WordPress is the fastest growing content management system powering millions of websites across the internet. WordPress core has been translated to many foreign languages by WordPress Core Team while WordPress theme translation remains the role of theme authors.
Allowing WordPress users to manage or create websites in their native languages is very important. As the WordPress community continues to grow globally, there is need for WordPress themes and plugins to be translated in different languages.
Translating WordPress themes and plugins becomes very important especially for themes listed in WordPress repository and premium marketplaces for users who do not speak English as their native language.
Translating themes and plugins allows users to build websites in their native. Translating WordPress theme is also commonly referred as ‘localization’ which simply means translation of the theme content, descriptions, WordPress instructions and customizer to a local language. It is important to note that theme translation does not mean translation of the WordPress pages and posts but the language used in the theme’s files. By default majority of WordPress themes are developed and written in English and most of the translation is done from English to another language.
Translating WordPress Theme
The following are a few steps to take in order to translate a WordPress theme to your desirable language:
Step 1: Check if your Theme is Translation Ready
There are many WordPress themes both free and premium that are ready for translation. If you are looking for a translation ready theme there are several free themes listed in WordPress repository as translation ready.
You can search for translation ready theme on WordPress repository using the Translation Ready tag.
You can identify several themes on WordPress repository that are translation ready then you choose the theme of your choice and download it.
In this tutorial we will be translating Twenty Sixteen WordPress theme to Swahili language.
A translation ready theme contains a language folder with a .POT file. This file is important for translation of your WordPress theme and it can be found inside the languages folder theme/languages/ among the WordPress theme files.
This file extension POT stands for portable object template or sometime abbreviated as .PO which means portable object while MO stands for machine object.
Step 2: Begin Translation Download and Install Poedit
To start your theme translation you need to download and install in your machine poedit which is the ideal gettext translation file editor for WordPress.
You simply go to this website Poedit download and install it this translation aid software in your computer. This software can be downloaded for free by both Mac and Windows users.
To install the software click on the .exe installation file then follow the prompts to install poedit in both Mac and Windows.
When you have successfully installed poedit software in your computer you should now launch the program to begin your theme translation.
If you are successful you should see the following welcome screen of this gettext file editor.
Step 3: Create a Translation from Existing PO theme file
When you look at the welcome screen of poedit software there are three options available, which include edit a translation, create new translation and translate WordPress theme or plugin. In our case we will utilize the second option since the third option is only available for the premium version of this software.
You should now choose the ‘Create a translation’ option and navigate to the location of your .POT file inside your WordPress theme.
In our case we will be translating the WordPress Twenty Sixteen theme to Swahili language. This process involves picking the preferred language, this process is the same for all available languages.
Step 4: Translate and Edit the Translations from the Poedit Screen
You should now begin the process of translation by picking your preferred language from the list of all available languages.
When you pick the language you should now see on the left side the list of WordPress phrases in English with equivalent translation suggestions on the right side. You should now click on each of these translations and edit it on the bottom left side to improve its accuracy. You can save your translation and edit later if you don’t have enough time to edit all the phrases in the file.
Step 5: Save Translation Files and Enable Translation in wp-config
When you have finished editing all the translations files you should now save them as .PO and .MO files and ensure they are saved or uploaded in the languages folder of your theme. It is very crucial to ensure that both files are saved and uploaded to the languages folder for successful theme translation.
You should also ensure these files are named well according to the language code. After saving these files we now ready to enable the translation by editing the wp-config.php file in the WordPress installation to complete the translation. If your site is live you should use the FTP to locate the wp-config.php file and edit it. Ideally on a live site the file will be found inside the public_html/site directory path.
When you locate this file wp-config.php open it and locate the following line of code:
define ('WPLANG', 'en_EN');
In some instances this PHP CONSTANT for defining language may be missing inside the wp-config file. If this line of code is missing, you just need to copy it inside the file, make the changes and save the file.
Now it’s time to change the theme language to our preference. In the case of this tutorial we should substitute it with Swahili language code:
define ('WPLANG', 'sw_KE');
The first part of this code shows the language you translated your theme to while the second part of code shows the country. In this case ‘sw’ is Swahili language code while ‘KE’ is country code of Kenya. The language code should always precede the country code and they should be separated by an underscore. You have now successfully defined the preferred language and now its time to save and close this file then check your website to see if the translation is successful.
This is the result of successfully translating Twenty Sixteen theme to Swahili. You can apply this tutorial to translate any theme in any of your preferred language.
Finally, you should remember that WordPress theme translation is a progressive process that you can keep working on, saving your new edits of the .PO file which will be reflected on your site immediately.
