Sort Posts on a Custom Field’s Value?
-
What a great plugin…worked effortlessly. And in doing so, revealed a shortfall of the content I’m trying to sort.
The shortcode as set for the page I linked: [a-z-listing post-type=”post” taxonomy=”category” terms=”restaurant-reviews”]
In short, it’s using the Post’s Title and sorting on that. But what I’d like to do is use a post’s custom-field ‘Restuarant’ and sort-on and display that value.
It it possible with this plugin? Thanks a bunch – again, super easy, slick, nice job!
The page I need help with: [log in to see the link]

Hi,
You can override the index letter for each post by hooking the
a_z_listing_item_indicesfilter.function override_the_a_z_index_letter( $indices, $item ) { if ( 'expected_post_type' !== $item->post_type ) { return $indices; } $meta = get_post_meta( $item->ID, 'your_meta_key', true ); $idx = mb_substr( $meta, 0, 1, 'UTF-8' ); // replace the current indices - if you just want to add it as an additional index // add the value to a new item in $indices rather than overwriting $indices entirely $indices = array( $idx => array( array( 'title' => $item->post_title, // or use the value in $meta - this is shown as the post title in the listing 'item' => $item, ), ), ); // I really need to improve this so you don't need to add all that boiler plate // but instead just return the indices. For the future. return $indices; } add_filter( 'a_z_listing_item_indices', 'override_the_a_z_index_letter', 10, 2 );References:
