you have different SEO URLs, if you change only the prefix in the URL, you will get a 404 error. This is purely aesthetics.

Error 404 when switching languages. How to fix?

You are most likely using an outdated version of SEO Pro where this issue existed. You need to update the SEO Pro module to the latest version. You can download the working version of SEO Pro from our fork on github

If you have an Nginx server - you need to adjust its config, because when the link is not clear SEO URL - the server sees that there is no folder with a prefix name in the root of the site (for example /us/) and gives a 404 error instead of allowing the site's url to be processed by the script. that is, in SEO Pro.
Solution: in the nginx config find the code:


if (!-f $document_root$fastcgi_script_name) {

	return  404;

}

and before it add the following code:


if (!-e $request_filename) {

	rewrite ^/(.+)$ /index.php?_route_=$1 last;

}

The configuration file is usually called nginx.conf and is located in /usr/local/nginx/conf or /usr/local/etc/nginx or /etc/nginx or /etc/httpd/nginx.conf
Or ask the technical support of your server/host to help solve this problem, provide them with this instruction.

The prefix is duplicated on the home page, or home url contain index.php?route=... How to fix?

In the admin panel, open the Design : SEO URL section and filter the entries by the filter "Route" = "common/home".
All such entries in the Keyword field should be empty, as in the screenshot below:

If you have something written there, for example a slash "/" or a language code, you need to edit and clear the Keyword field.
Attention! The system does not allow you to create an empty SEO URL. ~~To solve this problem, you need to install the fix allow_empty_seo_url.ocmod.zip or edit the SEO URL through the database in the "oc_seo_url" table.~~
In order for the system to allow adding empty SEO URLs, the option "Same SEO URLs" must be enabled in the module settings.
If you do not have records for all languages, you need to create an SEO URL record for each language, where query = "common/home" and keyword is empty value (as in the screenshot above).
After any manipulation of the SEO URL, you need to clear the system cache in order to update the cache of the SEO PRO. The SEO PRO cache is automatically reset when you save the settings of the "Multilang SEO Pro" module, so you can simply re-save the module settings.

How to make language switchers as links?

To display language switches as links, add the following code to the common/header.twig template:


<ul class="list-inline">

{% for hreflang in hreflangs %}

  {% if hreflang.code == code %}

    <li><a class="active">{{ hreflang.code[:2]|upper }}</a></li>

  {% else %}

    <li><a href="{{ hreflang.href }}">{{ hreflang.code[:2]|upper }}</a></li>

  {% endif %}

{% endfor %}

</ul>

If you need to change the text on the links, for example, to display the name of the language there, then you need replace {{ hreflang.code[:2]|upper }} to {{ hreflang.name }}

If you need to display links in the form of a drop-down list, transform the code as follows:


<ul class="list-inline">

 <li class="dropdown">

  {% for hreflang in hreflangs %}

    {% if hreflang.code == code %}

     <a class="dropdown-toggle" data-toggle="dropdown">{{ hreflang.name }}<span class="caret"></span></a>

    {% endif %}

  {% endfor %}

 <ul class="dropdown-menu dropdown-menu-right">

 {% for hreflang in hreflangs %}

  {% if hreflang.code == code %}

    <li><a class="active">{{ hreflang.name }}</a></li>

  {% else %}

    <li><a href="{{ hreflang.href }}">{{ hreflang.name }}</a></li>

  {% endif %}

 {% endfor %}

 </ul>

 </li>

</ul>

Don't forget to refresh the modification cache and template cache after editing the template.

Why do you need to make language switches html links?

Some SEO experts advise that the page should have links to its versions in other languages. Therefore, it is advised to make the language switcher not with a js script, as implemented by default, but with html links. This is a technical point.

Is it possible to specify the localized versions of pages (hreflang) in only one way?

