Question

我试图从WooCommerce的特定产品类别中获取购物车中的商品数量。

我正在为酿酒厂做一个网站。它含有酒精和非酒精产品。所有的葡萄酒都属于“葡萄酒”的主要类别。或类别ID 34，其下有许多子类别和产品。

对于任何属于此类别的东西......我需要知道此类别下购物车中有多少件物品。如果有六瓶葡萄酒，无论它们是相同的产品ID还是6种不同的产品ID。我需要从“葡萄酒”的类别中获得6个数字。或类别ID为34。

我试过这个没有成功。

我是WooCommerce的新手，也是面向对象的新手。

由于

function cat_cart_count( $cat_name ) {

// $cat_name variable is for you normally "tshirts" or "shorts"

global $woocommerce; $cat_count = 0; 

// For each product in the cart
foreach(WC()->cart->get_cart() as $cart_item_key => $values) { 
    $_product_id = $values['product_id']; // product ID
    $_product_qty = $values['quantity']; // product quantity

    // Getting categories of the product (could be more than one)
    $terms = get_the_terms( $_product_id, 'product_cat' );

    // Checking this product has a category
    if ( $terms && ! is_wp_error( $terms ) ) { 
        $term_name = array();

        // For each category of that product
        foreach($terms as $term) {

            // Adding the category name to an array
            $term_name[] = $term->name;

            // if the product has $cat_name category
            if ( in_array( $cat_name, $term_name ) ) {

                // add 1 x product quantity to the count
                $cat_count =+ 1 * $_product_qty;
            }
        }
    }
}

Answer 1

Wordpress条件函数has_term()接受类别ID，slug，name或该值的数组。

这是做到这一点的简单方法。您的代码将更紧凑，更轻便。您可以直接使用类别ID 34 。

这是你的功能：

4*4 + 4*4 = 32
4*4 + 5*5 = 41
5*5 + 5*5 = 50
4*4 + 6*6 = 52
5*5 + 6*6 = 61
4*4 + 7*7 = 65
6*6 + 6*6 = 72
5*5 + 7*7 = 74
4*4 + 8*8 = 80
6*6 + 7*7 = 85
5*5 + 8*8 = 89
4*4 + 9*9 = 97
7*7 + 7*7 = 98
6*6 + 8*8 = 100
5*5 + 9*9 = 106
7*7 + 8*8 = 113
4*4 + 10*10 = 116
6*6 + 9*9 = 117
5*5 + 10*10 = 125
8*8 + 8*8 = 128
7*7 + 9*9 = 130
6*6 + 10*10 = 136
4*4 + 11*11 = 137
8*8 + 9*9 = 145
5*5 + 11*11 = 146
7*7 + 10*10 = 149
6*6 + 11*11 = 157
4*4 + 12*12 = 160
9*9 + 9*9 = 162
8*8 + 10*10 = 164
5*5 + 12*12 = 169
7*7 + 11*11 = 170
6*6 + 12*12 = 180
9*9 + 10*10 = 181
4*4 + 13*13 = 185
8*8 + 11*11 = 185
7*7 + 12*12 = 193
5*5 + 13*13 = 194
10*10 + 10*10 = 200

此代码经过测试且功能齐全。

使用您的功能，例如 function cat_cart_count( $cat_name ) { $cat_count = 0; // Iterating through each cart item foreach(WC()->cart->get_cart() as $cart_item) if( has_term( $cat_name, 'product_cat', $cart_item['product_id'])) $cat_count += $cart_item['quantity']; return $cat_count; } ，以显示 echo 类别ID的值：
34

试试这个我从互联网上复制了这些代码，并根据您的情况进行了更新

function check_product_in_cart() {
        global $woocommerce;
            //  id of targeted category is 5 for example

        $product_count = 0;

        // start of the loop that fetches the cart items

        foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
            $_product = $values['data'];
            $terms = get_the_terms( $_product->id, 'product_cat' );

            // second level loop search, in case some items have several categories
            foreach ($terms as $term) {
                $_categoryid = $term->term_id;
                if (( $_categoryid === 5 ) {

                    $product_count=+ 1 * $_product_qty; ;
                }
            }
        }

        return $product_count;
   }

Answer 3

使用此代码

function cat_cart_count( $cat_name ) {
    $cat_count = 0; 
    
    // Iterating through each cart item
    foreach(WC()->cart->get_cart() as $cart_item)  
        if( has_term( $cat_name, 'product_cat', $cart_item['product_id']))
            $cat_count += $cart_item['quantity'];
            
    return  $cat_count;
}
echo cat_cart_count('all-friends');
