按一个自定义字段对Wordpress帖子进行排序，同时排除所有其他值

Question

i have my wordpress posts with two custom fields 'episode_number' 'season_number'

i want to select all posts with season_number=5(example) , and sort them by episode_number DESC

i've written this

            $max_season=5;
            $args = array(
            'meta_key' => 'season_number',
            'meta_compare' =>'==',
            'meta_value' => $max_season,
            'orderby' => 'episode_number',
            'order' => 'DESC',
        );
$wp_query = new WP_Query($args);

the selection based on season_number works , but i can't order them , with this code wordpress order them based on the time of publishing

anyone can help me?

Answer 1

My original answer was off the mark, I misread the question

Try something like this:

$max_season=5;
$args = array(
    'meta_key' => 'episode_number',
    'orderby' => 'meta_value_num',
    'order' => 'DESC',
    'meta_query' => array(
        array(
        'key' => 'season_number',
        'value' => array($max_season),
        'compare' => 'IN',
        )
   )
);
$wp_query = new WP_Query($args);
