我正在尝试修改我的循环以按类别保存帖子数据。我在这个网站上找到了一些代码，这些代码根据文章的类别保存了文章的标题，并试图修改这些代码来保存文章的内容。然而，尽管get_the_title 和get_the_category 工作get_the_content 返回null。

代码如下：

if ( false === ( $q = get_transient( \'category_list\' ) ) ) {

    $args = array( 
        \'posts_per_page\' => -1
    );

    $query = new WP_Query($args); 

    $q = array();

    $body = array();

    while ( $query->have_posts() ) { 

        $query->the_post(); 

        $a = \'<a href="\'. get_permalink() .\'">\' . get_the_title() .\'</a>\';

        $post_id = get_the_ID();

        $post_id = $post->ID;

        $body[$post_id] = array();

        $body[$post_id][\'title\'] = \'<a href="\'. get_permalink() .\'">\' . get_the_title() .\'</a>\'; //works

        $body[$post_id][\'content\'] = get_the_content(\'Read more\');

        $categories = get_the_category();

        foreach ( $categories as $key=>$category ) {

            $b = \'<a href="\' . get_category_link( $category ) . \'">\' . $category->name . \'</a>\';

        }

        $q[$b][] = $post_id; // Create an array with the category names and post titles

    }


    /* Restore original Post Data */
    wp_reset_postdata();

    set_transient( \'category_list\', $q, 12 * HOUR_IN_SECONDS );
  }

编辑：以下是我如何使用$body 阵列：

foreach($q[$b] as $post) {
  echo(\'<div class="teaser"><div class="teaser-title"><a href = "">\' . $post . \'</a></div><div class="teaser-text">\'. $body[$post] . \'</div><div class="teaser-footer"><p>pemsource.org</p></div></div>\');
}

Edit2：我添加了完整的代码。当我对body进行var转储时，我得到NULL，当我对$q进行var转储时，我得到

array(3) { ["Conundrums"]=> array(1) { [0]=> string(64) "new post" } ["Tips and Tricks"]=> array(1) { [0]=> string(80) "Tips and tricks" } ["Uncategorized"]=> array(1) { [0]=> string(78) "Tips and Tricks" } }

似乎不管我如何编辑循环。我很困惑。非常感谢您的帮助

<?php
$content = apply_filters(\'the_content\', $content);
$content = str_replace(\']]>\', \']]>\', $content);
?>
