ZendFramework小例子——投票

建立項目

1.cmd內進入ZendFramework內的bin用命令新建zf項目

zf.bat create project G:/xampp/htdocs/VoteSys

2.將Zend文件放入新建項目的library

設置虛擬主機

1.xampp\apache\conf\extra\httpd-vhosts.conf內添加

<VirtualHost *:8081> 
    ServerAdmin VoteSys.com
    DocumentRoot "/xampp/htdocs/VoteSys/public" 
    ServerName VoteSys.com 
    DirectoryIndex index.php 
    <Directory "/xampp/htdocs/VoteSys/public"> 
    Options FollowSymLinks 
    AllowOverride All 
    Order allow,deny 
    Allow from all 
    </Directory> 
    ErrorLog "logs/VoteSys-error.log"
    CustomLog "logs/VoteSys-access.log" common
</VirtualHost>

2.C:\Windows\System32\drivers\etc\hosts內配置

127.0.0.1           VoteSys.com

建立數據庫及表格

1.item表

DROP TABLE IF EXISTS `item`;
CREATE TABLE `item` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(64) NOT NULL,
  `description` varchar(128) NOT NULL,
  `vote_count` bigint(20) unsigned DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

2.vote_log表

DROP TABLE IF EXISTS `vote_log`;
CREATE TABLE `vote_log` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `ip` varchar(20) NOT NULL,
  `vote_date` bigint(20) NOT NULL,
  `item_id` bigint(20) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

3.filter表

DROP TABLE IF EXISTS `filter`;
CREATE TABLE `filter` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `ip` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

設置VoteSys內的數據庫連接信息

1.htdocs\VoteSys\application\configs\application.ini內配置

[mysql]
db.adapter = PDO_MYSQL
db.params.host = localhost
db.params.username = admin
db.params.password = admin
db.params.dbname = test

2.新建\htdocs\VoteSys\application\controllers\DBController.php

class DBController extends Zend_Controller_Action
{
    public function init()
    {
        //初始化數據庫適配器
        $url = constant("APPLICATION_PATH")
            .DIRECTORY_SEPARATOR.'configs'
            .DIRECTORY_SEPARATOR.'application.ini';
        $dbconfig = new Zend_Config_Ini($url, "mysql");
        $db = Zend_Db::factory($dbconfig->db);
        $db -> query('SET NAMES UTF8');
        Zend_Db_Table::setDefaultAdapter($db);
    }
}

3.爲每個表格設置一個models

3.1 item表

\htdocs\VoteSys\application\models\item.php

class item extends Zend_Db_Table
{
    protected $_name = 'item';
    protected $_primary = 'id';
}

3.2 vote_log表

class vote_log  extends Zend_Db_Table
{
    protected $_name = 'vote_log';
}

3.3 filter表

class filter extends Zend_Db_Table
{
    protected $_name = 'filter';
}

後臺首頁設置

1.新建後臺控制器

\htdocs\VoteSys\application\controllers\AdminController.php

require_once 'DBController.php';

class AdminController extends DBController
{
    public function indexAction() {
        # code...
    }
}

2.新建後臺首頁視圖

\htdocs\VoteSys\application\views\scripts\admin\index.phtml

<ul>
    <li><a href="/admin/additem">投票</a></li>
    <li><a href="/admin/filter">過濾IP</a></li>
</ul>

後臺添加投票項

1.顯示增加選擇項頁面

\htdocs\VoteSys\application\controllers\AdminController.php添加additemAction

//    增加選擇項頁面
    public function additemAction() {
        # code...
    }

2.添加增加選項頁面視圖

\htdocs\VoteSys\application\views\scripts\admin\additem.phtml

<form action="/admin/additemfunc" method="post">
    <table>
        <tr>
            <td>name</td>
            <td>
                <input type="text" name="name" />
            </td>
        </tr>
        <tr>
            <td>描述</td>
            <td>
                <textarea name="description" cols="30" rows="5"></textarea>
            </td>
        </tr>
        <tr>
            <td>初始化投票數</td>
            <td>
                <input type="text" name="vote_count"></input>
            </td>
        </tr>
        <tr>
            <td>
                <input type="submit" value="Submit"></input>
            </td>
            <td>
                <input type="reset" value="Reset" />
            </td>
        </tr>
    </table>
</form>

