Advanced Uploader Example With Additional POST Variables and Server Data Return

This example demonstrates how the Uploader can be rendered as a transparent layer on top of your own UI, and how custom variables can be added to the upload"s POST request. In this example, the server-side script also echoes the POST variables accompanying the upload; we retrieve the data returned by the server and display it to the user.

Note: The YUI Uploader Control requires Flash Player 9.0.45 or higher. The latest version of Flash Player is available at the <a href="http://www.adobe.ru/go/getflashplayer">Adobe Flash Player Download Center</a>.

Note: The YUI Uploader Control requires the uploader.swf Flash file that is distributed as part of the YUI package, in the uploader/assets folder. Copy the uploader.swf to your server and set the YAHOO.Uploader.SWFURL variable to its full path.

Note: This example uses a server-side script to accept file uploads. The script used does not open or store the file data sent to it. It also does not store the accompanying POST variables, but it does echo them in the response relayed back to the sender of the request. When trying out the example, do not send any sensitive or private data. Do not exceed file size of 10 MB. </div> <style>

  1. selectFilesLink a, #uploadFilesLink a, #clearFilesLink a {
color: #0000CC; background-color: #FFFFFF; }
  1. selectFilesLink a:visited, #uploadFilesLink a:visited, #clearFilesLink a:visited {
color: #0000CC; background-color: #FFFFFF; }
  1. uploadFilesLink a:hover, #clearFilesLink a:hover {
color: #FFFFFF; background-color: #000000; } </style> 
   Set custom values for a couple POST vars:

   var1: <input type="text" id="var1Value" value="var1 default value" />

   var2: <input type="text" id="var2Value" value="var2 default value" />




   Progress: <input type="text" cols="50" id="progressReport" value="" readonly />

Advanced Uploader Example With Cookie Submission as a POST variable

 <p>One of the major limitations of the Flash-based uploader is that it cannot use browser cookies to authenticate file uploads. In this example, we provide sample code that demonstrates how to attach the page cookie as a variable in the body of the upload POST request, rather than in the header. The code will generate a cookie with a username and the last uploaded file name, and send the value along with the file that needs to be uploaded. We also provide a sample backend script that accepts the file upload and echoes the POST variables accompanying the upload (thus ascertaining that the cookie data was received by the server).  We show how we can retrieve the data returned by the server and display it to the user.</p>

<p>Note: This is a static example, which means that you will not be able to try it out on our server. You will need to set up the code on your own server in order to run it.</p> <p>Note: The YUI Uploader Control requires Flash Player 9.0.45 or higher. The latest version of Flash Player is available at the <a href="http://www.adobe.ru/go/getflashplayer">Adobe Flash Player Download Center</a>.</p> <p>Note: The YUI Uploader Control requires the uploader.swf Flash file that is distributed as part of the YUI package, in the uploader/assets folder. Copy the uploader.swf to your server and set the YAHOO.Uploader.SWFURL variable to its full path.</p> <p>Note: this example is static, which means that it will not work properly on this page.

Simple Uploader Example With Button UI

 <p>This example is a demonstration of the <a href="../../uploader/">YUI Uploader Control</a>"s features.</p>

<p>Note: The YUI Uploader Control requires Flash Player 9.0.45 or higher. The latest version of Flash Player is available at the <a href="http://www.adobe.ru/go/getflashplayer">Adobe Flash Player Download Center</a>.</p> <p>Note: The YUI Uploader Control requires the uploader.swf Flash file that is distributed as part of the YUI package, in the uploader/assets folder. Copy the uploader.swf to your server and set the YAHOO.Uploader.SWFURL variable to its full path.</p> <p>Note: This example uses a server-side script to accept file uploads. The script used does not open or store any data sent to it. Nonetheless, when trying out the example, do not send any sensitive or private data. Do not exceed file size of 10 MB.

<style type="text/css"> 

 .uploadButton a, .clearButton a {
   display:block;
