After some research I found that you can do it with:

$.ajax({
    url: 'track.php',
    type: 'POST',
    data: new FormData($("#submit_pics")[0]),
    processData: false,
    contentType: false
}).

I'm Java programmer (Liferay) and in the server I use this to get the File:

UploadPortletRequest uploadRequest = PortalUtil.getUploadPortletRequest(request);
File File1 = uploadRequest.getFile("file1");
File File2 = uploadRequest.getFile("file2");

I supose something similar exists in php.

Unfortunately you can not upload files through XMLHttpRequest. AJAX doesn’t actually post forms to the server, it sends selected data to in the form of a POST or GET request. Javascript is not capable of grabbing the file from the users machine and sending it to the server

You can use a tricky workaround, posting (without AJAX) the request to an hidden iframe.

Have a look at this TUTORIAL

Is this true? This blog says otherwise: http://portfolio.planetjon.ca/2014/01/26/submit-file-input-via-ajax-jquery-easy-way/ – Rosdi Kasim Apr 11 '14 at 08:35

It used to be true, yes. Now most browsers are up to date and allow this. Although, I believe IE still has some protective feature to not post unless the user manually clicks the submit. – Anthony Mason Jul 12 '16 at 18:08

You should take a look at the JQuery Form Plugin. With that you can easily programmatically submit any form you have.

You can't do it via $.ajax() but you can use this uploadify plugin.

This code works for me

 _private.saveFile=function(){
      var formElement = $("#formId")[0];
      var _params = new FormData(formElement),
          _url = $(formElement).attr("action");

      _private.postFile(_url,_params,function(data,error){ 
           console.log(data);
           console.log(error);
      });
 }


_private.postFile=function(_urlService,_parameters,callback){
    var _url= _public.getPath()+_urlService;
    _private.httpPostFile(_url,callback,_parameters);
};

_private.httpPostFile=function(_url,callback,_data){

    $.ajax({
        url: _url,
        type: 'POST',
        data: _data,
        mimeType: "multipart/form-data",
        contentType: false,
        cache: false,
        processData: false,
        success: function (data, textStatus, jqXHR) {
            callback(data,null);
        },
        error: function(xhr, status, error) {
            console.log('error ',error);
            console.log('status ',status);
            console.log('xhr ',xhr);
            callback(null,error);
        }
    });
}
