Adding dynamic fields to the product create/edit form in Magento 2 allows you to customize your product attributes and forms according to specific business needs. By incorporating dynamic fields into the admin product edit form, you can customize product information easily without modifying the core code.

In this article, we’ll walk through the detailed steps to add a dynamic field in the product create/edit form. Let’s dive in!

Step 1: Module Setup

Make sure you have the necessary module installed in your Magento 2 version.

Step 2: Create A Product Attribute

Create a file named UpgradeProductAttr.php at the following path app/code/Mageplaza/CustomAttibute/Setup/Patch/Data/UpgradeProductAttr.php. This file will be executed when you run the setup.

<?php
namespace Mageplaza\CustomAttibute\Setup\Patch\Data;
use Magento\Catalog\Model\Product;
use Magento\Catalog\Model\Product\Type;
use Magento\ConfigurableProduct\Model\Product\Type\Configurable;
use Magento\Downloadable\Model\Product\Type as DownloadableType;
use Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface;
use Magento\Eav\Model\Entity\Attribute\Source\Boolean;
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\Patch\DataPatchInterface;
use Magento\Framework\Setup\Patch\PatchRevertableInterface;
use Mageplaza\CustomAttibute\Model\Attribute\Backend\Pattern;
use Mageplaza\CustomAttibute\Model\Config\Source\CustomerGroups;


/**
* Class UpgradeProductAttr
* Mageplaza\CustomAttibute\Setup\Patch\Data
*/
class UpgradeProductAttr implements
   DataPatchInterface,
   PatchRevertableInterface
{
   /**
    * @var ModuleDataSetupInterface $moduleDataSetup
    */
   private $moduleDataSetup;


   /**
    * @var EavSetupFactory $eavSetupFactory
    */
   private $eavSetupFactory;


   /**
    * @var $savePattern
    */
   private $savePattern = Pattern::class;


   /**
    * @var $typeBoolean
    */
   private $typeBoolean = Boolean::class;


   /**
    * UpgradeProductAttr constructor.
    * @param ModuleDataSetupInterface $moduleDataSetup
    * @param EavSetupFactory $eavSetupFactory
    */
   public function __construct(
       ModuleDataSetupInterface $moduleDataSetup,
       eavSetupFactory $eavSetupFactory
   ) {
       $this->moduleDataSetup = $moduleDataSetup;
       $this->eavSetupFactory = $eavSetupFactory;
   }


   /**
    * Apply
    *
    * @return void
    * @throws \Magento\Framework\Exception\LocalizedException
    * @throws \Magento\Framework\Validator\ValidateException
    */
   public function apply()
   {
       $setup = $this->moduleDataSetup;
       /** @var EavSetup $eavSetup */
       $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);


       $eavSetup->addAttribute(
           Product::ENTITY,
           'mp_rw_customer_group',
           array_merge(
               $this->getDFOptionsProduct(),
               [
                   'type'    => 'text',
                   'backend' => $this->savePattern,
                   'label'   => 'Customer Group(s)',
                   'input'   => 'multiselect',
                   'class'   => 'mp_rw_customer_group',
                   'source'  => CustomerGroups::class,
                   'default' => null
               ]
           )
       );
   }


   /**
    * @return array
    */
   protected function getDFOptionsProduct()
   {
       $productTypes = [
           Type::TYPE_SIMPLE,
           Type::TYPE_VIRTUAL,
           DownloadableType::TYPE_DOWNLOADABLE,
           Configurable::TYPE_CODE
       ];


       return [
           'group'                   => 'Sell Product By Points',
           'global'                  => ScopedAttributeInterface::SCOPE_GLOBAL,
           'visible'                 => true,
           'required'                => false,
           'user_defined'            => false,
           'searchable'              => false,
           'filterable'              => false,
           'comparable'              => false,
           'visible_on_front'        => false,
           'used_in_product_listing' => true,
           'unique'                  => false,
           'frontend'                => '',
           'apply_to'                => join(',', $productTypes)
       ];
   }


   /**
    * @inheritdoc
    */
   public function revert()
   {
   }


   /**
    * @inheritdoc
    */
   public function getAliases()
   {
       return [];
   }


   /**
    * @inheritdoc
    */
   public static function getDependencies()
   {
       return [];
   }


   /**
    * @return string
    */
   public static function getVersion()
   {
       return '1.0.0';
   }
}

Create a file named CustomerGroups in the path: \Mageplaza\CustomAttibute\Model\Config\Source\CustomerGroups. This file will define the source of the customer group.

<?php

namespace Mageplaza\CustomAttibute\Model\Config\Source;
use Magento\Customer\Model\ResourceModel\Group\Collection;
use Magento\Eav\Model\Entity\Attribute\Source\AbstractSource;

/**
* Class CustomerGroups
* Mageplaza\CustomAttibute\Model\Config\Source
*/
class CustomerGroups extends AbstractSource
{
   /**
    * @var Collection
    */
   private $collection;


   /**
    * CustomerGroups constructor.
    *
    * @param Collection $collection
    */
   public function __construct(Collection $collection)
   {
       $this->collection = $collection;
   }

   /**
    * @return array
    */
   public function toOptionArray()
   {
       $this->_options[] = [
           'label' => __('-- Please Select --'),
           'value' => '999',
       ];


       foreach ($this->collection->toOptionArray() as $item) {
           $this->_options[] = [
               'label' => __($item['label']),
               'value' => $item['value'],
           ];
       }


       return $this->_options;
   }


   /**
    * Get all options
    *
    * @return array
    */
   public function getAllOptions()
   {
       $this->_options[] = [
           'label' => __('-- Please Select --'),
           'value' => '999',
       ];


       foreach ($this->collection->toOptionArray() as $item) {
           $this->_options[] = [
               'label' => __($item['label']),
               'value' => $item['value'],
           ];
       }


       return $this->_options;
   }
}
