WooCommerce扩展WC_Shipping_Method错误:未找到类"WC_Shipping_Method" [英] WooCommerce Extending WC_Shipping_Method error: Class 'WC_Shipping_Method' not found

问题描述

标题说明得很好.我正在尝试通过扩展类来添加新的送货方式(基于费用的送货).这是插件主体(其余部分在注释中，包含插件信息):

The title explains it pretty well. I'm trying to add a new shipping method (cost-based shipping) by extending the class. Here is the plugin body (The rest is in comments and contains the plugin info):

class WC_Cost_Based extends WC_Shipping_Method {
    function __construct() {
        $this->id = 'cost-based';
        $this->method_title = __('Cost-Based', 'woocommerce');
    }

    function calculate_shipping() {
        $rate = array(
            'id' => $this->id,
            'label' => $this->title,
            'cost' => '10.99',
            'calc_tax' => 'per_item'
            );
    // Register the rate
        $this->add_rate( $rate );
    }

}

function add_cost_based_method( $methods ) {
    $methods[] = 'WC_Cost_Based';
    return $methods;
}

add_filter('woocommerce_shipping_methods', 'add_cost_based_method');

文件保存在.../wp-content/cost-based

The file is saved in .../wp-content/cost-based

知道为什么会弹出此错误吗?

Any idea why this error is popping up?

推荐答案

导航至- https://github.com/woocommerce/woocommerce/blob/master/includes/abstracts/abstract-wc-shipping-method.php

将所有内容复制到php文件中，并替换为- wp-content/plugins/woocommerce/includes/abstracts/

copy everything in the php file and replace in the file -abstract-wc-shipping-method.php found in- wp-content/plugins/woocommerce/includes/abstracts/
