$args = array(
    "post_type" => "portfolio",
    "meta_key" => "authors_name",
    "orderby" => "meta_value",
    "order" => "ASC"
);

$custom_query = new WP_Query( $args );

This Also Does Not Work

$args = array(
    "post_type" => "portfolio",
    "meta_key" => "authors_name",
        'meta_query' => array(
            array(
                'key' => 'authors_name',
            ),
            ),
            'orderby' => 'meta_value',
            'order' => 'ASC',
);

  1. I was able to sort this issue with add_filter(‘pre_get_posts’ ::: In essence this is what my script now looks like :::

    function laudes_order( $wp_query ) {
    
            $wp_query->set('meta_key', 'authors_name');
            $wp_query->set('orderby', 'meta_value');
            $wp_query->set('order', 'DESC');
    
    }
    
    add_filter('pre_get_posts', 'laudes_order');
    
    
    $args = array(
        "post_type" => "portfolio",
    );
    
    
    $custom_query = new WP_Query( $args );
