attributes - 如何在 Magento 2 中以编程方式将现有属性添加到属性集

Question

如何在 Magento 2 中以编程方式将一些现有属性添加到新属性集中？

Answer 1

在 magento 2 中，已经创建了 color & manufactor 属性，但是默认情况下这两个属性没有分配给默认属性集。所以，我们可以这样做。然后它会在模块安装时将这两个属性分配给默认属性。

<?php
namespace Vendor\Module\Setup;

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;
    private $categorySetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory, \Magento\Catalog\Setup\CategorySetupFactory $categorySetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
        $this->categorySetupFactory = $categorySetupFactory;
    }
    
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        try {
            /**
             * @var \Magento\Eav\Setup\EavSetup
             */
            $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

            /**
             * @var \Magento\Catalog\Setup\CategorySetup
             */
            $categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);
            
            $entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Product::ENTITY);
            $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId); // get default attribute set id 
            $attrGroupId = $categorySetup->getDefaultAttributeGroupId($entityTypeId, $attributeSetId); // get default attribute group id (in my case, it returns id of 'Product Details' group)

            $colorAttr = $eavSetup->getAttribute(\Magento\Catalog\Model\Product::ENTITY, 'color');
            if($colorAttr) {
                $eavSetup->addAttributeToGroup(
                    $entityTypeId, 
                    $attributeSetId, 
                    $attrGroupId, 
                    'color', 
                    null
                );
            }

            $manufacturerAttr = $eavSetup->getAttribute(\Magento\Catalog\Model\Product::ENTITY, 'manufacturer');
            if($manufacturerAttr) {
                $eavSetup->addAttributeToGroup(
                    $entityTypeId, 
                    $attributeSetId, 
                    $attrGroupId, 
                    'manufacturer', 
                    null
                );
            }

        } catch (NoSuchEntityException $e) {
            return;
        } catch (\Exception $e) {
            return;
        }
    }
