思路分析:获取用户ip,判断该ip 是否被禁用,然后判断今天有没有投了 再做出相应的操作...

 

主要步骤如下:

 

配置一下application.ini 让项目可以连接到指定的数据库

 

[mysql]

db.adapter = PDO_MYSQL

db.params.host = localhost

db.params.username = root

db.params.password =

db.params.dbname=votedb

 

初始化数据库适配器

 

 // 做一个父类,专门供其它控制器来继承的

 class BaseController extends Zend_Controller_Action{

  public function init(){

  //初始化数据库适配器

  $url = constant("APPLICATION_PATH").DIRECTORY_SEPARATOR.'configs'.DIRECTORY_SEPARATOR.'application.ini';

  $dbconfig = new Zend_Config_Ini($url,"mysql");

  $db = Zend_Db::factory($dbconfig->db);

  Zend_Db_Table::setDefaultAdapter($db);

  }

 }

 

//创建表模型

 

//这里一定要继承Zend_db_Table,否则就不是表模型

 class Item extends Zend_Db_Table{

  protected $_name = 'item';

 }

//投票控制器

 

require_once 'BaseController.php';

require_once APPLICATION_PATH.'/models/Item.php';

require_once APPLICATION_PATH.'/models/Filter.php';

require_once APPLICATION_PATH.'/models/VoteLog.php';

 

 

class VoteController extends BaseController{

public function voteAction(){

 

$item_id = $this->getRequest()->getParam('itemid','no');  //获取id

//用于获取ip 地址$_SERVER['REMOTE_ADDR']

  $ip = $this->getRequest()->getServer('REMOTE_ADDR');

  //看看这个ip是否被禁用

  $filterModel = new Filter();

  $filters =  $filterModel->fetchAll("ip='$ip'")->toArray();

  if(count($filters)>=1){

  $this->view->info="你被警用了!";

  //成功,跳转到一个全局的视图

  $this->_forward('err','global');

  return;

  }

  

//先看voteLOg 这个表今天有没有透过一次

$today=date('Ymd');//今天的时间

$voteLogModel = new VoteLog();

$where = "ip='$ip' AND vote_date=$today";

$res = $voteLogModel->fetchAll($where)->toArray();

if(count($res)>0){  //如果大于0表示已经投 了

$this->render('error');

return ;

}else{

//更新item的vote_count,添加更新日志

$data = array(

'ip' => $ip,

'vote_date'=>$today,

'item_id'=>$item_id

);

if($voteLogModel->insert($data)>0){  //如果更新成功要更改item 表

$itemModel = new Item();

//通过主键直接获取对应的item

$item = $itemModel->find($item_id)->toArray();

 

$newvote = $item[0]['vote_count']+1;

$set = array(

'vote_count'=>$newvote

);

$where = "id=$item_id";

$itemModel->update($set, $where);

}

$this->render('ok');

}

}

}
