wordpress 为自定义文章新增Tag标签

        我们新增了一个自定义文章navsues，一个网址导航分类，我们要对其增加TAG标签支持，使用下面的代码就可以了。

add_action( 'init', 'create_tag_taxonomies', 0 );
//create two taxonomies, genres and tags for the post type "tag"
function create_tag_taxonomies() 
{
  // Add new taxonomy, NOT hierarchical (like tags)
  $labels = array(
    'name' => _x( '网址标签', '网址标签' ),
    'singular_name' => _x( 'Tag', '网址标签' ),
    'search_items' =>  __( '搜索标签' ),
    'popular_items' => __( '热门标签' ),
    'all_items' => __( '所有标签' ),
    'parent_item' => null,
    'parent_item_colon' => null,
    'edit_item' => __( '编辑标签' ), 
    'update_item' => __( '更新标签' ),
    'add_new_item' => __( '新增一个标签' ),
    'new_item_name' => __( '新标签名称' ),
    'separate_items_with_commas' => __( '用逗号隔开标签' ),
    'add_or_remove_items' => __( '新增或删除标签' ),
    'choose_from_most_used' => __( '从最常用的标签中选择' ),
    'menu_name' => __( '标签' ),
  ); 
  register_taxonomy('tag','navsues',array(
    'hierarchical' => false,
    'labels' => $labels,
    'show_ui' => true,
    'update_count_callback' => '_update_post_term_count',
    'query_var' => true,
    'rewrite' => array( 'slug' => 'tag' ),
  ));
}

        配合之前新增的自定义文章和分类，就成了下面的。

// 注册自定义文章形式--网址导航
add_action('init', 'navsues');
function navsues()
{
    $labels = array(
        'name' => 'ues网址导航',
        'singular_name' => 'navsuess',
        'add_new' => '添加网址',
        'add_new_item' => '添加网址',
        'edit_item' => '编辑网址',
        'new_item' => '新网址',
        'all_items' => __('所有网址'),
        'view_item' => '查看网址',
        'search_items' => '搜索网址',
        'not_found' =>  '没有找到有关网址',
        'not_found_in_trash' => '回收站里面没有相关网址',
        'parent_item_colon' => '',
        'menu_name' => '网址导航'
    );
    $args = array(
        'labels' => $labels,
        'description'=> '自定义的网址类型',
        'public' => true,
        'publicly_queryable' => true,
        'show_ui' => true,
        'show_in_menu' => true,
        'query_var' => true,
        'rewrite' => true,
        'capability_type' => 'post',
        'has_archive' => true,
        'hierarchical' => true,
        'menu_position' => 6,
        'menu_icon' => 'dashicons-admin-links',
        'taxonomies'=> array('navsues_tag'),
        'supports' => array('title','editor','author','thumbnail','excerpt')
    );
    register_post_type('navsues',$args);
    $labels = array(
        'name' => '网址分类',
        'singular_name' => '网址分类',
        'search_items' =>  '搜索网址' ,
        'all_items' => '所有网址' ,
        'parent_item' => null,
        'parent_item_colon' => null,
        'edit_item' => '编辑网址' ,
        'update_item' => '更新网址' ,
        'add_new_item' => '添加网址分类' ,
        'new_item_name' => '新网址',
        'separate_items_with_commas' => '按逗号分开' ,
        'add_or_remove_items' => '添加或删除',
        'choose_from_most_used' => '从经常使用的类型中选择',
        'menu_name' => '网址分类',
    );
    register_taxonomy(
        'navsuess',
        array('navsues'),
        array(
            'hierarchical' => true,
            'labels' => $labels,
            'show_ui' => true,
            'query_var' => true,
        )
    );
}
add_action( 'init', 'create_tag_taxonomies', 0 );
//create two taxonomies, genres and tags for the post type "tag"
function create_tag_taxonomies() 
{
  // Add new taxonomy, NOT hierarchical (like tags)
  $labels = array(
    'name' => _x( '网址标签', '网址标签' ),
    'singular_name' => _x( 'Tag', '网址标签' ),
    'search_items' =>  __( '搜索标签' ),
    'popular_items' => __( '热门标签' ),
    'all_items' => __( '所有标签' ),
    'parent_item' => null,
    'parent_item_colon' => null,
    'edit_item' => __( '编辑标签' ), 
    'update_item' => __( '更新标签' ),
    'add_new_item' => __( '新增一个标签' ),
    'new_item_name' => __( '新标签名称' ),
    'separate_items_with_commas' => __( '用逗号隔开标签' ),
    'add_or_remove_items' => __( '新增或删除标签' ),
    'choose_from_most_used' => __( '从最常用的标签中选择' ),
    'menu_name' => __( '标签' ),
  ); 
  register_taxonomy('tag','navsues',array(
    'hierarchical' => false,
    'labels' => $labels,
    'show_ui' => true,
    'update_count_callback' => '_update_post_term_count',
    'query_var' => true,
    'rewrite' => array( 'slug' => 'tag' ),
  ));
}

        看一下成果，还是比较可以的。
