我有一个自定义的帖子类型，我在其中创建了3个父子关系页面。页面的创建方式如下：父-子-孙

我希望子页面和孙页面获得与父页面相同的内容，并且我从内容区域中的仪表板添加的所有内容都要添加到父帖子内容之后。

例如，如果我的父帖子包含几行文本，而在我的子帖子中，我会再添加几行文本，这应该添加在父内容之后。

以下是创建CPT层次结构的函数：

function wpse121567_get_cpt_hierarchy() {
// Make sure it\'s the right CPT
if ( \'debate-parent\' != get_post_type() ) {
    return false;
}
// Globalize the post object
global $post;
// Parent CPT
if ( 0 == $post->post_parent ) {
    return \'debate-parent\';
}
// Not a parent CPT, so fetch current post parent
$parent = get_post( $post->post_parent );
// Child CPT
if ( 0 == $parent->post_parent ) {
    return \'debate-child\';
} else {
    return \'debate-grandchild\';
}
}

这是我的单曲{myCPT.php}：

 <div id="content" class="span9" role="main">


<?php if ( \'debate-parent\' == wpse121567_get_cpt_hierarchy() ) {
    // Normal loop here
    if ( have_posts() ) : while ( have_posts() ) : the_post();

    get_template_part( \'inc/post-format/single\', get_post_format() ); 
    endwhile; endif;
} 
// Child CPT
else if ( \'debate-child\' == wpse121567_get_cpt_hierarchy() ) {
    // Globalize post object
    the_post();
        $parent = get_post( $post->post_parent );
        echo \'<h1>\' . $parent->post_title . \'</h1>\';
        $content = apply_filters( \'the_content\', $parent->post_content ) . get_the_content();
        echo \'<div>\' . $content . \'</div>\';

    // Fetch parent CPT comments
    $parent_cpt_comments = get_comments( array(
        \'post_id\' => $post->post_parent,
        \'status\' => \'approve\'
    ) );
    // Loop through parent CPT comments
    foreach ( $parent_cpt_comments as $comment ) {
        // Output comment list markup here
    }
}
// Grandchild CPT
else if ( \'debate-grandchild\' == wpse121567_get_cpt_hierarchy() ) {
    // Comment Stats code goes here

 }
?>

    <?php 


        $enable_rtl         = of_get_option(\'enable_rtl\', false);



        if(!of_get_option(\'disable_pagination\')){

            if($enable_rtl){

                $next_post = get_adjacent_post( false, \'\', true ); 

                $prev_post = get_adjacent_post( false, \'\', false ); 

            }else{

                $next_post = get_adjacent_post( false, \'\', false ); 

                $prev_post = get_adjacent_post( false, \'\', true ); 

            }

            ?>

            <?php

        }



    // show related posts by tag

    if(!of_get_option(\'disable_related_posts\')){ 

        get_template_part( \'inc/related-posts\' );

    }





    // If comments are open or we have at least one comment, load up the default comment template provided by Wordpress

    if ( comments_open()  )

        comments_template( \'\', true );



 else{ // Well, if there are no posts to display and loop through, let\'s apologize to the reader (also your 404 error) ?>



<article class="post error">

    <h1 class="404"><?php _e(\'Page not found\', \'outbox\'); ?></h1>

</article>



<?php } // OK, I think that takes care of both scenarios (having a post or not having a post to show) ?>

</div><!-- #content .site-content -->

我的问题是，如何自动获取每个子元素上的父帖子内容，以及是否在父元素的内容之后从仪表板添加更多内容？

非常感谢。
