* SWFUpload v2.0 by Jacob Roberts, Nov 2007, www.swfupload.org, linebyline.blogspot.com * --------- Version 2.0.1 ----------- * = Fixed a bug where zero-byte files would stop file the queuing process. * = Finished updating Features Demo * + Added GetFileByIndex(i) that gets a JavaScript File Object. The index never changes. Finished files continue to be available. * The JavaScript GetFile function will accept a file_id or an index. * + Added CheckFileSize constants to replace the magic numbers * + Added some code in an attempt to fix "Script is running slowly" error messages * = Better cleanup of FileReference objects * --------- Version 2.0 ----------- * + Re-created SWFUpload in Actionscript v2 for Flash 8 compatibility. Flash 8 loses POST and Server Data features. The two versions are otherwise fully compatible. * Flash 8 uses URL to pass post_params/file_params. * = Changed uploadStart event so it's part of the setTimeout/eventQueue workaround. This allows Flash functions to be called from uploadStart. * = Renamed uploadComplete to uploadSuccess and fileComplete to uploadComplete. All started uploads call uploadComplete (even if cancelled or stopped). * = Changed startUpload validation failure behavior. Rather than cancelling the upload the file is now requeued. Devs can cancel * or do whatever the need to in uploadError to handle the problem. * = Fixed fileQueueLimit/fileUploadLimit logic so it works correctly. * = Moved the upload request building to a later point so that the post params and file params can be updated in uploadStart. * - Removed the last of the UI stuff (ui_container, degraded_container). * + Started development on Plug-ins. Graceful Degradation, v1.0.2, Cookies, Queue Handling * = Fixed missing file_status field in FileItem. * + Added modificationDate to FileItem (file object) * + Added setStats function that lets you change the file upload count, etc. This will give more power over the queue limits. Not well tested. * = Renamed compeleted_uploads to successful_uploads in getStats object * + Added in_progress to getStats object * --------- Revision 7.0 beta 3 ----------- * + Added an "event queue". Events are added to an array and executeEvent is called on a setTimeout. This prevents out of order issues that occur * in the Safari browser. * + Added a check for the UPLOAD_COMPLETE_DATA event constant which only became available in Flash Player 9.0.28. This * fixes the Flash Version detection (Flash Object Detection) which was accepting Flash Player 9 versions before 9.0.28. * - Removed old code block that was missed when moving from a Flash Timer to the JavaScript timeout (caused certain cancel events to be called twice) * = Change ShowUI to the swfUploadLoaded event which will hopefully make it more clear that this is an overrideable event * = Changed flashReady to behave like the other events (uses setTimeout and the Event Queue). * --------- Revision 7.0 beta 2 ----------- * = Changed ERROR_CODE_FILE_NOT_FOUND to ERROR_CODE_FILE_ID_NOT_FOUND * + Grouped the error code constants in objects for queue errors and upload errors. * + Added an UPLOAD_STOPPED error code. * = Changed Event calling method (using Timer) in Flash. Timer is no longer called * instead setTimeout is called in JavaScript. This includes a change to the * JavaSCript design so the Event methods are not directly overridden but stored * internally and called if defined (with a setTimeout). This is an effort * be more compatible with the current Flash Player on Linux * = Changed the parameter order for the fileQueueError and uploadError events so the fileObj is first, like other events. * + Added an empty JavaScript object (customSettings) where users can store settings associated with the instance. * + Worked around an escaping bug in the ExternalInterface library by escaping all backslashes in out-going strings. * = Updated all the demos. * --------- Revision 7.0 beta 1 ----------- * = Redesigned the Event Chain * - Removed much of the queue concepts * - Removed the fileValidation events. This can be done in the new uploadStart event * - Removed beginUploadOnQueue feature. This can be done in the new dialogComplete event. * - Removed use_server_data. This is now always on. * + Added functions for retrieving queue stats (number of files uploaded, queued, errors, etc) * + Added a file status property to the FileObject. This indicates, uploaded, error, waiting. * + Added a single file browser (user cannot select multiple files) * + Fixed bug (hopefully) caused if Flash call to JavaScript and in the callback JavaSCript calls to Flash * This only place this does not apply is to uploadStart. If you call in to Flash from uploadStart use a setTimeout to do it. * --------- Revision 6.2 ----------- * + Added API calls for changing all the changeable settings dynamically * = Fixed a bug in FileComplete event handler (in the SWF) that caused an error in Debug Players * and prevent the event from being called * + Added a setting (use_server_data_event) to indicate whether FileComplete or ServerData should be called. * The SWFUpload architecture requires that only one file upload success event can be called. * = Updated all the Demos, especially the Features Demo and the Forms Demo * --------- Revision 6 ----------- * - Removed the call to setUploadSettings in flashReady. This was a left over call that is unnecessary. * + Finished the parsing of post params during the init stage. This ommision was hidden by the call to setUploadSettings. * - Removed the flash_target_id setting. The Flash file should only ever be added to the body tag. * + Fixed (hopefully for good) another SWF race condition. IE executes the SWF very very early. The this.movieElement value should never be referenced. * The movie Element should always be retrieved using this.getMovieElement(). * --------- Revision 6 ----------- * + Ported to ActionScript 3. Revision 6 requires Flash Player 9. * = Fixed bug caused when cancelling single files. Would break any function that searched for a file_id. * - Removed the automatic cookie sending setting. Devs should just pass the value they want to send in the post_params * - Removed the query params settings (global and file specific). All params should be sent