名站网址导航为大驾家提供DedeCMS站点程序站点教程相关的知识，比如织梦程序安装教程,织梦程序系统故障等教程。
假如站点中,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
站点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,这个字段网站的后台并没有添加.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,需要在网站的后台系统设置.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> |
/*字符过滤系统数据库函数*/
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("<",">","","","","","","",""),
$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.$filtersql; |
三,替换系统数据库函数function GetArcList()为全新的
function GetArcList($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')

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

else {

}
//新增综合排序：默认 最热 最新 价高 价低
$addtable = $this->ChannelUnit->ChannelInfos['addtable'];
