I'm using a hidden button as shown in the following line to determine upon
entry (or re-entry) to the PHP file, whether or not to process the form
<input type="hidden" name="validateme" value="doit">
The form contains anchor tags to link to other pages. From this point of
view the form works perfectly. The problem is that, when the user goes back
to this page later on, the "validateme" posted variable does not expire, so
the form tries to reprocess the form, even though there is no form to show.
My question is how can I reset the validateme ...
