Remy, Totally not intending to advertise for my company’s commercial offering (longtime reader of yours, just happened to see this due to a Question at Stack Overflow) and if I seem pushy or this comment is out of place I won’t be at all offended if you don’t approve it. But all of this reminds me why despite emerging technologies, we (Unlimi-Tech Software) continue to have success with our Java Applets including our uploaders. A script tag and it’s in your page ready for drag-and-drop, or you can use a headless scriptable version and your own bespoke drag-and-drop widget. The bummer is that Java SE applets aren’t supported for mobile devices (yet and probably never!). But the benefit is a crazy simple API and the ability to connect to an FTP server. If I had a site that relied on transfers as part of a commercial offering I would be tempted to go the opposite way in terms of fallbacks (vs. What was proposed in part of this article)– check for Java and use the applet, and if not then try to fall back to something based on HTML5 (which will likely be mobile).

In any event, all interesting stuff! Thanks for the step-by-step and for documenting the pitfalls you faced (all the better for learning!) Gets the brain turning on the different ways to accomplish file transfers from the web. @Greg While you may have better support for a java applet, I think it’s the wrong decision to use that as the default. We should always be throwing the web standards approach first and falling back to the proprietary technologies.

Why Need Drag And Drop File Upload. Actually, it is a question of creativity. Traditional file uploader also works great. But sometimes, you want to integrate something innovative file uploader like facebook, WordPress etc. Try this drag and drop HTML form creator. Simfatic Forms is a web form builder tool. Advanced File Uploader (with drag & drop, preview support) See Also. Build unlimited forms using this web form design software; Download and try this PHP MySQL web form builder.

This can also be done in Flash, which is probably even more supported but again, checking for support of the standard and falling back to flash is the way we should be heading. We see this pattern with many of the forward thinking video players such as – they will all check support for HTML5 video and fall back to flash if supported.

Gareth, There’s definitely something to what you say in principle! If you’re implementing a fallback one way or another, the question of coding ability becomes a moot point primary secondary you’re still writing the code. But the reason I suggested the order of fallback wasn’t due to preference for Java (I’m all for native when it makes sense) or the hurdle of coding ability, though; rather it was about availability of features. Without going into much detail (I did, and then just deleted it before hitting submit because it was wordy and boring!) the file transfer API for HTML5 doesn’t even scratch the surface of what might be needed by an organization that has file transfer as a critical part of their business. It might get there some day that would be nice!

But in the same way that our clients use HTTP transfers as a fallback, they will be more likely to use the new API as fallback also. I can see a day when some of our products switch to being native-first. The uploader that we’re talking about would probably be one of the first. Other applets like our two-way applet and our UDP-based transfer applets will probably not be able to have native versions within HTML5’s lifetime. Only time will tell! A brief note regarding availability: Java is far more present (95% ish) on the desktop than Flash (75% ish).

On mobile, neither are good choices. But that’s what the fallback would be for.;-). @zet – it really depends on what your application does, doesn’t it? What if the user is uploading txt files or pdfs? And those steps are definitely possible, when you render, copy it in to a canvas and add cropping tools.

Once done, use `drawImage` cropping the data in to a temp canvas and export to an image and send it quietly up to the server. Remember that disk space and cpu usage on the.server. is so much less important than the client. Because you’re machine can be beefy as heck, whilst you want your user to easily continue on with their job – not that any of these tasks described would consume anything short of a tiny amount of resource both on the client or server. Hi Remy, I’ve been using Drag n drop upload for a while in Firefox & Chrome, sometimes updating the code with the API changes. Now it seems drag ‘n drop upload is broken in Firefox 11 (I’m on Ubuntu 11.10). I’ve tracked the problem down in Firebug down to the e.dataTransfer.files property on the onDrop event.

For some reason, the “files” object always has a length of zero, no files, so it just skips out. Everything still works in Chrome. I’ve tried other examples on the web and even Gmail’s drop to attach file with my Firefox 11 and none of them seem to work. Just wondering if it’s a Firefox bug or something wrong with my install.

