yii2框架-yii2的rules验证(七)

yii2的验证规则是一个非常实用而且高效安全的验证功能，下面是我自己的一些总结
在一个model里，继承ActiveRecord,重写覆盖原来的rules(),同时可以 启动场景的功能,重新覆盖scenarios()函数

model模型User.php：

namespace appmodels;
use Yii;
use yiiwebIdentityInterface;
use yiidbActiveRecord;
use yiicaptchaCaptcha;

class User extends ActiveRecord {

	//定义好属性，因为在mysql的表里没有这些字段，所以需要用到就得自定义
	//整个model的属性，其实还包括mysql的字段，ActiveRecord已经帮我们完成，所以无需定义
	public $verifyCode;
    public $password_compare;

     /**
     * @inheritdoc
    */
    public function rules()
    {
        return [
            //注册时必须字段，在register，和savede场景中都必须要
            [["useraccount", "username", "password"],"required","on"=>["register","save"]],

            //任何场景都需要验证
            ["useraccount","string","length" =>[7,12]],

            /**验证是否唯一，即用户名是否已注册，在save场景中，这个动作由前端表单的设置"enableAjaxValidation"=>true来ajax异步触发，在控制器的save中要执行以下的代码：
            	$model->load($_POST);

		  if (Yii::$app->request->isAjax) {

		   	Yii::$app->response->format = yiiwebResponse::FORMAT_JSON;

		   	return yiiootstrapActiveForm::validate($model); 
		  }
            */
            ["useraccount", "unique", "targetClass"=>self::className(), "message" => "此用户名已经被使用","on"=>"save"],


            //登录时字段必须
            [["useraccount","password"],"required","on"=>["login","dologin"]],


            //密码验证，内联validatePassword的函数名进行验证
            ["password","validatePassword","skipOnEmpty"=>false,"on"=>["dologin"]],

            //再次确认密码
            ["password_compare","required","on"=>"register"],

            //再次确认密码和密码对比
            ["password_compare", "compare", "compareAttribute" => "password","message" => "两次密码不一致","on"=>"register"],

            /**验证码验证，在登录场景中，captchaAction的要设置正确，在user控制器中的公共actions中定义
            	public function actions()
		{
			return [
			  "captcha" => [
			      "class" => "yiicaptchaCaptchaAction",
			      "maxLength" => 5,
		              "minLength" => 5,
			      "height"=>30,
			      "backColor"=>0xFE2341,
			     "offset"=>2
			   ],
	                ];
		}
            */
            ["verifyCode","captcha","captchaAction"=>"user/captcha","on"=>["login"]]

        ];
    }

    public function scenarios()
    {
        $scenarios = parent::scenarios();
    	
    	//各个场景的活动属性
        $scenarios["register"] = ["useraccount", "username", "password","password_compare"];
        $scenarios["save"] = ["useraccount", "username", "password"];
        $scenarios["login"] = ["useraccount","password","verifyCode"];
        $scenarios["dologin"] = ["useraccount","password"];

        return $scenarios;
    
    }

    //这里是一些其他的登录认证函数..........
    

}

controller控制器UserController.php:

public function actions()
		{
		    return [
		         "captcha" => [
		              "class" => "yiicaptchaCaptchaAction",
		              "maxLength" => 5,
		              "minLength" => 5,
		              "height"=>30,
		              "backColor"=>0xFE2341,
		              "offset"=>2
		         ],
		     ];
		}


	public function actionRegister() {

			$model = new User();
			$model->setScenario("register");

			$id = Yii::$app->user->id;
			// var_dump($id);

			return $this->render("register",["model" => $model]);
		}

	public function actionSave() {

		$model = new User();

		$model->setScenario("save");

		$model->load($_POST);

  		if (Yii::$app->request->isAjax) {

   			Yii::$app->response->format = yiiwebResponse::FORMAT_JSON;

   			return yiiootstrapActiveForm::validate($model); 
  		}

		$account = Yii::$app->request->post("User")["useraccount"];

		$model->load(Yii::$app->request->post());

		$model->authkey = md5($account);

		$model->accesstoken = md5($account);

		$model->password = md5(Yii::$app->request->post("User")["password"]);

		$result = $model->save();
		
		if($result) {
			return $this->redirect(["index"]);
		}
	}

view的视图register.php：

<?php
use yiihelpersHtml;
use yiiwidgetsActiveForm;
?>
<style type="text/css">
    div.required label:before {
    content: " *";
    color: red;
}
</style>

<div class="register row" >
    <div class="col-lg-3">
    	<?php $form = ActiveForm::begin(["action" => ["user/save"],"enableAjaxValidation"=>true,"method"=>"post","options" =>["data-name"=>"yii","class"=>"form-horizontal"]]); ?>
        
        <?= $form->field($model, "useraccount",[
            "template"=>"<span class="glyphicon glyphicon-user"></span>{label}
{input}
{error}"

        ])->textInput(["placeholder" =>"请输入用户账号"])->label("用户账号") ?>

        <?= $form->field($model, "username")->textInput()->label("用户名称") ?>

        <?= $form->field($model, "password")->passwordInput()->label("密码") ?>

        <?= $form->field($model, "password_compare")->passwordInput()->label("确认密码") ?>
        
        <?= Html::submitButton("注册", ["class"=>"btn btn-mod btn-primary","name" =>"submit-button"]) ?>
        
        <?php  ActiveForm::end(); ?>
    </div>
</div>
