phpcmsv9全站搜索,不限模型！

phpcms不限模型搜索的设置方法

phpcmsv9全站搜索,不限模型,今天又涨知识了。大家都知道，phpcms搜索时按照模型来搜索的，用了这个方法后，就可以全站搜索

简单修改一下v9默认的搜索功能，可以不按模型搜索全站内容

下面是被修改后的search模块中的index.php文件

db = pc_base::load_model('search_model');    $this->content_db = pc_base::load_model('content_model');  }    /**   * 关键词搜索   */  public function init() {    //获取siteid    $siteid = isset($_REQUEST['siteid']) && trim($_REQUEST['siteid']) ? intval($_REQUEST['siteid']) : 1;    $SEO = seo($siteid);     //搜索配置    $search_setting = getcache('search');    $setting = $search_setting[$siteid];     $search_model = getcache('search_model_'.$siteid);    $type_module = getcache('type_module_'.$siteid);     if(isset($_GET['q'])) {      if(trim($_GET['q'])=='') {        header('Location: '.APP_PATH.'index.php?m=search');exit;      }      $typeid = empty($_GET['typeid']) ? 0 : intval($_GET['typeid']);      $time = empty($_GET['time']) || !in_array($_GET['time'],array('all','day','month','year','week')) ?

然后在header.html模板（不在这里，就在其他的搜索框页面）上面增加一个"不限"的搜索条件，将typeid对应的值为0，search中的index.html和lists.html也做相同处理，效果就出来那，这样只要不选择模型那么搜索出来的结果就是所有模型中符合条件的数据。
