Add media: ‘Choose file to upload’ stopped working on Windows

Okay, I think I’ve sussed out the cause of it by looking at the source code for the upload window, though I’ve not yet worked out the solution.

The ‘Choose file to upload’ button is (bizarrely) Flash based, and it automatically overides the HTML option to upload.

It has been reported that if people upgrade to Flash Player 10 then Flash buttons on the WordPress website might stop working for them. Which must be what has happened to my users… and why it still works for me, as I haven’t bothered updating my Mac’s Firefox to Flash 10 yet.

Now all I’ve got to do is try to find out how I can disable the Flash button for the upload! Any pointers anyone? It’s probably something to do with the following code, but I’ve got to try suss out where this is generated!

<script type="text/javascript">
<!--
jQuery(function($){
	swfu = new SWFUpload({
			upload_url : "http://www.ra3.org.uk/site/wp-admin/async-upload.php",
			flash_url : "http://www.ra3.org.uk/site/wp-includes/js/swfupload/swfupload_f9.swf",
			file_post_name: "async-upload",
			file_types: "*.*",
			post_params : {
				"post_id" : "-1231866471",
				"auth_cookie" : "admin|1232034367|f3fb643bb277f55bc24150b2f054dda1",
				"type" : "image",
				"tab" : "type",
				"short" : "1"
			},
			file_size_limit : "8388608b",
			swfupload_element_id : "flash-upload-ui", // id of the element displayed when swfupload is available
			degraded_element_id : "html-upload-ui",   // when swfupload is unavailable
			file_dialog_start_handler : fileDialogStart,
			file_queued_handler : fileQueued,
			upload_start_handler : uploadStart,
			upload_progress_handler : uploadProgress,
			upload_error_handler : uploadError,
			upload_success_handler : uploadSuccess,
			upload_complete_handler : uploadComplete,
			file_queue_error_handler : fileQueueError,
			file_dialog_complete_handler : fileDialogComplete,

			debug: false
		});
	$("#flash-browse-button").bind( "click", function(){swfu.selectFiles();});
});
//-->
</script>

<div id="flash-upload-ui">
	<input id="flash-browse-button" type="button" value="Choose files to upload" class="button" />

	After a file has been uploaded, you can add titles and descriptions.

</div>

<div id="html-upload-ui">

	<input type="file" name="async-upload" id="async-upload" /> <input type="submit" class="button" name="html-upload" value="Upload" /> <a href="#" onClick="return top.tb_remove();">Cancel</a>

	<input type="hidden" name="post_id" id="post_id" value="-1231866471" />
	<br class="clear" />
	</div>

Thanks and regards
