wordpress获得自定义帖子类型的分类列表
问题描述:
我对我的wordpress网站使用“视频”主题。在这个主题中,定义了视频文章类型和“视频类别”分类。这里是分类的注册码:wordpress获得自定义帖子类型的分类列表
add_action("init", "custom_posttype_menu_wp_admin1");
function custom_posttype_menu_wp_admin1()
{
register_post_type('videos',
array('label' => __('Videos','templatic'),
'labels' => array( 'name' => __('Video','templatic'),
'singular_name' => __('Video','templatic'),
'add_new' => __('Add Video','templatic'),
'add_new_item'=> __('Add New Video','templatic'),
'edit' => __('Edit','templatic'),
'edit_item'=> __('Edit Video','templatic'),
'new_item' => __('New Video','templatic'),
'view_item' => __('View Video','templatic'),
'search_items' => __('Search Videos','templatic'),
'not_found' => __('No Videos found','templatic'),
'not_found_in_trash'=> __('No Videos found in trash','templatic')
),
'public' => true,
'can_export' => true,
'show_ui' => true, // UI in admin panel
'_builtin' => false, // It's a custom post type, not built in
'_edit_link' => 'post.php?post=%d',
'capability_type' => 'post',
'menu_icon' => get_bloginfo('template_url').'/images/favicon.ico',
'hierarchical' => false,
'rewrite' => array("slug" => "videos"), // Permalinks
'query_var' => "videos", // This goes to the WP_Query schema
'supports' => array( 'title',
'author',
'excerpt',
'thumbnail',
'comments',
'editor',
'trackbacks',
'custom-fields',
'revisions') ,
'show_in_nav_menus' => true ,
'taxonomies' => array('videoscategory','videostags')
)
);
// Register custom taxonomy
register_taxonomy( "videoscategory",
array( "videos" ),
array ("hierarchical"=> true,
"label"=> "Category",
'labels'=> array( 'name' => __('Category','templatic'),
'singular_name'=> __('Category','templatic'),
'search_items'=> __('Search Category','templatic'),
'popular_items' => __('Popular Category','templatic'),
'all_items'=> __('All Category','templatic'),
'parent_item' => __('Parent Category','templatic'),
'parent_item_colon' => __('Parent Category:','templatic'),
'edit_item' => __('Edit Category','templatic'),
'update_item'=> __('Update Category','templatic'),
'add_new_item'=> __('Add New Category','templatic'),
'new_item_name'=> __('New Make Category','templatic')),
'public'=> true,
'show_ui' => true,
'query_var'=> true,
"rewrite" => true
)
);
}
我在视频分类分类下添加了一些类别。现在我想要获取属于videoscategory的所有类别。我GOOGLE了一整天,我用
$tax_terms =get_terms('videoscategory');
但得到空阵列。有谁知道这是什么问题?谢谢。

下面是使用此代码,你一定找到你的解决方案
$cat_args = array(
'orderby' => 'term_id',
'order' => 'ASC',
'hide_empty' => true,
);
$terms = get_terms('videoscategory', $cat_args);
foreach($terms as $taxonomy){
$term_slug = $taxonomy->slug;
$tax_post_args = array(
'post_type' => 'videos',
'posts_per_page' => 999,
'order' => 'ASC',
'tax_query' => array(
array(
'taxonomy' => 'videoscategory',
'field' => 'slug',
'terms' => '$term_slug'
)
)
);
$tax_post_qry = new WP_Query($tax_post_args);
if($tax_post_qry->have_posts()) :
while($tax_post_qry->have_posts()) :
$tax_post_qry->the_post();
the_title();
endwhile;
else :
echo "No posts";
endif;
} //end foreach loop

在这里完成的是给你一个例子,我用了一个常见问题职位类型:
get_header();
if(have_posts()) {
$args = array (
'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => true,
);
$terms = get_terms('faq_levels', $args);
foreach ($terms as $term) {
echo $term->slug;
$post_args = array (
'post_type' => 'faq',
'faq_levels' => $term->name,
);
$query = new WP_Query($post_args);
while ($query->have_posts()) {
$query->the_post(); ?>
和我创建的帖子类型是这样的:
function post_type_faqs() {
register_post_type('faq', array(
'label'=>'FAQ',
'menu_icon' => '',
'labels'=>array(
'name'=>_x('FAQs', 'post type general name'),
'singular_name'=>_x('FAQ', 'post type singular name'),
'add_new'=>_x('Add New', 'faq'),
'add_new_item'=>__('Add New FAQ'),
'edit_item'=>__('Edit FAQ'),
'new_item'=>__('New FAQ'),
'view_item'=>__('View FAQ'),
'search_items'=>__('Search FAQs'),
'not_found'=>__('No faqs found'),
'not_found_in_trash'=>__('No faqs found in Trash'),
'parent_item_colon'=>''),
'public'=>true,
'publicly_queryable'=>true,
'show_ui'=>true,
'query_var'=>true,
'rewrite'=>false,
'capability_type'=>'post',
'supports'=>array('title','thumbnail','post-formats'),
'taxonomies'=>array('post_tag','faq_category'),
'slug'=>'faq',
'hierarchical'=>false,
'menu_position'=>6,
'show_in_nav_menus'=> true,
'has_archive' => true,
'can_export' => true,
'register_meta_box_cb' => 'faq_add_meta_boxes'
));
}
add_action('init', 'post_type_faqs');
/**
* Create Subjects taxonomy
*/
function faq_category() {
$labels = array(
'name' => _x('Categories', 'Taxonomy General Name', 'dc'),
'singular_name' => _x('Category', 'Taxonomy Singular Name', 'dc'),
'menu_name' => __('Categories', 'dc'),
'all_items' => __('All Categories', 'dc'),
'parent_item' => __('Parent Category', 'dc'),
'parent_item_colon' => __('Parent Category:', 'dc'),
'new_item_name' => __('New Category', 'dc'),
'add_new_item' => __('Add New Category', 'dc'),
'edit_item' => __('Edit Category', 'dc'),
'update_item' => __('Update Category', 'dc'),
'separate_items_with_commas' => __('Separate categories with commas', 'dc'),
'search_items' => __('Search Categories', 'dc'),
'add_or_remove_items' => __('Add or remove categories', 'dc'),
'choose_from_most_used' => __('Choose from the most used categories', 'dc'),
'not_found' => __('Not Found', 'dc'),
);
$args = array(
'labels' => $labels,
'hierarchical' => true,
'public' => true,
'show_ui' => true,
'show_admin_column' => true,
'show_in_nav_menus' => true,
'show_tagcloud' => true,
'sort_column' => 'menu_order',
);
register_taxonomy('faq_category', array('faq'), $args);
}
add_action('init', 'faq_category', 0);
易于使用得到所有自定义后类型类别:HTTP://wp.m E/p4esuX-3K – 2014-12-31 06:53:16
