Hello friends.

Just to remind you that I'm really new to programming.

I am developing an application where users must create their account before logging into the application.

Now I'm at the stadium, I have to make some restrictions.

I mean that when the user has not yet logged in, their actions are limited on the site.

Let me explain. Suppose I have an Apply button. When the client clicks on this button, normally if he is not logged in, I want a message to tell him that he is not logged in. If possible add the link to redirect him to the login page .

If the client is already connected, normally he should be able to Apply.

Please help me.
