dedecms 实现织梦搜索页面调用 文章功能

直接进入主题,今天使用dedecms织梦开源系统做企业网站,要实现在搜索页面里调用推荐新闻的,但是dedecms织梦在搜索页面里不可以直接使用以下代码调用文章的:

{dede:arclist flag= 'c'  titlelen=42 row=6}   [field:title/]    [field:description  function = 'cn_substr(@me,80)' /]...  {/dede:arclist} 

如是笔者硬是把搜索页面的内核代码完全的看了一遍,终于实现了搜索页面调用[推荐文章].

为什么搜索页面不能调用新闻呢,下面我来告诉大家,找到arc.searchview.class.php文件,看以下代码:

function  Display()      {             foreach ( $this ->dtp->CTags  as   $tagid => $ctag )          {               $tagname  =  $ctag ->GetName();               if ( $tagname == "list" )              {                   $limitstart  = ( $this ->PageNo-1) *  $this ->PageSize;                   $row  =  $this ->PageSize;                   if (trim( $ctag ->GetInnerText())== "" )                  {                       $InnerText  = GetSysTemplets( "list_fulllist.htm" );                  }                   else                   {                       $InnerText  = trim( $ctag ->GetInnerText());                  }                   $this ->dtp->Assign( $tagid ,                   $this ->GetArcList( $limitstart ,                   $row ,                   $ctag ->GetAtt( "col" ),                   $ctag ->GetAtt( "titlelen" ),                   $ctag ->GetAtt( "infolen" ),                   $ctag ->GetAtt( "imgwidth" ),                   $ctag ->GetAtt( "imgheight" ),                   $this ->ChannelType,                   $this ->OrderBy,                   $InnerText ,                   $ctag ->GetAtt( "tablewidth" ))                  );              }               else   if ( $tagname == "pagelist" )              {                   $list_len  = trim( $ctag ->GetAtt( "listsize" ));                   if ( $list_len == "" )                  {                       $list_len  = 3;                  }                   $this ->dtp->Assign( $tagid , $this ->GetPageListDM( $list_len ));              }               else   if ( $tagname == "likewords" )              {                   $this ->dtp->Assign( $tagid , $this ->GetLikeWords( $ctag ->GetAtt( 'num' )));              }               else   if ( $tagname == "hotwords" )              {                   $this ->dtp->Assign( $tagid ,lib_hotwords( $ctag , $this ));              }               else   if ( $tagname == "field" )              {                   //类别的指定字段                    if (isset( $this ->Fields[ $ctag ->GetAtt( 'name' )]))                  {                       $this ->dtp->Assign( $tagid , $this ->Fields[ $ctag ->GetAtt( 'name' )]);                  }                   else                   {                       $this ->dtp->Assign( $tagid , "" );                  }              }               else   if ( $tagname == "channel" )              {                   //下级频道列表                    if ( $this ->TypeID>0)                  {                       $typeid  =  $this ->TypeID;  $reid  =  $this ->TypeLink->TypeInfos[ 'reid' ];                  }                   else                   {                       $typeid  = 0;  $reid =0;                  }                   $GLOBALS [ 'envs' ][ 'typeid' ] =  $typeid ;                   $GLOBALS [ 'envs' ][ 'reid' ] =  $typeid ;                   $this ->dtp->Assign( $tagid ,lib_channel( $ctag , $this ));              } //End if          elseif ( $tagname == "arclist" ) //这是笔者自己加的代码只要加上这行代码我们就能调用[acrlist]标签        {              MakeOneTag( $this ->dtp, $this );       } //开源软件:phpfensi测试数据           }           global   $keyword ,   $oldkeyword ;           if (! empty empty ( $oldkeyword ))  $keyword  =  $oldkeyword ;           $this ->dtp->Display();      } 

只要把代码中加注释的那段语句加入arc.searchview.class.php文件里就可以实现搜索页面调用文章.
