Jason,
If you don't expressly need it to run server side, you could always use a
simple little javascript check if you want.
*<script type="text/javascript">
function checkFileType() {
// for mac/linux, else assume windows
if (navigator.appVersion.indexOf('Mac') != -1 ||
navigator.appVersion.indexOf('Linux') != -1)
var fileSplit = '/';
else
var fileSplit = '\\';
var fileTypes = new Array('.zip', '.ZIP', '.jpg', '.JPG'); // valid
filetypes
var fileName = document.getElementById('UploadFile').value; //
current value in your file upload box
var extension = fileName.substr(fileName.lastIndexOf('.'),
fileName.length);
var valid = 0;
for(var i in fileTypes) {
if(fileTypes[i] == extension) {
valid = 1;
break;
}
}
if(valid == 1)
alert("The file to be uploaded is a PDF or ZIP file!");
else
alert("Invalid file type!"); *
*}*
*</script>*
