计算特定产品类别的购物车项目

Question

我正在尝试从 WooCommerce 中的特定产品类别中获取购物车中的商品数量。

我正在为酒厂做网站。它有酒精和非酒精产品。所有葡萄酒都属于 'wine' 或类别 ID 34 的主要类别，其下还有许多子类别和产品。

对于属于该类别的任何商品...我需要知道该类别下购物车中有多少商品。如果有六瓶酒，无论它们都是相同的产品 ID 还是 6 个不同的产品 ID。我需要从 'wine' 的类别或 34 的类别 ID 中获取数字 6。

我试过了，但没有成功。

我对 WooCommerce 很陌生，对面向对象也有点陌生。

谢谢

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;
            }
        }
    }
}

试试这个我从互联网上复制了这段代码并进行了更新以适合您的情况

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;
   }

Wordpress 条件函数 has_term() 接受类别 ID、slug、名称或该值的数组。

所以这是完成它的更短和更简单的方法。您的代码将更加紧凑和轻便。您可以直接使用您的类别 ID 34.

这是你的函数：

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;
}

此代码已经过测试且功能齐全。

Usage of your function using for example echo to display the value for 34 category ID:
echo cat_cart_count( 34 );

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');
