如何从“woocommerce_cart_item_removed”钩子中找出产品ID？

Question

I have code

add_action( 'woocommerce_cart_item_removed', 'after_remove_product_from_cart' );
function after_remove_product_from_cart($removed_cart_item_key, $instance) {
    $product_id = $removed_cart_item_key['product_id'];
}

I want to find out a way to get product id or actual product object itself using $removed_cart_item_key. How do you do it? I cannot find any references, thanks.

Answer 1

should be something like this...

add_action( 'woocommerce_cart_item_removed', 'after_remove_product_from_cart', 10, 2 );
function after_remove_product_from_cart($removed_cart_item_key, $cart) {
    $line_item = $cart->removed_cart_contents[ $removed_cart_item_key ];
    $product_id = $line_item[ 'product_id' ];
}
