wpgmp_map_lang

The wpgmp_map_lang hook in the WP Maps Pro plugin allows developers to customize the language setting of the map dynamically. It is particularly useful when you need to display the map in different languages based on user preferences or settings.

Usage

Developers can implement this hook in their theme’s functions.php file or within a custom plugin. By attaching a function to this hook, you can modify the language parameter of the map at runtime. It’s important to ensure the language code you set is supported by the map service you are utilizing.

Example 1

This example demonstrates how to change the map language to Spanish.

add_filter('wpgmp_map_lang', 'set_map_language_to_spanish');
function set_map_language_to_spanish($language) {
    return 'es';
}

Example 2

In this example, the map language is set based on a user’s profile setting.

add_filter('wpgmp_map_lang', 'customize_map_language_based_on_user');
function customize_map_language_based_on_user($language) {
    $user_language = get_user_meta(get_current_user_id(), 'preferred_language', true);
    return $user_language ? $user_language : 'en';
}

Example 3

Here, the map language is selected according to the site’s default language set in the settings.

add_filter('wpgmp_map_lang', 'set_map_language_to_site_default');
function set_map_language_to_site_default($language) {
    $site_language = get_option('WPLANG');
    return $site_language ? $site_language : 'en';
}

Tip: When using the wpgmp_map_lang hook, always validate the language code to ensure compatibility with the map service. Additionally, consider user experience and provide fallbacks when necessary.
