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"); } } } ?>
control层的代码如下：
//信息添加 添加显示页面和添加处理使用同一个方法 public function actionAdd(){ $user=new User(); if(isset($_POST['User'])){ // foreach ($_POST['User'] as $k =>$v){ // $user->$k=$v; // } if(is_array($_POST['User']['hobby'])) $_POST['User']['hobby']= implode(",", $_POST['User']['hobby']); //print_r($_POST['User']); $user->attributes=$_POST['User']; if($user->save()){ echo 'success'; }else{ echo 'error'; } } $this->renderPartial("new",array("model"=>$user)); }
其中，表单的自动验证，在model层实现，表单元素的名称与数据库中的字段名字一致，可设置错误信息进行提示。
