WP_Query orderby date not working

Question

I have a simple WP_Query to get a list of posts of co-author (taxonomy author) order by date, this is the query :

$username = get_the_author_meta( 'login', $author_id );
$args = array(
  'post_type' => 'any',
  'orderby' => 'date',
  //'orderby' => 'post_date',
  'order'   => 'DESC',
  'tax_query' => array(
    array(
      'taxonomy' => 'author',
      'field' => 'name',
      'terms' => $username
      )
  )
);
$query = new WP_Query( $args );

The result is always a list of posts ordering by date ASC... I have already search solution over internet without success... Any idea ?

Thanks a lot

Answer 1

This will definitely work....It worked for me...

$username = get_the_author_meta( 'login', $author_id );
$args = array(
    'post_type' => 'any',
    'orderby' => 'date',
    'order'   => 'DESC',
    'suppress_filters' => true,
    'tax_query' => array(
     array(
           'taxonomy' => 'author',
           'field' => 'name',
           'terms' => $username
          )
     )
);
                
$query = new WP_Query( $args );

Adding

'suppress_filters' => true

into the $args array did sorting in the order I needed.

If you're using the Post Types Order plugin, you may need to add the following to your query args:

'ignore_custom_sort' => true,
