You can upload data and files with one form using ajax.

PHP + HTML

<?
    print_r($_POST);
    print_r($_FILES);
?>

<form id="data" method="post" enctype="multipart/form-data">
    <input type="text" name="first" value="Bob" />
    <input type="text" name="middle" value="James" />
    <input type="text" name="last" value="Smith" />
    <input name="image" type="file" />
    <button>Submit</button>
</form>
jQuery + Ajax

$("form#data").submit(function(){

    var formData = new FormData($(this)[0]);

    $.ajax({
        url: window.location.pathname,
        type: 'POST',
        data: formData,
        async: false,
        success: function (data) {
            alert(data)
        },
        cache: false,
        contentType: false,
        processData: false
    });

    return false;
});

$("form#data").submit(function() {

    var formData = new FormData($(this)[0]);

    $.post($(this).attr("action"), formData, function(data) {
        alert(data);
    });

    return false;
});
