在建站过种中经常看到多字段内容筛选的功能，昨天分享了一个极致CMS多字段内容筛选的实现方法，今天黑猫查查网再分享一个YzmCMS内容筛选的实现方法与详细代码。
首先找到文件：/application/index/controller/index.class.php，找到搜索函数，下面增加一个函数，
/**
* 精确搜索/多条件
*/public function initpo(){ $site = get_config();
$modelid = isset($_GET['modelid']) ? intval($_GET['modelid']) : 1; $modelinfo = get_modelinfo(); $modelarr = array(); foreach($modelinfo as $val){ $modelarr[$val['modelid']] = $val['tablename'];
} if(!isset($modelarr[$modelid])) showmsg('模型不存在！', 'stop');
/**
*加入搜索条件
*/
$where ="`status` = 1"; $hangye_array = array('1'=>'工业','2'=>'互联网','3'=>'农业'); $guoj_array = array('1'=>'中国','2'=>'日本','3'=>'法国'); $hangye = str_replace('%', '', new_html_special_chars(strip_tags(trim($_GET['hangye'])))); $guoj = str_replace('%', '', new_html_special_chars(strip_tags(trim($_GET['guoj'])))); $qq1 = str_replace('%', '', new_html_special_chars(strip_tags(trim($hangye_array[$hangye])))); $qq2 = str_replace('%', '', new_html_special_chars(strip_tags(trim($guoj_array[$guoj])))); if(isset($hangye)&&($hangye!=0)) $where .= " AND hangye= '$qq1' "; if(isset($guoj)&&($guoj!=0)) $where .= " AND guoj= '$qq2' "; $db = D($modelarr[$modelid]); $total = $db->where($where)->total(); $page = new page($total, $this->offset); $search_data = $db->field('id,title,description,inputtime,updatetime,click,thumb,nickname,url,catid,flag,color,hangye,guoj')->where($where)->order('id DESC')->limit($page->limit())->select();
$pages = '<span class="pageinfo">共<strong>'.$page->total().'</strong>页<strong>'.$total.'</strong>条记录</span>'.$page->getfull(); include template($this->module, 'searchb');
}再新建模板文件为searchb.html

function getQueryString(){

if(result == null){
return "";
}
for(var i = 0; i < result.length; i++){
result[i] = result[i].substring(1);
}
return result;
}
function goSort(name,value){
var string_array = getQueryString();
var oldUrl = (document.URL.indexOf("search")==-1)?document.URL+"/search/index/initpo.html":document.URL;
var newUrl;
if(string_array.length>0)//如果已经有筛选条件
{ var repeatField = false;

//跳转

function setSelected(name,value){

<div class="yzm-content-box yzm-main-left yzm-news-list">
<div class="yzm-title">

</div>
{loop $search_data $v}
<div class="yzm-news">

{/loop}
<div id="page">{$pages}</div>
</div>
<div class="yzm-main-right">

{m:include "index","footer"}然后再需要用到内容筛选的模板页面加如下代码：
<script language="javascript"> function getQueryString(){
var result = location.search.match(new RegExp("[\?\&][^\?\&]+=[^\?\&]+","g"));
if(result == null){
return "";
}
for(var i = 0; i < result.length; i++){
result[i] = result[i].substring(1);
}
return result;
}
function goSort(name,value){
var string_array = getQueryString();
var oldUrl = (document.URL.indexOf("search")==-1)?"search/index/initpo.html":document.URL;
var newUrl;
if(string_array.length>0)//如果已经有筛选条件 { var repeatField = false;
for(var i=0;i<string_array.length;i++){
if(!(string_array[i].indexOf(name)==-1)){
repeatField = true;//如果有重复筛选条件，替换条件值 newUrl = oldUrl.replace(string_array[i],name+"="+value);
}
}
//如果没有重复的筛选字段 if(repeatField == false){
newUrl = oldUrl+"&"+name+"="+value;
}
}else{//如果还没有筛选条件 newUrl = oldUrl+"?"+name+"="+value;
}
//跳转 window.location = newUrl;
}
function setSelected(name,value){
var all_li = $("#"+name).find("li");
//清除所有li标签的selected类 all_li.each(function(){
$(this).removeClass("selected");
});
//为选中的li增加selected类 all_li.eq(value).addClass("selected");
}
$(document).ready(function(){
var string_array = getQueryString();
for(var i=0;i<string_array.length;i++){
var tempArr = string_array[i].split("=");
setSelected(tempArr[0],tempArr[1]);//设置选中的筛选条件 }
});
