Magento 2：自定义属性不起作用

Question

我以编程方式创建了自定义属性。它没有显示在管理面板的产品部分。我在创建InstallData.php和Options.php文件后使用了以下命令：

php bin / magento setup：升级php bin / magento cache：clean

之后，我无法在管理员的产品部分找到自定义属性。

代码是

1 Create InstallData.php

namespace Matrixsoftware\Matrix\Setup;

use Magento\Eav\Setup\EavSetup; 
use Magento\Eav\Setup\EavSetupFactory /* For Attribute create  */;
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)
    {
        $setup->startSetup();

        /** @var EavSetup $eavSetup */
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

        $eavSetup->addAttribute(
            \Magento\Catalog\Model\Product::ENTITY,
            'thickness',/* Custom Attribute Code */
            [
                'group' => 'Product Details',/* Group name in which you want 
                                              to display your custom attribute */
                'type' => 'int',/* Data type in which formate your value save in database*/
                'backend' => '',
                'frontend' => '',
                'label' => 'Choose Thickness', /* lablel of your attribute*/
                'input' => 'select',
                'class' => '',
                'source' => 'Matrixsoftware\Matrix\Model\Config\Source\Options',
                                /* Source of your select type custom attribute options*/
                'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
                                    /*Scope of your attribute */
                'visible' => true,
                'required' => true,
                'user_defined' => false,
                'default' => '',
                'searchable' => false,
                'filterable' => true,
                'comparable' => false,
                'visible_on_front' => true,
                'used_in_product_listing' => true,
                'unique' => false
            ]
        );
         $setup->endSetup();
    }
}

2.Create Options.php

namespace Matrixsoftware\Matrix\Model\Config\Source;

use Magento\Eav\Model\ResourceModel\Entity\Attribute\OptionFactory;
use Magento\Framework\DB\Ddl\Table;

class Options extends \Magento\Eav\Model\Entity\Attribute\Source\AbstractSource
{

    protected $optionFactory;

    /*public function __construct(OptionFactory $optionFactory)
    {
        $this->optionFactory = $optionFactory;  
        //you can use this if you want to prepare options dynamically  
    }*/

    public function getAllOptions()
    {
        /* your Attribute options list*/
        $this->_options=[ ['label'=>'Select Options', 'value'=>''],
                          ['label'=>'Option1', 'value'=>'1']
                          ['label'=>'Option2', 'value'=>'2']
                          ['label'=>'Option3', 'value'=>'3']
                         ];
        return $this->_options;
    }

    public function getOptionText($value)
    {
        foreach ($this->getAllOptions() as $option) {
            if ($option['value'] == $value) {
                return $option['label'];
            }
        }
        return false;
    }

    public function getFlatColumns()
    {
        $attributeCode = $this->getAttribute()->getAttributeCode();
        return [
            $attributeCode => [
                'unsigned' => false,
                'default' => null,
                'extra' => null,
                'type' => Table::TYPE_INTEGER,
                'nullable' => true,
                'comment' => 'Custom Attribute Options  ' . $attributeCode . ' column',
            ],
        ];
    }
}

您也可以使用它，因为我以编程方式创建自定义产品属性。
