yii用户注册表单验证

注册表单的验证

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。
