Show the Post Number

here is some code that automatically allocates a number to each post, starting with 1 for the oldest post, using custom fields:

I am using the numbering system for my custom post loop (for a portfolio loop). Is there a ay to add the numbers to just that loop using custom post types?

I can’t get the numbers to show up. I made a new post and still nothing. The only way the number shows up is if I manually add in a custom field for ‘incr_number’.

Here is a look at my code:


<?php include ('header-portfolio.php'); ?>

<?php

if ( get_query_var('paged') ) { $paged = get_query_var('paged'); }
elseif ( get_query_var('page') ) { $paged = get_query_var('page'); }
else { $paged = 1; }

$myposts = array(
'post_type' => 'portfolio',
'posts_per_page' => '10',
'orderby' => 'id',
'order' => 'ASC',
'paged'=> $paged
);
query_posts($myposts);
?>
<?php posts_nav_link(' · ', 'previous page', 'next page'); ?>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div class="thumbwrapper">

<div class="portfolio_post">

<h2><a
title="<?php the_title(); ?>"
href="<?php the_permalink() ?>"
rel="bookmark"><?php the_title(); ?><span><?php printf("%02d", get_post_meta($post->ID,'incr_number',true));?></span>

</h2>
<div class="portfolio_thumb">

">

<?php the_post_thumbnail(); ?>

</div>

</div>

</div>
<?php endwhile; endif; ?>

<div class="nav-previous"><?php next_posts_link( __( '« Older' ) ); ?></div>
<div class="nav-next"><?php previous_posts_link( __( 'Newer »' ) ); ?></div>

<?php wp_reset_query(); ?>

i have no idea how to restrict/change this to custom post type posts.

try and play with the post_type within this line in the code:

$querystr = "SELECT $wpdb->posts.* FROM $wpdb->posts WHERE $wpdb->posts.post_status = 'publish' AND $wpdb->posts.post_type = 'post' ";

generally, you need to echo the custom field value:

echo get_post_meta($post->ID,'incr_number',true));?></span>
