Session

[Guest]

I am trying to set a session to log attempts, I have a page that displays an Identity question, I need to track how many times the y try to answer it. Can somebody help me. Here is my code.

<cfparam name="session.attempts" default="0">
<cfset session.attempts = StructNew()>
<cfset session.attempts=session.attempts+1>

><cfset session.attempts = StructNew()>
><cfset session.attempts=session.attempts+1>

You cannot use "+" on a structure. If session.attempts is a simple number, remove this line.
<cfset session.attempts = StructNew()>

You might also want to lock the increment statement to prevent race conditions.
<cflock ...>
<cfset session.attempts=session.attempts+1>
</cflock>

so would it look like this?

<cflock scope="session" type="exclusive" timeout="5">
<cfset attempts = session.attempts>
<cfset session.attempts=session.attempts+1>
</cflock>

><cfset attempts = session.attempts>
It doesn't look like you're doing anything with the variable "attempts". Try

<cflock scope="session" type="exclusive" timeout="5">
<cfparam name="session.attempts" default="0">
<cfset session.attempts=session.attempts+1>
</cflock>

ok cool, let me ask you this when this page is called is that when the session starts? and does the session.attempts add 1 everytime the page is called during this session?

>when this page is called is that when the session starts?
Maybe. It depends. "A new session is created as a result of a request that is not in an existing session". So calling that page might start a new session or it might not.

>and does the session.attempts add 1 everytime the page is called during this session?
Yes. I'm not sure that's what you want. For counting retry attempts I usually use a cfif to check whether the value should be incremented.

<cfif ... some condition>
<cflock..>
...increment value here
</cflock>
</cfif>

Thanks for your help, I have a set of IdentityQuestion in my db and I am displaying them randomly, and I am only allowing the user 3 times to answer the question, I will use this session.attempts to track it.
