ZendFrameWork1.11.10（MVC部分）学习笔记（2）-阿里云开发者社区

下面建立数据驱动的MVC应用。基本页面如ZendFrameWork1.11.10（MVC部分）学习笔记（1）建立。

首先对页面进行优化，建立css控制页面。

修改ZendApp\application\layouts\layout.phtml

!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
head>
meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
title>
?php echo $this->escape($this->title); ?>
/title>
link rel="stylesheet" type="text/css" media="screen" href="<?php echo $this->baseUrl();?>/public/css/site.css"/>
/head>
body>
div id="content">
?php echo $this->layout()->content; ?>
div>/body>
/html>

由于路径问题，需要取得基本路径：

ZendApp\application\views\helpers\BaseUrl.php

?php
class Zend_View_Helper_BaseUrl
{
function baseUrl()
{
$fc = Zend_Controller_Front::getInstance();
return $fc->getBaseUrl();
}
}

创建css文件。

ZendApp\public\css\site.css

body,html{
margin:0.5px;
font-family: Verdana,sans-serif;
}
h1{
font-size:1.4em;
color: #008000;
}
a {
color:#008000;
}
/* Table */
th {
text-align:left;
}
td,th{
padding-right:5px;
}
/* style form */
form dt {
width:100px;
display: block;
float: left;
clear: left;
}
form dd{
margin-left:0;
float: left;
}
form #submitbutton{
margin-left: 100px;
}

在mysql的数据库中创建表并创建测试数据：

CREATE TABLE albums (
id int(11) NOT NULL auto_increment,
artist varchar(100) NOT NULL,
title varchar(100) NOT NULL,
PRIMARY KEY (id)
);
INSERT INTO albums (artist, title)
VALUES
('Duffy', 'Rockferry'),
('Van Morrison', 'Keep It Simple');

配置数据库链接

ZendApp\application\config.ini

[general]
db.adapter = PDO_MYSQL
db.params.host = localhost
db.params.username = root
db.params.password = root
db.params.dbname = wangcc

其中＝右边的值修改为你自己的值。

修改index.php加载数据库：

ZendApp\index.php

?php
error_reporting(E_ALL|E_STRICT);
ini_set('display_errors', 1);
date_default_timezone_set('Europe/London');
// 目录设置和类装载
set_include_path('.' . PATH_SEPARATOR . './library/'
. PATH_SEPARATOR . './application/models'
. PATH_SEPARATOR . get_include_path());
// include "Zend/Loader.php";
// Zend_Loader::registerAutoload();
require_once 'Zend/Loader/Autoloader.php';
Zend_Loader_Autoloader::getInstance()->setFallbackAutoloader(true);
// Load configuration
$config = new Zend_Config_Ini("./application/config.ini","general");
$registry = Zend_Registry::getInstance();
$registry->set('config',$config);
// Setup Database
$db = Zend_Db::factory($config->db);
Zend_Db_Table::setDefaultAdapter($db);
// 设置控制器
$frontController = Zend_Controller_Front::getInstance();
$frontController->setParam('useDefaultControllerAlways', true);
//$frontController->setBaseUrl('/ZendApp');
$frontController->throwExceptions(true);
$frontController->setControllerDirectory('./application/controllers');
Zend_Layout::startMvc(array('layoutPath'=>'./application/layouts'));
// run!
$frontController->dispatch();

创建模型和form

ZendApp\application\models\Albums.php

?php
class Albums extends Zend_Db_Table
{
protected $_name = 'albums';
}
?>

ZendApp\application\models\AlbumForm.php

?php
class AlbumForm extends Zend_Form
{
public function __construct($options = null)
{
parent::__construct($options);
$this->setName('album');
$id = new Zend_Form_Element_Hidden('id');
$artist = new Zend_Form_Element_Text('artist');
$artist->setLabel('Artist')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$title = new Zend_Form_Element_Text('title');
$title->setLabel('Title')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');
$submit = new Zend_Form_Element_Submit('submit');
$submit->setAttrib('id', 'submitbutton');
$this->addElements(array($id, $artist, $title, $submit));
}
}
?>

修改控制器和views

ZendApp\application\controllers\IndexController.php

?php
class IndexController extends Zend_Controller_Action
{
function indexAction()
{
$this->view->title="My Albums";
$albums = new Albums();
$this->view->albums = $albums->fetchAll();
}
function addAction()
{
$this->view->title="Add New Albums";
$form = new AlbumForm();
$form->submit->setLabel('Add');
$this->view->form = $form;
if ($this->_request->isPost()) {
$formData = $this->_request->getPost();
if ($form->isValid($formData)) {
$albums = new Albums();
$row = $albums->createRow();
$row->artist = $form->getValue('artist');
$row->title = $form->getValue('title');
$row->save();
$this->_redirect('/');
} else {
$form->populate($formData);
}
}
}
function editAction()
{
$this->view->title="Edit Albums";
$form = new AlbumForm();
$form->submit->setLabel('Save');
$this->view->form = $form;
if ($this->_request->isPost()) {
$formData = $this->_request->getPost();
if ($form->isValid($formData)) {
$albums = new Albums();
$id = (int)$form->getValue('id');
$row = $albums->fetchRow('id='.$id);
$row->artist = $form->getValue('artist');
$row->title = $form->getValue('title');
$row->save();
$this->_redirect('/');
} else {
$form->populate($formData);
}
} else {
// album id is expected in $params['id']
$id = (int)$this->_request->getParam('id', 0);
if ($id > 0) {
$albums = new Albums();
$album = $albums->fetchRow('id='.$id);
$form->populate($album->toArray());
}
}
}
function deleteAction()
{
$this->view->title="Delete Albums";
if ($this->_request->isPost()) {
$id = (int)$this->_request->getPost('id');
$del = $this->_request->getPost('del');
if ($del == 'Yes' && $id > 0) {
$albums = new Albums();
$where = 'id = ' . $id;
$albums->delete($where);
}
$this->_redirect('/');
} else {
$id = (int)$this->_request->getParam('id');
if ($id > 0) {
$albums = new Albums();
$this->view->album = $albums->fetchRow('id='.$id);
}
}
}
}

ZendApp\application\views\scripts\index\add.phtml

html>

?php echo $this->escape($this->title);?>

form action="<?php echo $this->url(array('action'=>'delete')); ?>"
method="post">

input type="submit" name="del" value="No" />/div>
/form>
?php else: ?>
p>Cannot find album. /p>
?php endif;?>
/body>
/html>

ZendApp\application\views\scripts\index\edit.phtml

?php echo $this->escape($this->title);?>

?php foreach($this->albums as $album) : ?>

a href="<?php echo $this->url(array('controller'=>'index', 'action'=>'edit', 'id'=>$album->id));?>">Edit /a>

?php endforeach; ?>

这样我们就建立了一个数据驱动的ZendFramework的MVC应用。
