I have a form that I am passing to a CFC for the action page. I store all of my datasource information in the application.cfm. I know that application variables don't carry over so I store my datasource info in an array (array[1] = datasource, array[2] = username, and array[3] = password). I know that normally with CFC's as action pages you use hidden fields in the form to pass values in, just as you would with arguments in regular CFC useage. I need to pass that array into my CFC. Is there another way to do it?

CODE

<cfform method="post" action="ticket_engine.cfc?method=addtick"  name="form1" skin="HALOBLUE" >
     <input type="hidden" name="method" value="addTick">
     <cfinput type="hidden" name="cat" value="#cat#">
     <cfinput type="hidden" name="username" value="#session.myusername#">
     <cfinvokeargument name="dbarray" value="#dbarray#">

Not sure what you mean by "application variables don't carry over" - if you are using CF8. I set my dsn in the Application.cfc in and call them from inside my component functions all the time - no need to pass them from inside a form.

I use application.cfm files so maybe that is it, but application.cfm variables don't carry over into cfc's.

Are you using CF7? If not - and you are using 8 and can convert to the Application.cfc - I would. I know the application level variables are read by my CFC's - I simply address them like #application.xxx# - so - say a function in my CFC runs a DB query - my query line looks like:
CODE

<cfquery datasource="#application.dsn#" name="blarg>
SQL STUFF HERE
</cfquery>


Also, when passing a form to a CFC function - I make the form action an actual page - and invoke the function from that page:

Example:

CODE

<cfform name="thisForm" method="post" action="procPage.cfm">



Then on procPage, I send the whole FORM structure to the CFC:

CODE

<cfinvoke component="cfcs/appUtil.cfc" method="formProc">
    <cfinvokeargument name="theForm" value="#FORM#">
</cfinvoke>


Then my function would expect an argument of a type="structure" and handle accordingly.

Does this make sense?

That does make sense. That will also let me push in application variables from my application.cfm. I know I need to convert over to using application.cfc, but my boss is still trying to use CF5 coding sometimes so he has no idea how to handle cfc's

OUCH! CF5?!?!?! Wow - are wew trying to be backwards compatible with an existing app written in 5 - or has the boss just not come up the learning curve from the CF5 days. I started back in the CF 3.1 days - and I know the curve is steep if you don't keep on top of it.
