如何在.tpl文件prestashop中使用php

Question

I just integrated a web-marchant plugin on my prestashop website, and one of the requirement of the web marchant is that i show a message either error or success message after an order as been submitted.So from the url i can get the action if successful or not. And from what i have read from around here i need to change

this :

require_once(_PS_SMARTY_DIR_.'Smarty.class.php');

global $smarty;
$smarty = new Smarty();

to this:

require_once(_PS_SMARTY_DIR_.'SmartyBC.class.php');

global $smarty;
$smarty = new SmartyBC();

And this i already did,then i added this to the page i want to display the response i get from the $_GET[] variable.

{php}
/**
*@authour 
*@return Order response
*4/15/2015
**/
    echo urldecode(base64_decode($_GET['gtpay_error']));
    echo '<br>';
    echo urldecode(base64_decode($_GET['gtpay_tranid']));
{/php}

but still no luck,it output the code as it is.What might i be doing please. Thanks in advance

Now this is the php script am adding to the page:

{php}
        {$smarty.get.gtpay_error}
    {urldecode(base64_decode($smarty.get.gtpay_error))};
    {'<br>'}
    {urldecode(base64_decode($_GET['gtpay_tranid']))};
{/php}

then it throws error:

Parse error: syntax error, unexpected '=' in /home/thelibra/public_html/tools/smarty/SmartyBC.class.php(464) : eval()'d code on line 2

Try this :

{$smarty.get.gtpay_error}

$_GET is a reserved variable for Smarty, check this link for more information : http://www.smarty.net/docsv2/en/language.variables.smarty.tpl
