redirect issue

[Square1]

Hi all:

I have a form page that is submitting variables to a page that is to process the info and insert it into a DB. I have a simple IF condition:

	$idatearray=$_POST["idate"];

//Make sure at least 1 date is being posted

if (empty($datearray)){
		header( 'Location: ../msc/msc_errors.php?error=sansdate' ) ;
	}

So if someone submits the form with zero boxes checked then it redirects to an error page.

Even with the redirect an email script is still being processed below the redirect code. I would have though that a redirect ends any more functionality of the page it is coming from!

I am very new at PHP and have a lot to learn.

Any help appreciated!

So I did a little research and found that you need to write

exit();

after a redirect.

Is this standard practice?

You don't need to use exit after sending a 'Location' HTTP header, no, but it's commonly done in practice, yes, since you normally don't want any PHP code to be executed after you've made the decision to redirect the user.

EDIT: Just to clarify; calling header() simply adds/sets/replaces an HTTP header in the list of headers that the webserver will send in response to the client.

Naturally, this won't stop PHP from executing the rest of your code. If that's what you want, then you have to tell PHP to stop - namely by using [man]exit/man.
