* @version Release: 3.2.13
* Uploaded file data, from $_FILES
* @param string Input field name attribute
* @param string Input field label
* @param mixed (optional)Either a typical HTML attribute string
* or an associative array
* Sets size of file element
* @param int Size of file element
$this->updateAttributes (array ('size' => $size));
* Returns size of file element
return $this->getAttribute ('size');
* Freeze the element so that only its value is returned
* Sets value for file element.
* Actually this does nothing. The function is defined here to override
* HTML_Quickform_input's behaviour of setting the 'value' attribute. As
* no sane user-agent uses <input type="file">'s value for anything
* (because of security implications) we implement file's value as a
* read-only property with a special meaning.
* @param mixed Value for file element
* Returns information about the uploaded file
