Why Check Whether a User Is Logged In to WordPress

As mentioned earlier, checking whether a user is logged in is used in many scenarios. Furthermore, it is one of the most commonly used WordPress features—and for good reason.

There are thousands of reasons why you might need to check whether a user is logged in to WordPress or to check the user's status. Here are just a few of the main ones:

• Conditionally display the log-in and log-out links in your website's header.
• Use the names of logged-in users to greet them and welcome them.
• Display WooCommerce prices only to registered users.
• Display certain pages, such as the My Account page, to registered users.

You've probably already figured out why it's helpful to check whether a user is logged in to WordPress.

Whether you want to use this for one of the reasons listed above or for some other reason, we'll show you how to tell if a user has tried to log in to WordPress.

How to Check If a User Is Logged In

WordPress has a built-in function that you can use to determine whether a user is logged in or not.

is_user_logged_in()

You can also use PHP logical operator To check if a user is NOT logged in (logged out), add an exclamation point (¡!) to the left of the function, like this:

!is_user_logged_in()

It's a simple function because it doesn't take any variables and returns true if a user is logged in and false if you are not logged in.

Next, you can perform different types of actions depending on the returned value.

For example, you can choose to greet all users logged in to WordPress with a Hi, fan message and only Hello all offline users. To do this, you can use the is_user_logged_in() at our event functions.php or template files.

Use the is_user_logged_in() function in the functions.php file

WordPress uses hooks (such as anchors) to make it easier to add content to specific parts of the page.

Therefore, you'll need to add the message to the desired hook depending on where you want it to appear.

If you want it to appear above the header, you can use the function init hooks.

Using FTP or from your WordPress dashboard, navigate to Appearance -> Theme File Editor and open the functions.php from the child theme.

Note: Back up your website before editing the core files.

Next, scroll to the bottom of the file and paste this function:

add_action(\'init\', \'greet_logged_in_users\');
function greet_logged_in_users() {
	if ( is_user_logged_in() ) {
		echo \'<p>Hello, fan!</p>\';
  } else {
    echo \'<p>Hello</p>\';
  }
}

Once you've saved the changes, visit your website and make sure you can see the message for logged-in users. Then, log out and verify that the alternative message is displayed.

If you'd rather check whether a user is logged in to WordPress within a template file, continue to the next section.

Using the is_user_logged_in() function in a PHP template file

The second way to use the function is_user_logged_in() To check whether the user is logged in, run it in a template file instead of the functions.php file.

The advantage of using a template file is that you can place the function anywhere on the page, regardless of whether there is a hook to which you can attach it.

Let's take the previous example and display a welcome message to logged-in users using one of the theme's template files.

Since we want to display the message above the header, we'll need to modify the file header.php file.

Therefore, go to Appearance -> Theme File Editor and click the button header.php from the right sidebar.

Next, place the is_user_logged_in() Place it wherever you want and save the file.

<?php
  if ( is_user_logged_in() ) {
    echo &#039;<p>Hello fan!</p>';
  } else {
    echo '<p>Hello</p>';
  }
?&gt;

Once you've saved it, visit your website and make sure the correct message is displayed based on the user's status.
