添加产品属性是Commerce中最常用的操作之一。属性是解决许多与产品相关的实际任务的强大方法。向产品添加下拉列表类型属性的过程非常简单。

在此视频中：

添加一个名为clothing_material的属性，可能的值包括：棉花、皮革、丝绸、牛仔布、毛皮和羊毛
在产品视图页面上以粗体文本显示此属性
将其分配给“默认”属性集并添加限制
添加新属性

此视频面向谁？

刚开始使用Commerce的开发人员，他们需要了解如何以编程方式创建产品属性

代码示例

首先创建所需的文件夹、xml和PHP文件：

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(
    ComponentRegistrar::MODULE,
    'Learning_ClothingMaterial',
    __DIR__);

app/code/Learning/ClothingMaterial/etc/module.xml

NOTE

如果您的模块正在使用声明性架构，并且大多数模块自2.3.0之后便已使用，则应当忽略setup_version。但是，如果您有一些旧版项目，您可能会看到使用此方法。有关详细信息，请参阅developer.adobe.com。
请注意：要使此示例代码正常工作，您不需要包含setup_version ，否则InstallData.php不会执行。

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Learning_ClothingMaterial" setup_version="0.0.1"/>
</config>

app/code/Learning/ClothingMaterial/Model/Attribute/Backend/Material.php

NOTE

确保使用您项目中的属性集ID，在本例中是数字9。

<?php
declare(strict_types=1);

namespace Learning\ClothingMaterial\Model\Attribute\Backend;

use Magento\Catalog\Model\Product;
use Magento\Eav\Model\Entity\Attribute\Backend\AbstractBackend;
use Magento\Framework\Exception\LocalizedException;

class Material extends AbstractBackend
{
    /**
     * @param Product @object
     * @throws LocalizedException
     */
    public function validate($object)
    {
        $value =$object->getData($this->getAttribute()->getAttributeCode());
        // Be sure to validate that your ID number it is likely to be different

        if (($object->getAttributeSetId() == 9) && ($value == 'fur')) {
            throw new LocalizedException(__('Bottoms cannot be fur'));
        }
    }
}

app/code/Learning/ClothingMaterial/Model/Attribute/Frontend/Material.php

<?php
declare(strict_types=1);

namespace Learning\ClothingMaterial\Model\Attribute\Frontend;

use Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend;
use Magento\Framework\DataObject;

class Material extends AbstractFrontend
{

    public function getValue(DataObject $object): string
    {
        $value = $object->getData($this->getAttribute()->getAttributeCode());
        return "<b>$value</b>";
    }

}

app/code/Learning/ClothingMaterial/Model/Attribute/Source/Material.php

<?php
declare(strict_types=1);

namespace Learning\ClothingMaterial\Model\Attribute\Source;

use Magento\Eav\Model\Entity\Attribute\Source\AbstractSource;

class Material extends AbstractSource
{
    /**
     * Get all options
     *
     * @retrun array
     */
    public function getAllOptions(): array
    {
       if(!$this->_options){
           $this->_options = [
               ['label'    => __('Cotton'),     'value' => 'cotton'],
               ['label'    => __('Leather'),    'value' => 'leather'],
               ['label'    => __('Silk'),       'value' => 'silk'],
               ['label'    => __('Fur'),        'value' => 'fur'],
               ['label'    => __('Wool'),       'value' => 'wool'],
           ];
       }
       return $this->_options;
    }
}

<?php
