Get in WooCommerce cart the product ID of a cart item
To get the product ID
of each cart item in the foreach loop (for a simple product):
foreach( WC()->cart->get_cart() as $cart_item ){ $product_id = $cart_item['product_id'];}
If it's a variable product, to get the variation ID
:
foreach( WC()->cart->get_cart() as $cart_item ){ $variation_id = $cart_item['variation_id'];}
Or for both cases (where $cart_item['data']
is the WC_Product
Object in Woocommerce 3+):
foreach( WC()->cart->get_cart() as $cart_item ){ // compatibility with WC +3 if( version_compare( WC_VERSION, '3.0', '<' ) ){ $product_id = $cart_item['data']->id; // Before version 3.0 } else { $product_id = $cart_item['data']->get_id(); // For version 3 or more }}
Update: Using Product ID outside the loop
1) Breaking the loop (Just to get the first item ID (product ID) of cart):
foreach( WC()->cart->get_cart() as $cart_item ){ $product_id = $cart_item['product_id']; break;}
You can use directly $product_id
variable of the first item in cart.
2) Using an array of product IDs (one for each item in cart).
$products_ids_array = array();foreach( WC()->cart->get_cart() as $cart_item ){ $products_ids_array[] = $cart_item['product_id'];}
- To get the 1st item product ID:
$products_ids_array[0];
- To get the 2nd item product ID:
$products_ids_array[1];
etc…
To check product categories or product tags in cart item use WordPress has_term()
like:
foreach( WC()->cart->get_cart() as $cart_item ){ // For product categories (term IDs, term slugs or term names) if( has_term( array('clothing','music'), 'product_cat', $cart_item['product_id'] ) ) { // DO SOMETHING } // For product Tags (term IDs, term slugs or term names) if( has_term( array('clothing','music'), 'product_tag', $cart_item['product_id'] ) ) { // DO SOMETHING ELSE }}
We always use
$cart_item['product_id']
as we get the parent variable product when a cart item is a product variation.Product variations don't handle any custom taxonomy as product categories and product tags
