解析在zend Farmework下如何创立一个FORM表单_php技巧
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
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:
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
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
Please use the form below to sign our guestbook!
$this->form->setAction($this->url());
echo $this->form;
