我有一个“活动”自定义帖子类型，其中包含特定原因的详细信息（一段左右）。
同一帖子上有一张用于支付处理的“捐赠”表单（用于发布用户详细信息、捐赠金额等），该表单从前端更新捐赠自定义帖子类型fmeta。
然而，要更新捐款贴子元，它需要获得捐款贴子类型的global$post\\u id，还需要选择活动贴子类型。
以下是表格代码：
<?php
if (isset( $_POST[‘cpt_nonce_field’] ) && wp_verify_nonce( $_POST[‘cpt_nonce_field’],‘cpt_nonce_action’ ) && ($post_id) )
{
update_post_meta($post_id, donations_metabox_donation-id, $_POST[\'donation_id\']);
update_post_meta($post_id, donations_metabox_cause-id, $_POST[\'cause_id\']);
update_post_meta($post_id, cause-title, $_POST[\'donation_for\']);
update_post_meta($post_id, donations_metabox_donation-currency, $_POST[\'donation_currency\']);
update_post_meta($post_id, donations_metabox_cause-amount, $_POST[\'cause_amount\']);
update_post_meta($post_id, donations_metabox_full-name, $_POST[\'full_name\']);
update_post_meta($post_id, donations_metabox_email, $_POST[\'email\']);
}
?>
<?php get_header(); ?>
<!-- main_wrapper -->
<div id="main_wrapper">
<div class="content-wrapper">
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<!-- tbl-layout -->
<div class="tbl-layout">
<div class="col left">
<h1><?php the_title(); ?></h1>
<?php $url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) ); ?>
<p><?php the_content(); ?></p>
</div>
<?php endwhile; ?>
<?php endif; ?>
<div class="col right">
<h2>Your Donation</h2>
<!-- donation start -->
<form method="post" action="">

<select name="donation_for" id="donation_for" class="dd">
<?php
$args = array( \'post_type\'=>\'cause\',\'posts_per_page\' => -1,);
$myposts = get_posts( $args );
foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
?>
<option value="<?php the_title(); ?>"><?php the_title(); ?></option>
<?php endforeach; ?>
</select>
<br>
<label for="donation_currency">Currency</label><br>
<select name="donation_currency[]" id="donation_currency" class="dd">

<input type="hidden" name="donation_id" id="donation_id" value="<?php printf(uniqid()); ?>">
<input type="hidden" name="cause_id" id="cause_id" value="<?php the_ID();?>">
<?php wp_reset_postdata(); ?>
<?php wp_nonce_field( ‘cpt_nonce_action’, ‘cpt_nonce_field’ ); ?>
</form>
</div>
<!-- donation end -->

<!-- tbl-layout end -->

我将使用活动的id来建立两种帖子类型之间的关系，因此我不会使用诸如post 2 post或Pods之类的插件（除非根据我的问题建议有必要）
第一次海报，谢谢您的时间。
