我正在尝试使用插件模板文件中的\\u摘录表单，插件是wp favorite posts默认情况下，插件仅列出并显示保存的帖子标题，我已设法让它显示所有内容、税务条款、图像等，但对\\u摘录很感兴趣，添加时会发生什么<?php the_excerpt( $post_id ); ?> 代码中不断循环着最喜欢的帖子，没有摘录。
Im使用global $post 这样我就可以得到所有的信息（除了摘录）
<?php
global $post;
if (!empty($user)):
if (!wpfp_is_user_favlist_public($user)):
echo "$user\'s Favorite Posts.";
else:
echo "$user\'s list is not public.";
endif;
endif;
if ($wpfp_before):
echo "<p>".$wpfp_before."</p>";
endif;
if ($favorite_post_ids):
foreach ($favorite_post_ids as $post_id) {
$p = get_post($post_id); ?>

第一张图片使用了\\u摘录
第二张图片没有\\u摘录

你几乎没有做错什么：
\\u摘录不使用post id。
修改全局$post时，应始终将其设置回原始值您正在将get\\u post的返回值指定给代码中未使用的$p我对您的代码进行了一些修复。下面的代码只是您的代码与我的修复程序的复制粘贴，请尝试下面的代码，如果您仍然有问题，请告诉我。抱歉，我不得不更改您的代码格式。
