Use of Yii Verification code and verification process

The use and verification process of Yii Verification code

If you want to implement this process, you need a few steps.

The first step is the controller's operation.

Add the following code to the controller you want to manipulate:

Public function actions () {return array (//CAPTCHA action renders the CAPTCHA image displayed on the contact page ' Captcha ' =>array (' class ' = ' ccaptchaaction ', ' BackColor ' =>0xffffff, ' maxLength ' = ' 8 ',//generate up to a few characters ' minLength ' = > ' 7 ',//at least generate a few characters ' height ' = ' + ', ' width ' = ' 230 ',); }public function Accessrules () {return array (' Allow ', ' actions ' =>array (' captcha '), ' Users ' =>array (' * '), ,);}

　　

The second step is the operation of the view

Add the following code where you want the verification code to appear:

 
  Widget (' Ccaptcha ', Array (' Showrefreshbutton ' =>true, ' clickableimage ' =>false, ' buttonlabel ' = ' refresh Captcha ', ' Imageoptions ' =>array (' alt ' = ' Click to change ', ' title ' = ' Click to change ', ' style ' = ' cursor:pointer ', ' padding ' = ' 10 ')) ;?>

The third step is loginform operation.

 ' Login account cannot be empty '), array (' Password ', ' Required ', ' message ' = ' password cannot be null '), array (' Verifycode ', ' Required ', ' message ' = = ') Verification code cannot be empty '), array (' Verifycode ', ' captcha ', ' on ' = ' login ', ' AllowEmpty ' =>! Yii::app ()->admin->isguest),//RememberMe needs to be a booleanarray (' RememberMe ', ' Boolean '),//password needs to Be Authenticatedarray (' password ', ' Authenticate '),);} /*** declares attribute labels.*/public function Attributelabels () {return array (' rememberme ' = ' next time remember me ', ' Verifycode ' = ' Verification Code ');} /*** authenticates the password.* this is the ' authenticate ' validator as declared in rules (). */public function Authentica Te ($attribute, $params) {if (! $this->haserrors ()) {$this->_identity=new useridentity ($this->username,$ This->password); if (! $this->_identity->authenticate ()) $this->adderror (' Password ', ' Incorrect account or password ');}} Public Function Validateverifycode ($verifyCode) {if (Strtolower ($this->verifycode) = = = Strtolower ($verifyCode)) { return true;} else{$this->adderror (' Verifycode ', ' captcha error. ');}} /Logs in the user using the given username and password in the model.* @return Boolean whether login is Successful*/pub Lic function Login () {if ($this->_identity===null) {$this->_identity=new useridentity ($this->username,$ This->password); $this->_identity->authenticate ();} if ($this->_identity->errorcode===useridentity::error_none) {$duration = $this->rememberme? 3600*24*30:0; /Daysyii::app ()->user->login ($this->_identity, $duration); return true;} Else{return false;}}}

　　

The fourth step, the implementation of the verification process, then the specific view of my own write a way, in the third part has been written well
Validateverifycode, you can call it in the controller.

My call is as follows:

Public Function Actionlogin () {$model =new loginform;if (isset ($_post[' ajax]) && $_post[' Ajax ']=== ' Login-form ') {echo cactiveform::validate ($model); Yii::app ()->end ();} if (Isset ($_post[' LoginForm '))) {$model->attributes=$_post[' loginform '];//validate user input and redirect to the Previous page if Validif ($model->validate () && $model->validateverifycode ($this->createaction (' Captcha ')->getverifycode ()) && $model->login ()) {$this->redirect (' Default /index '));}} $this->render (' login ', array (' model ' = $model));}
