我希望有人可以帮助我发现我的错误，因为我浪费了无数个小时。我使用具有灵活内容的高级自定义字段插件模板。我正在使用灵活的内容字段，其中包含我目前正在处理的网站上的大量模板。我使用了相同的策略，我总是用它来显示我的自定义帖子类型'学位和程序'中的所有帖子的可选自定义字段。我的灵活内容适用于我的所有页面，但我的单个自定义帖子的页面除外。我有一个页面'single-degrees-and-programs.php'，我有：
<?php while (has_sub_field("program_content")): ?>
在我的functions.php中，我已经在我的灵活内容中设置了所有字段，如下所示（希望这里有一个错误，我很遗憾，但我对此表示怀疑，因为所有灵活的字段都显示在我的自定义管理员中讯息。

有没有人知道为什么这不起作用。我真的需要帮助。
答案 0 :(得分：0)
我认为你需要：
if( have_rows('program_content') ): // Check the Flexible Content has rows
while ( have_rows('program_content') ) : the_row();
if( get_row_layout() == 'intro' ): // Check the type of each row
the_sub_field('intro_text'); // Do something with it
elseif( get_row_layout() == 'inline_image' ):
...
endif;
endwhile;
endif;
使用该格式，让我知道你是如何进行的：）
