Why can't check condition in functions.php file in wordpress?

Question

PHP

Hello! I want to connect scripts for Yandex maps to work on certain wordpress pages using the functions.php configuration file. I write a condition like this:

if(is_home() || is_page(1825)) {
function yandex_api(){
    wp_enqueue_script( 'yandexmap', get_stylesheet_directory_uri() . '/js/ya-map.js');
    wp_enqueue_script( 'yandexapi', get_stylesheet_directory_uri() . '/js/yandex-maps.js');
}
add_action( 'wp_enqueue_scripts', 'yandex_api' );
}

but the map does not appear on the pages and the connection of scripts in the code is not displayed. if you remove the conditions - everything works .. What's wrong?

Answer 1

Rewrite the function, the check should be done right inside it:

function yandex_api() {
    if ( is_home() || is_page( 1825 ) ) {
        wp_enqueue_script( 'yandexmap', get_stylesheet_directory_uri() . '/js/ya-map.js' );
        wp_enqueue_script( 'yandexapi', get_stylesheet_directory_uri() . '/js/yandex-maps.js' );
    }
}
add_action( 'wp_enqueue_scripts', 'yandex_api' );

While processing the functions.php file, it is not yet known what page it is.
Therefore, there is no point in doing such checks.
