解析在zend Farmework下如何创立一个FORM表单

1.首先让我们设置一下我们的程序，让Zend能够自动载入方法，不需要我们手动的去载入
复制代码 代码如下:
require_once "Zend/Loader/Autoloader.php"    //载入自动加载类
$loader = Zend_Loader_Autoloader::getInstance();//自动实例化
$loader->registerNamespace("Application_");//注册命名空间（只有系统默认的，和注册的才可以被自动载入）
$loader->registerNamespace(array("Foo_", "Bar_")); //多个命名空间的注册方法
$loader->setFallbackAutoloader(true);  //一个增加消耗的方法，不需要命名空间，直接载入所有类(不被推荐使用)

然后请注意，你的包含目录是否已经包含了，你自己的需被载入的目录
复制代码 代码如下:
set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH . "/../library"),
    realpath(APPLICATION_PATH . "/forms/"),
    get_include_path(),
)));
//这里我们包含了我们的forms目录，方便程序的被载入

2.确认下form的目录
在application/forms/下 建立一个  Guestbook.phps
作为我们form的类文件，如下：
复制代码 代码如下:
<?php
 class Application_Form_Guestbook extends Zend_Form
{
    public function init()
    {
        // Set the method for the display form to POST
        $this->setMethod("post");//设置提交方式        // Add an email element
        $this->addElement("text", "email", array(//原件的类型，名词，和一些其他信息的定义
            "label"      => "Your email address:",
            "required"   => true,
            "filters"    => array("StringTrim"),
            "validators" => array(
                "EmailAddress",
            )
        ));        // Add the comment element
        $this->addElement("textarea", "comment", array(
            "label"      => "Please Comment:",
            "required"   => true,
            "validators" => array(
                array("validator" => "StringLength", "options" => array(0, 20))
                )
        ));        // Add a captcha
        $this->addElement("captcha", "captcha", array(
            "label"      => "Please enter the 5 letters displayed below:",
            "required"   => true,
            "captcha"    => array(
                "captcha" => "Figlet",
                "wordLen" => 5,
                "timeout" => 300
            )
        ));        // Add the submit button
        $this->addElement("submit", "submit", array(
            "ignore"   => true,
            "label"    => "Sign Guestbook",
        ));        // And finally add some CSRF protection
        $this->addElement("hash", "csrf", array(
            "ignore" => true,
        ));
    }
}

然后添加一个路由控制文件
applictaion/controller/GuestbookController.php
复制代码 代码如下:
<?php
class GuestbookController extends Zend_Controller_Action
{
    // snipping indexAction()...
    public function signAction()
    {
        $request = $this->getRequest();//获取接受到得信息
       // include_once("../application/forms/Guestbook.php");  手动加载类，只有不能自动载入时，才需要
        $form    = new Application_Form_Guestbook;//实例化这个方法        if ($this->getRequest()->isPost()) {//如果是POST传递的结果
            if ($form->isValid($request->getPost())) {//判断传递是否有效
                $comment = new Application_Model_Guestbook($form->getValues());
                $mapper  = new Application_Model_GuestbookMapper();
                $mapper->save($comment);
                return $this->_helper->redirector("index");
            }
        }        $this->view->form = $form;//将表单赋值给试图
    }
}

最后添加一个简单的sign视图文件即可：
地址：application/views/scripts/guestbook/sgin.php
复制代码 代码如下:
Please use the form below to sign our guestbook!
<?php
$this->form->setAction($this->url());
echo $this->form;
