cffile - wrong file type error message

[etman]

I'm limiting a file upload to either a .jpg or a .jpeg file. If someone tries
to upload anything other than a file with one of those extensions you get an
ugly CF error window. Is it possible to instead detect that the person is
trying to upload something other than what is allowed, and show my own error
message (or set the value of a variable so that I can reload the page and show
a 'nice' error message. Thanks in advance, Rob

You could use
<cftry>
<cfcatch type="ANY">
</cfcatch>
</cftry>

In addition to cftry/cfcatch, write a regular expression to file the extension so you can validate that it's only .jpg or .jpeg. Then you can handle this exception with your custom message.
