How to use gettext_domain filter in WordPress

Working with WordPress hooks can be a game-changer, especially when you’re keen on customizing your site without altering core files. One such handy filter hook is the gettext_domain filter. It’s an essential tool if you want to translate strings dynamically based on your site’s text domain. Let’s dive into how to use it effectively with some real-world examples!

Example 1: Basic Translation Override

In this example, we’ll see how to modify the default translations on your WordPress site. This can be particularly useful if you need to tweak translations provided by plugins or themes.

    function weplugins_modify_gettext_domain_defaults($translation, $text, $domain) { 
        // Update the $translation variable according to your website requirements and return this variable.
        return $translation; 
    }
    // add the filter
    add_filter( "gettext_domain", "weplugins_modify_gettext_domain_defaults", 10, 3 );
    

Example 2: Conditional Translation

Sometimes, you might want to change translations based on specific conditions. Here’s how you can achieve that using the gettext_domain filter.

    function weplugins_conditional_gettext_domain($translation, $text, $domain) { 
        if ($domain === 'my_plugin_domain' && $text === 'Hello World') {
            $translation = 'Namaste Duniya';
        }
        return $translation; 
    }
    add_filter( "gettext_domain", "weplugins_conditional_gettext_domain", 10, 3 );
    

Example 3: Removing a Translation Hook

If you need to remove a previously registered translation modification, you can use remove_filter. This is how you do it:

    remove_filter( "gettext_domain", "weplugins_modify_gettext_domain_defaults", 10, 3 );
    

Remember to use the exact callback function name, priority, and number of arguments when removing a hook.
