Order by postname

Well…
If it helps, I’ve been back to your shortcode, but with some changes on the shortcode handler (which is not nice, I know, unless you add this to a future version ?? ):
###################

function a_z_shortcode_handler( $attributes ) {
        $attributes = shortcode_atts(
                array(
                        'column-count' => 1,
                        'minimum-per-column' => 10,
                        'heading-level' => 2,
                        'display' => 'posts',
                        'post-type' => 'page',
                        'taxonomy' => '',
                        'terms' => '',
                        'numbers' => 'none',
//<XXX
                'category-not-in' => '',
//XXX>

                ), $attributes, 'a-z-listing'
        );

        if ( ! empty( $attributes['taxonomy'] ) && 'terms' === $attributes['display'] ) {
                $a_z_query = new A_Z_Listing( $attributes['taxonomy'] );
                return $a_z_query->get_the_listing();
        }
//<XXX
        $excludecat = explode( ',', $attributes['category-not-in'] );
        $excludecat = array_map( 'trim', $excludecat );
        $excludecat = array_unique( $excludecat );
//XXX>

        $post_types = explode( ',', $attributes['post-type'] );
        $post_types = array_map( 'trim', $post_types );
        $post_types = array_unique( $post_types );

        $query = array(
                'post_type' => $post_types,
//<XXX
                'category__not_in' => $excludecat,
//XXX>
        );

and the shortcode example:
[a-z-listing post-type="post" taxonomy="category" terms="horses" orderby="postname" category-not-in="1,53"]

My other concern now is to index the listing based on slug and not title…
Meaning I want my posts to be sorted and grouped by letters based on slug (postname), but with titles displayed below the letters

example:
A
Mickael Andrew

D
Katie Douglas

(and the slugs being andrew-mickael, douglas-katie)

The “orderby” I used before seems not to work on “tax_query” and I don’t want to go too deep into your class ??

Thanks!

Thanks for the ideas, I’ll look to incorporate them, or a variant, in a future iteration.

I’m sorry I didn’t get to your query before you’d found a workaround that works for you. Good work on getting everything working! ??

Hi Daniel,
No pb… Thanks for the reply ??
Actually, if we could add a shortcode the way I did before last update, or if you accept in the shortcode more arguments, that would be perfect ??

Hi Daniel,
Any news about this?
Thx!
