How can i check whether user did specify a file b4 clicking "Upload"? im not using any client-side scripting, so im using perl to check at the server end.
$ret = &ReadParse(\%cgi_data,\%cgi_cfn,\%cgi_ct,\%cgi_sfn);
this gave me a temp file everytime i click on upload .. even though the user did not specify any file to upload.
i also need to prompt user if the file they specify does not exist at all. Thanks!
