在Woocommerce 3中以编程方式设置自定义运费 [英] Set custom shipping rates programmatically in Woocommerce 3

问题描述

我搜索并找到了许多有关更改运费的示例.基本上，我希望这样做，但是我想使用第三方API.

I have searched and found a number of examples of how to change the shipping rates. Basically I am looking to do the same, but I want to use a 3rd party API.

我已经设置了一个带有functions.php的自定义插件并激活了它.我认为使用的是这样简单的东西:

I have set up a custom plugin with a functions.php and activated it. I think used something simple like this:

add_filter('woocommerce_package_rates','test_overwrite',10,2);
function test_overwrite($rates,$package) {

    echo "<h2>Can you see me</h2>";
    foreach ($rates as $rate) {
        //Set the price
        $rate->cost = 1000;
        //Set the TAX
        $rate->taxes[1] = 1000 * 0.2;
    }
    return $rates;
}

但是，当我运行结帐或购物篮时，过滤器似乎没有运行，因为我看不到echo.我也尝试过print_r().

However when I run either the checkout, or basket, the filter does not seem to run because I cannot see the echo. I also tried print_r().

我为什么不能运行此过滤器时缺少了什么?

Am I missing something as to why I cannot run this filter ?

推荐答案

由于这是一个筛选器，并且由于已缓存数据，因此print_r()无法获得任何输出.

As this is a filter and as the data is cached, you can't get any output with print_r().

使其正常工作的正确方法如下:

The correct way to make it work is the following:

add_filter( 'woocommerce_package_rates', 'custom_shipping_costs', 20, 2 );
function custom_shipping_costs( $rates, $package ) {
    // New shipping cost (can be calculated)
    $new_cost = 1000;
    $tax_rate = 0.2;

    foreach( $rates as $rate_key => $rate ){
        // Excluding free shipping methods
        if( $rate->method_id != 'free_shipping'){

            // Set rate cost
            $rates[$rate_key]->cost = $new_cost;

            // Set taxes rate cost (if enabled)
            $taxes = array();
            foreach ($rates[$rate_key]->taxes as $key => $tax){
                if( $rates[$rate_key]->taxes[$key] > 0 )
                    $taxes[$key] = $new_cost * $tax_rate;
            }
            $rates[$rate_key]->taxes = $taxes;

        }
    }
    return $rates;
}

代码进入您的活动子主题(活动主题)的function.php文件中.

Code goes in function.php file of your active child theme (active theme).

经过测试，可以正常工作.

Tested and works.

有时候，您可能需要刷新运输方式:
1)首先清空购物车.
2)进入运输区域"设置，然后禁用/保存并重新启用/保存相关的运输方法.

Sometimes, you should may be need to refresh shipping methods:
1) Empty cart first.
2) Go to shipping Zones settings, then disable/save and re-enable/save the related shipping methods.
