    <p>With jQuery (and without FormData API) you can use something like this: </p> <pre><code>function readFile(file){ var loader = new FileReader(); var def = $.Deferred(), promise = def.promise(); //--- provide classic deferred interface loader.onload = function (e) { def.resolve(e.target.result); }; loader.onprogress = loader.onloadstart = function (e) { def.notify(e); }; loader.onerror = loader.onabort = function (e) { def.reject(e); }; promise.abort = function () { return loader.abort.apply(loader, arguments); }; loader.readAsBinaryString(file); return promise; } function upload(url, data){ var def = $.Deferred(), promise = def.promise(); var mul = buildMultipart(data); var req = $.ajax({ url: url, data: mul.data, processData: false, type: "post", async: true, contentType: "multipart/form-data; boundary="+mul.bound, xhr: function() { var xhr = jQuery.ajaxSettings.xhr(); if (xhr.upload) { xhr.upload.addEventListener('progress', function(event) { var percent = 0; var position = event.loaded || event.position; /*event.position is deprecated*/ var total = event.total; if (event.lengthComputable) { percent = Math.ceil(position / total * 100); def.notify(percent); } }, false); } return xhr; } }); req.done(function(){ def.resolve.apply(def, arguments); }) .fail(function(){ def.reject.apply(def, arguments); }); promise.abort = function(){ return req.abort.apply(req, arguments); } return promise; } var buildMultipart = function(data){ var key, crunks = [], bound = false; while (!bound) { bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf()); for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; } } for (var key = 0, l = data.length; key &lt; l; key++){ if (typeof(data[key].value) !== "string") { crunks.push("--"+bound+"\r\n"+ "Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+ "Content-Type: application/octet-stream\r\n"+ "Content-Transfer-Encoding: binary\r\n\r\n"+ data[key].value[0]); }else{ crunks.push("--"+bound+"\r\n"+ "Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+ data[key].value); } } return { bound: bound, data: crunks.join("\r\n")+"\r\n--"+bound+"--" }; }; //---------- //---------- On submit form: var form = $("form"); var $file = form.find("#file"); readFile($file[0].files[0]).done(function(fileData){ var formData = form.find(":input:not('#file')").serializeArray(); formData.file = [fileData, $file[0].files[0].name]; upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); }); }); </code></pre> <p>With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})</p>

    1. COThis solution does not address the limitation that XMLHttpRequest.send() imposes upon the data funnelled through it. When passed a string (such as your multipart), send() does not support binary data. Your multipart here will be treated as a utf-8 string, and will choke on or corrupt binary data that is not valid utf-8. If you really need to avoid FormData, you need to use XMLHttpRequest.sendAsBinary() ([polyfill available](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#sendAsBinary()). Unfortunately this means that using jQuery for the ajax call becomes much more difficult.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
