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

(此图片来源于网络，如有侵权，请联系删除! )

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

{dede:php}if($_GET['myorder']=='hot'){echo '最热';}else{echo '最热';}{/dede:php}

{dede:php}if($_GET['myorder']=='new'){echo '最新';}else{echo '最新';}{/dede:php}

{dede:php}if($_GET['myorder']=='price_high'){echo '价高';}else{echo '价高';}{/dede:php}

{dede:php}if($_GET['myorder']=='price_low'){echo '价低';}else{echo '价低';}{/dede:php}

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+/" ,

"/]*?)>/isU",

"/(]*)on[a-zA-Z]+\s*=([^>]*>)/isU",

);

$tarr = array(" ",

"",

"\\1\\2",

);

$str = preg_replace($farr, $tarr, $str);

$str = str_replace(

array( "", "'", "\"", ";", "/*", "*", "../", "./"),

array("<",">","","","","","","",""),

$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')

{

global $cfg_list_son;

$typeid=$this->TypeID;

if($row=='') $row = 10;

if($limitstart=='') $limitstart = 0;

if($titlelen=='') $titlelen = 100;

if($infolen=='') $infolen = 250;

if($imgwidth=='') $imgwidth = 120;

if($imgheight=='') $imgheight = 120;

if($listtype=='') $listtype = 'all';

if($orderWay=='') $orderWay = 'desc';

if($orderby=='') {

$orderby='default';

}

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") {

$ordersql=" order by arc.id $orderWay";

}

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

$ordersql = " order by arc.click $orderWay";

}

else if($orderby=="lastpost") {

$ordersql = " order by arc.lastpost $orderWay";

}else if($orderby=="weight") {

$ordersql = " order by arc.weight $orderWay";

}

else {

$ordersql=" order by arc.sortrank $orderWay";

}

//新增综合排序：默认 最热 最新 价高 价低

$addtable = $this->ChannelUnit->ChannelInfos['addtable'];

if($_GET['myorder']=='默认'){

$orderby='sortrank';

$ordersql = " order by arc.sortrank $orderWay";

}elseif($_GET['myorder']=='hot'){

$orderby='hot';

$ordersql = " order by arc.click $orderWay";

}

elseif($_GET['myorder']=='new'){

$orderby='id';

$ordersql = " order by arc.id $orderWay";

}

elseif($_GET['myorder']=='price_high'){

$orderby='price_high';

$ordersql = " order by ".$addtable.".price ".$orderWay;

}

elseif($_GET['myorder']=='price_low'){

$orderby='price_low';

$ordersql = " order by ".$addtable.".price asc";

}

elseif($_GET['myorder']=='mian_high'){

$orderby='mian_high';

$ordersql = " order by ".$addtable.".mian ".$orderWay;

}

elseif($_GET['myorder']=='mian_low'){

$orderby='mian_low';

$ordersql = " order by ".$addtable.".mian asc";

}

else{

$ordersql=" order by arc.id $orderWay";

}

//多条件查询新增,获得附加表的相关信息/

获得一个单列的文档列表继续

if($addtable!="")

{

$addJoin = " left join `$addtable` on arc.id = ".$addtable.'.aid ';

$addField = '';

$fields = explode(',',$this->ChannelUnit->ChannelInfos['listfields']);
