Disabled fields not picked up by serializeArray

you can use readonly serializeArray() can read it.

Try this

var data = $('form').serializeAllArray();

And here is the small plugin that is used

(function ($) {
  $.fn.serializeAllArray = function () {
    var obj = {};

    $('input',this).each(function () { 
        obj[this.name] = $(this).val(); 
    });
    return $.param(obj);
  }
})(jQuery);

You can also try enabling all your element's just to serialize them and then disable them after serializing.

var myform = $('#form');
var disabled = myform.find(':input:disabled').removeAttr('disabled');
var serialized = myform.serializeArray();
disabled.attr('disabled','disabled');
