Google Translate API events

This section contains a list of events that trigger translation on the website. Here are available options:

Events in Google Translation

  • Update entity via website

If enabled, the text in the target language will be automatically updated when you are changing something in the text in the source language.

Say you have created a text in Japanese (source language) and translated it into English (target language) with the Cloud Translate service. You have also made some stylistic changes in the English language text. Later, you would like to make some changes in the Japanese text. If the setting is enabled, the English text will be translated again when you change the one in Japanese. It is not recommended to set the setting to active.

  • Create entity via website

If enabled, the new fields filled in the source language will be automatically translated into the target language.

For example, there is no short description in a product. You are creating one in English and it is automatically created in the Japanese version of the product.

  • Create products via import

CS-Cart supports CSV import of products. You can also use the XML import add-on to create new products.

If the setting is enabled, the description in the second language will be automatically created when you are making an import.

To get more details on how the import works, please refer to the CS-Cart documentation. We also have a couple of videos explaining how the XML import add-on works.

  • Update products via import

It means that if you are updating a product automatically the translation can be changed as well.

Fields to translate

Select fields of the entities that you want to translate on your site:

Which fields translate

If you want to translate the entire site, you can do so by setting the CRON in the CRON settings tab.

Cloud translation via CRON

The Translate what is already translated setting allows to translate entities regardless of earlier translations.

Translating individual entities

You can also translate selective entities, like products, categories, pages by clicking the gear button of the corresponding entity.

Here’s an example of translating the Contact us form.
