Magento 2：爲什麼我的自定義裝運不可見？

Question

我有一個自定義的運輸模塊，我最近與日期選擇器模塊結合，現在運輸選項在結帳頁面上不可見。我修改了​​3210文件以合併來自兩個模塊的兩個配置，所以我想知道是否這是導致衝突的原因。 datepicker完美工作，但我甚至沒有看到控制檯中的自定義裝運選項加載。

配置：

<?xml version="1.0"?> 
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Store:etc/config.xsd">

     <active>1</active>

     <price>18</price> 
     <model>SR\DeliveryDate\Model\Carrier\Customshipping</model>

Answer 1

所以，這個問題是一個簡單的語法錯誤。我有$method->setCarrier('example');，而我需要承運人設置爲我的運輸代碼protected $_code = 'icacustomshipping';
