RE: [CFCDev] Detecting arguments passed by CFINVOKEARGUMENT?

Title: Message

It looks like you pass this to New

StudentNumber=foo

FistName=foo

LastName=foo

notice your new method does,

that means arguments will be a join of what you sent and what you defined - so you should have this in arguments:

Username

Password

StudentNumber

StudentSequence

FirstName

LastName

The last two weren't defined, but your passed in in anyway.

That's certainly what I would expect you to see - but you saw:

FirstName Howard
LastName Fore
PASSWORD [undefined struct element]
STUDENTNUMBER AC0230903
STUDENTSEQUENCE 0
USERNAME [undefined struct element]
FIRSTNAME Howard
LASTNAME Fore
PASSWORD [empty string]
STUDENTNUMBER AC0230903
STUDENTSEQUENCE 58314
USERNAME [empty string]

Very odd. You have discovered a 'magical' structure that has keys w/ the same name in them it seems. I'd say it was case - but notice you have two PASSWORDs, and student numbers.

I'm confused - are you saying that when you call method foo, the values

That's exactly the behavior I'm seeing. Code follows:

_newUserLookup.cfc (controller script to handle form input):
<cfsilent>

<cfinvoke
component = "#application.stConfig.CFCOMPONENTS_PREFIX#com.ashworthcollege.student"
method = "new"
returnVariable = "student">
<cfinvokeargument
name="StudentNumber"
value="#ATTRIBUTES.StudentNumber#">
<cfinvokeargument
name="FirstName"
value="#ATTRIBUTES.FirstName#">
<cfinvokeargument
name="LastName"
value="#ATTRIBUTES.LastName#">
</cfinvoke>

<cfif student.studentNumber NEQ 0>

<cfset session.student = student>
<cflocation url="" addToken="no">
<cfelse>

<cflocation url="" addToken="no">
</cfif>
</cfsilent>

Student.cfc:
<cfcomponent displayname="Student">

<cfproperty name="FirstName" type="string">
<cfproperty name="LastName" type="string">
<cfproperty name="StudentNumber" type="string">
<cfproperty name="StudentSequence" type="numeric" default="0">
<cfproperty name="UserName" type="string">
<cfproperty name="Password" type="string">

<cffunction name="new" output="false">
<cfargument name="UserName" type="string" required="false">
<cfargument name="Password" type="string" required="false">
<cfargument name="StudentNumber" type="string" required="false">
<cfargument name="StudentSequence" type="numeric" required="false" default="0">

<cfset studentData = StructNew()>

<cfquery name="qFindStudent" maxrows="1" datasource="#application.stConfig.DSN#">
select
s.FirstName as FirstName,
s.LastName as LastName,
s.StudentSequence as StudentSequence,
s.StudentNumber as StudentNumber,
s.UserName as UserName,
s.Password as Password
from
Students s
where


<cfif
StructKeyExists(arguments,"FirstName") and
StructKeyExists(arguments,"LastName") and
StructKeyExists(arguments,"StudentNumber")>
s.FirstName = <cfqueryparam value="#arguments.FirstName#" cfsqltype="CF_SQL_VARCHAR">
and
s.LastName = <cfqueryparam value="#arguments.LastName#" cfsqltype="CF_SQL_VARCHAR">
and
s.StudentNumber = <cfqueryparam value="#arguments.StudentNumber#" cfsqltype="CF_SQL_VARCHAR">
</cfif>


<cfif
StructCount(arguments) EQ 1 and
StructKeyExists(arguments,"StudentSequence")>
s.StudentSequence = <cfqueryparam value="#arguments.StudentSequence#" cfsqltype="CF_SQL_INTEGER">
</cfif>

<cfif
StructCount(arguments) EQ 2 and
StructKeyExists(arguments,"UserName") and
StructKeyExists(arguments,"Password")>
s.UserName = <cfqueryparam value="#arguments.UserName#" cfsqltype="CF_SQL_VARCHAR">
and
s.Password = <cfqueryparam value="#arguments.Password#" cfsqltype="CF_SQL_VARCHAR">
</cfif>
</cfquery>
<cfif qFindStudent.recordcount eq 1>
<cfset studentData.FirstName = trim(qFindStudent.FirstName)>
<cfset studentData.LastName = trim(qFindStudent.LastName)>
<cfset studentData.StudentSequence = trim(qFindStudent.StudentSequence)>
<cfset studentData.StudentNumber = trim(qFindStudent.StudentNumber)>
<cfset studentData.UserName = trim(qFindStudent.UserName)>
<cfset studentData.Password = trim(qFindStudent.Password)>
<cfset studentData.CFCArguments = arguments >
</cfif>
<cfreturn studentData>
</cffunction>

And finally, in newUserProfileEdit.cfm I have a <cfdump var="#session.student#"> which produces this (view in monospaced font to make sense):

struct
CFCARGUMENTS struct
FirstName Howard
LastName Fore
PASSWORD [undefined struct element]
STUDENTNUMBER AC0230903
STUDENTSEQUENCE 0
USERNAME [undefined struct element]
FIRSTNAME Howard
LASTNAME Fore
PASSWORD [empty string]
STUDENTNUMBER AC0230903
STUDENTSEQUENCE 58314
USERNAME [empty string]
