I am trying to build a progress bar for multiple files drag and drop upload by combining code from tutorial on multiple files drag and drop uploading [LINK] and tutorial on progress bar uploading [this video] . Javascript part is: var dropzone = document.getElementById("dropzone"); function updateProgress(e){ document.getElementById("progress").innerHTML = e.loaded + " of " + e.total; } function upload(files){ var formData = new FormData(), xhr = new XMLHttpRequest(), x; for(x = 0; x < files.length; x++){ formData.append("file[]", files[x]); } xhr.addEventListener("progress", updateProgress, false); xhr.open("post", "upload.php"); xhr.send(formData); } dropzone.ondrop = function(e){ e.preventDefa

I have created a nifty class for sanitizing inputs based on their source using PHP filter functions [LINK] , but there is no INPUT_FILES for filter_input_array() . Obviously, the routine for checking out a file is very involved and that is not the focus of this question (so, you can skip the php.ini, examine the file, copy the file, don't use the user supplied file name, tricks of the trade stuff, references to the manual, etc). I simply want to know, what is the source of the value for the size element in the $_FILES superglobal array.

I've been using a classic form upload with no JavaScript for the past few weeks, but decided that I wanted to have a progress bar and get a bit control of the upload from the uploading page (index.php) with some help of JavaScript. So I followed this video [this video] and ended up with this code for HTML: <form id="upload_form" method="post" enctype="multipart/form-data"> <div class="choose_file"> <span id="status" style="cursor: pointer;">Upload Audio File...</span> <input style="cursor: pointer;" type="file" name="fileToUpload" id="fileToUpload" accept=".mp3,.wav,.ogg" onchange="uploadFile()"> </div> </form> <progress id="progressBar" value="0" max="100" style="width:100%;"></progress> And thi
