The string [object File] gets uploaded in lieu of file content.

Safari version is 5.1 (7534.45) which comes with the latest preview of Mac OS X Lion. Tested on Chrome, etc. it works fine.

Config follows:

var uploader = new plupload.Uploader({
  runtimes:            "html5,flash,silverlight,gears,browserplus,html4",
  browse_button:       'browser',
  container:           'container',
  drop_element:        'dropper',
  max_file_size:       '50mb',
  url:                 resources,
  flash_swf_url:       "/javascripts/lib/plupload.flash.swf",
  silverlight_xap_url: "/javascripts/lib/plupload.silverlight.xap",
  multipart:           true,
  multipart_params: {
    authenticity_token: $('meta[name=csrf-token]').attr('content')
  }
});

(also posted in forum on plupload.com) After trying, buying and working days to implement Plupload 2 properly I am very unpleasantly surprised by the poor quality of resized images. It is not obvious on all photos, so I missed it at first. But on a lot of images you cannot ignore it. My goal is to use it for photography sites, so this is really not working good enough. (And before you suggest resizing on server; that way full size images have to be uploaded, this takes far too much time.)

It appears to happen in all runtimes (Flash, Silverlight and HTML5). Example: http://www.anothersite.nl/plupload.jpg - left=original, right=resized

I don't know how the client side resizing is done, but I do know that the wrong resample method is used! The used method preserves the hard edges. Programs like Photoshop or Irfanview offer different good methods for resampling.

So, my question: is it possible to use another, better method for (client side) resampling?

I know, that on http://www.plupload.com/index.php page it's explicitly said, that IE 10 isn't supported.

Is there any way to get dropzone upload support working in IE 10?

I'm using plupload 1.5.1.1 with enabled resize and Flash runtime as primary. When i try to upload multiple files - uploader freeze on random file in queue without any error, warnings on client and server. In log the next file doesn't start uploading (may be freeze on resize level)... Without resize enabled all files uploaded fine. It seems problem occured with flash player 11 installed, with flash player 10 uploads and resize fine. My tests results: IE8 + flash player 10 - fine IE8 + flash player 11 - freeze Firefox + flash player 11 - freeze Firefox + html5 - very fast and fine!

The current stable Safari for Windows has a bug that causes the upload of multiple files through the HTML5 runtime to fail. Curiously upload through HTML5 still works if only a single file is selected.

The problem seems to be related to the FileList object available through the input element. When more than one file is selected the file sizes are set to 0, the modification time is also set to 0. The resulting upload through the FormData object will upload a zero length (i.e. empty) file.

This bug does not seem to be a web-kit bug as the latest Chrome does not have the same problem.

I've logged an issue with Apple against Safari.

I've also created a basic test case that uses the same technique to upload files that plupload does using HTML5 on Safari. The test case is available here:

https://gist.github.com/1169709

(By the way I have not coded the test case to work around this webkit form bug which you may run into the second time you select files using the test)

Video uploads were working on iOS 6 but do not work on iOS 7. I can upload photos of any type or size from either os.

When trying to upload a video in iOS 7 it will show up in the file list but will not report a size. If I remove plupload from the equation and upload the video using a simple file form it appears to work.

I have a website where user's can upload their images. I am struck at IE10 not bringing file upload folder. I am using Plupload jQuery files with latest version(v1.5.6). It works very well with Firefox, Opera, Chrome and IE9 but not IE10.

Clicking on 'Upload' button does nothing but i can see new Div and input control created as

<div id="p17nd09rko1s8c1vaf1a401nkm1ph00_html5_container" class="plupload html5" style="position: absolute; background: none repeat scroll 0% 0% transparent; width: 0px; height: 0px; overflow: hidden; z-index: -1; opacity: 0; top: 0px; left: 0px;">
<input id="p17nd09rko1s8c1vaf1a401nkm1ph00_html5" type="file" multiple="multiple" accept="image/jpeg,image/gif,image/png" style="font-size: 999px; float:right">
</div>

I think it is unable to hook with 'browse_button' value in var uploader = new plupload.Uploader({.. })

Another thing I see is CSS generated is different in IE as compared to Mozilla.

My javascript

var uploader = new plupload.Uploader({
            runtimes : 'gears,html5,flash,silverlight,browserplus',
            browse_button : 'pickfiles',
            container : 'container',
            chunk_size: '1mb',
            unique_names: true,
            max_file_size : '5mb',
            max_file_count : 1,
            multi_selection: true,
            url: '<!-- my url -->',
            filters: [{ title: "Image files", extensions: 'jpg'}],
            flash_swf_url: '@Url.Content( "~/Scripts/plup/plupload.flash.swf" )',
            silverlight_xap_url: '@Url.Content("~/Scripts/plup/plupload.silverlight.xap")'
        });

Hope someone please help me with this?

Hi,

googling about Amazon and Plupload I read about this concern: " How do you ensure that the user’s browser communicates only with Amazon S3 and not an impersonator."

