Prestashop 1.4.9: An account is already registered with this e-mail - prestashop

Question

I reported a bug in prestashop community at http://forge.prestashop.com/browse/PSCFI-6967 yesterday. Do anybody suggest me any fix for it?

Answer 1

Well since you haven't posted minor version, I've took the first and the last minor versions and diffed them (Customer.php class to be precise).
This is 1.4.0.1:
static public function customerExists($email, $return_id = false)
{
if (!Validate::isEmail($email))
die (Tools::displayError());
$result = Db::getInstance()->getRow('
SELECT `id_customer`
FROM `'._DB_PREFIX_.'customer`
WHERE `email` = \''.pSQL($email).'\'');
if ($return_id)
return intval($result['id_customer']);
else
return isset($result['id_customer']);
}
And this is 1.4.8.3:
public static function customerExists($email, $return_id = false, $ignoreGuest = true)
{
if (!Validate::isEmail($email))
die (Tools::displayError());
$result = Db::getInstance()->getRow('
SELECT `id_customer`
FROM `'._DB_PREFIX_.'customer`
WHERE `email` = \''.pSQL($email).'\''
.($ignoreGuest ? 'AND `is_guest` = 0' : ''));
if ($return_id)
return (int)($result['id_customer']);
else
return isset($result['id_customer']);
}
The thing is, that you are using something in between these two and closer to the lower one.
As you can see the later one has another optional parameter $ignoreGuest which defaults to true. Hence every validation is bypassed.
You can do either one of these two things:
Upgrade to the latest version of 1.4 (http://code.google.com/p/prestashop/downloads/detail?name=prestashop_1.4.8.3.zip&can=2&q=) if any of your components are not compatible with 1.5. If they are - go all the way to the latest.
If on the other hand you just need a quick and dirty fix: change the function in Customer class to the second one in this answer.
