Display User’s Name, or any of Their Other Information

I put together this very simple snippet to display a user’s name when they log in to a premium membership site. Then, to display their name, all you have to do is use the shortcode [user_first_name], and their name will appear instead (assuming it has been entered in their profile).

// DISPLAY USER'S FIRST NAME

function user_first_name() {
	global $current_user;
	get_currentuserinfo();
	$first_name = esc_attr( $current_user->user_firstname );
	return $first_name;
}

add_shortcode( 'user_first_name', 'user_first_name' );

You can take it a little further and modify this to show other information instead by taking advantage of the other variables available under $current_user. Use the following values to show more information:

• First name: user_firstname
• Last name: user_lastname
• Display name: display_name
• Username: user_login
• User email address: user_email
• User ID: ID
