The problem with this is that the CFML code executes on the server before
the HTML form is sent to the client. Form variables only exist after a form
has been posted to the server, and are then available in the action page.
So, you could do something like this:
<!-- form.cfm -->
<html>
<head>
<title>Form</title>
</head>
<body>
<form action="formaction.cfm" method="post">
<select name="myselect">
<option value="0">none
<option value="1">employee
<option value="2">customer
</select>
<input type="submit">
</form>
</body>
</html>
<!-- formaction.cfm -->
<cfif form.myselect is "1">
<cflocation url="employee.cfm">
<cfelseif form.myselect is "2">
<cflocation url="customer.cfm">
</cfif>
Note that this requires two trips to the server; one to retrieve the form,
and one to process the form submission. You could do something with
JavaScript instead which would be more efficient.
There was another problem which I should point out. In your conditional
logic, you did this:
> <cfif "form.select" is "2">
If you wrap something in quotes, it's a literal string, rather than a
variable. You could do this:
<cfif "#form.select#" is "2">
which would evaluate the variable within the literal string. Or, better yet,
you could do this:
<cfif form.select is 2>
which doesn't require any evaluation.
