RE: [CFCDev] Detecting arguments passed by CFINVOKEARGUMENT?

Do you still see this symptom if you remove these lines of code from inside your function?

I use another check for string arguments to see if a value was actually passed:

<cfif len(arguments.userName)>where username=#arguments.username#</cfif>

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

                                FirstName                       Howard
