在主题中回收自定义字段的图像URL

我为自定义帖子类型创建了自定义字段。当我检索返回值为22的主题模板图像值中的值。如何获取图像URL？在主题中回收自定义字段的图像URL

<?php 
    $args = array(
    'posts_per_page' => -1, 
    'post_type'  => 'projects', 
    'post_status'  => 'publish', 
    ); 
    $projects = get_posts($args); 

    foreach ($projects as $project) { 
     echo $project->project_title; // Title Text 
     echo $project->project_description; // Description Content 
     echo $project->project_image; // 22 

    } ?>

当我打印$项目

WP_Post Object 
(
    [ID] => 35 
    [post_author] => 1 
    [post_date] => 2017-04-07 05:50:29

你的问题不够清楚。你为自定义帖子类型创建了**自定义元域**（project_title，project_description，project_image）吗？你是否也获得了project_title和project_description的价值？ – Ninja

您是否记得将ACF设置为返回URL或对象？如果你没有设置它，它可能只是返回ID。 – Stender

$project->project_image返回ID

您可以将用户wp_get_attachment_image_url函数来获取图像URL

if($project->project_image){ 
    $imagePath = wp_get_attachment_image_url($project->project_image, '');                  
    echo imagePath 
}

一些更多的信息将是对像，如果你采用了先进的自定义字段或自己写的代码，你如何创建自定义字段帮助。

但如果你有图像ID，那么你可以使用：

$img_id = $project->project_image; 
$img_array = wp_get_attachment_image_src($img_id, 'full'); 
$img_url = $img_array[0]; 
echo $img_url;
