Woocommerce – Uncaught Error: Call to undefined function wc() and WC()

I just created a file called custom_functions.php inside of my current active child theme, and when I try to add a product to the cart with this simple line of code, I get an error:

Code:

<?php
    WC()->cart->add_to_cart( 204 );
    //wc()->cart->add_to_cart( 204 );
?>

Error:

 Fatal error: Uncaught Error: Call to undefined function WC() in /homepages/11/d870651981/htdocs/clickandbuilds/XXXXXXX/wp-content/themes/motors-child/custom_functions.php:2 Stack trace: #0 {main} thrown in /homepages/11/d870651981/htdocs/clickandbuilds/XXXXXXX/wp-content/themes/motors-child/custom_functions.php on line 2

I have been reading on Internet that you don’t need to import anything else, just use WC().

I’m executing that code from functions.php file using jQuery AJAX.

What am I doing wrong?

    1.In your functions.php file, add the following line of code to include the custom_functions.php file:

    // functions.php (child theme)
include_once( get_stylesheet_directory() . '/custom_functions.php' );

    2.In your custom_functions.php file, you can use the ‘woocommerce_loaded’ action hook to ensure that WooCommerce is loaded before your code runs:

    // custom_functions.php (inside your child theme)
add_action( 'woocommerce_loaded', 'custom_add_to_cart' );
function custom_add_to_cart() {
    WC()->cart->add_to_cart( 204 );
}
