Technical OpenCart requirements
The neural automatic translation to be used with OpenCart will require to use the PHP script (can be downloaded below). In order to install the Linguise script, you’ll need the following requirements:
- Run PHP 7+
- Apache, LiteSpeed, NGINX, IIS server
- Activate the URL rewriting though the PrestaShop configuration
How to install OpenCart translation
1. Generate the API Key to activate translation
After your connection to your Linguise dashboard you’ll need to setup a new domain first and save it’s settings to get the API Key.
The API key is what is required to activate the translation on your OpenCart website. Basically, the API key will check what language is activated on what domain and will allow the neural translation pages to be generated.
Copy the API Key and keep it in your clipboard.
Then by clicking on the tab “Script PHP” you’ll get the installation instructions we’ll follow here in details.
2. Upload and connect the Linguise script with OpenCart
The Linguise translation script needs to be uploaded on your server where OpenCart is installed:
After the script is downloaded, unzip it and upload it to the root folder where the CMS is installed.
- Make sure it’s at the root level of your website (where your OpenCart files are located)
- Make sure the folder keep its default name “linguise”
How to access Linguise Script Interface?
After completing the Linguise installation, you can access the dashboard by visiting your website with the following URL format:
https://www.domain.com/linguise
Change the domain address according to your website address*
Ensure Linguise have proper read and write permission*
Setup Password and Database Connection
Once you access the script interface, you’ll be presented with a setup screen where you can create a password and connect to your preferred database.
You can:
- Set a password, which will be required for future access to this interface.
- Choose your database type — either MySQL or SQLite, depending on your setup and preference.
This initial setup ensures secure access and allows you to configure the script according to your environment.
MySQL database connection
If you choose MySQL, a different interface will appear asking for the following connection details of MySQL Configuration Fields below:
Make sure the information is correct to establish a successful connection to your MySQL database.
MySQL vs SQLite – What’s the Difference?
Both MySQL and SQLite are popular database systems used to store and manage data for websites and applications. However, they are designed for different use cases and have some key differences:
| Feature | SQLite | MySQL |
|---|---|---|
| Setup | Very easy (SQLite installation required) | Requires server setup |
| Storage | Single file | Managed by MySQL server |
| Performance | Great for small-scale apps | Better for large, high-traffic systems |
| Use case | Local apps, testing, small sites | Web apps, eCommerce, enterprise systems |
Linguise Script Interface: Setup for PHP platform
The Linguise translation dashboard, previously available only for Joomla and WordPress, now extends support to PHP and additional platforms. This update allows users to seamlessly configure language settings—such as display options, flag styles, and appearance customization—directly from a unified interface, regardless of their CMS or framework.
Administrators can manage Linguise settings more efficiently, with consistent features like language selection popups, shadow effects, and region-specific flag choices variants. The dashboard retains its user-friendly design while offering broader compatibility for diverse web environments.
3. Setup the language URLs in OpenCart
The URL rewriting is usually activated for SEO purpose on OpenCart. The URL rewriting is using a .htaccess file available at the root of your server.
From the OpenCart system settings, check that the URL rewriting is activated. Use the OpenCart admin menu:
System > Settings > Default > Server
The URL by language need to be configured in the .htaccess. Just copy this code after the code “RewriteBase /” available in the default OpenCart .htaccess.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(af|sq|am|ar|hy|az|eu|be|bn|bs|bg|ca|ceb|ny|zh-cn|zh-tw|co|hr|cs|da|nl|en|eo|et|tl|fi|fr|fy|gl|ka|de|el|gu|ht|ha|haw|iw|hi|hmn|hu|is|ig|id|ga|it|ja|jw|kn|kk|km|ko|ku|ky|lo|la|lv|lt|lb|mk|mg|ms|ml|mt|mi|mr|mn|my|ne|no|ps|fa|pl|pt|pa|ro|ru|sm|gd|sr|st|sn|sd|si|sk|sl|so|es|su|sw|sv|tg|ta|te|th|tr|uk|ur|uz|vi|cy|xh|yi|yo|zu|zz-zz)(?:$|/)(.*)$ linguise/linguise.php?linguise_language=$1&original_url=$2 [L,QSA]
</IfModule>
Make sure the path linguise/linguise.php is the same on your server, /linguise/ is the default name when you unzip the script.
