数据不在数据库（Yii框架）寄存器

Question

我有视图：

... 
<div class="row"> 
     <?php echo $form->labelEx($model,'content'); ?> 
       <?php $this->widget('application.extensions.ckeditor.CKEditor',array( 
         'model'=>$model, 
         'attribute'=>'content', 
         'language'=>'en', 
         'editorTemplate'=>'full',)); 
       ?> 
     <?php echo $form->error($model,'content'); ?> 
    </div> 

    <div class="row"> 
     <?php echo $form->labelEx($model,'status'); ?> 
     <?php echo $form->dropDownList($model,'status', array('0' => 'Not published', '1' => 'Published')); ?> 
     <?php echo $form->error($model,'status'); ?> 
    </div> 

     <div class="row"> 
     <?php 
      echo $form->labelEx($model,'category_id'); 
      echo CHtml::dropDownList('category_id','', Category::allCategory(), 
       array(
       'ajax' => array(
       'type'=>'POST', //request type 
       'url'=>CController::createUrl('subcategory/dynamicSubCategories'), //url to call. 
       //Style: CController::createUrl('currentController/methodToCall') 
       'update'=>'#subcategory_id', //selector to update 
       //'data'=>'js:javascript statement' 
       //leave out the data key to pass all form values through 
      ))); 
      echo $form->error($model,'category_id'); 
     ?> 
     </div> 

     <div class="row"> 
     <?php 
      echo $form->labelEx($model,'subcategory_id'); 
      echo CHtml::dropDownList('subcategory_id','', array()); 
      echo $form->error($model,'subcategory_id'); 
     ?> 
     </div> 

    <div class="row buttons"> 
     <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?> 
    </div> 

<?php $this->endWidget(); ?> 
... 

数据从字段“CATEGORY_ID”和“subcategory_id”不在数据库中写。所有其他字段成功注册。提示我如何将此字段与表单结合并解决此问题？

Answer 1

这是因为所保存的数据，应该是车型阵列中的数据的一部分，因此改变你的新要反映的字段名称MODELNAME[ATTRIBUTENAME]

echo CHtml::dropDownList('MODELNAME[category_id]', ... 

或者干脆更改为activeDropdownList

Answer 2

使用此方法dropDownLists

echo CHtml::activeDropDownList($model, 'category_id',Category::allCategory() 
.... 

或者更好的使用形式方法

echo $form->dropDownList($model, 'category_id', Category::allCategory() 
....
