织梦dede拓展channel标签实现limit功能

//limit条件
    $limit = trim(eregi_replace('limit','',$limit));
    if($limit!='') $limitsql = " limit $limit ";
    else $limitsql = " limit 0,7 ";

    $orwhere = '';
    if(isset($orwheres[0])) {
        $orwhere = join(' And ',$orwheres);
        $orwhere = ereg_replace("^ And",'',$orwhere);
        $orwhere = ereg_replace("And[ ]{1,}And",'And ',$orwhere);
    }
    if($orwhere!='') $orwhere = " where $orwhere ";//二次开发

function lib_channel(&$ctag,&$refObj)
{
    global $dsql;

    $attlist = "typeid|0,reid|0,row|100,col|1,type|son,currentstyle|,cacheid|";
    FillAttsDefault($ctag->CAttribute->Items,$attlist);
    extract($ctag->CAttribute->Items, EXTR_SKIP);
    $innertext = $ctag->GetInnerText();
    $line = empty($row) ? 100 : $row;
