Re: [flexcoders] Using Auth.cfc from CF Wizard

Returning true/false to flex, like you are doing, tells Flash that the authentication was successful and to do what ever you want to do next at the client. However, with the code you have you haven't told CF the user is authenticated. So if you made some other call that requires roles based security in CF it would fail.

What you want to do is add a <CFLOGIN> tag to the method.

hth,

--nimer

something like this:

<cffunction name="login" access="remote" returntype=" boolean">
<cfargument name="user" required="yes" />
<cfargument name="password" required="yes" />

<cfset var qRead="">

<cfquery name="qRead" datasource=" tiomkin">
    SELECT UserName, UserPassword
    FROM USERS
    WHERE UserName = <cfqueryparam cfsqltype="CF_ SQL_VARCHAR" value="#arguments. user#" />
    AND UserPassword = <cfqueryparam cfsqltype="CF_ SQL_VARCHAR" value="#arguments. password# " />
</cfquery>

<cflogin>

<cfloginuser name="#arguments.user#" password="#arguments.password#" roles="authenticatedUser"/>

    </cflogin>

    <cfif qRead.recordcount gt 0>
        <cfreturn true>
    <cfelse>
        <cfreturn false>
    </cfif>
</cffunction>

Subject: [flexcoders] Using Auth.cfc from CF Wizard

Hi all,
Does anyone have a working example of auth.cfc (the file that gets
generated when using the CF Wizard? I thought the code below would be
sufficient but its still not working. Any suggestions?

CODE:

AUTH.CFC:
<cffunction name="login" access="remote" returntype=" boolean">
<cfargument name="user" required="yes" />
<cfargument name="password" required="yes" />

<cfset var qRead="">

<cfquery name="qRead" datasource=" tiomkin">
SELECT UserName, UserPassword
FROM USERS
WHERE UserName = <cfqueryparam cfsqltype="CF_ SQL_VARCHAR"
value="#arguments. user#" />
AND UserPassword = <cfqueryparam cfsqltype="CF_ SQL_VARCHAR"
value="#arguments. password# " />
</cfquery>

<cfif qRead.recordcount gt 0>
<cfreturn true>
<cfelse>
<cfreturn false>
</cfif>
</cffunction>
