有向类别编辑器添加自定义域的示例吗？

我想我很快就要搞定这个问题了：）

我正在尝试向类别编辑器添加一组自定义字段。由于我没有处理post-meta，我相信我会将自定义类别字段值写入wp\\u term\\u分类表，而不是wp\\u options表。这是正确的吗？

如果有任何关于如何做到这一点的示例，请共享一个链接或一段代码。我不知道如何捕获和保存自定义类别字段。

这是我的密码。。。

//add the hook to place the form on the category editor screen
add_action(\'edit_category_form\',\'ce4_category_admin\');

//Adds the custom title box to the category editor
function ce4_category_admin($category){
    echo "category: ".$category->term_id; //great, I got a reference to the term_id, now I need to get/set my custom fields with this key
    ?>
<table class="form-table">
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4-categoryTitle">Full Category Title</label></th>
