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于yii框架的PHP程序設計有所幫助。
