下面的代码旨在简单地循环浏览帖子，给它们添加html格式的机会，然后将它们返回到短代码位置。我有条件逻辑，它根据传入的“类别”（术语）定义格式。我需要在同一页上输出两次，但我只看到在循环之外添加的代码。

add_shortcode(\'my_shortcode\',\'generate_my_shortcode_content\');
function generate_my_shortcode_content($atts){
    $a = shortcode_atts( array(
        \'post-count\' => 3,
        \'category\' => \'default-cat\'
    ), $atts );

    $post_count = (int)$a[\'post-count\'];

    $post_category = explode(\',\', $a[\'category\']);

    $args = array(
        \'post_type\' => \'my-type\',
        \'posts_per_page\' => $post_count,
        \'tax_query\' => array(
            array(
                \'taxonomy\' => \'my-taxonomy\',
                \'field\'    => \'slug\',
                \'terms\'    => $post_category
            )
        )
    );

    $test = "<h1>";

    $query = new WP_Query( $args );
    if($query->have_posts()):while($query->have_posts()):$query->the_post();

        $post_id = get_the_ID();
        $post_title = get_the_title($post_id);
        $post_content = get_the_content($post_id);

        $posts .= $post_id . $post_title . $post_content;
        $test .= "this is a test";

    endwhile;wp_reset_postdata();endif;

    $test .= "</h1>";
    return $posts . $test;
}

此函数将返回{Post ID}{Post Title}{Post Content}<h1>this is a test</h1> 第一次执行时，但只会返回<h1></h1> 在第二个。为什么会这样？

$query = new WP_Query( $args );
if( $query->have_posts() ):

    foreach( $query->posts as $post ):

        $post_id = $post->ID
        $post_title = get_the_title($post_id);
        $post_content = get_the_content($post_id);

        $posts .= $post_id . $post_title . $post_content;
        $test .= "this is a test";

    endforeach;

endif;
