Taxes apply

Hi Nicholas you are right. I'm spanish and I'm an individual too, but if you buy a physical good, and customer need an invoice, The "Agencia Tributaria" (spanish Tax Office) require us a customer valid document number (included European customers). Indeed, I don't have a VAT number but I have a DNI/NIF, that for Spanish Tax Office, it works like VAT number for this purpose.

This is the fact because I need to modify this behaviour.

Anyway, our site only allow checkout to registered users, and we have a custom field that user fill in at registration. All what I need is to access to this custom field at getTaxType() function in "currency" class, because I tried whith next code but doesn't work.

$usr_joomla = JFactory::getUser();
$ursclass = hikashop_get('class.user');
$usr_hika = $usrclass->get($usr_joomla->id,'cms'); 

Hi Nicholas, You don't understand me.

I have created in "users" table a custom field ("tipo_usuario"). This custom field stores user type (0= individuals, 1 Companies without VAT number, 2 = companies with VAT number) like I said in my previous post, this field is compulsory and user fill in when he register. The ONLY thing I need is change the "$taxType" variable returned by "getTaxType()" function placed in "currency" class, based on the value of my custom field "tipo_usuario" instead of the content of "address_vat" and "address_company" fields.

This is the reason I need access connected user id in order to access hikashop user data. Because, I'm overriding "currency" class code but when I try to get connected user data by JFactory::getUser(); function, I don't obtain anything.
Is there any other method to obtain hikashop user id ?

Regards

Thanks Nicholas. We already discarded this solution some time ago because internal organization issues. Is for this because we are trying to override getTaxType()" function.

Any way, yesterday I found in php documentation why JFactory::getUser() returns NULL value. Again, like a great programming professor of mine said "Typicaly, the most simply solution, is the best solution"
I was using:
$usr_joomla = JFactory::getUser();
Instead of:
$usr_joomla =& JFactory::getUser();

Too simply and basical error.
For us, this issue has been solved.

Again. Thank you very much for your support
