I have put multipart/form-data in form ( although script seem dont must put )

Did you put

enctype="multipart/form-data"

in your form declaration?

The problem is because you are using Ajax file upload. Ajax file upload actually created a hidden tag where there is normal form with file upload element.

This is the root of the problem. iframe look like a separate page and Firebug cannot handle the post of this request. Also the fields probably are totally different than Cake's convention.

I had the same problem in the past and I struggled with the same thing. :) My advise - use normal upload.

Use: // Read binary input stream and append it to temp file $in = fopen("php://input", "rb");
