How to Translate WordPress Plugins


WordPress is a global platform used by millions of people worldwide, and being able to translate your WordPress plugins can greatly enhance the accessibility and usability of your website. Fortunately, WordPress provides powerful translation features that allow you to translate plugins into different languages. In this article, we will explore how to translate WordPress plugins effectively.

Prepare Your Plugin for Translation

Before you can start translating a WordPress plugin, you need to ensure that it is ready for translation. This involves using internationalization functions to mark translatable strings within your plugin’s code. WordPress provides the __() and _e() functions for translating strings, as well as the __n() function for handling plural forms.

In your plugin code, replace any hard-coded strings with the appropriate translation functions. For example:

// Original string
echo ‘Hello, World!’;

// Translated string
echo __( ‘Hello, World!’, ‘your-plugin-textdomain’ );

Make sure to assign a unique text domain to your plugin, which acts as an identifier for translation files. Replace 'your-plugin-textdomain' with the text domain of your plugin.


Generate a Translation Template

Next, you need to generate a translation template file (.pot) for your plugin. This file contains all the translatable strings from your plugin and serves as a starting point for translators to create language-specific translation files.

To generate a translation template, you can use tools like the makepot.php script provided by WordPress. Alternatively, you can use translation plugins like “Loco Translate” or “Poedit” to extract the translatable strings and generate the template file.

Translate Strings

Once you have the translation template file, you can start translating the strings into different languages. There are several approaches you can take:

a. Using a Translation Plugin: Install and activate a translation plugin like “Loco Translate” or “WPML.” These plugins provide a user-friendly interface within the WordPress dashboard, allowing you to translate strings directly from there.

b. Using Poedit: Poedit is a popular translation tool that allows you to translate strings outside of WordPress. Open the translation template file (your-plugin-textdomain.pot) in Poedit and provide the translations for each string.

c. Online Translation Services: If you prefer working with professional translators, you can use online translation services like “Crowdin” or “Transifex.” These platforms allow you to collaborate with translators to translate your plugin strings.

Regardless of the approach you choose, make sure to create a separate translation file for each language you want to support. The translation files should have the format your-plugin-textdomain-LANGUAGE_CODE.po (e.g., your-plugin-textdomain-fr_FR.po for French).

Compile Translation Files

Translation files are initially saved in a human-readable format called Portable Object (PO). To make them usable by WordPress, you need to compile them into binary format (MO).

If you’re using a translation plugin like “Loco Translate” or “WPML,” the compilation process is handled automatically. If you’re using Poedit or other translation tools, you will need to use the tool’s built-in compilation feature to generate the MO files.

Install and Activate Translation Files

To make your translated strings available to WordPress, you need to install and activate the translation files.

a. If you’re using a translation plugin, the installation and activation of translation files are typically handled within the plugin’s settings or interface.

b. If you’re using PO/MO files generated by Poedit or other translation tools, you need to place the compiled MO files in the correct directory. Create a folder named languages within your plugin’s directory, and copy the compiled MO files into it.

In conclusion, translating WordPress plugins is a valuable practice for making your website accessible to a global audience. By preparing your plugin for translation, generating translation templates, translating strings, and installing the translation files, you can provide a multilingual experience for your users. Embracing translation enhances user engagement and expands the reach of your website to different language communities. Make your website more inclusive and user-friendly by implementing translation for your WordPress plugins.
