How to use plugin_locale filter in WordPress

Example 1: Modifying Plugin Locale

Here’s how you can use the plugin_locale filter to modify the plugin’s locale.

    function weplugins_modify_plugin_locale_defaults($locale, $domain) { 
        // Update the $locale variable as per your requirements.
        return $locale; 
    }
    // add the filter
    add_filter( "plugin_locale", "weplugins_modify_plugin_locale_defaults", 10, 2 );
    

Example 2: Conditional Locale Change

Sometimes, you might want to change the locale conditionally. Here’s how you can do it.

    function weplugins_conditional_locale_change($locale, $domain) { 
        if ($domain == 'my_text_domain') {
            $locale = 'fr_FR'; // Change locale for a specific domain
        }
        return $locale;
    }
    add_filter( "plugin_locale", "weplugins_conditional_locale_change", 10, 2 );
    

Example 3: Removing the Filter

If you need to remove a filter, use the code below. Remember to match the callback function name, priority, and number of arguments.

    remove_filter( "plugin_locale", "weplugins_modify_plugin_locale_defaults", 10, 2 );