And the solution was simply using the HTTPS protocol, but this does not work with Plupload.

I would like to know if this is important to take care off, or not and that's why is not supported.

Thanks, loving Plupload more each day :)

Hi, I'm trying to use plupload (v1.2.1) in a CommonJS / Browserify environment

var plupload = require('libs/plupload/js/plupload.full.min');

But when that require runs I always get mOxie is undefined:

plupload.full.min.js:28 Uncaught ReferenceError: mOxie is not defined

Does plupload strictly depend on the mOxie module?

Im not sure this is related to being run in a CommonJS environment. I've looked into the source of plupload.dev.js and moxie.js and they don't seem to use the UMD pattern. Are they compatible with CommonJS?

Uploading directly to S3, there is an issue with Chrome's Flash. Amazon returns a '201 Created' response to Chrome, but somehow the flash front-end thinks it's an error and throws an error #2038.

Files are uploaded fine to S3. This does not occur in other browsers/platforms.

Chrome 21 implemented the possibility for folder drag & drop.

This patch adds a "relativePath" property to each instance of plupload.File.

Example: http://protonet.github.com/plupload/examples/drag_and_drop.html More details to the chrome implementation: http://wiki.whatwg.org/wiki/DragAndDropEntries Chromium issue: http://code.google.com/p/chromium/issues/detail?id=99823

Also this patch makes sure that the default behavior within dragover is only prevented when the drag contains any files otherwise there will be problems when eg. the drop_element is a <textarea> and the user is dragging text around.

Hi,

Please find attached a PDF file. This file will not upload to Wordpress. The process fails with a 403 error. We have spent many hours trying to work out where the issue lies and it seems to be with the PDF file itself. We have many other PDF files with the same fonts and styles and those seem to upload without issue.

The file seems to upload ok but fails when the file is attempting to be reconstructed and/or saved. Please also find attached an image of the console that shows the failed request and the stack trace.

The PDF file has all fonts embedded and displays correctly on a range of computers and mobile devices.

Uploading the PDF file via PDF into the uploads folder then adding the file to the server via a plugin works fine.

I reverted the libraries to the non-min versions so you can see which lines the process is ultimately failing on.

We have tried uploading this file in different versions of Wordpress (5.8 and 6.0.2) from different computers and in different web hosting environments. We have also tried disabling all plugins and even creating a completely vanilla install of Wordpress.

The file is consistently rejected.

There was one exception, on my Dev computer the upload works, however I do have the Adobe suite installed on it.

We are hoping you can provide some concrete advice that to what exactly is the issue with this file.

Park Lake Brochure Final V2.pdf

Let me know if you require any further information.

Cheers

Not sure if anyone has already done this or is interested, but I added some code in my version that generates a PDF preview if the document being uploaded is a PDF document. I'd have to go back and look what I actually did, but the result is like this:

Looks like it is in the FilesAdded event handler and requires adding:

FilesAdded: function(up, files) {
    // Called when files are added to queue
    log('[FilesAdded]');

    plupload.each(files, function(file) {
        //log('  File:', file.id);
        if(file.type == "application/pdf"){
        var fileReader = new FileReader();
        fileReader.onload = function() {

            var pdfData = new Uint8Array(this.result);
            // Using DocumentInitParameters object to load binary data.
            var loadingTask = pdfjsLib.getDocument({data: pdfData});
            loadingTask.promise.then(function(pdf) {
                console.log('PDF loaded');

                // Fetch the first page
                var pageNumber = 1;
                pdf.getPage(pageNumber).then(function(page) {
                // console.log(page._pageInfo.view);
                scale = 120 / (Math.max(page._pageInfo.view[2], page._pageInfo.view[3])) ;
                console.log('Page loaded');
                var viewport = page.getViewport({scale: scale});
                // Prepare canvas using PDF page dimensions
                let thumbcontainer = $('[id=' + file.id + ']').find(".plupload_file_dummy");
                var canvas = loadCanvas(thumbcontainer[0]);
                var context = canvas.getContext('2d');
                // Render PDF page into canvas context
                var renderContext = {
                canvasContext: context,
                viewport: viewport
                };
                var renderTask = page.render(renderContext);
                renderTask.promise.then(function () {
                console.log('Page rendered');
                });
            });
            }, function (reason) {
            // PDF loading error
            console.error(reason);
            });
        };
        fileReader.readAsArrayBuffer(file.getSource().getSource());
        }
    });

},

Hey,

I'm Hadas from the Snyk security team, I've been trying to contact your team via email from a while now. Is there any way to contact privately?

Thanks!

I get a DOMException 12 "Syntax err" when calling start() to upload selected files. This happens for some reason after I updated my Vue.js from 2.6.13 to 2.6.14 - when I downgrade it works again.

I googled this error and found other people with the same problem, unfortunately none of their solutions (correct ids, using setTimeout() to start upload) worked.
