修改dede源码,让dede:channelartlist排除指定typeid

时间： 2018-12-11 08:44 阅读：次作者：素材无忧网

找到 \include\taglib\channelartlist.lib.php, 查找 $attlist

查找:
$dsql->SetQuery("Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath from `dede_arctype` where $tpsql order by sortrank asc limit $totalnum");

在其前面添加(注意是在前面添加)：

//否定指定ID
if($notypeid!=0) {
$tpsql = $tpsql."and not(id in($notypeid)) ";
}

模板调用:
{dede:channelartlist typeid ='114' notypeid='123,124,125,126,127,128'}
其中notypeid='123,124,125,126,127,128' 中的 123,124,125,126,127,128 为114的子栏目

修改后的channelartlist.lib.php

<?phpif(!defined('DEDEINC')) exit('Request Error!');require_once(DEDEINC.'/arc.partview.class.php');functionlib_channelartlist(&$ctag,&$refObj){    global$dsql,$envs,$_sys_globals;    //处理标记属性、innertext    $attlist= 'typeid|0,row|20,cacheid|,notypeid|0';    FillAttsDefault($ctag->CAttribute->Items,$attlist);    extract($ctag->CAttribute->Items, EXTR_SKIP);    $innertext= trim($ctag->GetInnerText());    $artlist= '';    //读取固定的缓存块    $cacheid= trim($cacheid);    if($cacheid!='') {        $artlist= GetCacheBlock($cacheid);        if($artlist!='') return$artlist;    }        if(empty($typeid))    {        $typeid= ( !empty($refObj->TypeLink->TypeInfos['id']) ?  $refObj->TypeLink->TypeInfos['id'] : 0 );    }        if($innertext=='') $innertext= GetSysTemplets('part_channelartlist.htm');    $totalnum= $row;    if(empty($totalnum)) $totalnum= 20;    //获得类别ID总数的信息    $typeids= array();    if($typeid==0 || $typeid=='top') {        $tpsql= " reid=0 And ispart<>2 And ishidden<>1 And channeltype>0 ";    }    else    {        if(!ereg(',',$typeid)) {            $tpsql= " reid='$typeid' And ispart<>2 And ishidden<>1 ";        }        else{            $tpsql= " id in($typeid) And ispart<>2 And ishidden<>1 ";        }    }        //否定指定ID    if($notypeid!=0) {        $tpsql= $tpsql."and not(id in($notypeid)) ";    }        $dsql->SetQuery("Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath                                             from `dede_arctype` where $tpsqlorder by sortrank asc limit $totalnum");    $dsql->Execute();    while($row= $dsql->GetArray()) {        $typeids[] = $row;    }    if(!isset($typeids[0])) return'';    $GLOBALS['itemindex'] = 0;    $GLOBALS['itemparity'] = 1;    for($i=0;isset($typeids[$i]);$i++)    {        $GLOBALS['itemindex']++;        $pv= newPartView($typeids[$i]['id']);        $pv->Fields['typeurl'] = GetOneTypeUrlA($typeids[$i]);        $pv->SetTemplet($innertext,'string');        $artlist.= $pv->GetResult();        $GLOBALS['itemparity'] = ($GLOBALS['itemparity']==1 ? 2 : 1);    }    //注销环境变量，以防止后续调用中被使用    $GLOBALS['envs']['typeid'] = $_sys_globals['typeid'];    $GLOBALS['envs']['reid'] = '';    if($cacheid!='') {        WriteCacheBlock($cacheid, $artlist);    }    return$artlist;}?>
