I am writing a code in the header that pertains to link rel='prev' and link rel='next' thing but I need to check if the post is multipage. I check out these global variables:

$numpages $multipage

However they don't work in header.php or outside the loop? Example code to verify in header (just a test, but it does not work):

global $wp_query;
global $numpages;
global $multipage;
If ($multipage) {
echo 'This is a multipage post';
} else {
echo 'This is not multipage';

I am wondering how to do this, can somebody help me please? Thanks.

Just inspect the current post content for '<!--nextpage-->':

function wpse_check_multi_page()
    $num_pages    = substr_count(
    ) + 1;
    $current_page = get_query_var( 'page' );
    return array ( $num_pages, $current_page );

On page 2 of 3 that returns:

    [0] => 3
    [1] => 2

On an unpaged post it returns:

    [0] => 1
    [1] => 0
