Add Navigation Between Manufacturers in Prestashop

Do you have manufacturer module active in your prestashop online store ? If your answer is yes, then you may wondering how to add "Next" and "Prev" buttons in the manufacturer page to navigate between them ?
Is there a simple way or have to override module prestashop especially the manufacturer class in order to have "Next" and "Prev" buttons.

To achieve this override ManufacturerController.php file putting it in overrides/controller/front/
and put that code in :

class ManufacturerController extends ManufacturerControllerCore
{
   
    protected function assignOne()
    {
        $data = Manufacturer::getManufacturers(false, $this->context->language->id, true, false, false, false);
        $this->manufacturer->description = Tools::nl2br(trim($this->manufacturer->description));
        $nbProducts = $this->manufacturer->getProducts($this->manufacturer->id, null, null, null, $this->orderBy, $this->orderWay, true);
        $this->pagination((int)$nbProducts);

        $products = $this->manufacturer->getProducts($this->manufacturer->id, $this->context->language->id, (int)$this->p, (int)$this->n, $this->orderBy, $this->orderWay);
        $this->addColorsToProductList($products);
        $prev = false;
        $next = false;
        for ($i=0; $i<count($data); $i++){
            if ($this->manufacturer->id == $data[$i]['id_manufacturer']){
                if ($i > 0) $prev = $data[$i-1];
                if ($i < count($data)-1) $next = $data[$i+1];
            }
        }
        $this->context->smarty->assign(array(
            'prev' => $prev,
            'next' => $next,           
            'nb_products' => $nbProducts,
            'products' => $products,
            'path' => ($this->manufacturer->active ? Tools::safeOutput($this->manufacturer->name) : ''),
            'manufacturer' => $this->manufacturer,
            'comparator_max_item' => Configuration::get('PS_COMPARATOR_MAX_ITEM'),
            'body_classes' => array($this->php_self.'-'.$this->manufacturer->id, $this->php_self.'-'.$this->manufacturer->link_rewrite)
        ));
    }

}

Then in your manufacturer.tpl you can use {$next} and {$prev}. Don't forget to backup your files first.
