howto find index of item in WP_Post

Hey there,

Can you perhaps share some code to demonstrate how you are currently displaying the posts?

How are the various chapters connected to each other in the back end / the database? As long as that connection can be determined somehow, showing previous / next links should be possible.

@papaworx,

Without a lot of additional information related to the specifics on the issue, support forum volunteers, in my experience (see link here also), can and will find it quite difficult to support this topic unless you Include as much Information as Possible.

That said, to output the $post use echo is a page template.

All the pages are stored as regular pages in the database with the first page of each chapter as parents and the rest as children, one level down. I can extract the top pages by making parent->0.
The code looks as follows:

			// Styled Page Selector
			$par = $post->post_parent;
			$this_ID = get_the_ID();
			if($par==0)
				$par = $this_ID;
			$page_number = $commentpress_core->nav->get_page_number( $par );
			$cPages = get_pages(  array( 'parent' => 0, 'sort_column' => 'menu_order', 'sort_order' => 'asc' ) );
			$rank = array_search ($par, array_column($cPages, 'ID'));
			
			//echo "Rank is: ".$cPages[1][0]."<br/>";
			echo get_the_title($par)."<br/>";
			echo "<a href='". get_page_link( $par ) ."'>";
			if ($par == $this_ID)
				echo "<span class='page_nav' style='font-weight:bold;'> Page ".$page_number." </span></a>";
			else
				echo "<span class='page_nav'>".$page_number." </span></a>";
			$zpages = get_pages(  array( 'child_of' => $par, 'sort_column' => 'post_order', 'sort_order' => 'asc' ) );
			foreach ( $zpages as $page ) {
				$page_ID = $page->ID;
				$page_number = $commentpress_core->nav->get_page_number( $page_ID );
				echo "<a href='". get_page_link( $page_ID ) ."'>";
				if ($page_ID == $this_ID)
					echo "<span class='page_nav' style='font-weight:bold;'>| Page ".$page_number." </span></a>";
				else 
					echo "<span class='page_nav'>| ".$page_number." </span></a>";
			}

If there were a way of uploading a small screenshot, I could show you what it looks like.

Thanks for the info>

It may help to review all of the functions using echo.

SOLVED!
I simply stepped through the WP_Post and tested for ID component, until I had the right one. There won’t be to many items.
