yii用户注册表单验证实例

本文实例讲述了yii用户注册表单验证实现方法。分享给大家供大家参考，具体如下：

视图层：register.php

beginWidget('CActiveForm');
?>

labelEx($model,'username');?>
textField($model,'username');?>
error($model,'username');?>



labelEx($model,'password');?>
passwordField($model,'password');?>
error($model,'password');?>



labelEx($model,'password2');?>
passwordField($model,'password2');?>
error($model,'password2');?>



labelEx($model,'email');?>
textField($model,'email');?>
error($model,'email');?>



labelEx($model,'sex');?>
radioButtonList($model,'sex',array(1=>'男',2=>'女'),array("separator"=>" "));?>



labelEx($model,'grade');?>
dropDownList($model,'grade',array(0=>"--请选择--",1=>"2010级",2=>"2011级",3=>"2012级"));?>
error($model,'grade');?>


labelEx($model,'hobby');?>
checkBoxList($model,'hobby',array(1=>"篮球",2=>"足球",3=>"排球"),array("separator"=>" "));?>
error($model,'hobby');?>


endWidget();
?>

model层的代码如下：User.php

"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。

希望本文所述对大家基于yii框架的PHP程序设计有所帮助。
