Custom Post Type: Order Loop if Custom Field Exsists

Here is a thread on a similar topic, with a solution that you can adapt to your theme.

Need to run over the loop a few times (it’s not any extra queries, it just means iterating over the data a few times), but this approach should work.

<?php
$with_meta = array();

// Loop over posts just to find out which posts have the meta key
while(have_posts()) :
	the_post();

	$has_my_meta = get_post_meta( $post->ID, 'YOURFIELDNAMEHERE', true );
	if( $has_my_meta )
		// Foreach post that has the key, store the ID into the array
		$with_meta[] = $post->ID;

endwhile;

// Rewind the query
rewind_posts();

// If no IDs, just do the loop as normal
if( empty( $with_meta ) ) : 

	while(have_posts()) : the_post();
	?>

		<div class="articleContent">
			<h3><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3>
 			 <small><?php the_excerpt_rss(); ?></small>
		</div>
	<?php
	endwhile;

// Else if we have some IDs, loop over the posts skipping those not in the array
else :

	while(have_posts()) : the_post();
		if( !in_array( $post->ID, $with_meta ) )
			continue;
	?>

		<div class="articleContent">
			<h3><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3>
 			 <small><?php the_excerpt_rss(); ?></small>
		</div>

	<?php
	endwhile; 

	// Now rewind the query again so we can iterate over the posts that don't have the key
	rewind_posts();

	while(have_posts()) : the_post();
		if( in_array( $post->ID, $with_meta ) )
			continue;
	?>

		<div class="articleContent">
			<h3><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3>
 			 <small><?php the_excerpt_rss(); ?></small>
		</div>

	<?php
	endwhile;

endif;
?>

Hope that helps.. 🙂

What makes you think that?

I’m not doing any post selection, the query already exists, all i’m doing here is sorting the existing query depending on whether there’s a particular custom field present, i think that’s inline with what the original question was.

Maybe i’m reading the question differently then you are?

🙂

The query will be paged already, unless query parameters are being set prior to the code we’ve been shown, ie. the user has explicitly set the query arguments and negating to include paging parameters (or if there aren’t enough posts to page).

If we assume for a moment there is no query_posts() call prior to the code shown, then paging should be fine as is..

I understand what you’re saying .. i think i just read the question slightly differently, though there’s nothing wrong with a little forward thinking, the user may very well want all the posts sorted by the meta key/value, i simply read the question as meaning the current page, and not the totality of all the posts for the query…
