一个使用Zend framework 1.9写的简单博客程序
我曾用Zend framework 1.8工作，现在用1.9。我做了一个简单的博客程序。我说的博客就是类似Wordpress的东西，可以发文章、加评论，现在还能从Picasa上抓相册。
我是一个Zend framework和MVC的新手，我知道里面有些错误，有一些是我图方便而产生的。同时我也是单元测试的新手，所以里面没有写什么测试数据代码。抱歉。我知道这个程序的缺点，数据库也不太好。但我还是把它发布了，希望能帮助一些人理解Zend_ACL、Zend_Auth、Zend_Form等。我在里面还加了一个图片集功能，用到了Zend_Gdata接口，可以从Picasa读取照片和相册，未来我考虑通过管理界面来增加照片，以及在管理界面做一些特色，如果我有时间的话。
我看过各式各样的博客程序，有些已经过时了，但有些仍然生机勃勃。我在用Zend Toolkit，因为相比图形界面，我更喜欢使用命令行。我提供了完整的Zend framework 1.9博客程序例的下载链接，大家可以在文末的链接处下载。
开发环境：
1）LAMP或WAMP或MAMP
2）配置好的Zendframework 1.9
3）我用eclipse、netbeans或zend studio i5编辑，如果你用zend studio i5，就不用看下面命令行的部分，许多东西已经在里面有了。
我希望你已经配置好了ZF，现在让我们用命令行来创建项目、控制器和动作。符号$代表命令行。（ZF Dream翻译）
这就创建了ZF 1.8+的目录结构。切换到项目所在目录，如cd <项目名称>。输入命令：
ProjectDirectory
ProjectProfileFile
ApplicationDirectory
ConfigsDirectory
ApplicationConfigFile
ControllersDirectory
ControllerFile
ActionMethod
ControllerFile
ModelsDirectory
ViewsDirectory
ViewScriptsDirectory
ViewControllerScriptsDirectory
ViewScriptFile
ViewControllerScriptsDirectory
ViewScriptFile
ViewHelpersDirectory
BootstrapFile
LibraryDirectory
PublicDirectory
PublicIndexFile
HtaccessFile
TestsDirectory
TestPHPUnitConfigFile
TestApplicationDirectory
TestApplicationBootstrapFile
TestLibraryDirectory
TestLibraryBootstrapFile
上面就是显示的目录结构。下面我们来创建控制器和动作：
Creating a controller at //var/www/blog/application/controllers/PostsController.php
Creating an index action method in controller posts
Creating a view script for the index action method at //var/www/blog/application/views/scripts/posts/index.phtml
Creating a controller test file at //var/www/blog/tests/application/controllers/PostsControllerTest.php
Updating project profile '//var/www/blog/.zfproject.xml'
Creating an action named view inside controller at //var/www/blog/application/controllers/PostsController.php
Updating project profile '//var/www/blog/.zfproject.xml'
Creating a view script for the view action method at //var/www/blog/application/views/scripts/posts/view.phtml
Updating project profile '//var/www/blog/.zfproject.xml'
Creating an action named edit inside controller at //var/www/blog/application/controllers/PostsController.php
Updating project profile '//var/www/blog/.zfproject.xml'
Creating a view script for the edit action method at //var/www/blog/application/views/scripts/posts/edit.phtml
Updating project profile '//var/www/blog/.zfproject.xml'
Creating an action named add inside controller at //var/www/blog/application/controllers/PostsController.php
Updating project profile '//var/www/blog/.zfproject.xml'

Updating project profile '//var/www/blog/.zfproject.xml'
Creating a view script for the login action method at //var/www/blog/application/views/scripts/index/login.phtml
Updating project profile '//var/www/blog/.zfproject.xml'
Creating an action named logout inside controller at //var/www/blog/application/controllers/IndexController.php
Updating project profile '//var/www/blog/.zfproject.xml'
Creating a view script for the logout action method at //var/www/blog/application/views/scripts/index/logout.phtml
Updating project profile '//var/www/blog/.zfproject.xml'
建立数据库，并添加用户表、评论表和文章表。
`id` int(11) NOT NULL AUTO_INCREMENT,
`Post_id` int(11) NOT NULL,
`Description` varchar(300) NOT NULL,
`Name` varchar(200) NOT NULL,
`Email` varchar(250) NOT NULL,
`Webpage` varchar(200) NOT NULL,
`Postedon` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
`id` int(11) NOT NULL AUTO_INCREMENT,
`Title` varchar(250) NOT NULL,
`Description` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
`id` int(11) NOT NULL AUTO_INCREMENT,
`Username` varchar(200) NOT NULL,
`Password` varchar(250) NOT NULL,
`Role` varchar(10) NOT NULL,
`Name` varchar(200) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
在Bootstrap.php增加如下代码，这样你就可以象__autoload()一样自动加载类。（ZF Dream翻译）
protected function _initAutoload()
{
$moduleLoader = new Zend_Application_Module_Autoloader(array(
'namespace' => '',
'basePath' => APPLICATION_PATH));
return $moduleLoader;
}
