在单个自定义 post 类型中显示所选类别 (Wordpress)

Showing selected categories in a single of a custom post type (Wordpress)

我创建了一个名为成员的自定义 post 类型:

// Custom post types

function members_post_type()
{
    $args = array(
        'labels' => array(
            'name' => 'Members',
            'singular_name' => 'Member',
            'all_items' => 'All members'
        ),
        // 'hierarchical' => true,
        'public' => true,
        'has_archive' => true,
        'supports' => array('title', 'editor' , 'thumbnail'),
        'menu_icon' => 'dashicons-groups'
    );
    register_post_type('members', $args);
}

add_action('init', 'members_post_type');

function members_taxonomys()
{
    $args = array(
        'public' => true,
        'hierarchical' => true
    );
    register_taxonomy('Categories', array('members'), $args);
}

add_action('init', 'members_taxonomys');
并在单members.php 我制作了这段代码来调用我的类别:

<?php if(have_posts()):?>
<?php while(have_posts() ): ?>
    <?php 
        the_category(' ');
    ?>

由于某种原因,它没有用。欢迎提出更多问题或更多详情。

  1. 您好,首先您需要更改自定义分类法的名称并为其添加标签:
function members_taxonomys()
{
    $args = array(
        'label'                 => 'My categories', // Label
        'public' => true,
        //'show_admin_column'     => true,
        'hierarchical' => true
    );
    // Custom category 
    register_taxonomy('my_categories', array('members'), $args);
}

add_action('init', 'members_taxonomys');

  1. 创建您自己的 post 类型时,您需要删除重写规则:
function members_post_type()
{
    $args = array(
        'labels' => array(
            'name' => 'Members',
            'singular_name' => 'Member',
            'all_items' => 'All members'
        ),
        // 'hierarchical' => true,
        'public' => true,
        'query_var'           => true,
        'rewrite'             => true,
        'has_archive' => true,
        'supports' => array('title', 'editor' , 'thumbnail'),
        'menu_icon' => 'dashicons-groups'
    );
    register_post_type('members', $args);

    flush_rewrite_rules(false); // Remove rewrite rules 
}
  1. 创建新成员post并为其分配自定义分类法

  2. 然后你需要替换the_category();函数因为它适用于标准类别分类法,你需要使用get_the_terms函数

<?php if(have_posts()):?>
<?php while(have_posts() ): the_post(); ?>
    <?php 
       $categories = get_the_terms($post, 'my_categories');
       if(!empty($categories)) {
           ?><ul><?php
                foreach($categories as $cat) {
                    print "<li>$cat->name</li>";
                }
           ?></ul><?php           
       }        
    ?>
<?php endwhile; ?>
<?php endif;?>
