如何在 Yii 1.6 中选中复选框列表

我是 Yii 框架的初学者，我用 Yii 小部件 CActiveForm 创建了_form.php。我已经序列化了操作创建的复选框值并保存到数据库表中。实际上的问题是，当我调用 actionupdate 时，我选中的值没有显示我已使用相同的表单_form.php在 actioncreate.actioncreate 和 actionupdate 上插入。

我在下面写了我的代码

1. 操作创建

   公共函数 actionCreate（）{ $model=新客户帐户;

   if(isset($_POST['CustomerAccounts']))
   {
       $model->attributes=$_POST['CustomerAccounts'];
       $model->DateCreated = date('Y-m-d H:i:s');
                   $model->DeliveryDay = serialize($_POST['CustomerAccounts']['DeliveryDay']);
       if($model->save()) {
                        Yii::app()->user->setFlash('success', 'Customer Account  create successfully.');
                        $this->redirect(array('admin'));
                   } else {
                       Yii::app()->user->setFlash('danger','An error occurred. Please try again.');
                   }
   }
   $this->render('create',array(
       'model'=>$model,
   ));
   

   }

2. 操作更新

   公共函数操作更新（$id）{ $model=$this->负载模型（$id）;

   if(isset($_POST['CustomerAccounts']))
   {
       $model->attributes=$_POST['CustomerAccounts'];
                   $model->DeliveryDay = serialize($_POST['CustomerAccounts']['DeliveryDay']);
       $model->DateCreated = date('Y-m-d H:i:s');
       if($model->save()) {
                        Yii::app()->user->setFlash('success', 'Customer  Account update successfully.');
                        $this->redirect(array('admin'));
                   } else {
                       Yii::app()->user->setFlash('danger','An error occurred. Please try again.');
                   }
   }
   $this->render('update',array(
       'model'=>$model,
   ));
   

   }

3. _form.php

<?php $form=$this->beginWidget('CActiveForm', array(
    'id'=>'customer-accounts-form',
    'enableAjaxValidation'=>false,
<div class="row">
        <div class="col-lg-12" style="padding-left: 34px;"> 
        <?php echo $form->labelEx($model, 'DeliveryDay'); ?>
        <?php echo $form->error($model, 'DeliveryDay'); ?> 
        <div id="checkbox" style="padding-left: 90px;">
            <?php
            $htmlOptions = array('template' => '<tr><td >{input}</td>&nbsp;&nbsp;<td> {label}</td>&nbsp;&nbsp;</tr', 'multiple' => true, 'checked' => 'checked');
            echo $form->checkBoxList($model, 'DeliveryDay', Yii::app()->params['WeekDays'], $htmlOptions);
            ?>
        </div></div></div>
<?php $this->endWidget(); ?>

这是我的模型

类客户帐户扩展了CActiveRecord{

public function tableName()
{
    return 'customer_accounts';
}
public function rules()
{
    return array(
        array('DeliveryDay, Status, CustomerID, Employee_ID, PaymentModeID', 'required'),
        array('CustomerID, Employee_ID, PaymentModeID, PcBottle, Bottle6Ltr, Bottle1500Ml, Bottle500Ml, TabStand, Pump, DispensirStatus, PCBottlesQuantity, PCBottleSecurity, DispensirQuantity, DispensirSerialNo, DispensirSecurity, TotalAmount, Status', 'numerical', 'integerOnly'=>true),
        array('DateJoin', 'length', 'max'=>250),
        array('Description', 'safe'),
        array('CustomerAccountID, CustomerID, Employee_ID, PaymentModeID, DateJoin, PcBottle, Bottle6Ltr, Bottle1500Ml, Bottle500Ml, TabStand, Pump, DispensirStatus, PCBottlesQuantity, PCBottleSecurity, DispensirQuantity, DispensirSerialNo, DispensirSecurity, TotalAmount, DeliveryDay, Description, Status, DateCreated', 'safe', 'on'=>'search'),
    );
}

public function relations()

    return array(
        'customer' => array(self::BELONGS_TO, 'Customer', 'CustomerID'),

        'paymentMode' => array(self::BELONGS_TO, 'PaymentMods', 'PaymentModeID'),
    );
}
public function attributeLabels()
{
    return array(
        'CustomerAccountID' => 'Customer Account',
        'CustomerID' => 'Customer',
        //'Employee_ID' => 'Employee',
        'Employee_ID' => 'Sale Person',

        'Description' => 'Description',
        'Status' => 'Status',
        'DateCreated' => 'Date Created',
    );
}
public function search()
{

    $criteria=new CDbCriteria;
    $criteria->compare('CustomerAccountID',$this->CustomerAccountID);
    $criteria->compare('CustomerID',$this->CustomerID);
    $criteria->compare('Employee_ID',$this->Employee_ID);
    $criteria->compare('PaymentModeID',$this->PaymentModeID);
    $criteria->compare('DateJoin',$this->DateJoin,true);
    $criteria->compare('PcBottle',$this->PcBottle);
    $criteria->compare('Bottle6Ltr',$this->Bottle6Ltr);
    $criteria->compare('Bottle1500Ml',$this->Bottle1500Ml);
    $criteria->compare('Bottle500Ml',$this->Bottle500Ml);
    $criteria->compare('TabStand',$this->TabStand);
    $criteria->compare('Pump',$this->Pump);
    $criteria->compare('DispensirStatus',$this->DispensirStatus);
    $criteria->compare('PCBottlesQuantity',$this->PCBottlesQuantity);
    $criteria->compare('PCBottleSecurity',$this->PCBottleSecurity);
    $criteria->compare('DispensirQuantity',$this->DispensirQuantity);
    $criteria->compare('DispensirSerialNo',$this->DispensirSerialNo);
    $criteria->compare('DispensirSecurity',$this->DispensirSecurity);
    $criteria->compare('TotalAmount',$this->TotalAmount);
    $criteria->compare('DeliveryDay',$this->DeliveryDay,true);
    $criteria->compare('Description',$this->Description,true);
    $criteria->compare('Status',$this->Status);
    $criteria->compare('DateCreated',$this->DateCreated,true);
    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
    ));
}

public static function model($className=__CLASS__)
{
    return parent::model($className);
}

}

当我调用操作更新时，任何人都可以告诉我如何从数据库表中显示选中的值？
