* 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 <body> tag
|
|
* = This fixes ASP.Net not allowing the flash to be added to the Form
|
|
* + Added error checking to the callSWF method
|
|
