mod stops working after upgrade to 1.25 to 1.31

[bartman]

We used to be able to display the price of the product in the meta title on the product page by using the following

modified

header.php in the root directory

as follows

$header_tpl = 'header.tpl';

if(file_exists(_PS_THEME_DIR_ . 'header_' . $page_name . '.tpl'))
{
   $header_tpl = 'header_' . $page_name . '.tpl';
}

$smarty->display(_PS_THEME_DIR_. $header_tpl); 

so instead of header.tpl being called on the product page header_product.tpl is called

in header_product.tpl i have the following

    <title>
{$meta_title|escape:'htmlall':'UTF-8'} - {convertPrice price=$product->getPrice(true, $smarty.const.NULL, 2)}
</title>

this works in 1.25 but breaks in 1.31 with the error

 PHP Fatal error:  Call to a member function getPrice() on a non-object in /home/firestri/public_html/tools/smarty/compile/%.^2E6^2E61960E%%header_product.tpl.php on line 11

any pointers would be appreciated

From the error message, it seems that $product is not defined. It isn't included in header.php by default. Did you modify the file and add code like the following?

$product = new Product($_GET['id_product'], true, intval($cookie->id_lang);
$smarty->assign('product', $product);

no, nothing in header.php, had a quick look in init.php and can not see anything odd their, I have another prestashop 1.25 site running will apply mod and see if it works, but looking at the code now, I am suprised it worked

Just modded a 1.25 site with the files, only made the mods mentioned above and it works fine

no mod to product.php except the cnage to the call for header.tpl

mod in action here

will have another look @ init.php and see if anything is different there
