ZendFrame实现一个投票模块
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');
}
}
}
?>
