我试图从WooCommerce中的特定产品类别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’或类别ID 34的主要类别,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’wine’类别或34类别ID中获得6个数字.

我试过这个没有成功.

我是WooCommerce的新手,也是面向对象的新手.

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;
            }
        }
    }
}

解决方法:

WordPress条件函数has_term()接受类别ID,段塞,名称或该值的数组.

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

这是你的功能：

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;
}

此代码经过测试且功能齐全.
