Question

我为自定义帖子类型创建了自定义字段。当我检索主题模板中的值图像值返回22。如何获取图片网址。？

<?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$ project

时

WP_Post Object
(
    [ID] => 35
    [post_author] => 1
    [post_date] => 2017-04-07 05:50:29
    [post_date_gmt] => 2017-04-07 05:50:29
    [post_content] => Tekzenit
    [post_title] => Tekzenit
    [post_excerpt] => 
    [post_status] => publish
    [comment_status] => closed
    [ping_status] => closed
    [post_password] => 
    [post_name] => tekzenit
    [to_ping] => 
    [pinged] => 
    [post_modified] => 2017-04-07 06:12:54
    [post_modified_gmt] => 2017-04-07 06:12:54
    [post_content_filtered] => 
    [post_parent] => 0
    [guid] => http://10.180.82.8/fareed/?post_type=projects&p=35
    [menu_order] => 0
    [post_type] => projects
    [post_mime_type] => 
    [comment_count] => 0
    [filter] => raw
)

Answer 1

如果您使用高级自定义字段或自己编写代码，有些信息会对您创建自定义字段的方式有所帮助。

但是如果您有图像ID，那么您可以使用：

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

Answer 2

$project->project_image返回id

您可以使用wp_get_attachment_image_url功能获取图片网址

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

在主题中搜索自定义字段的图像URL
