PrestaShop comes multilingual out of the box: there are 5 is one default languages (English, French, Spanish, Deutsch and Italianlanguage (the one you used to install it), and many more are available to download.
Adding a new language is simply a question of importing the localization pack from a country which uses that language (in the "Localization" page). If it turns out this does not work, or that you need something customized, you can add a new language manually, using the form behind the "Add new" button.
Creating a New Language
Creating a new language means you will have to translate all of the text for PrestaShop's front-end, back-end, modules, etc., or risk using the default English strings. Translation is made using the tool in the "Translations" page, under the "Localization" menu.
You can also create a new language in order to cater for a language pack that you would have downloaded from the PrestaShop site.
In order to create a new language, you must fill as many of the form's field as possible:
- Name. The name is public. If you are creating that language for regional purpose, you may indicate that in the name: "French (Quebec)", for instance.
- ISO code. Enter the adequate 2-letter ISO 639-1 code. See http://en.wikipedia.org/wiki/List_of_ISO_639-1_codes for more information.
If you are importing a language pack, this code should exactly match the one for the pack.
- Language code. Enter the adequate 4-letter languages language code, in the form
xxbeing the language ISO code (same as above), and
yythe country ISO code, using ISO 3166-1 alpha-2 (http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2). See http://en.wikipedia.org/wiki/IETF_language_tag for more information.
- Date format. Countries do not always share the same date representation (See http://en.wikipedia.org/wiki/Date_format_by_country). Hence, when your shop display 02/08/12, a customer from France will understand "August 2nd, 2012" whereas one from the US will understand "February 8th, 2012" – and a japan customer might even read it as "August 12th, 2002". This is why it is important to indicate the date format tied to your language. The letters used should be that of PHP's
- Date format (full). Same as the date format above, but including the hour-minute format.
- Flag. Upload an image of the flag which best matches the language you want to add. It should be 16*11 pixels. You recommend you use the free FamFamFam Flags image set: http://www.famfamfam.com/lab/icons/flags/.
- No-picture" image. Upload an image which will be displayed when a product does not yet have a picture. That image is simply a blank image, with "No image" or "No image available" in this language. The picture should be 250*250 pixels. You can find existing "No-picture" images in the
/img/ldirectory of your PrestaShop installation.
- Is RTL language. Some languages are written from right to left, most notably those using Arabic script or the Hebrew alphabet (http://en.wikipedia.org/wiki/Right-to-left). When a PrestaShop theme is well coded, it is able to handle RTL languages - provided it is clearly set as such.
- Status. You may disable a new language until you are ready to translate everything.
- Shop association. You can make the language only available to a selection of your shops, for instance shops that target a specific locale.
