I just achieved this by modifying archive-listing.php. It doesn’t work with pagination though!
You do have to know a bit of php, but here is the gist:
In the function archive_listing_loop(), I moved everything that was in the while(have_posts()) loop out of it, so that it was empty. I then took that code and wrapped it in this foreach:
foreach($listingsArray as $listing){
//old code in the have posts loop goes here, below the have posts loop endwhile.
}
Then, I put this code inside the while have_posts() loop:
$strippedPrice = preg_replace("/[^0-9.]/","",get_post_meta( $post->ID, '_listing_price', true ));
$listingsArray[$strippedPrice] = array(
'permalink'=> get_permalink(),
'thumbnail'=> get_the_post_thumbnail( $post->ID, 'listings' ),
'status' => wp_listings_get_status(),
'price' => get_post_meta( $post->ID, '_listing_price', true ),
'title' => get_the_title(),
'address' => wp_listings_get_address(),
'city' => wp_listings_get_city(),
'state' => wp_listings_get_state(),
'zip' => get_post_meta( $post->ID, '_listing_zip', true ),
'bedrooms' => get_post_meta( $post->ID, '_listing_bedrooms', true ),
'bathrooms' => get_post_meta( $post->ID, '_listing_bathrooms', true ),
'sqft' => get_post_meta( $post->ID, '_listing_sqft', true ),
'id' => get_the_id()
);
Then, after the endwhile, I sorted the array:
ksort($listingsArray);
Now back down in our new foreach loop, I replaced all the instances of (for example) get_the_post_thumbnail( $post->ID, ‘listings’ ) with $listing[‘thumbnail’] etc, as you can see in the array above.
This might be a bit tricky for some people, but just FYI, it is totally doable!
