Get last added to cart product id in Woocommerce [duplicate] - php

Question

This question already has an answer here:
Get in WooCommerce cart the product ID of a cart item
(1 answer)
Closed 4 years ago.
I try all of code from google, but none of them works.
such as:
$items = WC()->cart->get_cart();
$product_id = end($items)['data']->post->ID;
For example,
shoes have two different colors: black and gray. I added black shoes, then gray shoes, I order black shoes in the end.
It should return black shoes's ID, but the code on the top will shows gray shoes's id.
I want last added product, not the last position product.

Answer 1

You can put the products into an array and pick the last one using the php end() function as follows:
global $woocommerce;
//get cart items
$items = $woocommerce->cart->get_cart();
$ids = array();
foreach($items as $item => $values) {
$_product = $values['data']->post;
//push each id into array
$ids[] = $_product->ID;
}
//get last product id
$last_product_id = end($ids);
//get product variation details
$variations = get_variation_data_from_variation_id( $last_product_id );
Then define get_variation_data_from_variation_id($item_id) as follows:
//function to get product variation
function get_variation_data_from_variation_id( $item_id ) {
$_product = new WC_Product_Variation( $item_id );
$variation_data = $_product->get_variation_attributes();
//return variation detail
return woocommerce_get_formatted_variation( $variation_data, true );
}

Answer 2

That means you probably access the cart Object before It's created, You will need to place that code inside 'wp' hook for example.
add_action('wp', function(){
$product_id = end( WC()->cart->cart_contents)['product_id'];
});

Edited
I think you were looking for product attribute IDs? Like green or blue etc.
$cart = WC()->cart->get_cart();
$variation = end($cart)['variation'];
// This will have ID, slug, count, etc.
echo json_encode( get_term_by( 'name', end($variation) , str_replace( "attribute_", "", key($variation))) );
If you are specific about you attribute like just size change it like this based on your ta
$cart = WC()->cart->get_cart();
$variation = end($cart)['variation']['attribute_pa_size'];
// This will have ID, slug, count, etc.
echo json_encode( get_term_by( 'name', $variation , 'pa_size') );
