尝试这样运行，验证结果。此外，确保有足够的帖子给你结果。

好的，根据法典，如果你使用tax_query 在WP\\u Query的参数中，它将更改post_type 从…起posts 到any, 但如果post\\u类型exclude_from_search 设置为true 那么它仍然不会包括在any. 因此，由于我们不知道portfolio post\\u类型上的配置是什么，我建议您明确指示查询搜索这两种类型posts 还有你的portfolio_post_type.

$args = array(
    //you\'ll need to put in the correct post-type for your portfolio items.
    //the codex says that if you use \'tax_query\' that post_type should default to \'any\'
    //but for the sake of it, try this...
    \'post_type\' => array( \'posts, portfolio_post_type\' ),
    \'post_status\' => \'publish\',
    \'posts_per_page\' => -1,
    \'orderby\' => \'date\',
    \'tax_query\' => array(
        \'relation\' => \'OR\',
        array(
            \'relation\' => \'AND\',
            array(
                \'taxonomy\' => \'category\',
                \'field\'    => \'term_id\',
                \'terms\'    => array( 16 ),
                \'operator\' => \'IN\'
            ),
            array(
                \'taxonomy\' => \'category\',
                \'field\'    => \'term_id\',
                \'terms\'    => array( 19 ),
                \'operator\' => \'NOT IN\'
            ),
        ),
        array(
            \'relation\' => \'AND\',
            array(

                \'operator\' => \'IN\'
            ),
            array(
                \'taxonomy\' => \'portfolio_category\',
                \'field\'    => \'term_id\',

衷心希望这能有所帮助。
