PHPCMS指定多栏目搜索的解决办法

2013-08-13 浏览:1847

1、修改后台添加、修改内容时添加栏目id到搜索表中
找到  phpcms\model\content_model.class.php 大概106、287行左右，一共两处
$this->search_api($id,$inputinfo);
修改为：
$this->search_api($id,$systeminfo['catid'],$inputinfo);
找到大概381行，将private function search_api 方法替换为以下代码

private function search_api($id = 0,$catid, $data = array(), $action = 'update') {
$type_arr = getcache('search_model_'.$this->siteid,'search');
$typeid = $type_arr[$this->modelid]['typeid'];
if($action == 'update') {
$fulltext_array = getcache('model_field_'.$this->modelid,'model');
foreach($fulltext_array AS $key=>$value){
if($value['isfulltext']) {
$fulltextcontent .= $data['system'][$key] ? $data['system'][$key] : $data['model'][$key];
}
}
$this->search_db->update_search($typeid ,$id, $fulltextcontent,addslashes($data['system']['title']).' '.addslashes($data['system']['keywords']),$data['system']['inputtime'],'',$catid);
} elseif($action == 'delete') {
$this->search_db->delete_search($typeid ,$id);
}
}

2、修改搜索模板文件
找到 phpcms\model\search_model.calss.php 的 21行左右
将 update_search 方法替换为：

public function update_search($typeid ,$id = 0,$data = '',$text = '',$adddate = 0, $iscreateindex=0,$catid) {
$segment = pc_base::load_sys_class('segment');
//分词结果
$fulltext_data = $segment->get_keyword($segment->split_result($data));
$fulltext_data = $text.' '.$fulltext_data;
if(!$iscreateindex) {
$r = $this->get_one(array('typeid'=>$typeid,'id'=>$id),'searchid');
}

if($r) {
$searchid = $r['searchid'];
$this->update(array('data'=>$fulltext_data,'adddate'=>$adddate,'catid'=>$catid),array('typeid'=>$typeid,'id'=>$id));
} else {
$siteid = param::get_cookie('siteid');
$searchid = $this->insert(array('typeid'=>$typeid,'id'=>$id,'adddate'=>$adddate,'data'=>$fulltext_data,'siteid'=>$siteid,'catid'=>$catid),true);
}
return $searchid;
}


3、修改后台更新全站缓存位置
找到phpcms\models\content\classes\search_api.class.php 的第 31行
将 $system_keys = 'id,inputtime'.implode(',',$system_keys);
修改为
$system_keys = 'id,inputtime,catid,'.implode(',',$system_keys);

找到 $temp['adddate'] = $r['inputtime'];在后面加上
$temp['catid'] = $r['catid'];


找到phpcms\models\search\search_admin.php大概第85行，将foreach修改为下面
foreach ($datas as $id=>$r) {
$this->db->update_search($typeid ,$id, $r['fulltextcontent'],$r['title'],$r['adddate'], 1,$r['catid']);
}
4、修改前台搜索程序
找到 phpcms\models\search\index.php 第25行
在 if(isset($_GET['q'])) { 下加上
        $catid =$_GET['catid']?" AND catid in ('$_GET[catid]')":'';
        然后在第57行左右，将
$commend = $this->db->get_one("`typeid` = '$typeid' $sql_time AND `data` like '%$q%'");
修改为
$commend = $this->db->get_one("`typeid` = '$typeid' $sql_time $catid AND `data` like '%$q%'");
再找到第84行左右将
//如果分词结果为空
if(!empty($segment_q)) {
$sql = "`siteid`= '$siteid' AND `typeid` = '$typeid' $sql_time AND MATCH (`data`) AGAINST ('$segment_q' IN BOOLEAN MODE)";
} else {
$sql = "`siteid`= '$siteid' AND `typeid` = '$typeid' $sql_time AND `data` like '%$q%'";
}
修改为
//如果分词结果为空
if(!empty($segment_q)) {
$sql = "`siteid`= '$siteid' AND `typeid` = '$typeid' $catid $sql_time AND MATCH (`data`) AGAINST ('$segment_q' IN BOOLEAN MODE)";
} else {
$sql = "`siteid`= '$siteid' AND `typeid` = '$typeid' $catid $sql_time AND `data` like '%$q%'";
}

5、最后一步，到数据库中，找到数据表  表前缀_search，在此表中加一字段  catid  int 4 做个索引。

6、模板代码：

{php $cat_id = 11;}
   {if $CATEGORYS[$cat_id][child]=='1'}
   {php $arrparent_id=str_replace($catid.",","",$CATEGORYS[$catid][arrchildid]);}
   {else}
   {php $arrparent_id=$CATEGORYS[$cat_id][arrchildid]}
   {/if}
