yii使用者註冊表單驗證執行個體_php執行個體

本文執行個體講述了yii使用者註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//使用小物件產生form元素$form=$this->beginWidget('CActiveForm');?><?php echo $form->labelEx($model,'username');?><?php echo $form->textField($model,'username');?><?php echo $form->error($model,'username');?>
<?php echo $form->labelEx($model,'password');?><?php echo $form->passwordField($model,'password');?><?php echo $form->error($model,'password');?>
<?php echo $form->labelEx($model,'password2');?><?php echo $form->passwordField($model,'password2');?><?php echo $form->error($model,'password2');?>
<?php echo $form->labelEx($model,'email');?><?php echo $form->textField($model,'email');?><?php echo $form->error($model,'email');?>
<?php echo $form->labelEx($model,'sex');?><?php echo $form->radioButtonList($model,'sex',array(1=>'男',2=>'女'),array("separator"=>" "));?>
<?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');?>
<?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');?><?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{  //建立一個模型的對象 靜態  public $password2;//非資料庫的欄位，但是在view中需要用到  public static function model($className = __CLASS__) {    return parent::model($className);  }  //返回當前資料表的名字  public function tableName() {    //parent::tableName();    return '{{user}}';//這樣寫可以省略首碼  }  //設定標籤的顯示名字  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"=>"使用者名稱不可為空"),      array("password","required","message"=>"密碼不可為空"),      //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，使用自訂規則      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：

//資訊添加 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，表單元素的名稱與資料庫中的欄位名字一致，可設定錯誤資訊進行提示。

希望本文所述對大家基於yii架構的PHP程式設計有所協助。
