💼 Career

Knowing how to make themes translation-ready is essential for WordPress theme developers working with international clients or marketplaces.

1

Create the theme text domain variable

Create a variable called $theme_text_domain and set it to the string 'mytheme'.

Wordpress

# Your code here

Need a hint?

The text domain is a unique identifier for your theme's translations. It is usually your theme's folder name.

2

Load the theme text domain

Add code to load the theme text domain using load_theme_textdomain with the variable $theme_text_domain and the path get_template_directory() . '/languages' inside a function called mytheme_setup hooked to after_setup_theme.

Wordpress

<?php
$theme_text_domain = 'mytheme';
// Your code here

Need a hint?

This code tells WordPress where to find your translation files so it can use them.

3

Use translation functions for visible text

In your theme's header.php file, write a line that outputs the site title using echo and the translation function __() with the text 'Welcome to My Theme' and the text domain variable $theme_text_domain.

Wordpress

<?php
$theme_text_domain = 'mytheme';

function mytheme_setup() {
    global $theme_text_domain;
    load_theme_textdomain($theme_text_domain, get_template_directory() . '/languages');
}
add_action('after_setup_theme', 'mytheme_setup');

// header.php content
// Your code here

Need a hint?

The __() function marks text for translation and returns the translated string.

4

Add the languages folder for translation files

Add a comment line that says // Create a folder named 'languages' in your theme directory to store .mo and .po files to remind where translation files go.

Wordpress

<?php
$theme_text_domain = 'mytheme';

function mytheme_setup() {
    global $theme_text_domain;
    load_theme_textdomain($theme_text_domain, get_template_directory() . '/languages');
}
add_action('after_setup_theme', 'mytheme_setup');

// header.php content

echo __('Welcome to My Theme', $theme_text_domain);

// Your code here

Need a hint?

This folder is where translators put the files that contain the translated text.
