以上是我的短代码。问题是：当我添加行时get_the_excerpt 在代码块内部，wpautop 之后停止工作。移除后get_the_excerpt, 一切都恢复正常了。

有人知道如何解决这个问题吗？

while ($latest->have_posts()): $latest->the_post();
    //$excerpt = get_the_excerpt(); // This doesn\'t work

    // Let\'s do it like the get_the_excerpt filter function in the core does
    // Once we get the excerpt by alternate means, everything else works again
    // See get_the_excerpt in /wp-includes/post-template.php
    $post = get_post();
    $excerpt = $post->post_excerpt;

    // Choose what to do based on whether it\'s empty or not
    if ($excerpt != \'\') echo $excerpt;
    else echo \'some fallback\';
endwhile;