在application/configs/application.ini中加上布局和数据库连接信息。完整代码如下：
[production] phpSettings.display_startup_errors = 0 phpSettings.display_errors = 0 includePaths.library = APPLICATION_PATH "/../library" bootstrap.path = APPLICATION_PATH "/Bootstrap.php" bootstrap.class = "Bootstrap" resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers" resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts" resources.view[] = resources.db.adapter = PDO_MYSQL resources.db.params.host = localhost resources.db.params.username = root resources.db.params.password = resources.db.params.dbname = hari_zendblog [staging : production] [testing : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 [development : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1
编写布局文件：
application/layouts/scripts/layout.phtml
<?php
echo $this->doctype() ?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Bloggers turns to developers</title>
<?php echo $this->headLink()->appendStylesheet('/quickstart/public/css/global.css') ?>
<?php echo $this->headLink()->prependStylesheet($this->baseUrl().'/css/main.css'); ?>
</head>
<body>
<div id="header" style="background-color: #EEEEEE; height: 30px;">
<div id="header-logo" style="float: left">
<b><a href="<?php echo $this->baseurl(); ?>">ZF Quickstart Application</a></b>
<a href="<?php
if( Zend_Auth::getInstance()->hasIdentity() ) {
$str = "/index/logout";
$log = "Logout";
} else {
$str = "/index/login";
$log = "Login";
}
echo $this->baseurl().$str; ?>"><?php echo $log; ?></a>
</div>
</div>
<div><?php echo $this->layout()->content ?></div>
</body>
</html>
你可以通过phpmyadmin或其他方式插入一些一些测试数据，这样前端就能显示出一些文章来。把下面的代码加到IndexController的indexAction中去：（ZF Dream翻译）
public function indexAction()
{
// action body
$posts = new Model_DbTable_Posts();
$result = $posts->getPosts();
/* 下面是分页代码 */
$page = $this->_getParam('page',1);
$paginator = Zend_Paginator::factory($result);
$paginator->setItemCountPerPage(2);
/* 每页的文章数。我写成2这样你可以容易得看到分页效果. */
$paginator->setCurrentPageNumber($page);
$this->view->paginator = $paginator;
}
以下是完整的IndexController.php代码：
<?php
class IndexController extends Zend_Controller_Action
{
public function init()
{
/* Initialize action controller here */
}
public function indexAction()
{
// action body
$posts = new Model_DbTable_Posts();
$result = $posts->getPosts();
$page = $this->_getParam('page',1);
$paginator = Zend_Paginator::factory($result);
$paginator->setItemCountPerPage(2);
$paginator->setCurrentPageNumber($page);
$this->view->paginator = $paginator;
}
public function loginAction()
{
$loginForm = new Form_Login();
$redirect = $this->getRequest()->getParam('redirect', 'index/index');
$loginForm->setAttrib('redirect', $redirect );
$auth = Zend_Auth::getInstance();
if(Zend_Auth::getInstance()->hasIdentity()) {
$this->_redirect('/index/hello');
} else if ($this->getRequest()->isPost()) {
if ( $loginForm->isValid($this->getRequest()->getPost()) ) {
$username = $this->getRequest()->getPost('username');
$pwd = $this->getRequest()->getPost('pass');
$authAdapter = new Model_AuthAdapter($username, $pwd);
$result = $auth->authenticate($authAdapter);
if(!$result->isValid()) {
switch ($result->getCode()) {
case Zend_Auth_Result::FAILURE_CREDENTIAL_INVALID:
$this->view->error = 'user credentials not found';
}
} else {
//Successfully logged in
$this->_redirect( $redirect );
}
}
}
$this->view->loginForm = $loginForm;
// $this->_redirect($redirectUrl);
}
public function logoutAction()
{
$auth = Zend_Auth::getInstance();
$auth->clearIdentity();
$this->_redirect('/');
}
}
现在你需要创建一个文章表的连接，以便我们来做插入和更改操作。这部分内容写到application/Models/DbTable/Posts.php里去。
<?php
class Model_DbTable_Posts extends Zend_Db_Table_Abstract
{
protected $_name = 'posts';
public function getPosts()
{
$orderby = array('id DESC');
$result = $this->fetchAll('1', $orderby );
return $result->toArray();
}
public function getPost( $id )
{
$id = (int)$id;
$row = $this->fetchRow('id = ' . $id);
if (!$row) {
throw new Exception("Count not find row $id");
