Get data about a file before you upload

im having a problem with my file upload script. I have a column in a database that has the total MB of stuff the person has uploaded. I want to be able to check how big the file is so it can check if it exceeds the total limit, but i can't ul the #filesize# variable before i use the cffile tag to upload it because the variable is inexistant. Is there any way to check the size of a users file before it is uploaded like another cffile tag i am unaware of???? thanks

There's no way to know anything about the file the user chose on the client side until it is uploaded, unless you use something like ActiveX, a Java applet, or Flash.

How can i create a maximum file size for upload??????? if i have that then i know a wayu i can do it

A Google search found me this, it might be close, if it works.

<cfset maximumFileSize = "1000000">
<CFIF Val(CGI.CONTENT_LENGTH) GT maximumFileSize>
The file you are attempting to upload exceeds the maximum allowable size of #maximumFileSize# bytes and cannot be uploaded to this server! Please choose a smaller file and try again.
<CFABORT>
</CFIF>
<CFFILE ACTION="UPLOAD"
FILEFIELD="FileToUpload"
DESTINATION="F:\mydir"
NAMECONFLICT="Overwrite">
