User Contributed Notes

  1. 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.”

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

    if ( is_user_logged_in() ) {
    	echo 'Welcome, registered user!';
    } else {
    	echo 'Welcome, visitor!';
  3. Example: From your functions file, this code displays a personal message for logged in users.

     * Give a personalized message for logged in users and a generic one for anonymous visitors
    function wpdocs_personal_message_when_logged_in() {
    	if ( is_user_logged_in() ) {
    		$current_user = wp_get_current_user();
    		printf( 'Personal Message For %s!', esc_html( $current_user->user_firstname ) );
    	} else {
    		echo( 'Non-Personalized Message!' );
    add_action( 'loop_start', 'wpdocs_personal_message_when_logged_in' );
