The only difference is that $_REQUEST includes $_COOKIE, isn't it?
I don't see what this would have to do with Ajax in other words
There must be something I'm missing?

You're probably right and there's nothing subtle going on, but every single Ajax tutorial / bit of documentation uses $_REQUEST and I've been slavishly following them at least until I've got everything working And if I am, then probably other people will too.
Actually I did experiment with using $_POST instead this morning and it didn't work but I don't know enough about all that sort of stuff to know whether it should have done or if it didn't why not.
I haven't bothered to look at Ajax stuff in detail yet (will be coding some soon). However, you can make XMLHttpRequest use any method, as a quick search for docs revealed:
If you set method to POST then $_POST will work; if you set it to GET then $_GET will work. After a quick read through the docs, it seems to me that you can't set cookies using XMLHttpRequest (it always uses the browser standard ones) so there should be no situation [barring stupid ones where the same parameter is defined in different places] in which checking $_POST and $_GET together would not be equivalent to checking $_REQUEST from the point of view of input parameters. The PHP manual states that $_REQUEST is equal to $_POST + $_GET + $_COOKIE.
By the way if you want a second pair of eyes for fixing this stuff, I might be able to come over and take a look (since I need to know it soon anyway!).

I tried it with $_POST just now and it worked this time. Must have been doing something else wrong before... Maybe the coding standards will need to say not to use $_REQUEST so that people don't skip the cleaning up that they ought to do?
