1. First, let's set up our program so that Zend can automatically load the method without manual loading.

The Code is as follows:

Require_once 'zend/Loader/Autoloader. php' // load the automatic loading class
$ Loader = Zend_Loader_Autoloader: getInstance (); // automatically instantiate
$ Loader-> registerNamespace ('application _ '); // register the namespace (only the default and registered namespaces can be automatically loaded)
$ Loader-> registerNamespace (array ('foo _ ', 'bar _'); // register multiple namespaces
$ Loader-> setFallbackAutoloader (true); // a method that increases consumption. It does not require namespaces, virtual hosts, and directly loads all classes (not recommended)

Then pay attention to whether your include directory already contains your own directory to be loaded

The Code is as follows:

Set_include_path (implode (PATH_SEPARATOR, array (
Realpath (APPLICATION_PATH. '/../library '),
Realpath (APPLICATION_PATH. '/forms /'),
Get_include_path (),
)));
// Here we include our forms directory to facilitate program loading

2. Check the form directory.
Create a Guestbook. phps under application/forms/
As a form class file, it is as follows:

The Code is as follows:

Class Application_Form_Guestbook extends Zend_Form
{
Public function init ()
{
// Set the method for the display form to POST
$ This-> setMethod ('post'); // you can specify the submission method.

// Add an email element
$ This-> addElement ('text', 'email ', array (// original type, term, Hong Kong Vm, and definition of some other information
'Label' => 'your email address :',
'Requestred' => true,
'Filters '=> array ('stringtrim '),
'Validatator' => array (
'Emailaddress ',
)
));

// Add the comment element
$ This-> addElement ('textea ', 'comment', array (
'Label' => 'Please Comment :',
'Requestred' => true,
'Validatator' => array (
Array ('validator' => 'stringlength', 'options' => array (0, 20 ))
)
));

// Add a captcha
$ This-> addElement ('captcha ', 'captcha', array (
'Label' => 'Please enter the 5 letters displayed below :',
'Requestred' => true,
'Captcha '=> array (
'Captcha '=> 'figlet ',
'Wordlen' => 5,
'Timeout' = & gt; 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,
));
}
}

Then add a route control file
Applictaion/controller/GuestbookController. php

The Code is as follows:

Class GuestbookController extends Zend_Controller_Action
{
// Snipping indexAction ()...
Public function signAction ()
{
$ Request = $ this-> getRequest (); // obtain the received information
// Include_once ("../application/forms/Guestbook. php"); manually load the class. Only when the class cannot be automatically loaded will the website space be required
$ Form = new Application_Form_Guestbook; // instantiate this method

If ($ this-> getRequest ()-> isPost () {// if the result is passed by POST
If ($ form-> isValid ($ request-> getPost () {// determines whether the pass is valid
$ Comment = new Application_Model_Guestbook ($ form-> getValues ());
$ Mapper = new Application_Model_GuestbookMapper ();
$ Mapper-> save ($ comment );
Return $ this-> _ helper-> redirector ('index ');
}
}

$ This-> view-> form = $ form; // assign a value to an attempt
}
}

Add a simple sign View File:
Address: application/views/scripts/guestbook/sgin. php

The Code is as follows:

Please use the form below to sign our guestbook!
$ This-> form-> setAction ($ this-> url ());
Echo $ this-> form;
