如何使用get_content WordPress函数？

使用内容WordPress函数时，我无法获取内容

 <!-- Start the Loop. -->
 <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
    <?php if ( in_category( '3' ) ) : ?>
        <div class="post-cat-three">
    <?php else : ?>
        <div class="post">
    <?php endif; ?>
    <!-- Display the Title as a link to the Post's permalink. -->
    <h2><a href="<?php the_permalink(); ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
    <!-- Display the date (November 16th, 2009 format) and a link to other posts by this posts author. -->
    <small><?php the_time('F jS, Y'); ?> by <?php the_author_posts_link(); ?></small>
    <!-- Display the Post's content in a div box. -->
    <div class="entry">
        <?php the_content(); ?>
    </div>
    <!-- Display a comma separated list of the Post's Categories. -->
    <p class="postmetadata"><?php _e( 'Posted in' ); ?> <?php the_category( ', ' ); ?></p>
    </div> <!-- closes the first div box -->
    <!-- Stop The Loop (but note the "else:" - see next line). -->
 <?php endwhile; else : ?>
    <!-- The very first "if" tested to see if there were any Posts to -->
    <!-- display.  This "else" part tells what do if there weren't any. -->
    <p><?php esc_html_e( 'Sorry, no posts matched your criteria.' ); ?></p>
    <!-- REALLY stop The Loop. -->
 <?php endif; ?>

我真的试过了，但是得到了空的描述结果，请帮忙

下面是一个在Wordpress中从post获取描述的示例

 <?php 
$categories = get_the_category( $id );