}
return $row->toArray();
}
/*
* Add new posts
*/
public function savePost( $post )
{
$data = array( 'Title'=> $post['Title'],
'Description'=> $post['Description']);
$this->insert($data);
}
/*
* Update old posts
*/
public function updatePost( $post )
{
$data = array(
'id'=> $post['id'],
'Title'=> $post['Title'],
'Description'=> $post['Description']);
$where = 'id = '.$post['id'];
$this->update($data , $where );
}
}
创建application/Models/DbTable/Users.php：
<?php
class Model_DbTable_Users extends Zend_Db_Table_Abstract
{
protected $_name = 'users';
public function findCredentials($username, $pwd)
{
$select = $this->select()->where('username = ?', $username)
->where('password = ?', $this->hashPassword($pwd));
$row = $this->fetchRow($select);
if($row) {
return $row;
}
return false;
}
protected function hashPassword($pwd)
{
return md5($pwd);
}
}
创建application/Models/DbTable/Comments.php：
<?php
class Model_DbTable_Comments extends Zend_Db_Table_Abstract
{
protected $_name = 'comments';
public function getComments( $postid )
{
$result = $this->fetchAll( "post_id = '$postid'" );
return $result->toArray();
}
public function saveComment( $commentForm )
{
$data = array('post_id' => $commentForm['id'] ,
'Description' => $commentForm['comment'],
'Name' => $commentForm['name'],
'Email' => $commentForm['email'],
'Webpage' => $commentForm['webpage'] );
$this->insert($data);
}
}
现在我们来建立登录表单/application/forms/Login.php：（ZF Dream翻译）
<?php
class Form_Login extends Zend_Form
{
public function __construct()
{
parent::__construct($options);
$this->setName('UserLogin');
$username = new Zend_Form_Element_Text('username');
$username->setLabel('User Name')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$pass = new Zend_Form_Element_Password('pass');
$pass->setLabel('Password')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$submit = new Zend_Form_Element_Submit('submit');
$redirect = new Zend_Form_Element_Hidden('redirect');
$submit->setAttrib('id', 'submitbutton');
$this->addElements( array ( $username, $pass, $submit));
}
}
创建一个表单，用于发文章：
application/forms/posts.php
<?php
class Form_Post extends Zend_Form
{
public function __construct()
{
parent::__construct($options);
$this->setName('Posts');
$id = new Zend_Form_Element_Hidden('id');
$title = new Zend_Form_Element_Text('Title');
$title->setLabel('Title')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$description = new Zend_Form_Element_Textarea('Description');
$description->setLabel('Description')
->setRequired(true)
->setAttrib('rows',20)
->setAttrib('cols',50)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$submit = new Zend_Form_Element_Submit('submit');
$submit->setAttrib('id', 'submitbutton');
$this->addElements( array( $id, $title, $description, $submit ));
}
}
创建一个表单，用于发评论：（ZF Dream翻译）
application/forms/Comments.php
<?php
class Form_Comments extends Zend_Form
{
public function __construct()
{
$acl = new Model_Acl();
$identity = Zend_Auth::getInstance()->getIdentity();
/*
* 检查是否允许发评论
*/
if( Zend_Auth::getInstance()->hasIdentity()
&& $acl->isAllowed( $identity['role'] ,'comments','add') ) {
parent::__construct($options);
$this->setName('Comments');
$id = new Zend_Form_Element_Hidden('id');
$name = new Zend_Form_Element_Text('name');
$name->setLabel('Your Name')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$email = new Zend_Form_Element_Text('email');
$email->setLabel('Email')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$webpage = new Zend_Form_Element_Text('webpage');
$webpage->setLabel('Webpage')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$comment = new Zend_Form_Element_Textarea('comment');
$comment->setLabel('Comments')
->setRequired(true)
->setAttrib('rows',7)
->setAttrib('cols',30)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$submit = new Zend_Form_Element_Submit('submit');
$submit->setAttrib('id', 'submitbutton');
$this->addElements( array ($id, $name, $email, $webpage, $comment, $submit));