in the post_params * + Added post_params which adds post values to the file upload post. * + Added validate_files setting flag which causes the fileValidation event to be called before each file is uploaded. * + Added fileValidation event. Return false if validation fails and true if validation is successful. * + Added server_data parameter to the fileComplete event which returns any text that the upload script returns. * = Updated all demos to work with Revision 6 * + Added in-code file extension validation. Before a file is queued the extension is checked against the valid extensions. * Files the have invalid extensions cause the error event to be raised. * + Added 'file_post_name' setting that allows the post variable name containing the file data to be named something other than 'Filedata' * = Fixed a race condition in loadFlash where a cached flash movie would execute before this.movieElement could be assigned and loading would fail. * --------- Revision 5.2 ----------- * = A little more code cleaning and variable renaming * + Changed from an array queue to a FIFO queue. This eliminates the "current_index" and * should reduce some memory usage. * + Added out of order file uploading. Call StartUpload(/file_id/). * + Added custom query_string parameters in addition to the cookies * + Added the ability to modify the URL, cookies, params and send to flash * + Added per file query_string params * + Added files queued limit. Sometimes you may want the user to only queue one file at a time (or something) * + Fixed limits so a zero(0) value means unlimited. * --------- Revision 5 ------------- * = More code cleaning. Ported SWF to FlashDevelop. (Since my Flash Studio trial expired) * The port to FlashDevelop is a big deal. It significantly changes the code structure * and could introduce bugs. Also there have been reported issues with the FlashDevelop * version from swfupload.mammon.se: Doesn't start when reloading in IE. Doesn't start * in Firefox if the SWF file is visible because of a page scroll. * + I fixed the Firefox issue by removing the wmode attribute from the embed object. * + I cannot reproduce the IE issue on my local machine (although I can reproduce it at swfupload.mammon.se) * + Event Handlers are now attached to the SWFUpload javascript object. The SWF file * now calls the handlers in the context of the SWFUpload object which means the "this" * object inside the handler refers to the proper SWFUpload instance. * + Tested and Fixed upload target cookie attachment * = Cleaned up / renamed everything for clarity and consistancy * + File queuing is now subject to the upload limit. If the user attempts to queue more files * than allowed an error is returned and the files are not queued. * + Fixed misc bugs and text encodings. * + Added more debug info for the SWF file. * + SWF file now obeys the debug setting. * + Added SetUploadTargetURL function that allows you to "dynamically" change the upload target * + Added error code for zero byte file uploads which always return an IO error. The files are now rejected * instead of being uploaded. * --------- Revision 4 ------------- * = Cleaned up code. Added comments. Reorganized. Added more try..catches. Removed old unused methods. * - Removed the 'create_ui' setting. The UI is now completely up to the developer. * + Added upload_backend_cookies setting. Can set a string, or array of cookie names. These values will be * passed as part of the upload_backend url * * = Changed QueueComplete event to only fire if at least one file has been successfully uploaded. * + Added "Stop Upload" feature. * = Revised the FLA file to clean things up, better handle errors, etc. * = Fixed a bug where cancelling the first upload would cause the remaining uploads to fire before calling * "startUpload". This change is in the FLA. * * + Fixed a bug in the upload.swf that prevented further file processing after an error is returned. * + Added uploadLimit variable. Only complete uploads are counted. Once the limit is reached the flash * movie will not upload any more files. (The ability to select or queue many files is not affected * by the upload limit) * + Added cancelQueue and cancelUpload methods. * + Added ID property to the FileObj in the upload.swf * + Added Upload and Queue settings * + Added methods for generating the flash HTML and inserting it into the DOM. * - Removed SWFObject * + Updated the upload.swf and added the "flashReady" event. This will only call back * for Flash 8 and above. With this we don't need a flash version detect script. * The script initializes the Flash then waits for the Callback to init the UI. * + Added seperate ui_target, degraded_target, create_ui settings. This allows fine control * over what parts of the GUI the script displays and hides * * + Changed from a Static Class to an Instance (changed code/class structure) * + Added "flash_version" setting. When set to zero the version check is skipped * + Added Debug Console. The Instance class can't do document.write. * = De-obfuscated SWFObject a bit * - Removed standalone mode. * + Added "ui_target" setting. When non-blank the link is added. * + Added "flash_target" setting. When blank the flash is appended to the tag * = This fixes ASP.Net not allowing the flash to be added to the Form * + Added error checking to the callSWF method * * -------- -------- -------- -------- -------- -------- -------- -------- * SWFUpload 0.7: Flash upload dialog - http://profandesign.se/swfupload/ * SWFUpload is (c) 2006 Lars Huring and Mammon Media and is released under the MIT License: * http://www.opensource.org/licenses/mit-license.php * -------- -------- -------- -------- -------- -------- -------- -------- * SWFUpload 0.7: Flash upload dialog - http://profandesign.se/swfupload/ * * VERSION HISTORY * 0.5 - First release * * 0.6 - 2006-11-24 * - Got rid of flash overlay * - SWF size reduced to 840b * - CSS-only styling of button * - Add upload to links etc. * * 0.7 - 2006-11-27 * - Added filesize param and check in SWF * * 0.7.1 - 2006-12-01 * - Added link_mode param for standalone links * if set to "standalone", createElement("a") won't run. * - Added link_text param if css isn't needed. * - Renamed cssClass to css_class for consistency * */
