本文實例講述了yii用戶注冊表單驗證實現方法。分享給大家供大家參考，具體如下：
視圖層：register.php
<?php
//使用小物件生成form元素
$form=$this->beginWidget('CActiveForm');
?>
<!--用戶名-->
<?php echo $form->labelEx($model,'username');?>
<?php echo $form->textField($model,'username');?>
<?php echo $form->error($model,'username');?>
<br>
<!--密碼-->
<?php echo $form->labelEx($model,'password');?>
<?php echo $form->passwordField($model,'password');?>
<?php echo $form->error($model,'password');?>
<br>
<!--確認密碼-->
<?php echo $form->labelEx($model,'password2');?>
<?php echo $form->passwordField($model,'password2');?>
<?php echo $form->error($model,'password2');?>
<br>
<!--郵箱-->
<?php echo $form->labelEx($model,'email');?>
<?php echo $form->textField($model,'email');?>
<?php echo $form->error($model,'email');?>
<br>
<!--性別-->
<?php echo $form->labelEx($model,'sex');?>
<?php echo $form->radioButtonList($model,'sex',array(1=>'男',2=>'女'),array("separator"=>" "));?>
<br>
<!--年級-->
<?php echo $form->labelEx($model,'grade');?>
<?php echo $form->dropDownList($model,'grade',array(0=>"--請選擇--",1=>"2010級",2=>"2011級",3=>"2012級"));?>
<?php echo $form->error($model,'grade');?>
<br>
<?php echo $form->labelEx($model,'hobby');?>
<?php echo $form->checkBoxList($model,'hobby',array(1=>"籃球",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層的代碼如下：User.php
<?php
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
class User extends CActiveRecord{
//創建一個模型的對象 靜態
public $password2;//非數據庫的字段，但是在view中需要用到
public static function model($className = __CLASS__) {
return parent::model($className);
}
//返回當前數據表的名字
public function tableName() {
//parent::tableName();
return '{{user}}';//這樣寫可以省略前綴
}
//設置標簽的顯示名字
public function attributeLabels() {
return array(
"username"=>"姓名",
"password"=>"密碼",
"password2"=>"確認密碼",
"email"=>"郵箱",
"sex"=>"性別",
"grade"=>"年級",
"hobby"=>"愛好",
);
}
//驗證表單域
public function rules() {
return array(
array("username","required","message"=>"用戶名不能為空"),
array("password","required","message"=>"密碼不能為空"),
//驗證密碼和確認密碼
array("password2","compare","compareAttribute"=>"password","message"=>"兩次密碼不一致"),
//驗證郵箱
array("email","email","allowEmpty"=>false,"message"=>"郵箱格式不正確"),
//驗證年級
array("grade","in","range"=>array(1,2,3),"message"=>"請選擇年級"),
//驗證愛好，使用自定義規則
array("hobby","checkHobby"),
);
}
//驗證愛好
function checkHobby(){
$this->hobby;
$len= strlen($this->hobby);
if($len<3){
$this->addError("hobby","愛好至少為2個以上");
}
}
}
?>
control層的代碼如下：
//信息添加 添加顯示頁面和添加處理使用同一個方法
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，表單的自動驗證，在model層實現，表單元素的名稱與數據庫中的字段名字一致，可設置錯誤信息進行提示。
希望本文所述對大家基於yii框架的PHP程序設計有所幫助。
