我已经坚持了一个月左右，现在已经没时间完成了！
基本上（请参阅下面的print_R）我有一个名为＆＃39; Penguin＆＃39;我在ACF创建的。我的网站的功能允许这些企鹅＆＃39;企鹅＆＃39;为了参加游泳比赛，我有另一种名为“赛事”的帖子类型。这是他们将要进入的事件。我有一个名为Fixture的帖子类型，它有一个名为＆＃39; event_selector＆＃39;的转发器。事件＆＃39; post type是一个重复的post对象，然后是一个名为＆＃39; standings＆＃39;的转发器字段。在那之内。在这个中继器领域内是企鹅＆＃39;企鹅＆＃39;邮寄对象。
当使用后端使用企鹅添加和更新事件时，它可以正常工作，但是当尝试使用update_field（）/ update_sub_field（）在前端进行更新时，没有任何反应！我不知道如何继续尝试解决这个问题。我添加了一个print_r的转发器字段和我想用来更新字段以添加更多企鹅的代码，我希望有人可以提供帮助！
<?php
$fixtureArgs = array(
'post_type' => 'fixture',
'post_id' => $fixtureID );
$fixtureLoop = new WP_Query($fixtureArgs);
if($fixtureLoop->have_posts()) :
while($fixtureLoop->have_posts()) : $fixtureLoop->the_post();
if(get_the_ID() == $fixtureID) :
$field_key = 'event_selector';
$post_id = $childID;
$value = get_field($field_key, $post_id);
$value[] = array(
'standings' => array(array('penguin' => $value))
);
update_field($field_key, $value, $post_id);
endif;
endwhile;
