如何通过WP_Query在Wordpress中使用order by？

Question

I'm trying to put a order by inside a wp_query but I can't get it to work.

What is wrong?

$query = new WP_Query( 'cat='.get_post_meta($post->ID, 'select',1).'&orderby=menu_order');

Answer 1

Check this if it is working for you:

$args = array(
'cat' => get_post_meta($post->ID, 'select', 1),
'orderby' => 'menu_order',
'order' => 'DESC');
WP_Query($args);

Answer 2

Maybe you meant:

$query = new WP_Query(
            'cat'     = get_post_meta($post->ID, 'select',1),
            'orderby' = 'menu_order',
            'order'   = 'asc'
         );

your should pass as an array, for better readability. Also add how to order.
