How to upload file in Yii along with form data? - php

Question

I'm stuck at a problem where in I need to upload two different files (e.g. one of type jpg and the other of the type pdf/epub) along with the additional form data.
The form data should be uploaded to a database along with the path of the files and the files should be saved inside a directory.
Any help would be appreciated.

Answer 1

What exactly doesn't work – saving file into filesystem, o saving model attribute? It looks like you are not calling $model->save() in your actionCreate. Also if model attribute is named file and it is used to handle uploaded file here will be a problem when saving model. Probably you want to save only file name / file path to DB. In this case you need additional attributes to handle those values.

Answer 2

You can use CMultiFileUpload widget. See example in docs. And do not forget to add multipart/form-data to your form:
$form = $this->beginWidget('CActiveForm', array(
'id'=>'user-form',
'htmlOptions' => array( 'enctype' => 'multipart/form-data' ),
));
And file can be processed „along with the additional form data“. Also see CUploadedFile.
