Javascript :: Flash Library For File Upload With File Size Limit And Progress Bar?
Jan 13, 2012
Is there any "mainstream" library used for this purpose? Commonly spread, well maintained, documented etc.I found these (using flash):
Uploadify - not many releases, latest 12/2010, no documentation (!)
SWFUpload - latest release 03/2010, documentation
fancyupload - looks buggy.
phpfileuploader - looks heavyweight, and looks commercial (?) I cannot read the licence (you can download it but are you allowed to use it forever without paying?) plupload New version of pure javascript (no flash) Valums' ajax upload claims to handle file size limit and progress bar, which is quite suspicious to me: these features require to guess the file size before the upload, which seems impossible in javascript (look also here). Or can it work?
I am building an Adobe AIR app and integrated an FTP client for file transfers. But I found out that maximum file upload size is 100 MB. I need to transfer bigger files
I have found this great tutorial, about uploading files with a Flex app, using Php to do the server scripting for us.
http:[url]....Its great, but i wanted to know what changes should i do at the ActionScript so that only accepts image files, and if possible to limit the file size upload and show a message when one of these conditions are violated.
I'm trying to track the progress of a file upload in AS3, and I'm getting strange behavior. When I select a file and upload it, the progress is instantaneously 100% even if the file is 10 or more megabytes, but it's not finished. The onComplete event is fired about 30 second to a few minutes later (depending on file size) when the file has really finished uploading. I've tested this locally and on the server, the behaviour is the same. Has anyone else experienced this? Very frustrating ...
Otherwise, the file is uploading fine. The code is simple:
myFileReference.addEventListener(ProgressEvent.PROGRESS, onUploadProgress); function onUploadProgress(e:ProgressEvent) { var pctDone:Number = (e.bytesLoaded / e.bytesTotal) * 100; trace(pctDone); }
I am trying to upload image files to my server using AS3 and PHP, and at the moment I am succeeding in uploading multiple files and restricting it to images only, but since I am finding it difficult to figure out how to have a loader bar show when the files are being uploaded, as well as executing a function once all files have been uploaded to go to a specified frame.
Is it possible to pass file names from a running Flash application, which only purpose is to enable multiple-file-selection, to a JavaScript application which handles upload of all files to the server?I have examined various Flash upload solutions (like SWFUpload, Uploadify, etc.) and none of them meets my needs. I want an easy to implement solution (like Uploadify) which also lets me specify various parts of the HTTP request.
The reason I need this is because my upload form uses session cookies (for user authentication) and an CSRF token both passed to the server when uploading files.Is it technically possible to pass filenames (+ paths) to a JavaScript application which then handles the upload?
I am trying to create a multiple file upload flash application to be called from an External Interface, but it isn't working.
AS3:
var fileRef:FileReferenceList; ExternalInterface.addCallback('selectFiles', showDialog); function showDialog()
[Code].....
When I run the script and comment out the fileRef parts and uncomment the alert call, it shows the alert, also when I comment out the ExternalInterface call, leaving only the fileRef parts, it shows the file upload dialog.
When I run it as intended, I get the following error:
I was just wondering that is there a way to create a multiple file select like Facebook (using flash, I think.) and with a progress bar that show every photos progress in one progress bar. Have a clue or a script which can be customized and can be used easily?
Is there a limit to the size of video file an instance of FLVPlayback can handle? I have a set of H.264 encoded .mov files, and all but one of them run fine. There is one file that starts buffering, but even when the browser has downloaded the whole video, it still doesn't play. The file is ~300MB.
I have been asked to compress a commercial for a client for web. The spot is 300x250 at 10 seconds and I am exporting an flv out of After Effects. I have taken the bit rate down as low as possible and can only get it down to about 872kb. Is there any solution to lowering it down to the required 40k file size.
Also, for delivery would i just need to send the swf and html or does the flv need to go
In a project we use large flash FLA file with lots of graphic assets, but the actual data that is changed is just in a few symbols. Sometimes it is not very efficient to transfer the whole FLA file that comes up to 20MB now.
I was thinking about using Shared Libraries, but it seems that, even if you import external library, it still copies the whole assets into the destination file, but does not link it from external file. Consequently, size of the FLA file still remains the same.
