PHPCMS V9按栏目搜索

1、修改后台添加、修改内容时添加栏目id到搜索表中
找到 phpcmsmodelcontent_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 phpcmsmodelsearch_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phpcmsmodelscontentclassessearch_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phpcmsmodelssearchsearch_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 phpcmsmodelssearchindex.php 第25行
在 if(isset($_GET['q'])) { 下加上

$catid =$_GET['catid']?" AND catid = '$_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%'";
}

最后，进入数据库，找到表v9_search,添加字段catid，int,4
到网站后台全站索引一下，在搜索表单中添加以下代码就可以用了

<input type="hidden" name="catid" value="{$catid}"/>

缺点：如果该栏目下有子栏目，那么子栏目的文章是搜索不到的，只有在指定栏目ID下的直接文章才能被搜索到。
