I created three custom field in customer account edit page and same field created in admin panel inside customer edit form.
But now, how to save data? I tried to override the editPost.php
file and use this $customer->setCustomAttribute('abc',$this->getRequest()->getParam('ABC'));
This is not help in saving data and show undefine variable "customer" error.
Notice: Undefined variable: customer in /opt/lampp/htdocs/magento/app/code/xxx/xxx/Controller/Account/EditPost.php on line 140