Language versions of pages (hreflang) can be passed in only one way (HTML Tags, HTTP Headers, Sitemap) and this should be enough for search engines to link these pages. This, in particular, is stated in the Google documentation https://developers.google.com/search/docs/advanced/crawling/localized-versions
When you send hreflang in several ways at the same time - this is not a mistake, on the contrary, because you transmit more information about the content and this should have a positive effect on promotion. Only in this case, it is necessary to ensure that the data transmitted by several methods are identical.

How to copy SEO URL from one language to another?

You can copy all SEO URL records from one language to another using the following mySQL query, which can be executed in the SQL tab of the phpmyadmin database control panel:


CREATE table `temp_seo_url` AS SELECT * FROM `oc_seo_url` WHERE language_id = "1";

UPDATE `temp_seo_url` SET language_id = "2";

UPDATE `temp_seo_url` SET seo_url_id = 0;

INSERT INTO `oc_seo_url` SELECT * FROM `temp_seo_url`;

DROP TABLE `temp_seo_url`;

Here language_id = "1" is the id of the language from which we will copy, and language_id = "2" - where we will paste. Insert the id of the languages you need here.

Also, before this request, you can perform another request to remove all SEO URLs of the new language that you have already added manually:
DELETE FROM `oc_seo_url` WHERE language_id = "2";

Доброго дня, чи є можливість додати у посилання товара / у кінці. Тобто зробити щоб посилання товару виглядало https://url/product/product-url/

Дякую )

opencartbot	24 March 2025
Добрий день! Для цього потрібно зробити певну модифікацію коду SEO Pro, щоб додався слеш до URL товарів. Ваше питання не стосується роботи розширення для мультимовності. Дякую за зверення!

Hello,
Can I use your extension just to put a language prefix in a URL?
For example:
domain.com/en/category/product1
domain.com/de/category/product1

The website is on OC 3.0.4.0 Journal Theme

Regards

opencartbot

12 February 2025

Hello.
Of course, but you should know that the default language of store will always be without a prefix, and all additional languages will have prefixes.
And the Journal theme also requires an additional extension.

Thanks

Al Petrov

12 February 2025

That's okay for the default language, I need prefix only for the second language.
I want to set only prefix for the second language without reflecting SEO URLs because my URLs (products, categories, etc.) are okay, just need to separate both languages.
I have to buy two extension or the other extension - https://opencartbot.com/en/seo-pro-journal3 ?

opencartbot	12 February 2025
Yes, that's right.

Придбав одразу два модулі для свого проекту Багатомовність для SEO Pro OpenCart і Модуль Багатомовна карта сайту XML OpenCart. Усе встановилося без проблем. Допомогу в налаштуванні надав Розробник за першим моїм зверненням. Як потім виявилося - вся інформація з налаштування була на закладці Ліцензія. Просто треба було уважніше читати. Велике спасибі за хорошу розробку і підтримку!

Якщо є спеціальний модуль для цього або навики, то мабуть не важко. У цьому модулі, як ви зрозуміли, такої функції немає.

Куди звернутись з приводу роботи модуля? В розділі дизайн нічого нема, коли в вкладці сервер обираю Seopro всі урли взагалі робляться не зрозумілі. Кому писати? Поки 3

opencartbot

На сайті є розділи Контакти, Підтримка. Також контакти вказані на кожній сторінці внизу.
В розділі меню Дизайн > SEO URL (це стандартний розділ) додаються SEO URL, щоб ваші сторінки мали ЧПУ URL. SEO Pro треба увімкнути, без нього модуль не працюватиме. Якщо щось не виходить - звертайтесь у підтримку.

Цей модуль призначений в основному для нашого внутрішнього ринку, де користуються розширенням SEO Pro і знають, що це таке. Тому дане доповнення можна придбати лише тут.

Игор Моржецький	09 February 2024
Перевищів всі очікування. Встановлення пройшло чітко за інструкцією, навіть в технічну підтримку звертатися не було необхідності. Автори відповідають навіть за межами робочого часу, що тоже дуже приємно. Мое завдання було вирішено за 15 хвилин (включаючи онлайн оплату :-).
