我有一个短代码，它总是在页面内容的顶部输出。我不确定在这种情况下输出缓冲区的正确用法。

下面是我的快捷码函数：

function nt_course_note_call_sca() {

    // only show logged-in members on learn dash pages
    $post_type  = get_post_type();
    $types      = apply_filters( \'learndash_notes_supported_types\', array( \'sfwd-courses\', \'sfwd-topic\', \'sfwd-assignment\', \'sfwd-lessons\' ) );

    if ( is_user_logged_in() ){

        if( in_array( $post_type, $types ) ) {

          return nt_course_note_entry_field();

        }

    }

}

add_shortcode(\'reflective_learning\', \'nt_course_note_call_sca\');

nt\\u course\\u note\\u entry\\u字段的输出

//Prints Note field in front end and retieves exisintg note as placeholder
function nt_course_note_entry_field() {

    global $post;

    //ID\'s
    $current_user       = get_current_user_id();
    $current_lesson_id  = $post->ID;
    $current_post_type  = get_post_type();

    //Checks if note exists and changes title and body variables accordingly
    $args = array(
        \'post_type\'      => \'coursenote\',
        \'post_status\'   =>  array( \'draft\', \'publish\' ),
        \'meta_query\'     => array(
            //\'relation\' => \'AND\',
            array(
                \'key\'     => \'nt-note-current-lessson-id\',
                \'value\'   => $current_lesson_id,
                \'compare\' => \'=\',
            )
        ),
         \'author\' => $current_user
    );

    $the_query = new WP_Query( $args );

    if ($the_query->have_posts()){

        while ( $the_query->have_posts() ) : $the_query->the_post();

            //$title    = get_the_title();
            $body   = get_the_content();

            //var_dump( $body );

        endwhile;

     wp_reset_postdata();

    } else {

        //$title    = __( \'Note Title\', \'sfwd-lms\' );
        $body   = __( \'\', \'sfwd-lms\' );

    } 


    // get the course title or custom field if it exisists

if( get_field(\'reflective_learning_question\', $current_lesson_id) ) {

    $title  = get_field(\'reflective_learning_question\', $current_lesson_id);



    } else {
$title  = get_the_title($current_lesson_id);
        //$title    = __( \'Note Title\', \'sfwd-lms\' );
        //$body     = __( \'\', \'sfwd-lms\' );

我如何才能防止这种输出在页面顶部并以正确的位置输出？

 ob_start();
 nt_course_note_entry_field();
 $result = ob_get_contents();
 ob_end_clean();
 return $result;
