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 app\models;
use Yii;
use yii\web\IdentityInterface;
use yii\db\ActiveRecord;
use yii\captcha\Captcha;

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 = \yii\web\Response::FORMAT_JSON;

return \yii\bootstrap\ActiveForm::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' => 'yii\captcha\CaptchaAction',
'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' => 'yii\captcha\CaptchaAction',
'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 = \yii\web\Response::FORMAT_JSON;

return \yii\bootstrap\ActiveForm::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 yii\helpers\Html;
use yii\widgets\ActiveForm;
?>
<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}\n{input}\n{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>
