yii用户注册表单验证实例

本文实例讲述了yii用户注册表单验证实现方法。分享给大家供大家参考，具体如下：

视图层：register.php

<?php//使用小物件生成form元素$form=$this->beginWidget('CActiveForm');?><!--用户名--><?php echo $form->labelEx($model,'username');?><?php echo $form->textField($model,'username');?><?php echo $form->error($model,'username');?><br><!--密码--><?php echo $form->labelEx($model,'password');?><?php echo $form->passwordField($model,'password');?><?php echo $form->error($model,'password');?><br><!--确认密码--><?php echo $form->labelEx($model,'password2');?><?php echo $form->passwordField($model,'password2');?><?php echo $form->error($model,'password2');?><br><!--邮箱--><?php echo $form->labelEx($model,'email');?><?php echo $form->textField($model,'email');?><?php echo $form->error($model,'email');?><br><!--性别--><?php echo $form->labelEx($model,'sex');?><?php echo $form->radioButtonList($model,'sex',array(1=>'男',2=>'女'),array("separator"=>" "));?><br><!--年级--><?php echo $form->labelEx($model,'grade');?><?php echo $form->dropDownList($model,'grade',array(0=>"--请选择--",1=>"2010级",2=>"2011级",3=>"2012级"));?><?php echo $form->error($model,'grade');?><br><?php echo $form->labelEx($model,'hobby');?><?php echo $form->checkBoxList($model,'hobby',array(1=>"篮球",2=>"足球",3=>"排球"),array("separator"=>" "));?><?php echo $form->error($model,'hobby');?><!--提交--><?php echo CHtml::submitButton('提交');?><?php$this->endWidget();?>

model层的代码如下：User.php

<?php/* * To change this template, choose Tools | Templates * and open the template in the editor. */class User extends CActiveRecord{  //创建一个模型的对象 静态  public $password2;//非数据库的字段，但是在view中需要用到  public static function model($className = __CLASS__) {    return parent::model($className);  }  //返回当前数据表的名字  public function tableName() {    //parent::tableName();    return '{{user}}';//这样写可以省略前缀  }  //设置标签的显示名字  public function attributeLabels() {    return array(      "username"=>"姓名",      "password"=>"密码",      "password2"=>"确认密码",      "email"=>"邮箱",      "sex"=>"性别",      "grade"=>"年级",      "hobby"=>"爱好",    );  }  //验证表单域  public function rules() {    return array(      array("username","required","message"=>"用户名不能为空"),      array("password","required","message"=>"密码不能为空"),      //验证密码和确认密码      array("password2","compare","compareAttribute"=>"password","message"=>"两次密码不一致"),      //验证邮箱      array("email","email","allowEmpty"=>false,"message"=>"邮箱格式不正确"),      //验证年级      array("grade","in","range"=>array(1,2,3),"message"=>"请选择年级"),      //验证爱好，使用自定义规则      array("hobby","checkHobby"),    );  }  //验证爱好  function checkHobby(){    $this->hobby;    $len= strlen($this->hobby);    if($len<3){      $this->addError("hobby","爱好至少为2个以上");    }  }}?>
