Determine language in functions.php [wpml] - php

Question

I have function in functions.php , which automatically adds woocommerce product by ID to cart when website is visited.
The website is bilingual and the function can't determine translated product ID.
So, I want to know if is possible to add wpml function in functions.php, which determines first language of front end, then executes function, something like this:
<?php if(wpml_getLanguage()=='en'); ?>
---do function for product 22---
<?php elseif(wpml_getLanguage()=='it'); ?>
---do function for product 45--
<?php endif; ?>
My code:
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
$product_id = 22;
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
}
}
}

Answer 1

You can easily get this by using the native WPML variable ICL_LANGUAGE_CODE.
You can find more information about this topic on the following page:

Answer 2

This can be dropped into functions.php
add_action( 'init', 'add_product_on_language' );
function add_product_on_language(){
if ( ! is_admin() ) {
if( ICL_LANGUAGE_CODE == 'en' ){
$product_id = 22;
} elseif ( ICL_LANGUAGE_CODE == 'it' ) {
$product_id = 45;
}
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
// if no products in cart, add it
WC()->cart->add_to_cart( $product_id );
}
}
}
