YzmCMS多内容筛选实现代码
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，今天小郭再分享一个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;
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){

}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 tempArr = string_array[i].split("=");
setSelected(tempArr[0],tempArr[1]);//设置选中的筛选条件

<body>
<div class="search_text" id="hangye">
<h1>行业：</h1>
<ul>
<li class="selected"><a href="javascript:goSort('hangye',0)" rel="external nofollow" >全部</a></li>
<li><a href="javascript:goSort('hangye',1)" rel="external nofollow" >工业</a></li>
<li><a href="javascript:goSort('hangye',2)" rel="external nofollow" >互联网</a></li>
<li><a href="javascript:goSort('hangye',3)" rel="external nofollow" >农业</a></li>
</ul>
</div>
<div class="search_text" id="guoj">
<h1>颜色 ：</h1>
<ul>
<li class="selected"><a href="javascript:goSort('guoj',0);" rel="external nofollow" >全部</a> </li>
<li><a href="javascript:goSort('guoj',1);" rel="external nofollow" >中国</a></li>

<li><a href="javascript:goSort('guoj',3);" rel="external nofollow" >法国</a></li>
</ul>
</div>
<div class="yzm-content-box yzm-main-left yzm-news-list">
<div class="yzm-title">
<h2>“{$q}” 的搜索结果，共<span>{$total}</span>条</h2>
</div>
{loop $search_data $v}
<div class="yzm-news">
<a href="{$v[url]}" class="yzm-news-img">
<img src="{get_thumb($v['thumb'])}" alt="{$v[title]}" title="{$v[title]}" />
</a>
<div class="yzm-news-right">
{if strstr($v['flag'],'1')}<em>顶</em>{/if} <!-- 内容属性 -->
<a href="{$v[url]}">{title_color($v['title'], $v['color'])}</a>
<p>{$v[description]}</p>
<div class="yzm-news-tags">

{m:get sql="SELECT id,tag FROM yzmcms_tag_content AS a LEFT JOIN yzmcms_tag AS b ON a.tagid=b.id WHERE aid=$aid" limit="5" return="tag_data"}
{loop $tag_data $val}
<a href="{tag_url($val['id'])}" target="_blank" >{$val[tag]}</a>
{/loop}
</div>
</div>
</div>
{/loop}
<div id="page">{$pages}</div>
</div>
<div class="yzm-main-right">
</div>
{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
}
});
</script>
<div class="search_text" id="hangye">

<ul>
<li class="selected"><a href="javascript:goSort('hangye',0)" rel="external nofollow" >全部</a></li>

<li><a href="javascript:goSort('hangye',2)" rel="external nofollow" >互联网</a></li>
<li><a href="javascript:goSort('hangye',3)" rel="external nofollow" >农业</a></li>
</ul>
</div>
<div class="search_text" id="guoj">

</ul>
