I want to be able to check that the user did not press the submit button
without first choosing a file.
I've got:
<--- ChooseFile.cfm --->
<form action="index.cfm?go=BatchUpdate" method="post"
enctype="multipart/form-data" name="myForm">
<tr><td><input type="file" name="UpdateFile" size="36"></td></tr>
<tr><td><br><input type="submit" value="submit"></td></tr>
</form>
I validate to see if there is an empty field with:
<--- ValidateFile.cfm --->
<cfif FORM.UpdateFile IS " ">
<cflocation url="ChooseFile.cfm?Message=1">
</cfif>
<cfif CGI.CONTENT_LENGTH EQ 0>
<cflocation url="ChooseFile.cfm?Message=1">
</cfif>
But I can't catch the empty field or zero lenght file thereby getting an
error message:
<--- Error Message --->
Error processing CFFILE
No data was received in the uploaded file '\.' Saving empty (zero-length)
files is prohibitted. Please make sure you specified the correct file.
