Hello , How I can make Login page that want from every Guest to type his username and password and after he Sign In , to be redirected to the website and then he can see the content in the website . (if he is a Guest ,he see only the Login Form window)
You can try "yii2-app-advanced" project template, which provides you with a set of common user management features like logging in, signing up, resetting password, … etc.
Or you may try "yii2-app-practical" series from kartik-v. (google it please).
