//挂接口：Add_Filter_Plugin('Filter_Plugin_ViewList_Core', 'zbpPlus_Exclude_Category');

function zbpPlus_Exclude_Category(&$type,&$page,&$category,&$author,&$datetime,&$tag,&$w,&$pagebar){
    global $zbp;

        //$w[]=array('<>','log_CateID',27);
        $w[] = array('NOT IN', 'log_CateID', explode('|',$filter));
        //以下是为了重建分页，过滤了分类，数量会发生变化
        $pagebar = new Pagebar($zbp->option['ZC_INDEX_REGEX'], true, true);
        $pagebar->PageCount = $zbp->displaycount;
