Seconding this question. Tried changing things in class.wp-publication-archive.php to no avail.
SEems like there’s something very easy that I’m missing. I’d appreciate any help!
I wanted this as well and have just hacked the wp-publication-archive/lib/class.publication-widget.php file.
Changed the code from
if ( isset( $instance['orderby'] ) ) {
$query_args['orderby'] = $instance['orderby'];
}
to
/* if ( isset( $instance['orderby'] ) ) {
$query_args['orderby'] = $instance['orderby'];
}*/
$query_args['orderby'] = 'post_date';
$query_args['order'] = 'DESC';
Obviously only a temporary hack, maybe a better coder could integrate it into the plugin to get it working.
