"Email address already used" on checkout

-- url of the page with the problem -- :
-- HikaShop version -- : HikaShop Essential: 2.3.0
-- Joomla version -- : 2.5.19
-- PHP version -- : 5.3.28
-- Browser(s) name and version -- : Chrome 34.0.1847.116 m
-- Error-message(debug-mod must be tuned on) -- : Email address already used

It is a requirement for this site that users can checkout with having to register or login. We need to collect contact information, including email address (for order status notifications) and postal address (for delivery). Some customers may already have an account on the site, as we're running a membership subscription package, so this rules out using the option for Guest Registration because we get the "Email address already used" error when a Joomla account already exists for that email address. I don't seem to have an option (Configuration ~ System ~ Checkout ~ Registration) for checking out with no registration. I've seen this option referenced in several forum posts, is it available in Hika Shop Essentials?

Note that if you want to have a checkout without registration, you'll probably find your answer through this thread :

If you want to enable your customer to checkout without registering, you'll just have to
- Go to "Hikashop->System->Configuration->Checkout"
- Set the "Display method for registration" option to All in one page
- Set the "Registration" option to Guest

Note that the Registration / Display method for registration options are only available through an Hikashop commercial version, so YES you'll have to use a commercial version to do that .

Thank you for your reply. I had followed those instructions but when I attempt to checkout using an email address which already exists for an account setup in Joomla, I get the error about Email address already used.

I am using a commercial version (Essentials)

Hi,

Indeed it's the way it's working currently. If an email has already be used, it's not possible to checkout as guest.
To remove that check it will require the edition of a core file, the class "user" so php knowledge are needed.

Your support is dead ? Where is the solution? Bought the paid version and it is not finished completely !
To remove the authorization is also not an option, no email, no user notification to the administrator. How to fix it.

try to remove all in red,for me it works

administrator/components/com_hikashop/classes/user.php

if($simplified==2){
$this->database->setQuery('SELECT * FROM '.hikashop_table('user').' WHERE user_email = '.$this->database->Quote($userData->user_email));
$userInDB = $this->database->loadObject();
if(@$userInDB->user_cms_id){
JError::raiseWarning('', JText::_('EMAIL_ADDRESS_ALREADY_USED'));
return false;
}

Hello

I am trying to get this to work and really could do with some help. I would like the option when people check out as per this page.

I have attached a screen shots of the problem. How it is set out is perfect however I would like people to be able to checkout using guest even if they have registered. This is why this error message is coming up because I have already registered.

Many thanks
Iain

Hi Nicolas

Thanks for that, would I remove or change this code?

Morning,

Thanks for that however I do not have that complete piece of code. Below is an extract of the code,

else if($mode == 2) {
			$userData->user_email = $registerData->email;

			$query = 'SELECT * FROM '.hikashop_table('user').
					' WHERE user_email = '.$this->database->Quote($userData->user_email);
			$this->database->setQuery($query);
			$userInDB = $this->database->loadObject();

			if(@$userInDB->user_cms_id) {
				$ret['status'] = false;
				$ret['messages'][] = array(JText::_('EMAIL_ADDRESS_ALREADY_USED'), 'warning');
				return $ret;
			}

			$ret['user_id'] = (isset($userInDB->user_id) ? (int)$userInDB->user_id : 0);

			if(!empty($ret['user_id'])) {
				$userInDB->user_created_ip = hikashop_getIP();
				$this->save($userInDB);
			} else {
				$ret['user_id'] = $this->save($userData);
			}

			$query = 'UPDATE '.hikashop_table('address').' AS hk_addr '.
					' SET hk_addr.address_published = 0 '.
					' WHERE hk_addr.address_user_id='.(int)$ret['user_id'].' AND hk_addr.address_published = 1';
			$this->database->setQuery($query);
			$this->database->query();

if(@$userInDB->user_cms_id) {
				$ret['status'] = false;
				$ret['messages'][] = array(JText::_('EMAIL_ADDRESS_ALREADY_USED'), 'warning');
				return $ret;
			}

Hi Nicolas

Okay, let me start with the problem.

If a registered customer returns but doesn't want to log in and check out as guest they can't.

??How???
"That would lead to the possibility of anyone knowing the email address of somebody buying on your website able to get the addresses attached to that email address, which is precisely why we don't allow for that."

I can not see how anyone would be able to get the addresses attached to an account since it won't let them log in, they would be checking out as guest, ergo no addresses saved.

Cheers
