I have added a custom field in Magento Admin Customer edit section and want to send that value to custom function. But not sure how to do this?

I have followed this tutorial - https://webkul.com/blog/tab-with-form-in-admin-customer-edit-magento-2-0/

Below is my code -

<?php
namespace MyCustom\Customadmin\Block\Adminhtml\Customer\Edit;

use Magento\Customer\Controller\RegistryConstants;
use Magento\Ui\Component\Layout\Tabs\TabInterface;
use Magento\Backend\Block\Widget\Form;
use Magento\Backend\Block\Widget\Form\Generic;
/**
 * Customer account form block
 */
class Tabs extends Generic implements TabInterface
{
    protected $_systemStore;
    protected $_coreRegistry;

    public function __construct(
        \Magento\Backend\Block\Template\Context $context,
        \Magento\Framework\Registry $registry,
        \Magento\Framework\Data\FormFactory $formFactory,
        \Magento\Store\Model\System\Store $systemStore,

        array $data = []
    ) {
        $this->_coreRegistry = $registry;
        $this->_systemStore = $systemStore;
        parent::__construct($context, $registry, $formFactory, $data);
    }

    public function getCustomerId()
    {
        return $this->_coreRegistry->registry(RegistryConstants::CURRENT_CUSTOMER_ID);
    }

    public function getTabLabel()
    {
        return __('Password Change');
    }

    public function getTabTitle()
    {
        return __('Password Change');
    }

    public function canShowTab()
    {
        if ($this->getCustomerId()) {
            return true;
        }
        return false;
    }

    public function isHidden()
    {
       if ($this->getCustomerId()) {
            return false;
        }
        return true;
    }

    public function getTabClass()
    {
        return '';
    }

    public function getTabUrl()
    {
        return '';
    }

    public function isAjaxLoaded()
    {
        return false;
    }
    public function initForm($rowcom)
    {
        if (!$this->canShowTab()) {
            return $this;
        }
        /**@var \Magento\Framework\Data\Form $form */
        $form = $this->_formFactory->create();
        $form->setHtmlIdPrefix('myform_');

        $fieldset = $form->addFieldset('base_fieldset', ['legend' => __('Password Change')]);

            $fieldset->addField(
                'demo_field',
                'text',
                [
                    'name' => 'demo_field',
                    'data-form-part' => $this->getData('target_form'),
                    'label' => __('Enter New Password'),
                    'title' => __('Enter New Password'),
                    'value' => $rowcom,
                ]
            );
        $this->setForm($form);
        return $this;
    }

    protected function _toHtml()
    {
        if ($this->canShowTab()) {
            $this->initForm('test test ');
            return parent::_toHtml();
        } else {
            return '';
        }
    }

}

Here I am passing value to $this->initForm('test test ');

But I want that user should ad this value and this store in the database. How can we do this?

I want to set that textbox value as customer password.

public function setPassword(){
        $customerId = $this->_coreRegistry->registry(RegistryConstants::CURRENT_CUSTOMER_ID);
        $password = 'testpassword@123';

        $customer = $customerRepository->getById($customerId);
        $random = $objectManager->get('Magento\Framework\Math\Random');
        $newPasswordToken = $random->getUniqueHash();
        $customerSecure = $customerRegistry->retrieveSecureData($customer->getId());
        $customerSecure->setRpToken($newPasswordToken);
        $customerSecure->setRpTokenCreatedAt((new \DateTime())->format(\Magento\Framework\Stdlib\DateTime::DATETIME_PHP_FORMAT));
        $customerSecure->setPasswordHash($encryptor->getHash($password, true));
        $customerRepository->save($customer);
    }

You could create a plugin for the class Magento\Customer\Controller\Adminhtml\Index\Save

create a method afterExecute handle the post data and persist your data.

http://devdocs.magento.com/guides/v2.0/extension-dev-guide/plugins.html

  • but if I dont pass value in $this->initForm('test test '); it is getting me error that $rowcom is not defined. as function need arguments. How can I handle this ? Also there is no afterExecute method in Magento\Customer\Controller\Adminhtml\Index\Save – Rahul Feb 19 '18 at 11:03
  • First of all, you need to understand how plugins work. Please read the link devdocs.magento.com/guides/v2.0/extension-dev-guide/… – Thiago Lima Feb 19 '18 at 11:32
  • I have override class Save and method execute but How to access custom field value ? – Rahul Feb 19 '18 at 11:58
  • $subject->getRequest()->getPost('demo_field'); – Thiago Lima Feb 19 '18 at 12:14
  • I have overirde class Save in my custom module. But its not working. where is $subject object. please check updated question. – Rahul Feb 19 '18 at 12:44
