正如T31所说，您不能使用WP\\u Query directy来实现这一点。

您可以尝试使用“posts\\u子句”过滤器来修改WP\\u查询生成的各个SQL子句，但无论您如何操作，这都将非常棘手。

相反，替换整个SQL查询可能更容易。您可以使用get\\u tax\\u sql（）处理分类部分（未测试）：

function my_posts_request( $old_query, $wp_query ) {
    global $wpdb;

    $ptypes = $wp_query->get(\'post_type\');

    if ( \'page\' != $ptypes[2][\'post_type\'] )
      return $old_query; // This is not the WP_Query you are looking for

    // Do the conditional tax_query
    $tax_query = array(
      array(
        \'taxonomy\' => \'options\',
        \'terms\' => array( \'set-as-news-item\' ),
        \'field\' => \'slug\',
      )
    );

    $clauses = get_tax_sql( $tax_query, $wpdb->posts, \'ID\' );

    $join = "FROM $wpdb->posts {$clauses[\'join\']}";
    $where = "WHERE (
      post_type = \'aucc_publication\' OR 
      post_type = \'aucc_media\' OR 
      (post_type = \'page\' {$clauses[\'where\']})
    )";

    // Do the other tax query
    $tax_query = array(
      array(
        \'taxonomy\' => \'section\',
        \'terms\' => array( \'programs-and-services\' ),
        \'field\' => \'slug\',
      ),
      array(
        \'taxonomy\' => \'regions\',
        \'terms\' => array( \'ghana\' ),
        \'field\' => \'slug\',
      )
    );

    $clauses = get_tax_sql( $tax_query, $wpdb->posts, \'ID\' );

    $join .= $clauses[\'join\'];
    $where .= $clauses[\'where\'];

    return "SELECT $wpdb->posts.* $join $where ORDER BY post_date LIMIT 10";
}
add_filter( \'posts_request\', \'my_posts_request\' );
