织梦列表页点击按价格按评分按更新按点击排序进行筛选方法

假如网站中,有一个价格字段trueprice,我希望根据价格从小到大,或从大到小进行点击筛选，或按热门,最新商品进行排序,效果图如下

列表模板上增加排序,myorder=hot注意,其中增加了一个虚拟字段myorder,这个字段后台并没有添加.他只是一个排序的标志符,需要最后排除掉.

另外,模板上用到了{dede:php}标签,需要在后台系统设置.系统基本参数,其它设置中,去掉对php模板标签的限制.

模板如下

 <a class="ib padding-right"  href="/plus/list.php?tid={dede:field.typeid/}&myorder=hot">{dede:php}if($_GET['myorder']=='hot'){echo '<span>最热</span>';}else{echo '最热';}{/dede:php}</a>
 <a class="ib padding-right" href="/plus/list.php?tid={dede:field.typeid/}&myorder=new">{dede:php}if($_GET['myorder']=='new'){echo '<span>最新</span>';}else{echo '最新';}{/dede:php}</a>
 <a class="ib padding-right" href="/plus/list.php?tid={dede:field.typeid/}&myorder=price_high">{dede:php}if($_GET['myorder']=='price_high'){echo '<span>价高</span>';}else{echo '价高';}{/dede:php}</a>
<a class="ib padding-right"href="/plus/list.php?tid={dede:field.typeid/}&myorder=price_low">{dede:php}if($_GET['myorder']=='price_low'){echo '<span>价低</span>';}else{echo '价低';}{/dede:php}</a>

首先,在自定义函数中\include\extend.func.php增加非法过滤函数

/*字符过滤函数*/
function snail_filter($str,$stype="inject") {
    if ($stype=="inject")  {
        $str = str_replace(
               array( "select", "insert", "update", "delete", "alter", "cas", "union", "into", "load_file", "outfile", "create", "join", "where", "like", "drop", "modify", "rename", "'", "/*", "*", "../", "./"),
   array("","","","","","","","","","","","","","","","","","","","","",""),
   $str);
    } else if ($stype=="xss") {
        $farr = array("/\s+/" ,
                      "/<(\/?)(script|META|STYLE|HTML|HEAD|BODY|STYLE |i?frame|b|strong|style|html|img|P|o:p|iframe|u|em|strike|BR|div|a|TABLE|TBODY|object|tr|td|st1:chsdate|FONT|span|MARQUEE|body|title|\r\n|link|meta|\?|\%)([^>]*?)>/isU", 
          "/(<[^>]*)on[a-zA-Z]+\s*=([^>]*>)/isU",
          );
        $tarr = array(" ",
                      "",
          "\\1\\2",
          ); 
        $str = preg_replace($farr, $tarr, $str);
        $str = str_replace(
               array( "<", ">", "'", "\"", ";", "/*", "*", "../", "./"),
   array("&lt;","&gt;","","","","","","",""),
   $str);
    }
    return $str;
}

然后,在include/arc.listview.class.php里面增加排序判断及分页的定义,并排除myorder字段

一,修改CountRecord(),在第二行的下面

在if(empty(cfgneedtypeid2))cfgneedtypeid2))cfg_need_typeid2 = ‘N’的下面

增加

 //新增,多条件筛选 ,获得附加表的相关信息
        $addtable  = $this->ChannelUnit->ChannelInfos['addtable'];
        if($addtable!="")
        {
            $addJoin = " LEFT JOIN `$addtable` ON arc.id = ".$addtable.'.aid ';
            $addField = '';
            $fields = explode(',',$this->ChannelUnit->ChannelInfos['listfields']);
            foreach($fields as $k=>$v)
            {
                $nfields[$v] = $k;
            }
            if(is_array($this->ChannelUnit->ChannelFields) && !empty($this->ChannelUnit->ChannelFields))
            {
                foreach($this->ChannelUnit->ChannelFields as $k=>$arr)
                {
                    if(isset($nfields[$k]))
                    {
                        if(!empty($arr['rename'])) {
                            $addField .= ','.$addtable.'.'.$k.' as '.$arr['rename'];
                        }
                        else {
                            $addField .= ','.$addtable.'.'.$k;
                        }
                    }
                }
            }
            if (isset($_REQUEST['tid'])){
                $myget=$_GET;
                unset($myget['myorder']);//删除一个字段 
                //删除数组中的个别元素,活动状态,进行中,刚结束等,这些值是根据结束时间动态判断的,所以,数据库中并不存在,需要过滤掉这个sql查询条件
                foreach($_GET as $key => $value) {
                    //过滤掉不在$addtable表格中的字段,本次不负责处理
                    //print_r($_GET);exit;
                    $filtersql .= ($key!="q"&$key!="tid" && $key!="TotalResult" && $key!="PageNo") ? " AND $addtable.".snail_filter($key)." = '".snail_filter(urldecode($value))."'" : '';
                }
            }
        }
        else
        {
            $addField = '';
            $addJoin = '';
        }
        //新增结束
        //统计数据库记录

二、继续找到

$cquery = "SELECT COUNT(*) AS dd FROMdede_arctinyarc WHERE ".$this->addSql;

修改为

$cquery = "SELECT COUNT(*) AS dd FROM `dede_arctiny` arc $addJoin WHERE ".$this->addSql.$filtersql;

三,替换函数function GetArcList()为全新的

function GetArcList($limitstart=0,$row=10,$col=1,$titlelen=30,$infolen=250,
    $imgwidth=120,$imgheight=90,$listtype="all",$orderby="default",$innertext="",$tablewidth="100",$ismake=1,$orderWay='desc')

        }
        else {
            $orderby=strtolower($orderby);
        }
        $tablewidth = str_replace('%','',$tablewidth);
        if($tablewidth=='') $tablewidth=100;
        if($col=='') $col=1;
        $colWidth = ceil(100/$col);
        $tablewidth = $tablewidth.'%';
        $colWidth = $colWidth.'%';
        $innertext = trim($innertext);
        if($innertext=='') {
            $innertext = GetSysTemplets('list_fulllist.htm');
        }
        //排序方式
        $ordersql = '';
        if($orderby=="senddate" || $orderby=="id") {

        }
        else if($orderby=="hot" || $orderby=="click") {
