PHP开源开发框架ZendFramework使用中常见问题说明及解决方案

MVC 代码书写:
控制器代码书写:

复制代码 代码如下:
<?php
class IndexController extends Zend_Controller_Action
{
function init()
{
$this->registry = Zend_Registry::getInstance();
$this->view = $this->registry["view"];
$this->view->baseUrl = $this->_request->getBaseUrl();

}
function indexAction()
{
$this->view->word=" I love spurs";

echo $this->view->render("index.html");

}
function addAction(){
//如果是POST过来的值.就增加.否则就显示增加页面


}
}
?>

控制当中写内容:

复制代码 代码如下:
$this->view->word="ggg";
$this->view->render("index.html");
---->index.html echo $this->word;

application->config.ini
[general]
db.adapter=PDO_MYSQL
db.config.host=localhost
db.config.username=root
db.config.password=
db.config.dbname=think_zw

配置文件引入到framework里面去

复制代码 代码如下:
//配置数据库参数,并连接数据库
$config=new Zend_Config_Ini("./application/config/config.ini",null, true);
Zend_Registry::set("config",$config);
$dbAdapter=Zend_Db::factory($config->general->db->adapter,$config->general->db->config->toArray());
$dbAdapter->query("SET NAMES UTF8");
Zend_Db_Table::setDefaultAdapter($dbAdapter);
Zend_Registry::set("dbAdapter",$dbAdapter);

单一入口模式:localhost/index/add/访问index模块下的add方法
function addAction(){}(在IndexController.php)
默认访问为index模块下的index方法

再建立一个模块model里面的message.php

复制代码 代码如下:
<?php
class Message extends Zend_Db_Table
{
protected $_name ="message";
protected $_primary = "id";
}
?>

模块实例化:

复制代码 代码如下:
function indexAction()
{
$message=new message();//实例化数据库类

//获取数据库内容
$this->view->messages=$message->fetchAll()->toArray();

echo $this->view->render("index.phtml");//显示模版
}

<?foreach($this->messages as $message): ?>
<tr>
<th><?php echo $message["title"]; ?></th>
<td><?php echo $message["content"]; ?></td>
</tr>
<?endforeach; ?>

*************
修改和删除数据

复制代码 代码如下:
<?php if(2==2):?>
kk
<?php else:?>
ll
<?php endif;?>

index.phtml里面加上

复制代码 代码如下:
<a href="<?php echo $this->baseUrl?>/index/exit">编辑</a>
<a href="<?php echo $this->baseUrl?>/index/delete">删除</a>

添加一个新的方法:edit.phtml

复制代码 代码如下:
function editAction(){

$message = new Message();
$db = $message->getAdapter();

if(strtolower($_SERVER["REQUEST_METHOD"])=="post"){
$id = $this->_request->getPost("id");
$cid = $this->_request->getPost("cid");
$title = $this->_request->getPost("title");

$set = array(
"cid"=>$cid,
"title"=>$title
);
$where = $db->quoteInto("id = ?",$id);
//更新数据
$message->update($set,$where);
unset($set);
echo "修改数据成功!<a href="".$this->view->baseUrl."/index/index/">返回</a>";
}else{
$id = $this->_request->getParam("id");
$this->view->messages = $message->fetchAll("id=".$id)->toArray();
echo $this->view->render("edit.phtml");
}
}


function delAction(){
$message = new Message();
$id = (int)$this->_request->getParam("id");

if($id > 0){
$where = "id = " . $id;
$message->delete($where);
}
echo "删除数据成功!<a href="".$this->view->baseUrl."/index/index/">返回</a>";
}

异常出现:

复制代码 代码如下:
Fatal error: Uncaught exception "Zend_Controller_Dispatcher_Exception" with message "Invalid controller specified (index.php)" in

解决办法:在index.php中的

复制代码 代码如下:
$frontController =Zend_Controller_Front::getInstance();后加上
$frontController->setParam("useDefaultControllerAlways", true);

*******
id/3 等于以前的?id=3
