This is my front controller  file:

            $method = $actions_list[$module_action];
            $this->$method();

		$page = (int)$_GET['page'];

        $comments = MyModComment::getProductComments((int)$this->product->id, $limit_start, $limit_end);
        //$comments = Db::getInstance()->executeS('SELECT * FROM `'._DB_PREFIX_.'mymod_comment` WHERE `id_product` = '.(int)$this->product->id.' ORDER BY `date_add` DESC LIMIT '.(int)$limit_start.','.(int)$limit_end);

        $this->setTemplate('module:mymodcomments/views/templates/front/list.tpl');
    }
}
?>

Here are the codes from my front controller file and Smarty template file from my module.

These worked in PrestaShop 1.6 but are not functioning in PrestaShop 1.7.7.5. I have already made several modifications to adapt to PrestaShop 1.7, but I am still encountering errors. Can anyone help, please?

The error screenshot is attached.

Hi, you error message is clear you need to pass variables in an array

$this->context->smarty->assign([
                'comments' => $comments,
                'product' => $this->product,
                'page' => $page,
                'nb_pages' => $nb_pages
            ]
);

Hi sir, thank you for your response.

I have already tried this, but the error persists. I'm not sure what is wrong with the code. I have debugged and checked the values in the template, and they are already assigned as an array.

                'nb_pages' => $nb_pages
            ]
);

 

Finally I got this that I should pass "'page' => $page," as array so I did this like: 'page' => array ($page), because After commenting this code the template was loading properly.
But now I am facing this error:

(1/1) ContextErrorException

Notice: Undefined index: meta

Now I don't know how to resolve it. Please help. Thanks in Advance.
