我遇到了一个问题，我需要上传两个不同的文件（例如jpg类型和pdf / epub类型中的一个）以及其他表单数据。
表格数据应与文件路径一起上传到数据库，文件应保存在目录中。
任何帮助都将不胜感激。

究竟什么不起作用 - 将文件保存到文件系统中，o保存模型属性？您似乎没有在$model->save()中致电actionCreate。此外，如果模型属性被命名为file并且它用于处理上传文件，则在保存模型时这将是一个问题。您可能只想将文件名/文件路径保存到DB。在这种情况下，您需要其他属性来处理这些值。

您可以使用CMultiFileUpload小部件。见example in docs。不要忘记在表单中添加multipart/form-data：
$form = $this->beginWidget('CActiveForm', array(
'id'=>'user-form',
'htmlOptions' => array( 'enctype' => 'multipart/form-data' ),
));
文件可以与“附加表单数据一起”处理。另请参阅CUploadedFile。
