如果您的命名系统是一致的，那么只需按帖子名称排序即可：

$args = array(
    \'orderby\' => \'title\', 
    \'order\' => \'ASC\',
);
$q = new WP_Query($args);
var_dump($q->request);
var_dump(wp_list_pluck($q->posts,\'post_title\'));

或者，作为pre_get_posts 过滤器（假设主查询是我们要更改的）：

add_action(
  \'pre_get_posts\',
  function ($qry) {
    if ($qry->is_main_query()) {
      $qry->set(\'orderby\',\'title\');
    }
  }
);

我认为这是一个脆弱的解决方案。一个更复杂但更可靠的方法是为您的ID保存自定义元，并按该自定义元排序。

如果您将数据保存为自定义元，请改用以下参数：

$args = array(
    \'meta_key\' => \'SKU\', // maybe sku; or whatever your KEY is
    \'orderby\' => \'meta_value\',
    \'order\' => \'ASC\',
);

我想你需要一个过滤器posts_orderby 为此，请执行以下操作：

add_filter( \'posts_orderby\', function ( $orderby, $query ) {
    if ( $query->get( \'orderby\' ) == \'zuk\' ) {
        global $wpdb;
        //$field = $wpdb->posts . \'.post_title\';
        $field = $wpdb->postmeta . \'.meta_value\';
        $order = $query->get( \'order\' );
        $orderby = $wpdb->prepare(
            \'CASE\'
            . \' WHEN LEFT(\' . $field . \', 1) = %s THEN CONCAT(%s, LPAD(SUBSTR(\' . $field . \', 2), LENGTH(~0), %s))\'
            . \' WHEN LEFT(\' . $field . \', 1) = %s THEN CONCAT(%s, LPAD(SUBSTR(\' . $field . \', 3), LENGTH(~0), %s))\'
            . \' ELSE LPAD(\' . $field . \', LENGTH(~0), %s)\'
            . \' END \' . $order
            , \'Z\', \'A\', \'0\', \'U\', \'B\', \'0\', \'0\'
        );
    }
    return $orderby;
}, 10, 2 );

$args = array(
    \'meta_key\' => \'SKU\',
    \'orderby\' => \'zuk\',
    \'order\' => \'ASC\',
);
$query = new WP_Query( $args );

（如果数据的编号始终为5位数，则可以根据长度进行排序：

add_filter( \'posts_orderby\', function ( $orderby, $query ) {
    if ( $query->get( \'orderby\' ) == \'zuk\' ) {
        global $wpdb;
        //$field = $wpdb->posts . \'.post_title\';
        $field = $wpdb->postmeta . \'.meta_value\';
        $order = $query->get( \'order\' );
        $orderby = \'LENGTH(\' . $field . \') \' . $order . \', \' . $field . \' \' . $order;
    }
    return $orderby;
}, 10, 2 );

但这显然要脆弱得多。）
