URL function call with variables

[tachekent]

I understand how to call a function from a URL as in:

www.example.com/index.php?function=useme

but if I use this address as the action in a form POST, the function seems to be called before the form variable is available in HTTP_POST_VARS (I need this variable inside the function), giving me the error:

Undefined variable: HTTP_POST_VARS

if I use GET then function is deleted from the URL before sending

is this strange? or am I doing something wrong.

(I'm using this to make a database management form, so SUBMIT sends a textfield name to a CREATEDB function)

you cant specify parameters in a forms action.
use hidden fields for this:

<form action="www.example.com/index.php" method="post">
<input type=hidden name="function" value="useme">
and so on
</form>

that should do what you want
