Custom attribute for customer is not inserting data

Question

I have written the install script to insert the attribute on admin form. But when i click save it does not save the value. Below is the screen short. Prefer feel is the attribute.

Answer 1

To add an attribute to customer EAV table, we have to use 'used_in_form' proper EAV implementation of customer attribute. Please check InstallData.php code where I have created customer attribute to insert company name.

<?php

namespace [Package_Name]\[Module_Name]\Setup;

use Magento\Customer\Setup\CustomerSetupFactory;
use Magento\Customer\Model\Customer;
use Magento\Eav\Model\Entity\Attribute\Set as AttributeSet;
use Magento\Eav\Model\Entity\Attribute\SetFactory as AttributeSetFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

/**
 * @codeCoverageIgnore
 */
class InstallData implements InstallDataInterface
{
    /**
     * @var CustomerSetupFactory
     */
    protected $customerSetupFactory;

    /**
     * @var AttributeSetFactory
     */
    private $attributeSetFactory;

    /**
     * @param CustomerSetupFactory $customerSetupFactory
     * @param AttributeSetFactory $attributeSetFactory
     */
    public function __construct(
        CustomerSetupFactory $customerSetupFactory,
        AttributeSetFactory $attributeSetFactory
    ) {
        $this->customerSetupFactory = $customerSetupFactory;
        $this->attributeSetFactory = $attributeSetFactory;
    }

    /**
     * {@inheritdoc}
     */
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        /** @var CustomerSetup $customerSetup */
        $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);

        $customerEntity = $customerSetup->getEavConfig()->getEntityType('customer');
        $attributeSetId = $customerEntity->getDefaultAttributeSetId();

        /** @var $attributeSet AttributeSet */
        $attributeSet = $this->attributeSetFactory->create();
        $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);

        $customerSetup->addAttribute(Customer::ENTITY, 'customer_company', [
            'type' => 'varchar',
            'label' => 'Company',
            'input' => 'text',
            'required' => false,
            'visible' => true,
            'user_defined' => true,
            'sort_order' => 1000,
            'position' => 1000,
            'system' => 0,
        ]);

        $attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'customer_company')
            ->addData([
                'attribute_set_id' => $attributeSetId,
                'attribute_group_id' => $attributeGroupId,
                'used_in_forms' => ['adminhtml_customer','customer_account_create','customer_account_edit'],
            ]);

        $attribute->save();
    }
}

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
    $installer = $setup;
            $installer->startSetup();
    $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);

    $customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, 'prefer_feel', [
                        'type'         => 'varchar',
                        'label'        => 'Prefer Feel',
                        'input'        => 'text',
                        'required'     => false,
                        'visible'      => true,
                        'user_defined' => true,
                        'position'     => 999,
                        'system'       => 0,
                    'backend'  => '',
                    'source'   => '',
                    'default' => '',
                    'frontend' => '',
                    'unique'     => false,
                    'note'       => '',
    ]);


            $prefer_feel   = $customerSetup->getAttribute(\Magento\Customer\Model\Customer::ENTITY, "prefer_feel");

          $child1_firstname = $customerSetup->getEavConfig()->getAttribute(\Magento\Customer\Model\Customer::ENTITY, 'prefer_feel');
          $used_in_forms[]="adminhtml_customer";
          $used_in_forms[]="checkout_register";
          $used_in_forms[]="customer_account_create";
          $used_in_forms[]="customer_account_edit";
          $used_in_forms[]="adminhtml_checkout";
          $child1_firstname->setData("used_in_forms", $used_in_forms)
              ->setData("is_used_for_customer_segment", true)
              ->setData("is_system", 0)
              ->setData("is_user_defined", 1)
              ->setData("is_visible", 1)
              ->setData("sort_order", 100);

          $child1_firstname->save();
          $installer->endSetup();


    $attribute = $customerSetup->getEavConfig()->getAttribute('customer', 'prefer_feel')
        ->addData(['used_in_forms' => [
            'adminhtml_customer',
            'adminhtml_checkout',
            'customer_account_create',
            'customer_account_edit'
        ]]);
    $attribute->save();
