You 're thinking of something like this, aren't you?
<A href="javascript:document.forms[0].submit();"> ... </A>

You should notice that PHP is running on the server and all variable references are
resolved on the server side before it releases the HTML content.
I think what you need is some Javascript:
<A href="javascript:go_where_my_variable_says('this.php');">this page</a>
<SCRIPT LANGUAGE="JavaScript">
<!--
function go_where_my_variable_says(where)
{
document.forms[0].action = where;
/* here you can manipulate your variables on the client side, before submit the
form,
ie. clear input box named 'input1' :
document.forms[0].input1 = ''; */
document.forms[0].submit();
}
//-->
</SCRIPT>
