WordPress - Check if user is logged in

Question

I am fairly new to WordPress. On my homepage I have a navigation bar which I only want to show to people who are logged in as users.

In my header.php the function is_logged_in doesn't seem to work.

I want to place a condition in my header.php file to check if the user has logged in (and then display the navigation).

Any advice would be helpful.

Answer 1

Use the is_user_logged_in function:

if ( is_user_logged_in() ) {
   // your code for logged in user 
} else {
   // your code for logged out user 
}

Answer 2

Example: Display different output depending on whether the user is logged in or not.

<?php

if ( is_user_logged_in() ) {
    echo 'Welcome, registered user!';
} else {
    echo 'Welcome, visitor!';
}

?>
