HOWTO: Handle situation when Adobe Flash is not installed on client machine

how to redirect to another page with form-based file upload if Adobe Flash is not installed:

Code:

<script type="text/javascript">
		// get installed flash player version
		// returns an array of three numbers: major version, minor version, revision number.
		var version = $au.flashDetector.detectVersion();
		// Image Uploader Flash requires Flash Player 10 or higher
		if (version[0] >= 10) {
			var uploader = $au.imageUploaderFlash({
				id: 'Uploader1',
				width: '600px',
				height: '500px',
				flashControl: {
					codeBase: 'scripts/aurigma.imageuploaderflash.swf'
				}
			});

			uploader.writeHtml();

		} else {
			if (window.location.search != '?noredirect') {
				window.location = 'simple_upload.htm';
			}
		}
</script>


Here is sample code of HTML form upload on the simple_upload.htm page:

Code:

 <form id="form1" action="simple_upload.htm" enctype="multipart/form-data">
	<input id="File1" type="file" /><input id="Submit1" type="submit" value="Upload" />
</form>



how to display form with file input on the same page instead of Flash Uploader:

Code:

 <!-- Use display:none style to hide this form -->
	<div id="simple_upload" style="display: none">
		<form id="form1" action="demo2.htm" enctype="multipart/form-data">
		<input id="File1" type="file" /><input id="Submit1" type="submit" value="Upload" />
                </form>
	</div>
	<script type="text/javascript">
		// get installed flash player version
		// returns an array of three numbers: major version, minor version, revision number.
		var version = $au.flashDetector.detectVersion();
		// Image Uploader Flash requires Flash Player 10 or higher
		if (version[0] >= 10) {
			var uploader = $au.imageUploaderFlash({
				id: 'Uploader1',
				width: '600px',
				height: '500px',
				flashControl: {
					codeBase: 'scripts/aurigma.imageuploaderflash.swf'
				}
			});
			uploader.writeHtml();
		} else {
			document.getElementById('simple_upload').style.display = '';
		}
</script>
