[ web_request->fileUploads ]
The [web_request->fileUploads] method returns information about any HTTP file uploads given to the current request. This method returns a sequence of containers (usually but not always a staticarray). Each of these sub-containers contains a sequence of pair values. Each pair contains as its ->first member the name of the file upload related value (the keys; listed below) and as its ->second member the value itself.
Each file upload will have pairs containing the following keys:
- contenttype - The content type of the file
- fieldname - the name of the file input field
- filename - the original name of the file as it was sent to the server
- tmpfilename - the path on the server to which the file was temporarily uploaded
- filesize - the size of the file in bytes
Each uploaded file is written to a temporary directory and the path to that temporary file is provided (as 'tmpfilename'; shown above). At the end of the request, all uploaded files are deleted. Any files that are meant to be kept should be moved or copied from the temp directory to their intended destinations.
