I have a query that supposed to get the value from a multiple select dropdown and update only those records in a database. I also want it to add a sequence number based on the order the option shows in in a dropdown. Query below

<cffunction name="setFeaturedCourse" returntype="void" output="false">
            <cfargument name="id" type="numeric" required="yes">
            <cfargument name="featuredcourse" type="string" required="yes">
            <cfquery name="updateFeaturedCourse" datasource="#application.dsName#" username="#application.dsUserName#" password="#application.dsPassword#">
                  UPDATE courses SET
                        featuredcourse = '#arguments.featuredcourse#'
                        
                  WHERE auto_no = '#arguments.id#'
            </cfquery>
            <cfreturn>
      </cffunction>

I'm afraid that most of us are not going to find the information we need to answer your question in this HTML and ColdFusion code.  What we need is:

What you want to do.
Sample Before data
The data you have to work with (what you would submit to the query)
Sample After data

If we have this, we can examine the SQL code and ensure it performs as needed or show you code that should do what is needed.

If the question is about ColdFusion, we really are not your best resource.  Same with HTML.

I need to update multiple records with a new featuredcourse value based on what options are listed in the featuredcourses listbox. I have the values correctly, for me its a sql issue in how to get the values passed to the cfc.

Okay - now we have the "what you want to do" piece clearly.

Can you provide examples of data prior to the update, the information you have available, and what you want the data to look like after the update?

Thanks!

to submit to a cfc from a form you need to either specify the method directly

<form method="post" action="http:/someserver.com/com/youcfc.cfc?method=setFeaturedCourse'>


or set up a form handler (i prefer this way...i use it as a form switchbox)


<form method="post" action="http:/someserver.com/act/act_formhandler.cfm">

act_formhandler.cfm
--------------------------

<cfif isdefined('form.submitbtnname')>

<cfinvoke method = "setFeaturedCourse"
                  Component = "com.yourCFC"
                  returnVariable = "whatever">
<cfinvokeargument name="featuredcourse" value="#form.featuredcourse#">
<cfinvokeargument name="Order" value="#form.displayorder#">
            </cfinvoke>

</cfif>


you'll also have to do some coding in the cfc to break the featuredcourse list returned by the multiple selections and match that to the displayorder list
