dedecms织梦channel标签中调用栏目seotitle

在使用织梦5.7系统做网站时,会经常用到{dede:channel}标签,有时我们需要调用栏目seotitle字段。比如说:   {dede:channel type=’sun’ typeid=’1’}   <a href=’[field:typelink/]’>[field:typename/]</a>   {/dede:channel}   [field:typename/]这里要使用{dede:field.seotitle /},也就是说在织梦{dede:channel}标签中调用栏目seotitle,如何实现?   如果要想在织梦模板{dede:channel}标签中调用栏目seotitle,我们需要做一下简单的二次开发,步骤如下:   打开/include/taglib文件夹下的channel.lib.php,找到78行到94行:     if($type==’top’)       {           $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath             From `zuimoban_arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line ";       }       else if($type==’son’)       {           if($typeid==0) return ’’;           $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath             From `zuimoban_arctype` WHERE reid=’typeid′Andishidden<>1orderbysortrankasclimit0,typeid′Andishidden<>1orderbysortrankasclimit0,line ";       }       else if($type==’self’)       {           if($reid==0) return ’’;           $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath               FROM `zuimoban_arctype` WHERE reid=’reid′Andishidden<>1orderbysortrankasclimit0,reid′Andishidden<>1orderbysortrankasclimit0,line ";       }   在sql语句里补充:Select id,typename,seotitle,.......就可以调用,如下图:
