Woocommerce中基于状态和产品类别的累进购物车项目费用

Question

最近，我尝试在这个 Woocommerce 项目中使用 2 个狙击代码，我需要为特定产品类别（术语 ID：19）和特定国家/地区（佛罗里达州“FL”）设置费用

此外，我需要将此费率乘以该产品类别 (19) 中的项目。

这是我的实际代码：

add_action('woocommerce_cart_calculate_fees','woocommerce_custom_surcharge'); 
function woocommerce_custom_surcharge() {
    $category_ID = '19'; 

    global $woocommerce;


    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $state  = array('FL');


    foreach ($woocommerce->cart->cart_contents as $key => $values ) {
    // Get the terms, i.e. category list using the ID of the product

    $terms = get_the_terms( $values['product_id'], 'product_cat' );
    // Because a product can have multiple categories, we need to iterate through the list of the products category for a match
    foreach ($terms as $term) 
    {
        // 19 is the ID of the category for which we want to remove the payment gateway
        if($term->term_id == $category_ID){
    $surcharge  = 1;

    if ( in_array( WC()->customer->shipping_state, $state && ) ) {
        $woocommerce->cart->add_fee( 'State Tire Fee', $surcharge, true, '' );
    }
}

如何根据特定类别的商品和特定州的客户设置累进费用？

任何帮助将不胜感激。

有一些错误，您的代码有点过时...
下面的代码将根据特定产品类别和特定状态的购物车项目数量设置累进费用。

add_action( 'woocommerce_cart_calculate_fees', 'wc_custom_surcharge', 20, 1 );
function wc_custom_surcharge( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return; // Exit

    ## Your Settings (below) ##

    $categories      = array(19);
    $targeted_states = array('FL');
    $base_rate       = 1;

    $user_state = WC()->customer->get_shipping_state();
    $user_state = empty($user_state) ? WC()->customer->get_billing_state() : $user_state;
    $surcharge  = 0; // Initializing

    // If user is not from florida we exit
    if ( ! in_array( $user_state, $targeted_states ) )
        return; // Exit

    // Loop through cart items
    foreach ( $cart->get_cart() as $cart_item ) {
        if ( has_term( $categories, 'product_cat', $cart_item['product_id'] )  ){
            // calculating fee based on the defined rate and on item quatinty
            $surcharge += $cart_item['quantity'] * $base_rate;
        }
    }

    // Applying the surcharge
    if ( $surcharge > 0 ) {
        $cart->add_fee( __("State Tire Fee", "woocommerce"), $surcharge, true );
    }
}

代码位于活动子主题（或活动主题）的function.php文件中。 测试和工作。