}
}
}
创建application/Models/Acl.php
<?php
class Model_Acl extends Zend_Acl
{
public function __construct()
{
/*
* 增加一个新角色"guest"
* Guest能浏览所有内容
*/
$this->addRole(new Zend_Acl_Role('guest'));
/*
* 增加user角色继承guest
* Users能发评论
*/
$this->addRole(new Zend_Acl_Role('user'), 'guest');
/*
* 增加blogger角色继承ueser
* Bloggers能发文章
*/
$this->addRole(new Zend_Acl_Role('blogger'), 'user');
/*
* 增加admin角色继承blogger
* 拥有所有的权利
*/
$this->addRole(new Zend_Acl_Role('admin'), 'blogger');
//增加posts资源
$this->add(new Zend_Acl_Resource('posts'));
//增加edit资源，继承posts
//$this->add(new Zend_Acl_Resource('edit'), 'posts');
//增加edit资源
//$this->add(new Zend_Acl_Resource('add'), 'posts');
//最后，我们让guest可以浏览所有的内容
$this->allow('guest', 'posts', 'view');
// Bloggers能发文章，修改文章
$this->allow('blogger', 'posts', 'edit');
$this->allow('blogger', 'posts', 'add');
}
}
创建application/Models/AuthAdapter.php
<?php
class Model_AuthAdapter implements Zend_Auth_Adapter_Interface
{
protected $username;
protected $password;
protected $user;
public function __construct($username, $password) {
$this->username = $username;
$this->password = $password;
$this->user = new Model_DbTable_Users();
}
public function authenticate()
{
$match = $this->user->findCredentials($this->username, $this->password);
//var_dump($match);
if(!$match) {
$result = new Zend_Auth_Result(Zend_Auth_Result::FAILURE_CREDENTIAL_INVALID, null);
} else {
$user = current($match);
$result = new Zend_Auth_Result(Zend_Auth_Result::SUCCESS, $user);
}
return $result;
}
}
创建application/views/helpers/BaseUrl.php
<?php
class Zend_View_Helper_BaseUrl {
function baseUrl() {
$fc = Zend_Controller_Front::getInstance();
return $fc->getBaseUrl();
}
}
?>
创建application/views/helpers/LinkTo.php
<?php
class Zend_View_Helper_LinkTo
{
protected static $baseUrl = null;
public function linkTo($path)
{
if (self::$baseUrl === null) {
$request = Zend_Controller_Front::getInstance()->getRequest();
$root = '/' . trim($request->getBaseUrl(), '/');
if ($root == '/') {
$root = '';
}
self::$baseUrl = $root . '/';
}
return self::$baseUrl . ltrim($path, '/');
}
}
创建application/views/helpers/LoggedInUser.php
<?php
class Zend_View_Helper_LoggedInUser
{
protected $_view;
function setView($view)
{
$this->_view = $view;
}
function loggedInUser()
{
$auth = Zend_Auth::getInstance();
if($auth->hasIdentity())
{
$logoutUrl = $this->_view->linkTo('auth/logout');
$user = $auth->getIdentity();
$username = $this->_view->escape(ucfirst($user->username));
$string = 'Logged in as ' . $username . ' | <a href="' .
$logoutUrl . '">Log out</a>';
} else {
$loginUrl = $this->_view->linkTo('auth/identify');
$string = '<a href="'. $loginUrl . '">Log in</a>';
}
return $string;
}
}
用下面的内容来替换掉默认的application/views/scripts/index/index.phtml：
<?php if (count($this->paginator)): ?>
<?php foreach ($this->paginator as $post ): ?>
<div class="post">
<div class="title"><a href="<?php echo $this->baseUrl()."/posts/view/id/".$post['id']; ?>"><?php echo $this->escape($post['Title']); ?></a></div>
<div class="description"><?php echo nl2br(substr( strip_tags( $post['Description']), 0 , 300)); ?></div>
<div class="commentscount">Comments( count )</div>
</div>
<?php endforeach; ?>
<?php endif; ?>
<div class="pagination"><?php echo $this->paginationControl($this->paginator,
'Sliding',
'/partials/my_pagination_control.phtml'); ?></div>
用下面的内容来替换application/views/scripts/index/login.phtml
<?php echo $this->errors; ?> <?php echo $this->loginForm; ?>
用下面的内容来替换application/views/scripts/index/logout.phtml
<div>Successfully Logged out</div>
创建application/views/scripts/partials/my_pagination_control.phtml（你可以在不同的目录里放占位符，我忘记替换了。）（ZF Dream翻译）
<?php if ($this->pageCount): ?>
<div class="paginationControl">

我希望我没漏掉什么。如果有什么错误请通知我。你可以从git获得一个工作副本。我参考了超过50个博客程序。学Zend Framework的同时我还做过一个自定义搜索引擎。我之前的文章里发过。
感谢各位，我希望你们喜欢我的小博客。如果有那里不清楚，请告诉我。你可以发邮件给我，当然最好就在下面发表评论，你可以从http://github.com/harikt/zendblog获得一份代码，而且要象http://zendcasts.com的Jon Lembord一般大言不惭地说：谢谢github和git提供这样精彩的东东。
