PrestaShop: Redirect to homepage if the product didn't exists

i'm trying to redirect page like this :

[To see links please register here]

i want that every page, with deleted id_product - will be redirected to my homepage:

which means : i want to redirect "https://www.cdsoft.co.il/index.php?id_product=XXX"

how to do it in the htaccess file ?

Maybe this will be helpful.

Edit file `controllers/front/ProductController.php`, line `91` or find `Tools::displayError('Product not found')`, and change this for this:

`header("Location: /");`

I propose the @Labradorcode idea, but with the correct approach.
Make an ovverride of ProductController.php in `rootofps/override/controllers/front/ProductController.php`, so you have to create a new file in that directory (for rootofps I mean the install directory of PrestaShop), the content of that file is written below:

class ProductController extends ProductControllerCore {
public function init(){
FrontController::init();

if ($id_product = (int)Tools::getValue('id_product')) {
$this->product = new Product($id_product, true, $this->context->language->id, $this->context->shop->id);
}

if (!Validate::isLoadedObject($this->product)) {
header('HTTP/1.1 404 Not Found');
header('Status: 404 Not Found');
header('Location: '.$this->context->link->getPageLink('index', array('id_product', Tools::getValue('id_product'))));
} else {
parent::init();
}
}
}

In this case the redirect works if the product is totally removed and not if is disabled.

After you have created the file delete this file `rootofps/cache/class_index.php`
