I'm not sure if this is specifically a PHP problem, but here we go. Is =
there a way to clear the POST variables when the user refreshes a page? =
=
Specifically, my webpage POSTs a form to update or delete a record from =
=
the database -- it POSTs to itself, however. But if the user then clicks=
=
the browser's refresh button, it will try to delete or modify a =
non-existent record. I would like, if the users presses the refresh =
button, that PHP processes the page as no POST variables are set. I have=
a =
button on the page entitled "Reload" that executes a short Javascript: =
onclick=3Dwindow.location=3D<? echo PHP_SELF; ?> which accomplishes the =
=
desired effect. But it tries to resend the POST information if the brows=
er =
refresh button is clicked.
I read something somewhere that seemed to imply this could be done with =
=
PHP sessions? Is this the way to go? If so, how?
Thanks for any help.