3.添加選擇項後臺處理

在AdminController.php內新增additemfuncAction

require_once APPLICATION_PATH.'/models/item.php';
//    完成添加任務
    public function additemfuncAction() {
        //獲取用戶輸入內容
        $name = $this->getRequest()->getParam('name');
        $description = $this->getRequest()->getParam('description');
        $vote_count = $this->getRequest()->getParam('vote_count');
        $data = array(
            'name' => $name,
            'description' => $description,
            'vote_count' => $vote_count
        );
        //創建一個表格模型
        $itemModel = new item();
        $itemModel -> insert($data);
        //頁面跳轉
        $this->render('success');
    }

4.添加成功視圖

\htdocs\VoteSys\application\views\scripts\admin\success.phtml

<script type="text/javascript">
    alert('success!');
    history.back();
</script>

過濾IP設置

1.添加過濾頁面

AdminController.php內添加

//    過濾頁面
    public function filterAction() {
        # code...
    }

2.新建過濾頁面視圖

\htdocs\VoteSys\application\views\scripts\admin\filter.phtml

<form action="/admin/filterfunc" method="post">
    <table>
        <tr>
            <td>IP</td>
            <td>
                <input type="text" name="ip" />
            </td>
        </tr>
        <tr>
            <td>
                <input type="submit" value="Submit"></input>
            </td>
            <td>
                <input type="reset" value="Reset" />
            </td>
        </tr>
    </table>
</form>

3.過濾處理

AdminController.php內添加

require_once APPLICATION_PATH.'/models/filter.php';
//    完成過濾任務
    public function filterfuncAction() {
        //獲取用戶輸入信息
        $ip = $this->getRequest()->getParam('ip');
        $data = array(
            'ip' => $ip
        );
        //創建一個表模型
        $filterModel = new filter();
        //全局頁面跳轉
        if ($filterModel->insert($data) > 0) {
            //成功 跳轉全局視圖
            //挑戰至GlobalController內地okAction 對應視圖
            $this->view->info = "IP $ip 過濾成功";
            $this->forward('ok', 'Global');
        } else {
            //失敗
            $this->view->info = "IP $ip 過濾失敗";
            $this->forward('error', 'Global');
        }
    }

4.全局反饋

1.建立全局控制器

\htdocs\VoteSys\application\controllers\GlobalController.php

class GlobalController extends Zend_Controller_Action
{
    //跳轉ok界面
    public function okAction() {
    }
    //失敗error界面
    public function errorAction() {
    }
}

2.建立全局視圖

新建
\htdocs\VoteSys\application\views\scripts\global

1.成功視圖

新建
\htdocs\VoteSys\application\views\scripts\global\ok.phtml

<script type="text/javascript">
    alert('<?php echo $this->info; ?>');
    history.back();
    //返回並刷新
  //window.location.href="/index/index";
</script>

2.失敗視圖

新建
\htdocs\VoteSys\application\views\scripts\global\error.phtml

<script type="text/javascript">
    alert('<?php echo $this->info; ?>');
    history.back();
</script>

前臺控制

1.前臺首頁顯示

require_once 'DBController.php';
require_once APPLICATION_PATH.'/models/item.php';

class IndexController extends DBController
{
    public function indexAction()
    {
        // 創建表模型
        $itemModel = new item();
        $items = $itemModel->fetchAll()->toArray();
        $this->view->items = $items;
    }
}

2.添加首頁視圖

\htdocs\VoteSys\application\views\scripts\index\index.phtml

<table width="500px" align="center">
    <tr bgcolor="#deb887" align="center">
        <td>名稱</td>
        <td>描述</td>
        <td>票數</td>
        <td>投票</td>
    </tr>
    <?php foreach ($this->items as $item) {?>
        <tr align="center">
            <?php echo "<td>".$item['name']."</td>
            <td>".$item['description']."</td>
            <td>".$item['vote_count']."</td>";?>
            <td>
                <a href="/vote/vote?id=<?php echo $item['id']; ?>">
                    投票
