这很可能有一个非常简单的解决方案。我正在使用Ixion 主题到目前为止，我真的很喜欢它的布局，我几乎准备出版了。但是，该主题设计为仅在首页显示帖子名称、帖子日期和帖子类别。我想另外加上这篇文章的摘录。我找到了在主页上填充最新帖子列表的代码（取自index.php）：

            while ( have_posts() ) : the_post();

                /*
                 * Include the Post-Format-specific template for the content.
                 * If you want to override this in a child theme, then include a file
                 * called content-___.php (where ___ is the Post Format name) and that will be used instead.
                 */
                get_template_part( \'components/post/content\', get_post_format() );

            endwhile;

然后，以下代码对组件/帖子/内容中的每篇帖子进行格式化。php：

<?php
/**
 * Template part for displaying posts.
 *
 * @link https://codex.wordpress.org/Template_Hierarchy
 *
 * @package Ixion
 */
?>

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<div class="entry-body">
    <header class="entry-header">
        <?php
            if ( has_post_thumbnail() && ! is_single() ) : ?>

            <div class="post-thumbnail">
                <a href="<?php the_permalink(); ?>">
                    <?php the_post_thumbnail( \'ixion-featured-image\' ); ?>
                </a>
            </div>

        <?php
            endif;

            if ( ! is_single() ) {
                if ( \'post\' === get_post_type() ) {
                    get_template_part( \'components/post/content\', \'meta\' );
                }
                the_title( \'<h2 class="entry-title"><a href="\' . esc_url( get_permalink() ) . \'" rel="bookmark">\', \'</a></h2>\' );
            }
        ?>
    </header>
    <div class="entry-content">
        <?php
            the_content( sprintf(
                /* translators: %s: Name of current post. */
                wp_kses( __( \'Continue reading %s <span class="meta-nav">&rarr;</span>\', \'ixion\' ), array( \'span\' => array( \'class\' => array() ) ) ),
                the_title( \'<span class="screen-reader-text">"\', \'"</span>\', false )
            ) );

            wp_link_pages( array(
                \'before\' => \'<div class="page-links">\' . esc_html__( \'Pages:\', \'ixion\' ),
                \'after\'  => \'</div>\',
            ) );
        ?>
    </div><!-- .entry-content -->

    <?php if ( is_single() ) {
        get_template_part( \'components/post/content\', \'footer\' );
    } ?>

    <?php if ( \'post\' === get_post_type() ) {
        ixion_author_bio();
    } ?>
</div> <!-- .entry-body -->

具体而言，我已经确定了负责填充每个帖子信息的函数调用，它是：

the_content( sprintf(
            /* translators: %s: Name of current post. */
            wp_kses( __( \'Continue reading %s <span class="meta-nav">&rarr;</span>\', \'ixion\' ), array( \'span\' => array( \'class\' => array() ) ) ),
            the_title( \'<span class="screen-reader-text">"\', \'"</span>\', false )
        ) );

如何修改此函数以包含博客文章的摘录？我既不是PHP开发人员，也不是WordPress开发人员，所以我肯定错过了一些东西。

谢谢
