File Upload Control


Create a file upload control that can be used to upload one or more files. Does not work on older browsers, including Internet Explorer 9 and earlier.


Whenever a file upload completes, the corresponding input variable is set to a dataframe. This dataframe contains one row for each selected file, and the following columns:

The filename provided by the web browser. This is not the path to read to get at the actual data that was uploaded (see datapath column).
The size of the uploaded data, in bytes.
The MIME type reported by the browser (for example, text/plain), or empty string if the browser didn't know.
The path to a temp file that contains the data that was uploaded. This file may be deleted if the user performs another upload operation.
