Question

I am setting a custom session in the catalog/controller/checkout/cart.php controller. All it does, it checks if a value is set or not.

if (isset($this->request->post['no_tax']) && $this->request->post['no_tax'] == '1') 
{
   $this->session->data['no_tax'] = true;
} 
elseif (isset($this->request->post['no_tax']) && $this->request->post['no_tax'] === '0') 
{
   unset($this->session->data['no_tax']);
}

I can then access this in the catalog/model/shipping/totalbased.php model file,

isset($this->session->data['no_tax'])

The problem is, I need to send additioanl information in the order to the admin, which is done in the catalog/model/checkout/order.php

I’ve done a check in there:

if(isset($this->session->data['no_tax']) )
{
   //do something
}
$mail->send();

The do something, simply adds a PDF. The problem is, the PDF isn’t attached.

In the error.txt, I get: 2012-05-14 14:42:11 - PHP Notice: Undefined index: no_tax in /var/www/vhosts/site.com/httpdocs/catalog/order.php

Can I access the session this way?

Thanks

The code looks fine from what I can see, and yes you can access the data like you’ve shown. The error you’ve had looks like you have tried to access the session data directly at some point without checking it’s set, causing the notice
