1. The Model
2. The Controller
3. The View

The Model ¶

First declare an attribute to store the file name in the model class (either a form model or an active record model). Also declare a file validation rule for this attribute to ensure a file is uploaded with specific extension name.

class Item extends CActiveRecord
{
	public $image;
	// ... other attributes

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

You can add others validation parameters as described in [CFileValidator]. For instance, one can add a "maxSize" restriction (the PHP ini settings will of course prevail).

The Controller ¶

Then, in the controller class define an action method to render the form and collect user-submitted data.

class ItemController extends CController
{
	public function actionCreate()
	{
		$model=new Item;
		if(isset($_POST['Item']))
		{
			$model->attributes=$_POST['Item'];
			$model->image=CUploadedFile::getInstance($model,'image');
			if($model->save())
			{
				$model->image->saveAs('path/to/localFile');
				// redirect to success page
			}
		}
		$this->render('create', array('model'=>$model));
	}
}

[CUploadedFile::saveAs()] in one of the methods of [CUploadedFile]. You can also access directly to the file through its "tempName" property.

The View ¶

Finally, create the action view and generate a file upload field.

$form = $this->beginWidget(
	'CActiveForm',
	array(
		'id' => 'upload-form',
		'enableAjaxValidation' => false,
		'htmlOptions' => array('enctype' => 'multipart/form-data'),
	)
);
// ...
echo $form->labelEx($model, 'image');
echo $form->fileField($model, 'image');
echo $form->error($model, 'image');
// ...
$this->endWidget();

Another syntax is to use static calls in [CHtml] instead of [CActiveForm]. The result is the same as above.

<?php echo CHtml::form('','post',array('enctype'=>'multipart/form-data')); ?>
...
<?php echo CHtml::activeFileField($model, 'image'); ?>
...
<?php echo CHtml::endForm(); ?>
