Could someone help me find what is wrong with this code? I am trying to learn from Prestashop Module Development book but can not pass this step. Prestashop1.6.1.10 Controller: <?php class MyModCommentsCommentsModuleFrontController extends ModuleFrontController { protected function initList() { $this->setTemplate('list.tpl'); } public function initContent() { parent::initContent(); $id_product = (int)Tools::getValue('id_product'); $module_action = Tools::getValue('module_action'); $actions_list = array('list' => 'initList'); if ($id_product > 0 && isset($actions_list[$module_action])) $this->$actions_list[$module_action](); } } Template: <h1> {l s='Comments on product' mod='mymodcomments'} "{$product->name}" </h1> And in displayProductTabContent I have link: <div class="rte"> {assign var=params value=[ 'module_action' => 'list', 'id_product'=> $smarty.get.id_product ]} <a href="{$link->getModuleLink('mymodcomments', 'comments', $params)}"> {l s='See all comments' mod='mymodcomments'} </a> </div>
