如何设置dedecms标题标签、关键词标签、描述标签
织梦。在dedecms中具有分页浏览的新闻列表页新闻栏目内容调用标是织梦,如果某个字段需要在前台列表页显示,则在前台参数中勾选“使字段可以在列表的底层模板中获得(自定义字段默认仅能在文档模板显示。
织梦模板之家告诉您应该这么写:
很多时候我们在页面某一板块想调用多个栏目的信息,不如说你建立10个栏目,但是在这一板块想调用其中3个栏目的信息,怎么办呢?
这样就用到typeid="id" 这个参数了,调用栏目的写法是这样的:typeid="1,4,8",把这个参数放入相应的标签中即可。
如头条调用:
{dede:arclist row=1 titlelen=28 orderby=pubdate} 那么就改成
{dede:arclist row=1 titlelen=28 orderby=pubdate typeid="1,4,8"} 这样头条就只调用第1,第4,第8这个3个栏目的内容了。
按照这个方法,你可以灵活运用到其他板块中,把栏目ID写进去用“,”隔开即可。
首页:
<title>{dede:globalcfg_webname/}</title>
<meta name="keywords" content="{dede:globalcfg_keywords/}" />
<meta name="description" content="{dede:globalcfg_description/}" />
设置是在“系统->系统基本参数->站点设置”里的“网站名称”、“站点默认关键字”、“站点描述”。
栏目页:
<title>{dede:fieldseotitle/}</title>
<meta name="keywords" content="{dede:fieldkeywords/}" />
<meta name="description" content="{dede:fielddescription/}" />
设置是在各栏目“修改->高级选项”里面的“SEO标题”、“关键字”、“栏目描述”。
文章页:
个人经验是文章标题做title和keywords,文章简介做description
<title>{dede:fieldtitle/}</title>
<meta name="keywords" content="{dede:fieldtitle/}" />
<meta name="description" content="{dede:fielddescription/}" />

二、在模板调用
实例:
{dede:channel type='son' typeid='改成你的大栏目ID'}[field:typename/]
<ul>
[field:sonchannel0]
<li><a href="[field:typelink/]">[field:typename/]</a></li>
[field:sonchannel1]
<li><a href="[field:typelink/]">---[field:typename/]</a></li>
[field:sonchannel2]
<li><a href="[field:typelink/]">===[field:typename/]</a></li>
[field:sonchannel3]
<li><a href="[field:typelink/]">===[field:typename/]</a></li>
[/field:sonchannel3]
[/field:sonchannel2]
[/field:sonchannel1]
[/field:sonchannel0]
</ul>
{/dede:channel}
模板调用 [field:sonchannel0] [/field:sonchannel0] 这个是用来取子栏目用的(使用[sonchannel+数字] 作为标签名是为了防止嵌套的时候无法正确解析标签)
这个的作用就是当你的栏目有很多子栏目 无限分级的时候方便你取子栏目的。