@Michael Butler DnD is working fine in FF11 on Windows. Unfortunately XHR2 doesn’t appear to be available yet. Admittedly I’m running my POST through jQuery’s ajax function, but an attempt to point xhr.upload.onprogress to a handler throws an error. I’m also a bit unhappy with the fact that FileReader doesn’t seem to make more than one or two calls to the progress event even for multi-megabyte files unless I’m throwing around hundreds of megs (which isn’t in my use-case) spending time on progress indicators seems to be a waste of time (even though a 2MB or 3MB file.is. in the use-case and takes enough time that progress updates would be useful). @Mac – I suspect your usage is off. I’m making a couple of assumptions, so firstly, using jQuery’s Ajax function doesn’t give you access to the XHR object.

It creates a bespoke jqXHR object: – this is a superset of XHR, but my gut tells me not everything is there. If you’re having an error thrown on adding a handler to onprogress I suspect it’s because the upload property is undefined – which supports my suspicion that you don’t actually have the real XHR object. Secondly, on the FileReader firing events often enough – again I suspect you’ve not hooked it properly (and I had the same problem the first few times around – the progress would appear to jump way too quickly). If you’re not able to hook the progress event on the upload property then it shouldn’t even update the progress indicator. Just for you own sanity and mine, I’ve captured a screencast showing progress on a 15mb file and an 800k file so you can see the speed in which the progress updates (this is on a regular 8mb+ broadband connection): Keep playing, it’s worth it once the hooks are properly in place. I tested this software, and it worked beautifully, BUT, as poster Kartoshin pointed out, you need square brackets in: formData.append(‘file’, filesi); rather than: formData.append(‘file’, filesi); THANK YOU, Remy, for all your fine work!:D ————- To the poster who was asking how to specify the location on the server, do the following: 1.

Start with the source code in Remy’s example, at 2. Replace xhr.open(‘POST’, ‘/devnull.php’); with: xhr.open(‘POST’, ‘where “YourScript.php” is a script on your server that you need to provide.

This script will receive the uploaded files — and it’s in this script that you provide the information about where in the server to store them. Your script should have a line of the type: $uploadedFiles = $FILES“file”; where the name “file” must be the string used in formData.append(‘file’, filesi).

(Careful not to mix up the singular with the plural – poor choice of similar variable names!) 4. All left to do in your script is the same as if you were doing a “regular” multiple file upload, i.e.

The kind you would do with. Essentially, looping over the arrays inside the variable $uploadedFiles, and moving the uploaded files from your server’s temporary folder to your desired destination – for example by means of the PHP function moveuploadedfile. @ Corey/Julian Thank you for your insight as to how to get file upload working to specify the location on the server. Im new to PHP and my problems have come when creating the script, ive played around with it for the past few days but cant seem to get it working? I was wondering whether the placing of: $uploadedFiles = $FILES“file”; within the script in relation to the above function could be the problem? Any help with this would be greatly appreciated as its driving me nuts at the moment:) Thanks in advance!

Im getting an error at line 2 $uploadedFiles = '; foreach ($FILES'file'error' as $key = $error) < if ($error UPLOADERROK) < $name = $FILES'file'name'$key; $uploadedFiles.=$name; moveuploadedfile( $FILES'file'tmpname'$key, 'uploads/'. $FILES'file'name'$key); its seems $FILES“file” is empty, but im adding the files to the formData for (var i = 0; i files array has one image in it. Wanted to pop in and thank you for a great start you gave me; I took it a different direction and thought that your readers might be interested: – The files list is inside the event, so if you don’t need to pass it into formData, you can post each individual file and get information from each file’s xhr2 object. This will allow you to do things like per-file progress updates. So, instead of pushing into the formData object, you can just use the event directly (in the case of a change event, it is event.target.files). – The “fallback” to the file input button is a great idea.

We decided to do something like this, but instead of “one or the other”, we always provide the input node. Only the drop area is optional and available on detection. To streamline everything, we therefore only trigger the upload from a “change” event on the input node. The drop widget takes the files object and throws it over to the input node (document.getElementById(‘files-upload’).files = event.originalEvent.dataTransfer.files;), which triggers the change event.

Hope that’s some sort of benefit to someone! Hi Remy, I am working on java – spring mvc. I am submitting my data through JSON. What I want to do is: I want to upload an image instantly in to temporary folder on my server using, and show what is to be uploaded. On final submit all data including uploaded image path (temporary folder’ path) will be passed to my spring controller through JSON object, then transfer image from temporary directory to actual directory & saved all data in to a database.

There are few questions: 1. Where the file is to be uploaded (location)?

Where to give folder path? I would be appreciated if you can hep me. Thanks in advance.
