I created a login page and it has a captcha. Now I want to show captcha when user enter wrong username or password. For that I want to add a page item as a counter that has default value = 0, when user enter wrong username or password, counter becomes counter + 1 and when counter >= 1 then login page shows captcha. So what should I do for that? I have another question: Is it possible that some processes don’t execute when a page item’s type is hidden?
