Preparing Plugins for Translation

Before diving into translations, you need to prepare your plugin’s codebase to support multiple languages.

Use Internationalization (i18n) Functions

WordPress offers built-in functions to make text strings translatable:

• __(): Returns a translated string.
• _e(): Echoes a translated string.
• _x(): Provides context for translations.
• esc_html__() and esc_html_e(): Ensure safe HTML output for translated strings.

Example:

_e('Hello, world!', 'plugin-text-domain');  

Define a Text Domain

The text domain identifies your plugin’s translations. Add it to your plugin header:

/*
Plugin Name: My Multilingual Plugin  
Text Domain: my-plugin  
*/  

Create a .pot File

The Portable Object Template (POT) file is the backbone of your plugin’s translation process. It contains all translatable strings. Use tools like Poedit or the xgettext command-line utility to generate a .pot file.

For detailed instructions, refer to the WordPress Internationalization Guide.
