Tips for developers

The Transifex Live plugin uses WordPress hooks to manipulate the links found in your website’s content, so they always point to the appropriate language. If you use custom post types (or one of your plugins does) that emits the ‘the_content’ filter, our code might not be triggered.

For those cases, it is recommended to manually trigger our custom filter ‘tx_link’ before you return your content, as seen in the example below:

Ex. $updated_content = apply_filters(‘tx_link’, $original_content);

It is also recommended to use widgets in your theme instead of custom code, since this allows you to make your integration more future proof against incompatibilities with 3rd party modules.

Automatic installation is the easiest option as WordPress handles the file transfers itself and you don’t need to leave your web browser. To do an automatic install of Transifex Live, log in to your WordPress admin panel, navigate to the Plugins menu and click Add New.

In the search field type “Transifex Live” and click Search Plugins. Once you’ve found the plugin you can view details about it such as the point release, rating and description. Most importantly of course, you can install it by simply clicking Install Now. After clicking that link you will be asked if you’re sure you want to install the plugin. Click yes and WordPress will automatically complete the installation.
After installation a new menu setting option will appear called ‘Transifex Live’. You will need to complete the admin form before the plugin will become active.


The manual installation method involves downloading the plugin and uploading it to your webserver via your favorite FTP application.

  1. Download the plugin file to your computer and unzip it
  2. Using an FTP program, or your hosting control panel, upload the unzipped plugin folder to your WordPress installation’s wp-content/plugins/ directory.
  3. Activate the plugin from the Plugins menu within the WordPress admin.
    After installation a new menu setting option will appear called ‘Transifex Live’. You will need to complete the admin form before the plugin will become active.


Automatic updates should work like a charm; as always though, ensure you backup your site just in case.

Transifex have done an outstanding job reimagining how we translate content for the web with their Transifex Live service. I am proud to have contributed to the code early on and to see it continue to grow. It not only saves hours of time when compared to other translation methods, but also integrates with one of the most powerful and intuitive localization platforms I have ever seen.
