I’m trying to use the **[Josegonzalez/Upload.Upload](https://github.com/FriendsOfCake/cakephp-upload)** plugin with CakePHP 3.x to manage file uploads.

My file field in the database is named **data\_file**. Accordingly, I’ve set the appropriate field configuration in the Model.

> ```
> $this->setTable( 'jobs' );
> $this->setPrimaryKey( 'id' );
> 
> $this->addBehavior( 'Timestamp' );
> $this->addBehavior( 'Utils.WhoDidIt',
> [
> 'fields' => ['id', 'username'],
> ] );
> 
> $this->addBehavior( 'Josegonzalez/Upload.Upload', [
> // You can configure as many upload fields as possible,
> // where the pattern is `field` => `config`
> //
> // Keep in mind that while this plugin does not have any limits in terms of
> // number of files uploaded per request, you should keep this down in order
> // to decrease the ability of your users to block other requests.
> 'data_file' => [
> 'fields' => [
> 'dir' => 'file_dir'
> ]
> ],
> 'nameCallback' => function ( $data, $settings ) {
> return strtolower( $data['name'] );
> },
> ] );
> 
> ```

In upload.ctp, I have the correct field name:

> ```
> <?= $this->Form->create( $job, [
> 'type' => 'file'
> ] ); ?>
> 
> <?= $this->Form->input( 'data_file', [
> 'label' => __( 'Upload CSV file' ),
> 'type' => 'file',
> 'class' => 'form-control'
> ] ); ?>
> 
> ```

Here’s the stack trace:

Thanks.

your `'nameCallback'` should be inside `'data_file'` block
