get_available_languages filter

Let’s dive into the world of WordPress hooks! Today, we’re talking about the get_available_languages filter. This handy hook lets you filter the list of available language codes. If you’re tweaking your WordPress site and want to customize language options, this is your go-to filter. To get started, you need to register it using add_filter. You can do this in your theme’s functions.php file or, even better, in a custom WordPress Plugin. This way, nothing breaks when you update your theme in the future. Remember, sometimes you might need to remove a registered hook, and remove_filter is your friend for that!

Example 1: Basic Usage of get_available_languages

Here’s how you can use the get_available_languages filter in a simple manner.

    function weplugins_modify_get_available_languages_defaults($languages, $dir) { 
        // Update the $languages variable according to your website requirements and return this variable.
        return $languages; 
    }
    // add the filter
    add_filter("get_available_languages", "weplugins_modify_get_available_languages_defaults", 10, 2);

Example 3: Conditional Language Modification

Modify the language list conditionally based on your specific requirements.

    function weplugins_conditional_language_modification($languages, $dir) {
        if (some_condition()) {
            // Modify the $languages array
        }
        return $languages;
    }
    add_filter("get_available_languages", "weplugins_conditional_language_modification", 10, 2);
