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. ### qq.FileUploader - Setting up full upload 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' }); ### Options of both classes ### // 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 // 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){}, messages: { // error messages, see qq.FileUploaderBasic for content }, showMessage: function(message){ alert(message); } Instance methods * setParams(newParams) #### Changing alert/messages to something more user friendly #### 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. #### Sending additional params #### 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. #### Troubleshooting #### 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 debug option 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. #### Contributors #### Thanks to everybody who contributed, either by sending bug reports or donating.
