1、首先需要说明的是这个功能需要在模板里面用到php标签，所以需要在后台模板引擎禁用标签里面解除这个标签的禁用，具体方法：后台——系统——系统基本参数——其它选项——模板引擎禁用标签：php将这个PHP去掉后保存就可以了。

2、修改arc.listview.class.php文件，这文件改动比较大，建议大家直接下载附件压缩包里面的文件替换，如果你之前对这个文件改动过的话，请在下载下来的压缩包里的这个文件里面搜索有“织梦技术研究中心”这些注释的这些地方，都是修改过的，然自己手动将有注释的代码插入到自己的文件里面！

3、修改extend.func.php文件，在其最后面添加如下代码：//dedecms联动筛选功能 By 织梦技术研究中心技术支持群：217479292 字符过滤函数02functionwwwcms_filter($str,$stype="inject") {03if($stype=="inject") {04$str = str_replace(05array("select","insert","update","delete","alter","cas","union","into","load_file","outfile","create","join","where","like","drop","modify","rename","'","/*","*","../","./"),06array("","","","","","","","","","","","","","","","","","","","","",""),07$str);08}elseif($stype=="xss") {09$farr = array("/\s+/",10"/<(\/?)(script|META|STYLE|HTML|HEAD|BODY|STYLE |i?frame|b|strong|style|html|img|P|o:p|iframe|u |em|strike|BR|div|a|TABLE|TBODY|object|tr|td |st1:chsdate|FONT|span|MARQUEE|body|title |\r\n|link |meta|\?|\%)([^>]*?)>/isU",11"/(<[^>]*)on[a-zA-Z]+\s*=([^>]*>)/isU",12);13$tarr = array(" ",14"",15"\\1\\2",16);17$str = preg_replace($farr, $tarr, $str);18$str = str_replace(19array("<",">","'","\"",";","/*","*","../","./"),20array("<",">","","","","","","",""),21$str);22}23return$str;24}2526/**27* 载入自定义表单(用于发布)28*29* @access public30* @param string $fieldset 字段列表31* @param string $loadtype 载入类型32* @returnstring33*/3435functionAddFilter($channelid, $type=1, $fieldsnamef, $defaulttid, $loadtype='autofield')36{37global $tid,$dsql,$id;38$tid = $defaulttid ? $defaulttid : $tid;39if($id!="")40{41$tidsq = $dsql->GetOne(" Select typeid From `#【分隔符】@__archives` where id='$id' ");42$tid = $tidsq["typeid"];43}44$nofilter = (isset($_REQUEST['TotalResult']) ?"&TotalResult=".$_REQUEST['TotalResult'] :'').(isset($_REQUEST['PageNo']) ?"&PageNo=".$_REQUEST['PageNo'] :'');45$filterarr = wwwcms_filter(stripos($_SERVER['REQUEST_URI'],"list.php?tid=") ? str_replace($nofilter,'', $_SERVER['REQUEST_URI']) : $GLOBALS['cfg_cmsurl']."/plus/list.php?tid=".$tid);46$cInfos = $dsql->GetOne(" Select * From `#【分隔符】@__channeltype` where id='$channelid' ");47$fieldset=$cInfos['fieldset'];48$dtp = new DedeTagParse();49$dtp->SetNameSpace('field','<','>');50$dtp->LoadSource($fieldset);51$dede_addonfields ='';52if(is_array($dtp->CTags))53{54foreach($dtp->CTags as $tid=>$ctag)55{56$fieldsname = $fieldsnamef ? explode(",", $fieldsnamef) : explode(",", $ctag->GetName());57if(($loadtype!='autofield'|| ($loadtype=='autofield'&& $ctag->GetAtt('autofield')==1)) && in_array($ctag->GetName(), $fieldsname) )58{59$href1 = explode($ctag->GetName().'=', $filterarr);60$href2 = explode('&', $href1[1]);61$fields_value = $href2[0];62$dede_addonfields .='<div class="scv-shaixuan"><b>'.$ctag->GetAtt('itemname').'：</b>';63switch ($type) {64case1:65$dede_addonfields .= (preg_match("/&".$ctag->GetName()."=/is",$filterarr,$regm) ?'<a title="全部" href="'.str_replace("&".$ctag->GetName()."=".$fields_value,"",$filterarr).'">全部</a>' :'<span>全部</span>').' ';6667$addonfields_items = explode(",",$ctag->GetAtt('default'));68for($i=0; $i<count($addonfields_items); $i++)69{70$href = stripos($filterarr,$ctag->GetName().'=') ? str_replace("=".$fields_value,"=".urlencode($addonfields_items[$i]),$filterarr) : $filterarr.'&'.$ctag->GetName().'='.urlencode($addonfields_items[$i]);//echo$href;71$dede_addonfields .= ($fields_value!=urlencode($addonfields_items[$i]) ?'<a title="'.$addonfields_items[$i].'" href="'.$href.'">'.$addonfields_items[$i].'</a>':'<span>'.$addonfields_items[$i].'</span>')." ";72}73$dede_addonfields .='</div>';74break;7576case2:77$dede_addonfields .='<select name="filter"'.$ctag->GetName().' onchange="window.location=this.options[this.selectedIndex].value">78'.'<option value="'.str_replace("&".$ctag->GetName()."=".$fields_value,"",$filterarr).'">全部</option>';79$addonfields_items = explode(",",$ctag->GetAtt('default'));80for($i=0; $i<count($addonfields_items); $i++)81{82$href = stripos($filterarr,$ctag->GetName().'=') ? str_replace("=".$fields_value,"=".urlencode($addonfields_items[$i]),$filterarr) : $filterarr.'&'.$ctag->GetName().'='.urlencode($addonfields_items[$i]);83$dede_addonfields .='<option value="'.$href.'"'.($fields_value==urlencode($addonfields_items[$i]) ?' selected="selected"':'').'>'.$addonfields_items[$i].'</option>84';85}86$dede_addonfields .= '</select><br/>87';88break;89}90}91}92}93echo$dede_addonfields;94}

4、到这里PHP文件修改的部分就完成了！接下来就需要给指定的模型添加字段了，这里需要注意的就是字段类型的选择，字段类型需要选择单选按钮或者使用select下拉框，如下图所示：

5、下面就是列表页模板筛选标签的调用了，筛选标签的调用很简单，一句代码就可以搞定，标签代码如下：

6、{dede:php}AddFilter(4,1,'linestyle,linethem,youdays,jgqujian');{/dede:php}

7、标签解释：AddFilter函数里面的第一个数字4是内容模型的id号，各个内容模型的id请到后台内容模型管理里面查看；第二个数字1是表示筛选的样式，1是使用超链接进行选择，2是使用select下拉框选择，具体可以自己设置了查看效果；第三个部分'linestyle,linethem,youdays,jgqujian'是要添加筛选功能的字段名，这里有4个字段，注意需要用半角逗号隔开。

8、到这里联动筛选单选的功能就弄完了，如果只需要单选功能的朋友可以直接用了。
