问题描述
我想根据 woocommerce 的购物车数量计算自定义运费,我的要求如下,
购物车数量
- 0-10 => 4.99 英镑(shipping_rate_id = flat_rate:12),
- 10-20 => 3.99 英镑(shipping_rate_id = flat_rate:13),
- 20-30 => 2.99 英镑(shipping_rate_id = flat_rate:14),
- 30-40 => 1.99 英镑(shipping_rate_id = flat_rate:15),
- 超过 40 => 免费送货(shipping_rate_id = flat_rate:17)
注意:我们不计算烟草类别的运费。如果有人购买烟草物品,烟草 商品价格不用于运费计算。为了实现这一点,所有的烟草项目 添加到免费送货类别(id = 150)。
add_filter('woocommerce_package_rates','custom_shipping_rates_based_on_shipping_class',11,2);
function custom_shipping_rates_based_on_shipping_class($rates,$package) {
if (is_admin() && !defined('DOING_AJAX'))
return;
// HERE define your shipping class to find
$class = array(150);
// HERE define the shipping method to change rates for
$shipping_rate_ids = array('flat_rate:12','flat_rate:13','flat_rate:14','flat_rate:15');
// Initialising
$item_price = $item_qty = $item_total = 0;
// Loop through cart items
foreach($package['contents'] as $cart_item_key => $cart_item) {
$item_shipping_class_id = $cart_item['data'] - > get_shipping_class_id();
if (!in_array($item_shipping_class_id,$class)) {
$item_price += $cart_item['data'] - > get_price(); // Sum line item prices that have target shipping class
$item_qty += $cart_item['quantity']; // Sum line item prices that have target shipping class
$item_total = $item_price * $item_qty;
}
}
// Loop through shipping rates
foreach($rates as $rate_key => $rate) {
if (in_array($rate_key,$shipping_rate_ids)) {
if ($item_total > 0 && $item_total < 10) {
$rates[$rate_key] - > cost = 4.99;
unset($rates['flat_rate:13']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:15']);
unset($rates['flat_rate:17']);
}
elseif($item_total > 10.01 && $item_total < 20) {
$rates[$rate_key] - > cost = 3.99;
unset($rates['flat_rate:12']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:15']);

}

unset($rates['flat_rate:12']);
unset($rates['flat_rate:13']);
unset($rates['flat_rate:15']);
unset($rates['flat_rate:17']);

unset($rates['flat_rate:12']);
unset($rates['flat_rate:13']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:17']);
} else {
$rates[$rate_key] - > cost = 0;
unset($rates['flat_rate:12']);
unset($rates['flat_rate:13']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:15']);
}
}
}
return $rates;
}
以上代码并不适合所有场景,请帮助我。
解决方法
如果您知道每种运输方式的 shipping_rate_id 值,则意味着在 WooCommerce 插件中(WooCommerce > 设置 > 运输 > 运输区域 > 编辑 > 运输方式)您已经创建并分配了运输成本(或免费)适用于每种运输方式。
因此您无需再次更改每一项的成本。
另外,对于免费送货,运费 ID 将为 free_shipping:17
而不是 flat_rate:17
。
除非您创建了零成本送货方式(统一费率而不是免费送货).
工作代码将是:
add_filter('woocommerce_package_rates','change_shipping_method_based_on_cart_total',11,2);
function change_shipping_method_based_on_cart_total( $rates,$package ) {
// set the shipping class id to exclude
$shipping_class_id = 150;
// initializes the total cart of products
$total_cart = 0;
foreach ( WC()->cart->get_cart() as $cart_item ) {
$product = $cart_item['data'];
// if the product has the shipping class id equal to "$shipping_class_id" it is excluded from the count
if ( $product->get_shipping_class_id() == $shipping_class_id ) {
continue;
}
$qty = $cart_item['quantity'];
$price = $cart_item['data']->get_price();
// add the product line total to the total
$total_cart += $price * $qty;
}
switch ( true ) {
case $total_cart < 10: // £4.99
// only the "flat_rate:12" shipping method will be enabled
unset($rates['flat_rate:13']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:15']);
unset($rates['flat_rate:17']); // or "unset( $rates['free_shipping:17'] );"
break;
case $total_cart >= 10 && $total_cart < 20: // £3.99
// only the "flat_rate:13" shipping method will be enabled
unset($rates['flat_rate:12']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:15']);
unset($rates['flat_rate:17']); // or "unset( $rates['free_shipping:17'] );"
break;
case $total_cart >= 20 && $total_cart < 30: // £2.99
// only the "flat_rate:14" shipping method will be enabled
unset($rates['flat_rate:12']);
unset($rates['flat_rate:13']);
unset($rates['flat_rate:15']);
unset($rates['flat_rate:17']); // or "unset( $rates['free_shipping:17'] );"
break;
case $total_cart >= 30 && $total_cart < 40: // £1.99
// only the "flat_rate:15" shipping method will be enabled
unset($rates['flat_rate:12']);
unset($rates['flat_rate:13']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:17']);
break;
case $total_cart >= 40: // free
// only the "flat_rate:17" or "free_shipping:17" shipping method will be enabled
unset($rates['flat_rate:12']);
unset($rates['flat_rate:13']);
unset($rates['flat_rate:14']);
unset($rates['flat_rate:15']);
break;
}
return $rates;
}
代码已经过测试并且可以工作。代码进入您主题的 functions.php
文件。
