从WordPress高级自定义字段数组获取正确的图像url?,wordpress,wordpress-theming,advanced-custom-fields,Wordpress,Wordpress Theming,Advanced Custom Fields,Wordpress新手 $article_data = get_field('article_item'); foreach ($article_data as $key => $item) { $footerImg = (!empty($item['bottom_image'])) ? $item['bottom_image'] : NULL; $url = implode( ', ', $footerImg ); echo $url; } 其结果如下

Wordpress新手

$article_data = get_field('article_item');
  foreach ($article_data as $key => $item) {
    $footerImg = (!empty($item['bottom_image'])) ? $item['bottom_image'] : NULL;
    $url = implode( ', ', $footerImg );
    echo $url;

  }
其结果如下:

2345, 
67899, 
boston_skyline, 
boston_skyline.jpg, 
http://localhost:8000/bostontheme/images/2018/08/boston_skyline.jpg,

如何抓取其中的图像字符串,以便执行以下操作:

<img src="<?php echo $url ?>" />
我得到这个输出:

Array ( 
[bottom_image] => Array ( 
[ID] => 67899 
[id] => 67899 
[title] => boston_skyline 
[filename] => boston_skyline.jpg 
[url] => http://localhost:8000/bostontheme/images/2018/08/boston_skyline.jpg

您只需要
$item[“底部图像”][“url”]

添加
打印($item)并用输出更新您的问题。顺便说一句,这不是一个“WordPress自定义字段数组”,它是一个高级自定义字段数组。嗨@PeterHvD我更新了这篇文章以反映你的建议。对印刷品的输出有什么想法吗?
Array ( 
[bottom_image] => Array ( 
[ID] => 67899 
[id] => 67899 
[title] => boston_skyline 
[filename] => boston_skyline.jpg
