在 WordPress 主题中显示 single.php 模板的帖子摘录

Question

我在新主题中显示帖子摘录时遇到问题，因为它不支持帖子摘录，所以我必须手动添加它。但由于我是编码新手，我不知道该怎么办。我应该在哪里添加代码以及应该使用什么代码？

通过一些搜索，我发现我必须在主题的 single.php 文件中使用 get_the_excerpt 函数。但我不知道把它放在哪里以及实际使用什么线。 我尝试添加在网上搜索时找到的行，但没有一个起作用。

我想将摘录文本放在帖子特色图片下方。

提前致谢。

Answer 1

我发现我找错地方了。 我必须编辑 Template-parts 文件夹中的 content-single.php 文件。

我在帖子摘录中使用了此代码：

        <div class="entry-content"><?php the_excerpt();?>
    <?php if ( $_post = get_post() ) {
    setup_postdata( $post = $_post );
    the_excerpt();
    wp_reset_postdata();
    } ?>
    </div>

在 the_content 上方插入摘录代码。

我使用 WP Subtitle 插件和此 API 代码在 the_title 下插入帖子字幕：

        <?php do_action( 'plugins/wp_subtitle/the_subtitle', array(
         'before'        => '<p class="subtitle">',
         'after'         => '</p>',
         'post_id'       => get_the_ID(),
         'default_value' => ''
          ) ); ?>
