使用自定义分类术语标识自定义字段

Question

我已经为我的布道自定义帖子类型创建了一个自定义的单个sermons.php模板文件,并希望在此帖子中包含布道说话者的讲道图像自定义字段.

自定义分类ID:sermon_speaker自定义字段ID:sermon_speaker_image

我已经能够获得分类学术语ID以在页面上显示为数字,使用:

<?php

$terms = wp_get_post_terms($post->ID, "sermon_speaker");
foreach ($terms as $termid) {  
echo $termid->term_id;
} 

?>

我正在尝试弄清楚如何在我目前拥有的代码中使用此术语ID.$ term_id,以便将术语ID添加到背景图像URL的末尾.

<div class="sermon-speaker-image" style="background-image: url('<?php the_field( 'sermon_speaker_image', 'sermon_speaker_' . $term_id ); ?>');"></div>

更新:以下代码是基于以下答案的工作解决方案:

<?php
global $post;

// load all 'sermon_speaker' terms for the post
$terms = get_the_terms($post->ID, 'sermon_speaker');

// we will use the first term to load ACF data from
if( !empty($terms) )
{
    $term = array_pop($terms);

    $custom_field = get_field('sermon_speaker_image', $term );

}
?>
<div class="sermon-speaker-image" style="background-image: url('<?php echo $custom_field; ?>');"></div>

尝试这个代码，这应该适合你

 global $post;

    // load all 'sermon_speaker' terms for the post

    $terms = get_the_terms($post->ID, 'sermon_speaker');

    // we will use the first term to load ACF data from
    if( !empty($terms) )
    {
        $term = array_pop($terms);

        $custom_field = get_field('sermon_speaker_image', $term );

        // do something with $custom_field
        //i.e. echo $custom_field;
        //i.e. echo "<img src='$custom_field'/>";
       ?>
<div class="sermon-speaker-image" style="background-image: url('<?php echo $custom_field; ?>');"></div>
<?
    }
