Re: Proper returntype of a cfc
You would need to return it as a struct. then just reference any parts of the struct that contain the data you want. I have one cfc that returns a struct of arrays...

Of course, that variable can contain other variables, multiple values, recordsets, etc. Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ Fig Leaf Software provides the highest caliber vendor-authorized instruction at our training centers in Washington DC, Atlanta, Chicago, Baltimore, Northern Virginia, or on-site at your location.

Re: Proper returntype of a cfc
Understand, I guess the proper terminology should be multiple values ? -- Ryan LeTulle On Fri, Jun 12, 2009 at 7:35 PM, Dave Watts dwa...@figleaf.com wrote: Is it a common/best practice to return multiple variables from a cfc?

Re: Proper returntype of a cfc
Understand, I guess the proper terminology should be multiple values ? Well then, it seems an odd question to ask. Return whatever data type reflects the best possible output for your function. If that's a query, return a query. If it's an array, return an array. If it's a structure, return a structure. There's nothing wrong with returning any of these, if that's what you want to get back.

Re: Proper returntype of a cfc
Only odd to you because you are all knowing. For the most part I have always returned either a query or 1 variable.

Re: Proper returntype of a cfc
Only odd to you because you are all knowing. I wish! But calling functions in CF is basically the same as calling functions in other languages. You provide a list of inputs, and get a single return value.

Re: Proper returntype of a cfc
@dave I started using cfcs after reading a Ben Forta article a couple of years ago where he said at least use cfcs for querys and you should never output to the screen from cfcs. For the most part that is what I have used them for. Unfortunately, I never really advanced further than that with cfcs. Otherwise, I get it done without 'em. I want to do better. :) -- Ryan LeTulle On Fri, Jun 12, 2009 at 7:57 PM, Dave Watts dwa...@figleaf.com wrote: Only odd to you because you are all knowing. I wish!

Re: Proper returntype of a cfc
Consider returning an object (another CFC), rather than a struct. In some cases a struct works well, but if you return an object you have better documentation as to what it returns, rather than with a struct with unknown keys. You can also setup default values in the CFC. -- Pete Freitag http://foundeo.com/ - ColdFusion Consulting Products http://petefreitag.com/ - My Blog ~| Want to reach the ColdFusion community with something they want?
