Get in WooCommerce cart the product ID of a cart item
提问by Kevin.a
$cart_item = $woocommerce->cart->get_cart();
I have the above code.
我有上面的代码。
if I run print_r on cart_item I get a multi dimensional array:
如果我在cart_item 上运行print_r，我会得到一个多维数组：
Array( [a6292668b36ef412fa3c4102d1311a62] => Array ( [product_id] => 6803
How do I get the product_id only?
如何仅获取 product_id？
I tried $test = $cart_item['data'];
我试过 $test = $cart_item['data'];
print_r($test);
Didn't work.
没用。

To get the product IDof each cart item in the foreach loop (for a simple product):
要获取product IDforeach 循环中每个购物车项目的 ，（对于简单产品）：
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:
如果它是可变产品，要获得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 theWC_ProductObject in Woocommerce 3+):
或者对于这两种情况（Woocommerce 3+ 中$cart_item['data']的WC_Product对象在哪里）：
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
更新：在循环外使用产品 ID
1) Breaking the loop (Just to get the first item ID (product ID) of cart):
1）打破循环（只是为了获得购物车的第一个项目ID（产品ID））：
foreach( WC()->cart->get_cart() as $cart_item ){
$product_id = $cart_item['product_id'];
break;
}
You can use directly $product_idvariable of the first item in cart.
您可以直接使用$product_id购物车中第一件商品的变量。
2) Using an array of product IDs (one for each item in cart).
2) 使用一组产品 ID （购物车中的每件商品一个）。
$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…
- 要获取第一个项目产品 ID：
$products_ids_array[0]; - 要获取第二项产品 ID：
$products_ids_array[1];等等...
To check product categoriesor product tagsin cart item use WordPress has_term()like:
要检查购物车项目中的产品类别或产品标签，请使用 WordPress，has_term()例如：
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
$cart_item['product_id']当购物车项目是产品变体时，我们总是使用as 我们获取父变量产品。产品变体不处理任何自定义分类作为产品类别和产品标签
