Table of Contents

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

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”

The Linguise API key will need to be copied in the Configuration.php file you’ve uploaded on your server, edit the file and copy your API Key between the simple quotes, replace the text REPLACE_BY_TOUR TOKEN.

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.

open-cart-files

From the OpenCart system settings, check that the URL rewriting is activated. Use the OpenCart admin menu: System > Settings > Default > Server

opencart-settings

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/

opencart-frontend

The language switcher is the flag popup to select the language you want. To load it, you’ll need to copy the code given at the end of the website configuration to the head of your HTML page. The flag language switcher will then be loaded automatically.

The language switcher will be displayed by default in a floating top right position on your website. You are welcome to customize it as you wish with CSS.

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
