How do I determine whether a user is accessing a feed?

I’m trying to work out how to determine whether or not a user has requested an RSS or ATOM feed from within a plugin. I thought that checking gps('rss') and gps('atom') would do the trick, but I seem to be missing something. I have code that looks something like this:

if (gps('rss') || gps('atom')) {                  
	Process content appropriately for a feed...
} else {                                         
	...otherwise process content normally. 
} 

But it always defaults to the else condition. Can anybody shed a little light on how I can work this out reliably?

Thanks,
Michael

I think you need to do it as part of a ‘pretext’ callback.

Yep, Steve is correct.

Steve & Mary –

Thanks for the guidance – now I’m halfway there. It looks like I can pick up gps('rss') and gps('atom') in a pretext callback, but only when using messy URLs.

I’ll do some more digging to see if I can work it out, but if you have any ideas, I’d be happy to hear them.

Thanks,
Michael

Re: How do I determine whether a user is accessing a feed?

Actually, I think I’ve sussed it out by poring through publish.php. I’ve got the following code which is doing the trick:

	global $permlink_mode;

if ($permlink_mode "messy") { $state = (gps('rss') || gps('atom')) ? "feed" : "site"; } else { $req = serverSet('REQUEST_URI'); extract(chopUrl($req)); $state = ($u1 ‘rss’ || $u1 == ‘atom’) ? “feed” : “site”; }

That seems reasonable to me. Do you forsee any issues with it?

Thanks again,
Michael

Nope, that should work okay. :)
