Hi

I'm trying to write a small foreach loop that will empty all POST vars received by the page

this doesn't work :

	

foreach($HTTP_POST_VARS as $k => $var){
$k = "";
}

so I'm obviously overlooking a basic thing ...

has anyone got a simple way of doing this ?

thanks

    oops i posted the wrong bit :

    	foreach($HTTP_POST_VARS as $k => $var){
		$HTTP_POST_VARS[$k] = "";
	}

      Eh, why do you want to do this? It depends on what you mean by empty, but it could be:

      foreach ($_POST as $key => $value) {
    unset($_POST[$key]);
}

      I see it as rather pointless.

        I suppose

        $_POST = array();

        would work too if you just want to get rid of all of them

          so that when the form is sent and the page is re-displayed with the success message, all of the form fields are empty

          and your solution works fine

          thank you

            ah yes - an even simpler solution, leatherback

            thanks

              Okay, that sounds fine, if you really do intend to display the form after processing.

              and your solution works fine

              I think leatherback's solution should work better.
