ACF 转发器字段未呈现行

Question

我有这个网站，我正在为客户工作。 我跳进了这个项目，我必须在模板文件上为特定页面创建手风琴。 我刚刚开始深入了解 PHP 所以我在这篇文章中在线找到了解决方案https://wpbeaches.com/create-an-acf-repeater-accordion-in-wordpress/现在，我的问题是：我创建了转发器字段with two subfields https://prnt.sc/xfg3lv and I choose that it only shows on this page template https://prnt.sc/xfg6lw Then I created the fields on the actual page with that template https://prnt. sc/xfgdhp并将文章中的那段代码插入到模板文件中。 当然，我用我的字段名称修改了名称。 问题是在前面它没有显示行，即使它们存在，只是跳到 else 语句。 我将粘贴该模板页面的完整代码，因此如果有人可以提供帮助，那就太好了。 在这个问题上，我已经绞尽脑汁两天了。

代码（我标记了我的代码开始和结束的位置）：

<?php
/**

      $post_slug = $post->post_name;
      $grandParent_title=get_page(get_ancestors($post->ID,'page')[0] )->post_title;
      $grandParent_Image=wp_get_attachment_url( get_post_thumbnail_id(get_ancestors($post->ID,'page')[0] )) ;
      get_header();



global $wp;

$current_slug = add_query_arg( array(), $wp->request );
$url_slug=explode('/', $current_slug);

$uri_string=$url_slug[1];
$_SESSION['current_url']=$uri_string;


function find_string_in_array ($arr, $string) {

    return array_filter($arr, function($value) use ($string) {
        return strpos($value, $string) !== false;
    });

}

尝试将您的内容包装成：

<?php while (have_posts()) : the_post(); ?>

// all your content related to the post including repeater code.

<?php endwhile; // End of the loop.?>

这样中继器将位于您当前帖子/页面的 scope 中。 或者，您可以在转发器 function 中将帖子 ID 指示为参数。
