建立產品屬性
新增產品屬性是中最常用的操作之一 Commerce. 屬性是解決與產品相關的許多實際任務的強大方法。 將下拉式清單型別屬性新增至產品的程式相當簡單。
在本影片中：
- 新增名為clothing_material的屬性，其可能值為：棉花、皮革、絲綢、牛仔布、毛皮和羊毛
- 以粗體文字在產品檢視頁面上顯示此屬性
- 將其指派給預設屬性集並新增限制
- 新增屬性
這部影片是給誰看的？
- 剛開始使用Commerce且需要瞭解如何以程式設計方式建立產品屬性的開發人員

程式碼範例
首先建立所需的資料夾、xml和PHP檔案：
- app/code/Learning/ClothingMaterial/registration.php
- app/code/Learning/ClothingMaterial/etc/module.xml
- app/code/Learning/ClothingMaterial/Model/Attribute/Backend/Material.php
- app/code/Learning/ClothingMaterial/Model/Attribute/Frontend/Material.php
- app/code/Learning/ClothingMaterial/Model/Attribute/Source/Material.php
- app/code/Learning/ClothingMaterial/Setup/installData.php
app/code/Learning/ClothingMaterial/registration.php
<?php
use Magento\Framework\Component\ComponentRegistrar;
ComponentRegistrar::register(

app/code/Learning/ClothingMaterial/etc/module.xml
NOTE
如果您的模組使用「宣告式結構描述」，而且大部分都使用2.3.0以後的版本，您應該省略setup_version。 不過，如果您有一些舊版專案，您可能會看到使用此方法。 另請參閱 developer.adobe.com 以取得詳細資訊。
