I Want to show a custom field order_detail's in PaymentModule

[fix!]

I have a module to customize productos, and all is working over the backoffice, but i need to show this field value into the email order confirmation.

 

I try to modify the OrderDetail class with no success and too trying to edit the PaymentModule but the field is not appearing inside the order object, because i did try to find with this sentence but there is not my field:

 

public function hookActionValidateOrder($params)

{

session_start();

$id_order = intval($order = $params['order']->id);

// now save the session values.....

foreach($_SESSION as $data => $datavalue)

{

if($data == 'product_sessionkey')

{

foreach($datavalue as $prd_id => $key_value)

{

 

$arr = explode('-',$prd_id);

$productid = $arr[0];

$product_attribute_id = $arr[1];

$product_proyecto = $_SESSION['blablabla']['proyecto'];

$product_serial = $_SESSION['blablabla']['serial'];

 

 $upSq_ = "update  "._DB_PREFIX_."order_detail Set designer_session_id = '" .$product_serial."', url_pdf = '" .$product_proyecto."' where product_id = ".$productid ." and product_attribute_id = ".$product_attribute_id ." and id_order =".$id_order ;

$resultData = Db::getInstance()->execute($upSq_);

 

$details = $params['order'];

echo "<pre>";

print_r($details);

echo "<pre>";

 

}

}

}

die();

 

 

Please help, and thank you for your time.

fix!

Finally i found the solution through a context variable, 

 

$this->context->cookie->__set('proyecto',$_SESSION['blablabla']['proyecto']);

 

Then in PaymentModule.php:

 

$products_list .=

'<tr style="background-color: '.($key % 2 ? '#DDE2E6' : '#EBECEE').';">

<td style="padding: 0.6em 0.4em;width: 15%;">'.Context::getContext()->cookie->proyecto.'</td>

 

 

 

Thanks!
