Very likely you used the optimized version of php.ini which has global
variables
registration off.
As for your question, I can tell you my tip:
I use
<input type="submit" name="action[login]" value="Login">
<input type="submit" name="action[signup]" value="SignUp">
and in the form do:
$PV = $HTTP_POST_VARS;
$action = isset ($PV['action']) ? key($PV['action']) :
'<default-action-here>';
switch ($action) { // allows lots of action w/o too many ifs and such
case 'login':
// login
break;
case 'signup':
// signup
break;
case 'default-action':
default:
// evetually
break;
}
so on.
hope it helps
ciao
