Yii file upload $_FILE is empty


I am trying to upload a image by a form to my Model. I am using Yii 1.1

The model doesn’t contain in database the column “image”, so I have created the attribute in the model like this

public $image;

I have added in rules the following

array(‘image’, ‘file’, ‘types’=>‘jpg,gif,png’, ‘allowEmpty’=>true),

In the view I added to the form the htmlOption array(‘enctype’ => ‘multipart/form-data’), while for the file upload I did this:

<th><?php echo $form->labelEx($model, ‘image’); ?></th>

<td><?php echo $form->fileField($model, ‘image’);?></td>

<th><?php echo $form->error($model, ‘image’);’>’?></th>

I see the button for uploading the picture, when I press the button the action of my controller is called. I am showing in my controller a log with the $_POST and $_FILES, I receive all data related with my model, but I dont receive any data in $_FILES.

Log from the $_FILES

2016/07/07 18:18:12 [info] [application] FILE :




Log that I receive from the $_POST

[MyModel] => Array


    [Name] =&gt; My Name

    [Description] =&gt; What ever


    [image] =&gt; 


I have used Postman to call directly to the controller passing same data and image and in the log I can see in $_FILES the picture.

Any help?

The problem was related with the SubmitButtonAjax that was serializing the fields and the file field was converted to a string.
