在創建wordpress自定義分類時顯示通知

Question

我正在嘗試爲自定義文章創建自定義分類。但是，當我試圖添加新的類別時，會顯示一條通知，例如「試圖獲取非對象屬性...的通知」。這是自定義代碼發佈

function newsbox_post() { 
    register_post_type('newsbox-post', 
    array(
     'label'    => __('Newsbox Post', 'text_domain'), 
     'labels' => array(
      'name' => __('Newsbox Posts'), 
      'singular_name' => __('Newsbox Post'), 
      'menu_name' => __(' Newsbox Post', 'text_domain'), 
      'parent_item_colon' => __('Parent Newsbox post:', 'text_domain'), 
      'all_items'   => __('All Newsbox post', 'text_domain'), 
      'view_item'   => __('View Newsbox post', 'text_domain'), 
      'add_new_item'  => __('Add New post', 'text_domain'), 
      'add_new'    => __('New post', 'text_domain'), 
      'edit_item'   => __('Edit post', 'text_domain'), 
      'update_item'   => __('Update post', 'text_domain'), 
      'search_items'  => __('Search post', 'text_domain'), 
      'not_found'   => __('No post found', 'text_domain'), 
      'not_found_in_trash' => __('No post found in Trash', 'text_domain') 
     ), 
     'public' => true, 
     'rewrite' => array('slug' => 'Newsbox-post'), 
     'description'   => __('Enter recent to your newsbox', 'text_domain'), 
     'supports'   => array('title', 'editor', 'page-attributes'), 
     'show_ui'    => true, 
     'show_in_menu'  => true, 
     'show_in_nav_menus' => false, 
     'show_in_admin_bar' => true, 
     'can_export'   => false, 
     'has_archive'   => false, 
     'exclude_from_search' => true, 
     'publicly_queryable' => true, 
     'capability_type'  => 'post' 
     ) 
); 
} 

add_action('init', 'newsbox_post'); 

這裏是自定義分類

add_action('init', 'newsbox_post_category_taxonomy', 0); 

function newsbox_post_category_taxonomy() { 
$labels = array(
'name' => _x('Categories', 'taxonomy general name'), 
'singular_name' => _x('Categories', 'taxonomy singular name'), 
'search_items' => __('Search Category'), 
'all_items' => __('All Categories'), 
'parent_item' => __('Parent Category'), 
'parent_item_colon' => __('Parent Category:'), 
'edit_item' => __('Edit Category'), 
'update_item' => __('Update Category'), 
'add_new_item' => __('Add New Category'), 
'new_item_name' => __('New Categories Name'), 
'menu_name' => __('Categories'), 
);  



    register_taxonomy('Categories',array('newsbox-post'), array(
    'hierarchical' => true, 
    'labels' => $labels, 
    'show_ui' => true, 
    'show_admin_column' => true, 
    'query_var' => true 

)); 

    } 

請告訴我解決方案的代碼。謝謝。

Answer 1

您的問題與語法有關。有兩個問題關閉後與您的代碼

• 在自定義分類名稱或自定義後類型名稱切勿使用大小寫混合。

• 切勿在自定義帖子類型名稱或自定義分類名稱中使用超文本（-）以及任何特殊字符。如果你有一個名稱分隔名稱/也就是說，只有使用下劃線（_）

Categories應該是categories你的分類名稱和newsbox-post應該newsbox_post爲您的自定義後類型名稱

編輯

正確地格式化您的代碼並進行相關更改。測試和工程

add_action('init', 'combined_registration'); 

function combined_registration() { 
    $labels = array(
     'name' => _x('Categories', 'taxonomy general name'), 
     'singular_name' => _x('Categories', 'taxonomy singular name'), 
     'search_items' => __('Search Category'), 
     'all_items' => __('All Categories'), 
     'parent_item' => __('Parent Category'), 
     'parent_item_colon' => __('Parent Category:'), 
     'edit_item' => __('Edit Category'), 
     'update_item' => __('Update Category'), 
     'add_new_item' => __('Add New Category'), 
     'new_item_name' => __('New Categories Name'), 
     'menu_name' => __('Categories'), 
    );  

    register_taxonomy('categories',array('newsbox_post'), array(
     'hierarchical' => true, 
     'labels' => $labels,
