根据类别,每个产品向WooCommerce添加费用

Question

我已经尝试了一段时间才能使这个工作,但我没有找到任何解决方案完全符合我们的需要,而且我远非PHP专家,所以我有点迷失.

我们使用WooCommerce和WooTickets.目标是仅对"门票"类别(ID:34)中的产品增加5%的"服务费"费用.

我们找到了此代码段,根据产品类别添加固定成本:

// Add Service Fee to Category
function woo_add_cart_fee() {

$category_ID = '23';
global $woocommerce;

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 $term) {
        // 23 is the ID of the category for which we want to remove the payment gateway
        if($term->term_id == $category_ID){
         $excost = 6;
         }
         }
        $woocommerce->cart->add_fee('Service Fee', $excost, $taxable = false, $tax_class = '');
}
}
add_action( 'woocommerce_cart_calculate_fees', 'woo_add_cart_fee' );

该解决方案的主要问题是它增加了固定成本,而我们需要百分比成本.

我们还从WooThemes本身找到了这段代码片段:

/**
 * Add a 1% surcharge to your cart / checkout
 * change the $percentage to set the surcharge to a value to suit
 * Uses the WooCommerce fees API
 *
 * Add to theme functions.php
 */
add_action( 'woocommerce_cart_calculate_fees','woocommerce_custom_surcharge' );
function woocommerce_custom_surcharge() {
  global $woocommerce;

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

    $percentage = 0.05;
    $surcharge = ( $woocommerce->cart->cart_contents_total + $woocommerce->cart->shipping_total ) * $percentage;    
    $woocommerce->cart->add_fee( 'Service Fee', $surcharge, true, 'standard' );

}

但是再一次,这个解决方案存在一些问题......

1)不考虑产品类别2)它根据整个购物车价值增加费用,但它只应对"门票"产品类别中的产品增加5%的费用,而不是整个购物车

我遇到了同样的问题,并遇到了一个代码片段,它让我走上了正确的道路.对于我的生活,我找不到包含该片段的原始网站,但这是我的重写版本.

function df_add_ticket_surcharge( $cart_object ) {

    global $woocommerce;
    $specialfeecat = 86; // category id for the special fee
    $spfee = 0.00; // initialize special fee
    $spfeeperprod = 0.05; //special fee per product

    foreach ( $cart_object->cart_contents as $key => $value ) {

        $proid = $value['product_id']; //get the product id from cart
        $quantiy = $value['quantity']; //get quantity from cart
        $itmprice = $value['data']->price; //get product price

        $terms = get_the_terms( $proid, 'product_cat' ); //get taxonamy of the prducts
        if ( $terms && ! is_wp_error( $terms ) ) :
            foreach ( $terms as $term ) {
                $catid = $term->term_id;
                if($specialfeecat == $catid ) {
                    $spfee = $spfee + $itmprice * $quantiy * $spfeeperprod;
                }
            }
        endif;  
    }

    if($spfee > 0 ) {

        $woocommerce->cart->add_fee( 'Ticket Concierge Charge', $spfee, true, 'standard' );
    }

}

add_action( 'woocommerce_cart_calculate_fees', 'df_add_ticket_surcharge' );

这将为购物车中的每件商品添加5%的附加费和票类(ID:86).如果您还没有找到解决方案,我希望这会帮助您.
