关于Yii 1.2框架

i have the question about how to call the Controller for View. I want to do upload my Picture to my host. i created the model upload with the name upload.php and put in model folder. like this "\protected\models"

<?php class Upload extends CActiveRecord {
public $image;
// ... other attributes

public function rules()
{
    return array(
        array('image', 'file', 'types'=>'jpg, gif, png', 'safe' => false),
    );
} }

then i made the Controller with the name UploadController.php and put in Controller folder. "\controllers\admin".

<?php class UploadController extends Controller
{
    public $layout='//content';
    
    public function actionCreate()
    {
        $model=new Upload;
        if(isset($_POST['Upload']))
        {
            $model->attributes=$_POST['Upload'];
            $model->image=CUploadedFile::getInstance($model,'image');
            if($model->save())
            {
                $model->image->saveAs('/../themes/default/images/shopimg');
                // redirect to success page
            }
        }
        $this->render('/admin/upload', array('model'=>$model));
    }
}

then made the view like this with name upload.php and put it in view folder

<div class="note">
    <div class="note_title">
        <a href="<?php echo Yii::app()->homeUrl; ?>admin">Admin area</a> &rarr; Add Picture
    </div>
    <div class="note_body">
        <?php if(Yii::app()->user->hasFlash('message')) echo Yii::app()->user->getFlash('message'); ?>
        <?php $form = $this->beginWidget(
        'CActiveForm',
    array(
        'id' => 'upload-form',
        'enableAjaxValidation' => false,
        'htmlOptions' => array('enctype' => 'multipart/form-data'),
    )
);
        ?>           
    <div class="form"><?php echo $form->errorSummary($model); ?></div>
        <table class="table_info">    
            <tr>
                <td><?php echo $form->labelEx($model, 'image');?></td>
                <td><?php echo $form->fileField($model, 'image');?></td>
                <td><?php echo $form->error($model, 'image');?></td>
                <td><?php echo CHtml::submitButton('Submit');?></td>
            </tr>
        </table>
    <?php $this->endWidget(); ?>
    </div>
</div>

then in my main page main.php i call that upload action with this code

                <td>
                    <a href="<?php echo Yii::app()->homeUrl; ?>admin/upload"><p>Items Upload</p>
                    Items Upload</a>
                </td>

but it not working i don't know what i missing ! i alway said "Error 404 Unable to resolve the request "upload". " what that mean ?

</div>

In yii url format will be based on controller and action.

Ex:- Controller name is UploadController and action is Create then url should be upload/create

<a href="<?php echo Yii::app()->homeUrl; ?>upload/create"><p>Items Upload</p>Items Upload</a>

if your controller is inside any module then url should be module_name/controller_name/action_name.
