{$taxonomy}_edit_form_fields不工作

Question

在我的插件文件中，我试图将内容添加到编辑自定义post类型的自定义分类的屏幕上。不幸的是什么都没有出现..。

<?
// A callback function to add a custom field to our taxonomy  
function my_custom_fields() {  
?>
<tr class="form-field">  
    <td>  
        hello 
    </td>  
</tr>  
<?
}  

// Add the fields to the taxonomy, using our callback function  
add_action( 'tha-seminar-category_edit_form_fields', 'my_custom_fields', 10, 2 );  
?>

我就是这样注册分类法的：

register_taxonomy('tha-seminar-category', 'tha_seminars',
array("hierarchical" => true,
"label" => "Tha Seminar Categories",
'update_count_callback' => '_update_post_term_count',
'query_var' => true,
'public' => true,
'show_ui' => true,
'show_admin_column' => true,
'show_tagcloud' => true,
'_builtin' => false,
'show_in_nav_menus' => true,
'show_in_rest' => true,
'show_in_quick_edit' => true,
'capabilities' => array(
    'manage_terms' => 'edit_tha_seminars',
    'edit_terms' => 'edit_tha_seminars',
    'delete_terms' => 'edit_tha_seminars',
    'assign_terms' => 'edit_tha_seminars'
    )
)
);

我希望在屏幕上看到“你好”

谢谢你帮忙！

使用tha-seminar-category_add_form_fields操作在新类别页面上显示。tha-seminar-category_edit_form_fields用于类别的编辑页面。
