    Please note that is_user_logged_in is a pluggable function and you could get a fatal error if you call it too early.

    To solve this problem, you can wrap the login check within a function hooked to the init action:

    function example_function()
{
	if ( is_user_logged_in() ) 
	{
		// code
	}
}
add_action('init', 'example_function');

<?php } else { ?>

    This function is more accurate if used at, or after, the ‘template_redirect’ Action. Before that, under unusual circumstances, it will give unexpected results.

    The most common case is for a Site Address (URL) without a “www.” when an http:// request is received with a “www.” specified.

    Background: between the ‘wp’ and ‘template_redirect’ Action, the Rewrite rules are applied for Pretty Permalinks. During this process, $_SERVER[‘SERVER_NAME’] is corrected in the common case listed above by removing “www.”

You must log in before being able to contribute a note or feedback.
