我在Yii中使用单选按钮,无论我做什么,我都无法获得所选按钮的值.我确信这只是一件简单的事情.我不使用radioButtonList,因为我希望每个按钮都存在于自己的div中,上面有一个图像.

这是我的视图中的代码……

<?PHP $this->pageTitle=Yii::app()->name; ?>

<h1>Welcome to <i><?PHP echo CHtml::encode(Yii::app()->name); ?></i></h1>

<div class="form">
<?PHP $form=$this->beginWidget('CActiveForm',array(
'id'=>'lead_form','enableAjaxValidation'=>false,)); ?>
<h3>Choose Your Prize!</h3>

 <div id="prizes">
<div class="prize">
<h3>Paypal</h3>
<?PHP echo $form->radioButton($model,'user_prize',array('value'=>1)); ?>
</div>
<div class="prize">
<h3>Check</h3>
<?PHP echo $form->radioButton($model,array('value'=>2)); ?>
</div>
<div class="prize">
<h3>AlertPay</h3>
<?PHP echo $form->radioButton($model,array('value'=>3)); ?>
</div>
<div class="prize">
<h3>Iphone 4</h3>
<?PHP echo $form->radioButton($model,array('value'=>4)); ?>
</div>
<div class="prize">
<h3>Ipad 2</h3>
<?PHP echo $form->radioButton($model,array('value'=>5)); ?>
</div>
<div class="prize">
<h3>Custom</h3>
<?PHP echo $form->radioButton($model,array('value'=>6)); ?>
</div>
</div>
<h3>Enter Your Email</h3>
<div id="mainemail">
<div class="row">
    <?PHP echo $form->labelEx($model,'user_email'); ?>
    <?PHP echo $form->textField($model,'user_emhttps://stackoverflow.com/editing-    helpail'); ?>
    <?PHP echo $form->error($model,'user_email'); ?>
</div>

<div>
    <?PHP echo $form->errorSummary($model); ?>
</div>

<div class="row buttons">
    <?PHP echo CHtml::submitButton('Submit'); ?>
</div>

endWidget(); ？>

<?PHP echo $form->radioButton($model,array('value'=>1,'uncheckValue'=>null)); ?>
<?PHP echo $form->radioButton($model,array('value'=>2,array('value'=>3,array('value'=>4,array('value'=>5,'uncheckValue'=>null)); ?>
