'Number' of post, out of 'Total Number of Posts'

Much gratitude for the quick reply, but I’m afraid it’s not really what I was after. I probably wasn’t clear enough.

I think your code’s in relation to a ‘paged archive’ flow, where as, what I need is in a ‘single post’ flow.

I’ll try to demonstrate, the following being the basis of each ‘single project’ post:

Project 1
[number] 1 of 3 [total]
Content
next >

Project 2
[number] 2 of 3 [total]
Content
< prev / next >

Project 3
[number] 3 of 3 [total]
Content
< prev

It’s the project ‘number’, or count, I’m trying to get (I already have the total).

This code (from a previous Support topic) seemed to be working, but then I get unexpected results. The 1st and 2nd ‘project’ output ‘1 of n’ and ‘2 of n’ respectively, but then the count seems to reset, with the rest of the ‘projects’ outputting as ‘0 of n’.

function Get_Post_Number($postID){
	$temp_query = $wp_query;
	$postNumberQuery = new WP_Query('orderby=date&order=<strong>DESC</strong>&posts_per_page=-1');
	$counter = 1;
	$postCount = 0;
	if($postNumberQuery->have_posts()) :
		while ($postNumberQuery->have_posts()) : $postNumberQuery->the_post();
			if ($postID == get_the_ID()){
				$postCount = $counter;
			} else {
				$counter++;
			}
	endwhile; endif;
	wp_reset_query();
	$wp_query = $temp_query;
	return $postCount;
}

Hopefully that makes my issue a little clearer. Any thoughts?

Thanks again!

$postNumberQuery = new WP_Query('orderby=date&order=<strong>DESC</strong>&posts_per_page=-1');

should be:

$postNumberQuery = new WP_Query('orderby=date&order=DESC&posts_per_page=-1');

You can also pick up the total number of posts returned from the query itself: $my_tot_posts = $wp_query->max_num_pages;. So then all you need to do is increment a post count variable within your Loop to get `x of n posts.

Does that help at all?

I had removed that <strong> mistake already.

One thing I did change in the above code, was the WP_Query to an array (felt it an easier way to swap-out properties). This could possibly be what caused the weird ‘reset’ I mentioned above (if I got the code wrong).

I just re-copied the code, simply adding 'post_type=projects' and minus the <strong> tag, and the ‘increment per individual project’ I was after now works!

Could you possibly go through the Get_Post_Number function, in layman terms? I think when I said I was confident in PHP, I was a little overzealous ??

Seriously, Esmi, thanks for your time!

Update: The ‘weird reset’, where the projects went from ‘1 of n’ to ‘2 of n’ then the rest were ‘0 of n’ seems to have be caused by removing '&posts_per_page=-1' from that original code. Not sure why.

Why run a separate function? Why not simply modify the Loop in the page itself:

$postNumberQuery = new WP_Query('orderby=date&order=DESC&posts_per_page=-1');
$counter = 0;
$my_tot_posts = $wp_query->max_num_pages;
if($postNumberQuery->have_posts()) :
while ($postNumberQuery->have_posts()) : $postNumberQuery->the_post();
$counter++;?>
<h2><?php the_title();?></h2>
<?php echo $counter . ' of ' . $my_tot_posts;
the_content();
endwhile; endif;
wp_reset_query();

That seems like a much better idea! Although, your code outputs:

‘1 of 02 of 03 of 04 of 05 of 06 of 07 of 08 of 0’

What does the 'posts_per_page=-1' do?

Although, your code outputs…

Well it was pretty much off the top of my head – so I’m not surprised that it needs tweaking. ??

What does the ‘posts_per_page=-1’ do?

Overrides the default posts per page configured in Settings->Reading so that the query pulls all of the relevant posts into the page.

Nice one!

Will update this post with code soon, for future reference – when I get my head around it ;D

Cheers, Esmi.

Get some sleep!

Hi guys – just wondering if you ever solved this?

If so, would you mind posting the code for me to take a look at?

In terms of the ‘counting posts’ functionality, here’s what I got to, but still not 100% sure of the code:

function Get_Post_Number( $postID ) {
	$temp_query = $wp_query;
	$postNumberQuery = new WP_Query('post_type=projects&orderby=date&order=DESC&posts_per_page=-1');
	$counter = 1;
	$postCount = 0;

	if( $postNumberQuery->have_posts()):
		while ($postNumberQuery->have_posts()):
			$postNumberQuery->the_post();

			if ($postID == get_the_ID()){
				$postCount = $counter;
			} else {
				$counter++;
			}
		endwhile;
	endif;

	wp_reset_query();
	$wp_query = $temp_query;
	return $postCount;
}

$currentID = get_the_ID();
$currentNumber = Get_Post_Number($currentID);
echo $currentNumber;

And the following, for the ‘total number of post’ functionality:

$numprojects = wp_count_posts( 'projects' );
echo $numprojects->publish; ?>

I actually ended up finding (after a lot of digging) this post that helped me out:

https://www.transformationpowertools.com/wordpress/continuous-post-numbers

After putting his function setup in my function.php file, I took his php and mashed it up with some other code that I found (unfortunately I can’t remember where i found it), and ended up with this for the between my previous and next buttons in my single.php file:

<?php
$num_posts = wp_count_posts( 'post' );
$num_posts = $num_posts->publish; //publish, draft
$num_posts = sprintf( number_format_i18n( $num_posts ) );
echo '<p>project ' . get_post_meta($post->ID,'incr_number',true) . ' of ' . $num_posts . '</p>';
?>

The result now shows up as eg:
project 3 of 37

hope that helps.
