## 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.
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.
Finally, create the action view and generate a file upload field[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.
```php
$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.
