Hi, I am new in prestashop (version 1.6) and I have some problem about a link. I want to add another login link with extra parameters so that I can hide registration part from connexion page. So in nav.tpl, I added extra parameters : $link->getPageLink('my-account', true, NULL, ['params' => 'myTest'])|escape:'html':'UTF-8'} When I click on that link, It completely disappear and in AuthController (initContent) Tools:getValue('params') returns null. I don't know how to figure it out. Thanks
