织梦让dede:channel支持调用[field:seotitle/]

在开发织梦模板的时候,在调用 dede:channel标签时,需要将栏目中 seotitle中的内容也可以调用出来。默认是不支持调用的。做了一下二次开发,让channel标签支持seotitle的调用。    开发方法如下:   1、打开 include/taglib/channel.lib.php,找到如下代码:

if($type=='top') 
    { 
        $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
          From `dede_arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line "; 
    } 
    else if($type=='son') 
    { 
        if($typeid==0) return ''; 
        $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
          From `dede_arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit 0, $line "; 
    } 
    else if($type=='self') 
    { 
        if($reid==0) return ''; 
        $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
            FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line "; 
    }
修改为:

if($type=='top') 
    { 
        $sql = "SELECT id,typename,seotitle,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
          From `dede_arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line "; 
    } 
    else if($type=='son') 
    { 
        if($typeid==0) return ''; 
        $sql = "SELECT id,typename,seotitle,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
          From `dede_arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit 0, $line "; 
    } 
    else if($type=='self') 
    { 
        if($reid==0) return ''; 
        $sql = "SELECT id,typename,seotitle,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
            FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line "; 
    }

前台模板调用方法:   {dede:channel type='top' row='10'}    <li><a href='[field:typeurl/]'>[field:typename/]<br/>[field:seotitle/]</a></li>    {/dede:channel}    完成。