4. Activate the language switcher
You can now load all your translated pages using the URL, for example: www.domain.com/fr/
The language switcher is the flag popup to select the language you want. To load it, you’ll need to copy the link to the Linguise script given in the OpenCart header of all your pages. The flag language switcher will then be loaded automatically. Here’s the script link you can find at:
dashboard.linguise.com > Settings
Then to add it to your OpenCart installation, go to Design > Theme editor and edit the default/header of the template.
The language switcher will be displayed by default in a floating top right position on your website. You are ready to customize it from the Linguise dashboard in the next step.
SEO important note: The number of languages you setup has a large impact on SEO. When you setup your translation languages, if you have a large amount of indexed pages (>500), search engine may take a lot of time to process them. It may impact your SEO in your original language. That’s why we recommend adding at first a maximum of 5 languages, then when it’s indexed, you can add languages in a batch of 3 per month.
Setup the language switcher
The language switcher can be customized from the Linguise dashboard > Settings > Language flags display. Every modification here will be reflected on the website.
On the right side of the screen you have the preview of the language switcher. Here are the elements you can setup:
- 3 layouts: side by side, dropdown or popup
- The language switcher position
- The language switcher content
- Language names in English or native language
- Flags shapes and size
- Colors and box shadow
Load the language switcher in OpenCart content
To display the Language switcher at the specific place, in the CMS content, you should set the position as “In place”.
Once you have set the position in the Linguise dashboard, you can add the shortcode below to include it. Click on the code below to put it in your clipboard.
<div>[linguise]</div>
Once it’s added, on the frontend you’ll have the flag and language names displayed in the HTML area you’ve added the code.
Activate translation local cache system
As an option, you can activate a local cache system that stores URLs and its related multilingual content to serve the pages faster. The local cache will save some data transfer between Linguise server and your website server. The cache is used only when a page has already been translated and has not been updated. The cache kept in priority will be the cache from the most viewed multilingual pages.
As an option, you can define the amount of cache stored in MB. In the following example the cache is activated and the amount of cache to keep is 500MB:
/** Basic configuration **/
public $cache_enabled = true;
public $cache_max_size = 500; // In megabyte
Specific settings for OpenCart CMS
In the Configuration.php file we also have a setting that allows to pass some specific configuration for the CMS. By default, it’s automatic, but the support team may ask you to personalize it to use some special settings.
Here’s the code to add for OpenCart, this is the CMS name in lowercase:
/** Basic configuration **/
/*
* Update the CMS value according to your CMS
* Available CMS are: laravel, prestashop
*/
public static $cms = 'opencart';
From SQLite to MySQL
Still in the Configuration.php there’s a setting to force the usage of MySQL instead of SQLite, in case SQLite is not installed on the server.
In this case, you’ll need to fill the MySQL information in this part of the Configuration.php file:
/** Advanced database configuration **/
/*
* In case you don't want to use Sqlite, you can use MySQL
* To do so, you need to fill the following variables
* Linguise will create the tables for you
*/
public static $db_host = '';
public static $db_user = '';
public static $db_password = '';
public static $db_name = '';
public static $db_prefix = '';
Automatic translation on Windows IIS servers
Add the line corresponding to your website builder in your Web.config file.
It should be set before any other redirection, especially the redirection to your PHP main file:
<rule name="Linguise" stopProcessing="true">
<match url="^(af|sq|am|ar|hy|az|eu|be|bn|bs|bg|ca|ceb|ny|zh-cn|zh-tw|co|hr|cs|da|nl|en|eo|et|tl|fi|fr|fy|gl|ka|de|el|gu|ht|ha|haw|iw|hi|hmn|hu|is|ig|id|ga|it|ja|jw|kn|kk|km|ko|ku|ky|lo|la|lv|lt|lb|mk|mg|ms|ml|mt|mi|mr|mn|my|ne|no|ps|fa|pl|pt|pa|ro|ru|sm|gd|sr|st|sn|sd|si|sk|sl|so|es|su|sw|sv|tg|ta|te|th|tr|uk|ur|uz|vi|cy|xh|yi|yo|zu|zz-zz)(?:$|/)(.*)$" ignoreCase="false" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
<action type="Rewrite" url="linguise/linguise.php?linguise_language={R:1}&original_url={R:2}" appendQueryString="true" />
</rule>
