Magento 2：以编程方式添加产品属性

如何以编程方式创建类型为：文本区域的Magento 2产品属性。

以编程方式添加产品属性概述

• 步骤1：建立档案 InstallData.php
• 步骤2：定义install() 方法
• 步骤3：建立自订属性

步骤1：建立档案InstallData.php

我们将从位于以下位置的InstallData类开始

app/code/Mageplaza/HelloWorld/Setup/InstallData.php. 

该文件的内容：

<?php
namespace Mageplaza\HelloWorld\Setup;

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

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

}

步骤2：定义install（）方法

<?php

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{

}

步骤3：创建自定义属性 以下是所有InstallData.php以编程方式创建产品属性的代码行。

<?php
namespace Mageplaza\HelloWorld\Setup;

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

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'sample_attribute',
            [
                'type' => 'int',
                'backend' => '',
                'frontend' => '',
                'label' => 'Sample Atrribute',
                'input' => '',
                'class' => '',
                'source' => '',
                'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
                'visible' => true,
                'required' => true,
                'user_defined' => false,
                'default' => '',
                'searchable' => false,
                'filterable' => false,
                'comparable' => false,
                'visible_on_front' => false,
                'used_in_product_listing' => true,
                'unique' => false,
                'apply_to' => ''
            ]
        );
    }
}

如您所见，所有addAttribute方法所需的是：我们要添加属性的实体的类型ID属性的名称一组用于定义属性的键值对数组，例如组，输入类型，源，标签…

完成所有操作后，请运行升级脚本php bin / magento setup：upgrade以安装该模块，然后将创建产品属性sample_attribute。

如果要删除产品属性，可以使用方法removeAttribute代替addAttribute。它将是这样的：

编辑：

要卸载，请创建app / code / Mageplaza / HelloWorld / Setup / Uninstall.php。

<?php
namespace Mageplaza\HelloWorld\Setup;

use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\Setup\UninstallInterface;

class Uninstall implements UninstallInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory)
    {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    public function uninstall(SchemaSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->removeAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'sample_attribute');
    }
}
