来自WooCommerce产品类别购物车项目计数的费用 [英] Fees based from WooCommerce product categories cart item count

问题描述

基于"和"

Based on "Minimum cart item quantity for a specific product category in WooCommerce" and "Additional price based on cart item count in WooCommerce"

我正在尝试在结帐页面中对特定产品类别中的产品进行计数，我只需要一个代码即可对其类别中的产品进行计数(如图片中所示)，并且如果购物车中有2个来自耳机"类别的产品，则添加2美元总价

I am trying to count the products from specific product categories in checkout page, i just need a code that count the products from their category like in picture and if 2 products from 'headphone' category was in the cart then add 2 $ to total price

此图片将解释所有内容:

This image will explain everything:

这是我的代码尝试:

add_action( 'woocommerce_cart_calculate_fees', 'custom_packing_fee', 10, 1 );
function custom_packing_fee( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    if ( did_action( 'woocommerce_cart_calculate_fees' ) >= 2 )
        return;

    $count = $cart->get_terms('')

    if ( $count->count >= 9 ){
        $fee = 15;
    }
    elseif( $count->count >= 6 && $count < 9 ){
        $fee = 14;
    }
    elseif( $count>count >= 4 && $count < 6 ){
        $fee = 13;
    }

    if ( isset($fee) && $fee > 0 ) {
        $label = sprintf( __('Box fee (%d items)'), $count);
        $cart->add_fee( $label, $fee, false );
    }

但这是行不通的.

推荐答案

根据您的上一个问题代码，这是对来自不同产品类别的商品进行计数的方法.如您所见，该代码紧凑，优化并且效率更高.

Based on your last question code, here is the way to count items from different product categories. As you will see, the code is compact, optimized and more efficient.

此外，您还需要了解钩子在使用时的工作原理:

Also you need to understand how hooks work when using:

• 功能 add_action( $hook_name, $function_name_to_call, $priority, $args_count )
• 功能 add_filter( $hook_name, $function_name_to_call, $priority, $args_count )

最后2个参数是可选的...默认情况下，优先级是 10 ，而自变量计数是:

The 2 last arguments are optional… By default the priority is 10 and the arguments count is:

• 0 以获取动作挂钩.
• 1 用于过滤器挂钩.

在过滤器挂钩中，始终在函数末尾返回第一个函数参数(变量).

In a filter hook, the first function argument (variable) is always returned at the end of the function.

1)为每个产品类别计数添加多个费用 (项目数量计数):

add_action( 'woocommerce_cart_calculate_fees', 'custom_packing_fees' );
function custom_packing_fees( $cart ) {
    if ( is_admin() && !defined('DOING_AJAX') )
        return;

    if ( did_action('woocommerce_cart_calculate_fees') >= 2 )
        return;

    // Initializing data (settings)
    $data = [
        ['name' => __('Cupcake'),   'threshold' => 4,   'fee' => 15,    'count' => 0],
        ['name' => __('Cake'),      'threshold' => 3,   'fee' => 11,    'count' => 0],
        ['name' => __('Macaron'),   'threshold' => 6,   'fee' => 12,    'count' => 0],
    ];

    $fee_text   = __('"%s" box fee (%d items)');

    // Loop through cart items (counting product categories)
    foreach ( $cart->get_cart() as $item ) {
        // Loop through product categories
        foreach ( $data as $key => $values ) {
            if ( has_term( $values['name'], 'product_cat', $item['product_id'] ) ) {
                // Increase the product category count (based on quantity)
                $data[$key]['count'] += (int) $item['quantity'];
            }
        }
    }

    // Loop through product categories counts
    foreach ( $data as $key => $values ) {
        // Add a fee for each product category (when the count threshold value is reached)
        if( $values['count'] >= $values['threshold'] ) {
            $cart->add_fee( sprintf( $fee_text, $values['name'], $values['count'] ), $values['fee'], false );
        }
    }
}

2)为每个产品类别计数添加多个费用 (购物车计数，而不是数量):

2) Adding multiple fees for each product category count (cart item count, not quantity):

add_action( 'woocommerce_cart_calculate_fees', 'custom_packing_fees' );
function custom_packing_fees( $cart ) {
    if ( is_admin() && !defined('DOING_AJAX') )
        return;

    if ( did_action('woocommerce_cart_calculate_fees') >= 2 )
        return;

    // Initializing data (settings)
    $data = [
        ['name' => __('Cupcake'),   'threshold' => 4,   'fee' => 15,    'count' => 0],
        ['name' => __('Cake'),      'threshold' => 3,   'fee' => 11,    'count' => 0],
        ['name' => __('Macaron'),   'threshold' => 6,   'fee' => 12,    'count' => 0],
    ];

    $fee_text   = __('"%s" box fee (%d items)');

    // Loop through cart items (counting product categories)
    foreach ( $cart->get_cart() as $item ) {
        // Loop through product categories
        foreach ( $data as $key => $values ) {
            if ( has_term( $values['name'], 'product_cat', $item['product_id'] ) ) {
                // Increase the product category count (based on cart item count)
                $data[$key]['count'] += 1;
            }
        }
    }

    // Loop through product categories counts
    foreach ( $data as $key => $values ) {
        // Add a fee for each product category (when the count threshold value is reached)
        if( $values['count'] >= $values['threshold'] ) {
            $cart->add_fee( sprintf( $fee_text, $values['name'], $values['count'] ), $values['fee'], false );
        }
    }
}

3)为所有产品类别计数添加唯一费用 (项目数量计数):

add_action( 'woocommerce_cart_calculate_fees', 'custom_packing_fees' );
function custom_packing_fees( $cart ) {
    if ( is_admin() && !defined('DOING_AJAX') )
        return;

    if ( did_action('woocommerce_cart_calculate_fees') >= 2 )
        return;

    // Initializing data (settings)
    $data = [
        ['name' => __('Cupcake'),   'threshold' => 4,   'fee' => 15,    'count' => 0],
        ['name' => __('Cake'),      'threshold' => 3,   'fee' => 11,    'count' => 0],
        ['name' => __('Macaron'),   'threshold' => 6,   'fee' => 12,    'count' => 0],
    ];

    $fee_text   = __('Box fee (%d items)');
    $fee_amount = 0;
    $total_count = 0;

    // Loop through cart items (counting product categories)
    foreach ( $cart->get_cart() as $item ) {
        // Loop through product categories
        foreach ( $data as $key => $values ) {
            if ( has_term( $values['name'], 'product_cat', $item['product_id'] ) ) {
                // Increase the product category count (based on quantity)
                $data[$key]['count'] += (int) $item['quantity'];
            }
        }
    }

    // Loop through product categories counts
    foreach ( $data as $key => $values ) {
        // Calculate the fee amount for all product categories (when the count threshold value is reached)
        if( $values['count'] >= $values['threshold'] ) {
            $fee_amount  += $values['fee'];
            $total_count += $values['count'];
        }
    }

    // The unique fee merged
    if ( $fee_amount > 0 ) {
        $cart->add_fee( sprintf( $fee_text, $total_count ), $fee_amount, false );
    }
}

代码进入您的活动子主题(或活动主题)的functions.php文件中.经过测试，可以正常工作.

Code goes in functions.php file of your active child theme (or active theme). Tested and works.
