我在WordPress中使用ACF。

我有一个名为Projects. 在那里，用户可以选择通过 ACF 转发器字段上传2 个特色图像。

现在，在主页上，我为用户提供了从Projects post type中选择8 个 Post Object's的选项。

我需要能够遍历这个主页转发器字段，并从每个“项目”帖子对象中提取特色图像和项目标题。

ACF 最近贬低了repeater_field我认为它让我失望的功能。

但是，到目前为止，这是我一直在尝试使用的内容：

<!-- check for repeater field -->
<?php if(get_field('featured-projects')): ?>

    <?php while(has_sub_field('featured-projects')): ?>

        <!-- get project post objects -->
        <?php $projects = get_sub_field('project'); ?>

        <!-- without the loop below, this echo's all 8 projects ID's -->
        <?php echo($projects->ID); ?><br />

        <!-- when added, only pulls the first project. And limits the echo above to the first ID -->
        <?php $loop = new WP_Query( array( 
            'post_type' => 'projects',
            'p' => $projects->ID
        ) ); ?>

        <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>


        <?php endwhile; ?>


    <?php endwhile; ?>

<?php endif; ?>

我试图评论代码，但如果有什么不合理的地方，请告诉我。

这就是我的做法，尽管我意识到它与你的方法不同。我在代码注释中包含了解释：

<?php $featured_projects = get_field('featured-projects'); //Set $featured_projects to equal the array of projects from the home page repeater. ?>

<!-- check for repeater field -->
<?php if($featured_projects): ?>

      <?php foreach($featured_projects as $featured_project) : //Loop through each featured project ?>

          <?php  $project_id = $featured_project['project']->ID; //Get the id for the current featured project ?>

          <?php $project_title = get_the_title($project_id); //set $title to be the title of the project ?> 
          <?php project_featured_images = get_field('name-of-featured-repeater-field-here', $project_id); //get the repeater field of the featured images from the project post ?>



          <h1 class='title'><?php echo $project_title; //print the title ?></h1>

          <?php if($project_featured_images[0]): //check if you have a 1st image (size large) ?> 
              <img class='featured-image-one' src="<?php echo $project_featured_images[0]['name-of-the-featured-image-sub-field-here']['sizes']['large']; //print the url to the 1st image; ?>"/>
          <?php endif; ?>

          <?php if($project_featured_images[1]): //check if you have a 2nd image ?> 
              <img class='featured-image-two' src="<?php echo $project_featured_images[1]['name-of-the-featured-image-sub-field-here']['sizes']['large']; //print the url to the 2nd image (size large); ?>"/>
          <?php endif; ?>

      <?php endforeach; ?>

<?php endif; ?>

确保填写项目特色图像转发器字段的名称，以及该转发器中图像子字段的名称。这显然是一个比 API 版本更标准的基于 PHP 的解决方案。我通常根据 Elliot Candon（ACF 开发人员）的建议使用此方法。

您还可以通过将“大”更改为另一个标准尺寸或添加自定义尺寸来获得特色图像的不同图像尺寸。
