在WooCommerce购物车中获取购物车项目的产品ID [英] Get in WooCommerce cart the product ID of a cart item

问题描述

$cart_item = $woocommerce->cart->get_cart(); 

我有上面的代码.

如果我在cart_item上运行print_r，则会得到一个多维数组:

if I run print_r on cart_item I get a multi dimensional array:

Array(    [a6292668b36ef412fa3c4102d1311a62] => Array        (            [product_id] => 6803

如何仅获取product_id?

How do I get the product_id only?

我尝试了$ test = $cart_item['data'];

I tried $test = $cart_item['data'];

print_r($test);

没用.

推荐答案

要获取foreach循环中每个购物车商品的 product ID (对于简单产品):

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'];
}

如果是可变产品，请获取 variation 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'];
}

或在两种情况下(其中 $cart_item['data'] 是 WC_Product Woocommerce 3+中的对象):

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
    }
}

更新:在循环外使用产品ID

Update: Using Product ID outside the loop

1)打破循环(仅获得购物车的第一个商品ID(产品ID)):

foreach( WC()->cart->get_cart() as $cart_item ){
    $product_id = $cart_item['product_id'];
    break;
}

您可以直接使用购物车中第一项的$product_id变量.

You can use directly $product_id variable of the first item in cart.

2)使用产品ID阵列(购物车中的每个商品一个).

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'];
}

• 要获取第一项产品ID: $products_ids_array[0];
• 要获取第二项产品ID: $products_ids_array[1]; 等…
• To get the 1st item product ID: $products_ids_array[0];
• To get the 2nd item product ID: $products_ids_array[1]; etc…

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:

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
    }
}

当购物车商品为商品变体时，我们总是使用$cart_item['product_id']作为父变量商品.

We always use $cart_item['product_id'] as we get the parent variable product when a cart item is a product variation.

产品变体不处理任何自定义分类法，即产品类别和产品标签

Product variations don't handle any custom taxonomy as product categories and product tags
