Email variables names not replaced by its values ( only some email accounts )

[garciasanchezdani]

Hi all,

We have developed one new email template, named 'pending_documentation'.

Ok, in this PrestaShop instance, when new order is made, the customer receive one email with this template, due to this order changes itself to this order state: pending_documentation

Everything is ok, and email is arriving well in most of cases, but in some cases emails arrives to the customer with variables names, instead of variables values.

For example:

Someone can explain to me what's going on?

Summary, we prepare one array named $mail_vars, with all custom variables, like:

$mail_vars = array(
 '{producto_precio}'       => Tools::displayPrice($amount, $currency) . ' /' . $this->module->l('mes'),
 .
 .
 .
);

And then, we use this:

$this->module->validateOrder(
  $cart->id,
  $payment_status,
  $amount,
  $module_name,
  null,
  $mail_vars,
  $currency_id,
  false,
  $secure_key
);

To validate the order, and send the mail with the $mail_vars.

Everything is ok, but I don't understand why it happens.

Thanks you very much in advance.

Did you end up working out what was causing the intermittent nature of this problem?

Yes mate!

It was incredible. The problem was emails introduced by customer, with some letter in uppercase.

So the fix was make lowercase of each email, before sending the email.

Hope it helps to you.

Best regards.

OMG. Just changed one of my test accounts to a mixed case, and BAM, the problem occurred! Fantastic find. I'll go and fix my customer accounts. By any chance do you know if a bug has already been raised for this issue?

Thanks for the reply!
