I have a post that I would like to split in to 5 pages and depending on which page the user is on the image at the top of the page needs to change.

So page 1 of the Post displays the image in custom field image_1, then page 2 displays the image in custom field 2 and so on...

I've set up my custom fields for the post but can't find reference to the function for detecting what page the user is on so I can add the function in to my template, what is the function I should be using?

  • can you share the codes where you have spilt the single post into five? – Maruti Mohanty Oct 3 '13 at 14:24
  • It's just using the standard <!--nextpage--> code – Vince Pettit Oct 3 '13 at 14:25

Current post page can be detected using get_query_var('page');.

note that if you do not pass any page the page 1 is shown, but get_query_var('page'); will be 0;

So in your function.php you can add:

function get_page_image() {
  global $post;
  if ( ! is_object($post) || ! isset($post->ID) ) return;
  $page = get_query_var('page');
  if ( empty($page) ) $page = 1;
  $field = 'image_' . $page;
  return get_post_meta($post->ID, $field, true);
}
