In short, for upload form with ajax, can be do with :

any form (in a jQuery-ui Dialog or not)
FormData ( a set of key/value pairs representing form fields and their values )

And the tips for jquery ajax call, is to define jquery with this two options (contentType, processData) set to false :

$.ajax({
            url: $url,
            type: 'POST',
            data: formData,
            processData: false, 
            contentType: false,