Is there any way to split FLA files into few separate in order to minimise size of the most frequently updated file and keep all unchanged data in another file?
what is the total maximum file size that the flash cs4 library can hold?? because im experiencing error, right now, i have too many objects in the library.is it because of the too many items in the library?
On a webpage, is it possible to split large files into chunks before the file is uploaded to the server? For example, split a 10MB file into 1MB chunks, and upload one chunk at a time while showing a progress bar?
It sounds like JavaScript doesn't have any file manipulation abilities, but what about Flash and Java applets?
This would need to work in IE6+, Firefox and Chrome. Update: forgot to mention that (a) we are using Grails and (b) this needs to run over https.
I'm looking for a multiple file upload button. the ones I've found areswfuploaduploadifyI want to integrate it in a django app. ATM the only one which is working without any problems and is in widespread use seems to be swfupload.
Does anyone know the file upload hack for Flex, which will allow files to be uploaded to authenticated web services via multipart form post? In this bug report from the Adobe site, a user reports: Flash isn't cross-browser compatible if this feature only works via Javascript hacks. So far, I've been unable to craft such a hack. I'm unsure what to do next. Here's what I've tried so far (all have been unsuccessful or impossible). Set cookies on url Pass cookies to Flex URLRequest Create hidden html form in javascript to post file
Basically I'll be working with large XML files (approx. 20 - 50 MB). These files needs to be uploaded on a server.I know it isn't possible to touch the files with javascript, nor to implement HTTP compression on the client-side.
My question is that if any solution exists (flash / action script) that compresses a file and has a javascript API? The scenario is this:
Trying to upload 50 MB XML file Before upload a grab it with Javascript and send it to the compressor.Upload the compressed file instead of the original one.
I'm looking for multiple file upload component with alternative ways.I need HTML5, Flash and normal upload support, depended by device.I don't like FancyUpload, because it uses mootools and mootools is very big library.Also I can't use jQuery, because I'm writing on Ext js and it's not good idea to use two big library like jQuery and Ext js.
I have an upload form for an image. The user clicks browse and selects a file. How can I get the image dimensions the moment the user selects the file (before the file is even uploaded to the server). It obviously has to be something client-side with maybe javascript/jquery or flash/flex (prefer js//jquery though), but can either of them do this? This is the code I'm using to tie into zozo's getImgSize() function, but it gives me 0*0 as size.
my listener.onComplete = function(selectedFile:FileReference) is fired without any file in the upload dir. if the file is small and I wait a bit I can see the file (through FTP) coming up on the server, but most of the times the "onComplete" if fired without any file being saved.
can I add something to this php code to make sure the file is uploaded?
If you have an .as file in the global include directory do you have to upload it to your server with the flash file or does it compile the flash file with the included info?
I tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.
is there a simple way to just pull back a true or false value from an associated javascript file to a flash file? here is what i have:
Code: var bincheck:Boolean = fscommand("eval", "parent.check_bins(\'"+img+"\')"); if (!bincheck){return false;} return true;
check_bins(img) is a function in my javascript file that simply iterates through an array, returning false if "img" is found. im simply trying to get the true or false value back into flash, but its not proving that simple. i added a couple alerts so that i could see what the "bincheck" value was, and i keep getting an 'undefined' value for "bincheck" in flash.
I have developed a video player in adobe flash cs4 and used all vector arts but when I open this fla file in Adobe Flash CS5 and published it, the swf file size more then fla file.
I would like to run a .swf file into an existing flash file, but the dimension size of the .swf file is too big. I am a beginner to flash and not sure of the steps to execute this. Would anyone be willing to walk me through the steps to import the code?
I have the need to change a variable in a child Flash file.
The setup is a parent Flash file, that has called a child Flash, and placed it in a movieClip.
I can send a variable using Javascript to the parent Flash file, but not directly to the child Flash file. Is there a way that I can access the child Flash file directly with Javascript?
Or do I need to send the variable to the parent Flash file, and then have the parent send the variable to the child Flash file? Is there a sort of dot notation that I can use with Javascript to get to the child Flash file without first accessing the parent, when the child is added to the parent using the loadClip function in flash?
