Force Users To Login Before Reading Posts in WordPress

If your blog has some restricted area that you don’t want to publicize to all visitors, just for members only, then you might want to force users to login before reading these posts. Fortunately, WordPress has a built-in function which can help us to do that.

The function is auth_redirect(), this is how it works: When it is called from a page, it checks to see if the user viewing the page is logged in. If the user is not logged in, they are redirected to the login page. The user is redirected in such a way that, upon logging in, they will be sent directly to the page they were originally trying to access.

By using this function, we can implement our code that check if post is restricted or not, and redirect users to login page if needed.

Just paste the following code into your theme’s functions.php file:

Change the array of post IDs to fit your requirement. After that, open the header.php file and put the following code in the very top:

The code is simple, but you can expand it with more options like: require login in some specific categories, make an option page for easy input post IDs, etc.

The function auth_redirect() is available since WordPress 1.5.
