wordpress主题分类自定义添加关键词

在当前主题的functions.php文件中添加以下代码：

<?phpglobal $texonomy_slug_keywords;$texonomy_slug_keywords='category';add_action($texonomy_slug_keywords.'_add_form_fields','categorykeywords');function categorykeywords($taxonomy){ ?><div><label for="tag-keywords">分类关键词</label><input type="text" name="tag-keywords" id="tag-keywords" value="" /><br /><span>请在此输入分类关键词。</span></div><?php }add_action($texonomy_slug_keywords.'_edit_form_fields','categorykeywordsedit');function categorykeywordsedit($taxonomy){ ?><tr ><th scope="row" valign="top"><label for="tag-keywords">关键词</label></th><td><input type="text" name="tag-keywords" id="tag-keywords" value="<?php echo get_option('_category_keywords'.$taxonomy->term_id); ?>" /><br /><span >请在此输入分类关键词。</span></td></tr> <?php }add_action('edit_term','categorykeywordssave');add_action('create_term','categorykeywordssave');function categorykeywordssave($term_id){if(isset($_POST['tag-keywords'])){if(isset($_POST['tag-keywords']))update_option('_category_keywords'.$term_id,$_POST['tag-keywords'] );}}?>1617181920212223242526<?phpglobal $texonomy_slug_keywords;$texonomy_slug_keywords='category';add_action($texonomy_slug_keywords.'_add_form_fields','categorykeywords');function categorykeywords($taxonomy){ ?><div><label for="tag-keywords">分类关键词</label><input type="text" name="tag-keywords" id="tag-keywords" value="" /><br /><span>请在此输入分类关键词。</span></div><?php }add_action($texonomy_slug_keywords.'_edit_form_fields','categorykeywordsedit');function categorykeywordsedit($taxonomy){ ?><tr ><th scope="row" valign="top"><label for="tag-keywords">关键词</label></th><td><input type="text" name="tag-keywords" id="tag-keywords" value="<?php echo get_option('_category_keywords'.$taxonomy->term_id); ?>" /><br /><span >请在此输入分类关键词。</span></td></tr><?php}add_action('edit_term','categorykeywordssave');add_action('create_term','categorykeywordssave');function categorykeywordssave($term_id){if(isset($_POST['tag-keywords'])){if(isset($_POST['tag-keywords']))update_option('_category_keywords'.$term_id,$_POST['tag-keywords'] );}}?>

在header.php文件中添加该字段内容作为分类keywords：

<?phpif(is_category()){$category_info = get_the_category();$category_id = $category_info[0]->cat_ID;$cat_keywords = get_option('_category_keywords'.$category_id);?><meta name="keywords" content="<?php echo $cat_keywords;?>"/><?php } ?>12345678<?phpif(is_category()){$category_info = get_the_category();$category_id = $category_info[0]->cat_ID;$cat_keywords = get_option('_category_keywords'.$category_id);?><meta name="keywords" content="<?php echo $cat_keywords;?>"/><?php } ?>
