Hmm...either i don┤t really get what you mean, or you missed the problem.

This is the situation:

I have a form which results is to be inserted in a db. When the form is
submitted the page calls itself and does a db INSERT based on if a couple of
statements is true - otherwise it displays a proper error message.

So far everything is fine and is working like a charm.
But:

I want a redirection after a successfull db INSERT. After the INSERT is made
(which is what the page is for) i set a variable, $done, to 1.
Right now i only use $done to display a message at the bottom of the screen
saying that the INSERT worked. But i want the page to redirect itself as
soon as $done is set to 1.

The problem i have is: I can only send headers (wich i use for redirection -
right??) at the top of the page - before all the other code. But since $done
is set far down in the code, after my form and db-statements, the header
will never know when to be sent.

Is there a way of calling a headerfunction in the top of the page?
