Zend framework generates verification code and implements verification code verification function (with demo source download), Zenddemo

This paper describes the method of Zend Framework to generate verification code and implement verification code verification function. Share to everyone for your reference, as follows:

Today's how to implement the verification code in the message of the function. This will help our site to reduce some spam or advertising messages. In this is the Zend_captcha component I have not applied to the Zend Framework. I just found thinkphp in the framework of the Verification code class. And I put it in the. We leave a message on the implementation of this verification code ... I am here.. is to write it in the form of a plugin ... Of course the Zend Framework has many ways to use other code. I will only use one of these now ... So there are good ways to friends. Can be discussed together next. Let's make progress together. Oh....

First step: Find the Library folder in our original tutorial. This is where we stored our Zend Class Library folder. Now let's add a few folders to the Library folder: library/custom/controller/plugin/

Folder we joined to complete. This is where we're going to find our Captcha file. Here I name the imgcode.php file name: This file is the class file that we are going to use to generate the verification code. Of course, this file was rewritten as a plugin form in the Zend Framework ... The imgcode.php section documents are described below:

<?php//imgcode.php part of the program description//program generated verification code Data $randval = $this->rand_string ($length, $mode);//The data stored in the Zend_session ...//There is a Session namespace problem, friends can go to read the manual $authcode = new Zend_session_namespace (' Auth_code '); $authCode->imagecode = $ Randval;? >

Step two: In the controller of our message book (indexcontroller.php), add a following action (action). This action is for the purpose of generating validation.

The program looks like this:

<?phppublic function Imgcodeaction () {$this->getfrontcontroller ()->setparam (' Noviewrenderer ', true);// Call our Verification code class Zend_loader::loadclass (' Custom_controller_plugin_imgcode '); $imagecode =new Custom_controller_plugin_ Imgcode ();//Return Verification Code Picture $imagecode->image2 ();}? >

The third step: in our message template to add the function of verification code: Open the message this Display page template, message/index.phtml we fill in the message area to add the following HTML code. This time please look at the source file inside the JS code. Like to replace the captcha image with what features: I won't say much about this little thing. I just added some JS features to the last tutorial.

At last.. is to find messageaction this function in our controller (indexcontroller.php). We add the ability to use the verification code in the inside. That is, verifying that the user filled out the verification code is the same as the verification code in the session we exist. If the same: We let him leave a message. Otherwise, he will not leave a message. I think we all have the basic idea.
