Notice:
This project made some improvements to Valum's initial AJAX uploader, but it is no longer actively maintained. Some bugs may remain unfixed. A commercial fork of this project (with a licencing fee) with many bugfixes is available at http://fineuploader.com/.
Interested maintainers for this project may post on the issues forum.
Welcome! This project attempts to achieve a user-friendly file-uploading experience over the web. It's built as a Javascript plugin for developers looking to incorporate file-uploading into their website.
This is a public fork of Valum's File Uploader (v1) in an attempt to incorporate some of the best bugfixes and patches to make a version compatible with the latest browsers in 2012.
We would love developers to contribute any improvements and bugfixes they produce. See How do I contribute to other's code in GitHub?.
Initiated by SimonEast, but interested maintainers are welcome.
This plugin uses an XMLHttpRequest (AJAX) for uploading multiple files with a progress-bar in FF3.6+, Safari4+, Chrome and falls back to hidden-iframe-based upload in other browsers (namely IE), providing good user experience everywhere.
It does not use Flash, jQuery, or any external libraries.
- Multiple file select, progress-bar in FF, Chrome, Safari
- Drag-and-drop file select in FF, Chrome
- Uploads are cancellable
- No external dependencies
- Doesn't use Flash
- Fully working with HTTPS
- Keyboard support in FF, Chrome, Safari
- Tested in IE7/8, Firefox 3/3.6/4, Safari 4/5, Chrome, and Opera 10.60
This plugin is open sourced under GNU GPL 2 or later and GNU LGPL 2 or later.
Plugin breaks back button functionality in Opera.
The fileuploader.js contains two classes that are meant to be used directly.
If you need a complete upload widget (from demo) to quickly drop
into your current design, use qq.FileUploader.
If you want to customize uploader, by using a different looking file list
or change the behaviour or functionality use qq.FileUploaderBasic.
The difference between them is that qq.FileUploader provides a list of files,
drag-and-drop, but qq.FileUploaderBasic only creates button and handles validation.
Basic uploader is easier extendable, and doesn't limit possible customization.
qq.FileUploader extends qq.FileUploaderBasic, so that all the options present
in the basic uploader also exist in the full widget.
Include fileuploader.js and fileuploader.css into your page.
Create container element.
<div id="file-uploader">
<noscript>
<p>Please enable JavaScript to use file uploader.</p>
<!-- or put a simple form for upload here -->
</noscript>
</div>Initialize uploader when the DOM is ready. Change the action option. For example ../server/php.php for the default folder structure. In the server folder you will find examples for different platforms. If you can't find the one you need, check the readme.txt in the same folder.
var uploader = new qq.FileUploader({
// pass the dom node (ex. $(selector)[0] for jQuery users)
element: document.getElementById('file-uploader'),
// path to server-side upload script
action: '/server/upload'
}); // url of the server-side upload script, should be on the same domain
action: '/server/upload',
// additional data to send, name-value pairs
params: {},
// validation
// ex. ['jpg', 'jpeg', 'png', 'gif'] or []
allowedExtensions: [],
// each file size limit in bytes
// this option isn't supported in all browsers
sizeLimit: 0, // max size
minSizeLimit: 0, // min size
abortOnFailure: true, // Fail all files if one doesn't meet the criteria
// set to true to output server response to console
debug: false,
// events
// you can return false to abort submit
onSubmit: function(id, fileName){},
onProgress: function(id, fileName, loaded, total){},
onComplete: function(id, fileName, responseJSON){},
onCancel: function(id, fileName){},
onError: function(id, fileName, xhr){}
messages: {
// error messages, see qq.FileUploaderBasic for content
},
showMessage: function(message){ alert(message); } Instance methods
setParams(newParams)
If you limited file types and max size, you will probably want to change the default alert and messages as you see fit, this is possible using showMessage callback and messages option.
To add a parameter that will be passed as a query string with each upload use params option.
var uploader = new qq.FileUploader({
element: document.getElementById('file-uploader'),
action: '/server-side.upload',
// additional data to send, name-value pairs
params: {
param1: 'value1',
param2: 'value2'
}
});To change params based on the state of your app, use
uploader.setParams({
anotherParam: 'value'
});It can be nicely used in onSubmit callback.
If you can't get the uploader to work, please try the following steps before asking for help.
If the upload doesn't complete, saying "failed":
- Set the
debugoption of the FileUploader to true. - Open the page where you have a FileUploader.
- Open developer console in your browser.
- Try to upload the file. You should see a server serponse.
It should be {success:true} for completed requests. If it's not,
then you have a problem with your server-side script.
