Upload specific files or all the files in the queue.
The ID of the file you would like to upload. The easiest way to get the fileID of a queue item is to use the id attribute of the queue item you want to upload. To upload multiple files, add each fileID as an argument. If ‘*’ is passed as the first and only argument, all files in the queue will be uploaded.
<input type="file" name="file_upload" id="file_upload" />
