Yii2.0使用教程（五）

1、添加验证规则

打开/frontend/models/SignupForm.php

主要是修改增加验证码功能、用户名长度，以及修改密码时的第二次密码输入的操作，完成代码如下：

<?phpnamespace frontend\models;use yii\base\Model;use common\models\User;/** * 注册表单验证 */class SignupForm extends Model{    public $username;   //用户密码    public $email;      //邮箱    public $password;   //密码字段    public $repassword; //重复密码字段    public $verifyCode; //添加验证码字段    public function rules(){        return [            //用户名            ['username', 'filter', 'filter'涛救 => 'trim'],//截取前后空格            ['username', 'required'],            ['username', 'unique', 'targetClass' => '\common\models\User', 'message' => '该用户名已被使用！'],            ['username', 'string', 'min' => 6, 'max' => 16],//用户名字符限制,6-16位            ['username', 'match','pattern'=>'/^[(\x{4E00}-\x{9FA5})a-zA-Z]+[(\x{4E00}-\x{9FA5})a-zA-Z_\d]*$/u','message'=>'用户名由字母，汉字，数字，下划线组成，且不能以数字和下划线开头。'],                        //用户邮箱            ['email', 'filter', 'filter' => 'trim'],            ['email', 'required'],            ['email', 'email'],            ['email', 'string', 'max' => 255],            ['email', 'unique', 'targetClass' => '\common\models\User', 'message' => '该邮箱已经被注册！'],              腊率栗          //密码            [['password','repassword'], 'required'],            [['password','repassword'], 'string', 'min' => 6],                         //重复密码验证            ['repassword', 'compare', 'compareAttribute' => 'password','message'=>'两次输入的密码不一致！'],                        //验证码            ['verifyCode', 'captcha'],        ];    }    /**     * Signs user up.     *     * @return User|null the saved model or null if saving fails     */    public function signup()    {        if (!$this->validate()) {            return null;        }           珠睡     $user = new User();        $user->username = $this->username;        $user->email = $this->email;        $user->setPassword($this->password);        $user->generateAuthKey();                return $user->save() ? $user : null;    }    }

2、更改模板文件 /frontend/views/site/signup.php

本完整内容如下：

<?php/* @var $this yii\web\View *//* @var $form yii\bootstrap\ActiveForm *//* @var $model \frontend\models\SignupForm */use yii\helpers\Html;use yii\bootstrap\ActiveForm;use yii\captcha\Captcha;$this->title = 'Signup';$this->params['breadcrumbs'][] = $this->title;?><div class="site-signup">    <h1><?= Html::encode($this->title) ?></h1>    Please fill out the following fields to signup:    <div class="row">        <div class="col-lg-5">            <?php $form = ActiveForm::begin(['id' => 'form-signup']); ?>                <?= $form->field($model, 'username')->textInput(['autofocus' => true]) ?>                <?= $form->field($model, 'email') ?>                <?= $form->field($model, 'password')->passwordInput() ?>                                <?= $form->field($model, 'repassword')->passwordInput() ?>                                <?= $form->field($model, 'verifyCode')->widget(Captcha::className(), [                    'template' => '<div class="row"><div class="col-lg-3">{image}</div><div class="col-lg-6">{input}</div></div>',                ]) ?>                <div class="form-group">                    <?= Html::submitButton('Signup', ['class' => 'btn btn-primary', 'name' => 'signup-button']) ?>                </div>            <?php ActiveForm::end(); ?>        </div>    </div></div>

3、显示结果如下：
