This document provides information about the Uploadify plugin, which allows users to add single or multiple file upload functionality to a webpage. It works by using jQuery, Flash, and a backend script. The plugin is easy to implement by calling a jQuery function and linking necessary files. It has many configuration options to customize aspects like the uploader, script paths, queue size, and more.

- 1. Uploadify v2.1.0 息2009 by Ronnie Garcia Developed by Ronnie Garcia and Travis Nickels www.uploadify.com www.ronniesan.com WHAT IS IT? This plug-in allows you to change any element with an ID attribute on your page into a single or multiple file upload tool. The plug-in uses a mix of JQuery, Flash, and a backend upload script in the language of your choice to send files from your local computer to your website server. HOW DO I IMPLEMENT IT? Implementation of the plug-in is very easy and only relies on one JQuery function call to initiate. 1. Download the latest zip package from http://www.uploadify.com 2. Extract the files and upload them to your server (for the most basic installation, upload all files to the same folder). 3. Link the jQuery script, swfobject script and the Uploadify plug-in to the page you will be using it on. You can do so with the following code in the <head> section of your page: <script type="text/javascript" src=/slideshow/uploadifyv2-10manual100417052228phpapp01/26571336/"/path/to/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="/path/to/swfobject.js" <script type="text/javascript" src="/path/to/jquery.uploadify.v2.1.0.min.js"></script> 4. Add the call to the plug-in using the $.ready event in the <head> section of your page: <script type="text/javascript"> $(document).ready(function() { $('#someID').uploadify({ 'uploader': '/path/to/uploadify.swf', 'script': '/path/to/uploadify.php', 'folder': '/path/to/uploads-folder', 'cancelImg': '/path/to/cancel.png' }); }); </script> When the document is done loading, the elements that the function was called against will be hidden and replaced by the browse button. The component is now ready to use on your page.
- 2. AVAILABLE OPTIONS uploader The path to the uploader.swf file. For absolute paths prefix the path with either '/' or 'http' Default = 'uploader.swf' script The path to the backend script that will be processing your uploaded files. For absolute paths prefix the path with either '/' or 'http' Default = 'upload.php' checkScript The relative path to the backend script that will check if the file selected already resides on the server. No Default. 'check.php' is provided with core files. scriptData An object containing name/value pairs of additional information you would like sent to the upload script. {'name': 'value'} fileDataName The name of your files array in the upload server script. Default = 'Filedata' method new Set the method for sending scriptData to the backend script. Either 'GET' or 'POST'. Default is set to 'POST'. scriptAccess The access mode for scripts in the flash file. If you are testing locally, set to 'always'. Default = 'sameDomain' folder The path to the folder you would like to save the files to. Do not end the path with a '/'. For absolute paths prefix the path with either '/' or 'http'. Note server security issues with trying to upload to remote destinations. queueID new The ID of the element you want to use as your file queue. By default, one is created on the fly below the 'Browse' button. queueSizeLimit new The limit of the number of items that can be in the queue at one time. Default = 999. multi Set to true if you want to allow multiple file uploads. auto Set to true if you would like the files to be uploaded when they are selected. fileDesc The text that will appear in the file type drop down at the bottom of the browse dialog box. fileExt A list of file extensions you would like to allow for upload. Format like '*.ext1;*. ext2;*.ext3'. fileDesc is required when using this option. sizeLimit A number representing the limit in bytes for each upload. simUploadLimit changed A limit to the number of simultaneous uploads you would like to allow. Default:1. buttonText The text you would like to appear on the default button. Default = 'BROWSE' buttonImg The path to the image you will be using for the browse button. hideButton Set to true if you want to hide the button image.
- 3. rollover Set to true if you would like to activate rollover states for your browse button. To prepare your browse button for rollover states, simple add the 'over' and 'press' states below the normal state in a single file. See below for an example: *Mouseover events are inconsistent in Flash 9 so you may see a short lag when using the rollover option. width The width of the button image / flash file. Default = 30 height The height of the button image / flash file. If rollover is set to true, this should be 1/3 the height of the actual file. Default = 110 wmode Set to transparent to make the background of the flash file transparent. If set to transparent, the flash file will be at the top-most layer of the page. By omitting the buttonImg option and setting wmode to transparent, the entire flash file will be transparent, allowing you layer content below it or style the button using CSS.
