I am trying to remove the Telephone custom field in customer account information. I am unsure how it loads the fields and how to remove a required option and field.
You can try this ...
$installer = Mage::getModel('customer/entity_setup', 'core_setup'); $installer->startSetup(); $installer->updateAttribute('customer_address','telephone', 'is_required', 0); $installer->endSetup();
