我查看过有关向CPT列添加自定义分类的几篇帖子;除了实际显示所述分类法(出版物)之外,我能够使一切正常。这是我的CPT代码:
add_action( 'init', 'pb_custom_post_type' );
function pb_custom_post_type() {
$labels = array(
'name' => _x( 'Press', 'post type general name' ),
'singular_name' => _x( 'Press', 'post type singular name' ),
'add_new' => _x( 'Add New', 'review' ),
'add_new_item' => __( 'Add New Press' ),
'edit_item' => __( 'Edit Press' ),
'new_item' => __( 'New Press' ),
'all_items' => __( 'All Press' ),
'view_item' => __( 'View Press' ),
'search_items' => __( 'Search Press' ),
'not_found' => __( 'No press found' ),
'not_found_in_trash' => __( 'No press found in the Trash' ),
'parent_item_colon' => '',
'menu_name' => 'Press'
);
$args = array(
'labels' => $labels,
'description' => 'Press information',
'public' => true,
'menu_position' => 20,
'supports' => array( 'title', 'editor', 'thumbnail' ),
'has_archive' => true,
);
register_post_type( 'press', $args );
}
add_filter( 'manage_edit-press_columns', 'my_edit_press_columns' ) ;
function my_edit_press_columns( $columns ) {
$columns = array(
'cb' => '<input type="checkbox" />',
'title' => __( 'Title' ),
'publication' => __( 'Publication' ),
'date' => __( 'Date' )
);
return $columns;
}
自定义分类
add_action( 'init', 'create_my_taxonomies', 0 );
function create_my_taxonomies() {
register_taxonomy( 'publication', 'press', array( 'hierarchical' => false, 'label' => 'Publications', 'query_var' => false, 'rewrite' => true ) );
}
现在我已经看到了两种不同的选择,要么尝试在分类法参数中添加show_ui / show_admin_column,要么在switch语句中使用另一个函数。我已经在下面尝试了,是否有一些我不知道的重要事项?
1
add_action( 'init', 'create_my_taxonomies', 0 );
function create_my_taxonomies() {
$args = array (
'show_ui' => true,
'show_admin_column' => true,
);
register_taxonomy( 'publication', 'press', array( 'hierarchical' => false, 'label' => 'Publications', 'query_var' => false, 'rewrite' => true ), $args );
}
2
function custom_columns( $column, $post_id ) {
switch ( $column ) {
case "publication":
echo get_post_meta( $post_id, 'publication', true);
break;
}
}
add_action( "manage_posts_custom_column", "custom_columns", 10, 2 );
答案 0 :(得分:1)
删除自定义列函数,并将'show_admin_column' => true
添加到register_taxonomy
的实际args数组中:
register_taxonomy( 'publication', 'press', array( 'show_admin_column' => true, 'hierarchical' => false, 'label' => 'Publications', 'query_var' => false, 'rewrite' => true ) );
修改:您可能还想将'taxonomies' => array( 'publication' )
添加到register_post_type
args。
