无需拆分查询或执行多个查询。只需使用参数orderby 有价值的post_type 按帖子类型进行排序。您可以使用第二个值进行额外排序，例如date. 看见Codex: Class Reference | WP_Query | Order & Orderby Parameters 了解更多信息。

您可以尝试对数据库中的所有结果执行一次查询，然后使用get_post_type() 将结果分解为每个帖子类型的单独循环。如果PHP操作比使用两个数据库查询更快，那么根据您正在使用的内容，它可能会提高性能，不过您必须自己进行测试。

<?php
$all_results = new WP_Query([
    \'post_type\' => [\'post_type_1\', \'post_type_2\'] 
]);

// initiate counter variables
$count_post_type_1s = 0;
$count_post_type_2s = 0;

while ( $all_results->have_posts() ) : $all_results->the_post();
    if( get_post_type($post) == \'post_type_1\' ) {
        // increment counter variable for post type 1 being found
        $count_post_type_1s++;
        // post_type_1 output
        the_title();
    }
endwhile;
// check if counter variable is still 0, if it is no post type 1\'s were found
if( $count_post_type_1s == 0 ) {
    echo "No post type 1\'s have been found";
}

 // Rewind posts to use same query again
$all_results->rewind_posts();

// do some stuff in between loops

while ( $all_results->have_posts() ) : $all_results->the_post();
    // increment counter variable for post type 2 being found
    $count_post_type_2s++;
    if( get_post_type($post) == \'post_type_2\' ) {
        // post_type_2 output
        the_title();
    }
endwhile;
// check if counter variable is still 0, if it is no post type 2\'s were found
if( $count_post_type_2s == 0 ) {
    echo "No post type 2\'s have been found";
}
