自定义帖子类型的 WordPress 自定义字段

过去有几个人出现过这个问题，但他们的问题的解决方案对我来说不起作用，我已经尝试了很多！

在 WordPress 中，我创建了 3 种自定义帖子类型。 1 代表“视频”、“新闻”和“音乐”，每个内容都发布到自己的页面。我想添加自定义字段，这样我就可以为音乐帖子添加“艺术家”、“发行年份”、“特色”和“关于专辑”。

我已经安装了高级自定义字段，并且可以向每个字段添加自定义字段，因此当用户单击“添加新”时，这些字段是可见的。但我遇到的问题是，当我访问该页面时，这些字段的输出没有显示在网站上。

我使用以下内容从 single.php 文件创建了 news.php、music.php 和videos.php：

    <?php
/**
 * Template Name: music Page
 *
 * Selectable from a dropdown menu on the edit page screen.
 */

get_header(); ?>

    <div id="primary" class="site-content">
        <div id="content" role="main">
<?php query_posts( 'post_type=music'); ?>
<?php the_meta(); ?> 
            <?php while ( have_posts() ) : the_post(); ?>
                <?php get_template_part( 'content',  get_post_format() ); ?>
                <?php comments_template( '', true ); ?>
            <?php endwhile; // end of the loop. ?>

        </div><!-- #content -->
    </div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

在functions.php 中我有以下内容：

/*---------music Custom Post Types---------------------------------*/

function my_custom_post_music() {
    $labels = array(
        'name'               => _x( 'music', 'post type general name' ),
        'singular_name'      => _x( 'music', 'post type singular name' ),

    );
    register_post_type( 'music', $args );   
}
add_action( 'init', 'my_custom_post_music' );



function my_taxonomies_music() {

        'singular_name'     => _x( 'music Category', 'taxonomy singular name' ),

    );
    $args = array(
        'labels' => $labels,
        'hierarchical' => true,
    );
    register_taxonomy( 'music_category', 'music', $args );
}
add_action( 'init', 'my_taxonomies_music', 0 );


/*---------news Custom Post Types---------------------------------*/

function my_custom_post_news() {
    $labels = array(
        'name'               => _x( 'news', 'post type general name' ),
        'singular_name'      => _x( 'news', 'post type singular name' ),
        'add_new'            => _x( 'Add New', 'book' ),
        'add_new_item'       => __( 'Add New news' ),
        'edit_item'          => __( 'Edit news' ),
        'new_item'           => __( 'New news' ),
        'all_items'          => __( 'All news' ),
        'view_item'          => __( 'View news' ),
        'search_items'       => __( 'Search news' ),
        'not_found'          => __( 'No news found' ),
        'not_found_in_trash' => __( 'No news found in the Trash' ), 
        'parent_item_colon'  => '',
        'menu_name'          => 'News'
    );
    $args = array(
        'labels'        => $labels,
        'description'   => 'Holds our news and news specific data',
        'public'        => true,
        'menu_position' => 10,
        'supports'      => array( 'title', 'editor', 'thumbnail', 'excerpt', 'comments' ),
        'has_archive'   => true,
    );
    register_post_type( 'news', $args );    
}
add_action( 'init', 'my_custom_post_news' );

有谁知道我缺少什么才能使其正常工作或我需要做什么。

任何建议都非常感激。

要在循环中显示自定义字段的值，您可以使用以下代码片段：

<?php query_posts( 'post_type=music'); ?>
  <?php while ( have_posts() ) : the_post(); ?>
   <?php get_template_part( 'content',  get_post_format() ); ?>

   <?php $what_name_you_want=get_post_meta($post->ID,'Your Custom Field Name',true); ?>

    <?php echo $what_name_you_want; ?>// This call the value of custom field


                <?php comments_template( '', true ); ?>
            <?php endwhile; // end of the loop. ?>

告诉我是否有效！
