列表頁原标題寫法：

<meta name="keywords" content="<yunu:config name='seo_keywords'>">
<meta name="description" content="<yunu:config name='seo_description'>">
<title>{$category.title}-<yunu:config name="site_title"></title>

上面(miàn)這(zhè)種(zhǒng)寫法在後(hòu)台欄目設置自定義标題時，是無法顯示的，優化寫法爲

列表頁

<title><if condition="strlen($category['seo_title']) neq 0">{$category.seo_title}<else/>{$category.title}-<yunu:config name="site_title"></if></title>
<meta name="keywords" content="<if condition="strlen($category['seo_keywords']) neq 0">{$category.seo_keywords}<else/>{$category.title}</if>">
<meta name="description" content="<if condition="strlen($category['seo_desc']) neq 0">{$category.seo_desc|str2sub=160, true}<else/>{$category.desc|str2sub=160, true}</if>">

這(zhè)樣(yàng)即可在不填寫自定義标題時調用默認标題，填寫自定義标題時調用自定義标題
