Limit the search of related posts by date or number?

Hi

That option is not (yet) available in the widget. In the shortcode you can use this.

[related_posts_by_tax limit_month="12"]

For the widget use this in your (child) theme’s functions.php file:

add_filter( 'related_posts_by_taxonomy_widget_args', 'my_widget_filter', 10, 2 );
function my_widget_filter( $args, $instance ) {
 
    $args['limit_month'] = 12;
     
    return $args;
}
