我想知道是否有人能帮我。我有一个自定义的post类型，称为associations。我使用高级自定义字段将一些自定义字段与post类型关联，其中2个是post对象字段。这允许我显示来自其他帖子类型的帖子内容。我想在单个关联中显示此信息。php，我遵循了ACF网站上的文档，但我遇到了一个问题，即post对象available\\u products中的图像未显示此字段标记为“product\\u icon”，post对象字段如下（coverage\\u highlights，available\\u products）请参阅下面的代码：
<?php
$post_objects = get_field(\'coverage_highlights\');
if( $post_objects ): ?>
<div class="association-products-side-bar">
<h3 class="text-center">Coverage Highlights</h3>
<ul>
<?php foreach( $post_objects as $post): // variable must be called $post (IMPORTANT) ?>
<?php setup_postdata($post); ?>
<li>
<a href="<?php the_permalink(); ?>">
<?php the_title(); ?>
</a>
</li>
<?php endforeach; ?>
</ul>
</div>
<?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif;
/*
* Loop through post objects (assuming this is a multi-select field) ( don\'t setup postdata )
* Using this method, the $post object is never changed so all functions need a seccond parameter of the post ID in question.
*/
$post_objects = get_field(\'available_products\');
if( $post_objects ): ?>
<div class="association-products-side-bar">
<h3 class="text-center">Available Products</h3>
<ul>
<?php foreach( $post_objects as $post_object): ?>
<li>
<?php
$image = get_field(\'product_icon\');
if( !empty($image) ): ?>
<img src="<?php echo $image[\'url\']; ?>" alt="<?php echo $image[\'alt\']; ?>" />
<?php endif; ?>
<?php endforeach; ?>
<a href="<?php echo get_permalink($post_object->ID); ?>"><?php echo get_the_title($post_object->ID); ?></a>
</li>
<?php endforeach; ?>
</ul>
</div>
<?php endif;
?>
