Using back office hooks

Admin controllers are useful to create a new tab. However, if you need to alter existing tabs, you will need to use hooks in the back office. In this section, we will use only some of the hooks available. It is recommended that you read the exhaustive list of hooks at the end of the book to see all the various possibilities.

if (!$this->registerHook('displayProductTabContent') ||
  !$this->registerHook('displayBackOfficeHeader') ||
  !$this->registerHook('displayAdminProductsExtra') ||
  !$this->registerHook('ModuleRoutes'))
    return false;
