在更新用户信息的表单中，rules不起作用是怎么回事？ [ 新手入门 ]

发出代码来看看。。。

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('username, fullname, sex, classroom_id, grade_id', 'required'),
        array('password,confirmPassword', 'required','on'=>'create'),
        array('username','unique','on'=>'create,update'),//,'className'=>'User'
        array('password', 'compare', 'compareAttribute'=>'confirmPassword','on'=>'create,update'),
        //array('confirmPassword', 'compare', 'compareAttribute'=>'password','on'=>'update'),
        array('sex', 'numerical', 'integerOnly'=>true),
        array('username, password, fullname', 'length', 'max'=>16,'on'=>'create'),
        array('classroom_id, grade_id', 'length', 'max'=>8),
        array('photo','file','types'=>'jpg,gif,png','maxSize'=>'524288','allowEmpty'=>false,'on'=>'create'),
        array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements()),
        array('remark', 'safe'),
        array('fullname', 'match','pattern'=>"/^[\x7f-\xff]+$/",'message'=>"姓名只能是中文！"),//这行也能用。还有说是080
        array('username,password', 'match','pattern'=>"/^[".chr(0xa1)."-".chr(0xff)."A-Za-z0-9_]+$/",'message'=>"只允许字母、数字、下划线！"),
        // The following rule is used by search().
        // Please remove those attributes that should not be searched.
        array('id, username, password, fullname, sex, classroom_id, grade_id', 'safe', 'on'=>'search'),
        //array('password,confirmPassword','alter_pwd','on'=>'update'),
    );
}

这里面的哪个规则不管用呢？逻辑挺复杂的~

on 验证器将被应用到的情景模式的列表。数组的键-值都是情景模式的名称。
写成‘on’=>array('create','update')试试呢?

if($model->save()){
    Yii::app()->user->setFlash('updated','修改成功！');
    $this->refresh();//当用户刷新时去掉提示，而不是重复提交。
}

原来是$this->refresh搞的鬼，因为没有加大括号，导致一起刷新，唉.....辛苦各位了。
