<?php

add_action($texonomy_slug_tags.’_add_form_fields’,’categorykeywords’);
function categorykeywords($taxonomy){ ?>
<div>
<label for=”tag-keywords”>分类关键词</label>
<input type=”text” name=”tag-keywords” id=”tag-keywords” value=”” /><br />

<th scope=”row” valign=”top”><label for=”tag-keywords”>小说标签</label></th>
<td><input type=”text” name=”tag-keywords” id=”tag-keywords” value=”<?php echo get_option(‘_category_keywords’.$taxonomy->term_id); ?>” /><br /></td>
