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 -- teodor
