how to create a password page?

[Mr.Curiosity]

just wonder, is there a way to create a page that needed a password to open them?

[shokinro]

create a page to check authentication by checking $cookie object
add following code at beginning of your page

if (!$cookie->isLogged()) Tools::reditect("authentication.php?back=yournewpage");

if you are using 1.4x, it is better to follow new pages structure, use Page Controller.
in that case, you only need to set following in your new page controller

here is the example of history

   public function __construct()
   {
       $this->auth = true;
       $this->php_self = 'history.php';
       $this->authRedirection = 'history.php';
....

[Mr.Curiosity]

can I make certain CMS page to be password protected? so we have to login to view them.
and where can I find page controller?
did you mean in
/ sites / mywebsite.com / www / [controllers]

[shokinro]

yes, the page controller is under following folder

YourStoreRoot/controllers

but if you only want to apply it on some CMS page, you will need to check the CMS id first then set authentication or redirect
