Question

用php+dw做一个注册页面，点击注册却不能跳转，但注册信息已经在数据库已经有了，求大神解答

// *** Redirect if username exists
$MM_flag="MM_insert";
if (isset($_POST[$MM_flag])) {
$MM_dupKeyRedirect="regfail.php";
$loginUsername = $_POST['username'];
$LoginRS__query = sprintf("SELECT username FROM member WHERE username=%s", GetSQLValueString($loginUsername, "text"));
mysql_select_db($database_memberconn, $memberconn);
$LoginRS=mysql_query($LoginRS__query, $memberconn) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);

//if there is a row in the database, the username was found - can not add the requested username
if($loginFoundUser){
$MM_qsChar = "?";
//append the username to the redirect page
if (substr_count($MM_dupKeyRedirect,"?") >=1) $MM_qsChar = "&";
$MM_dupKeyRedirect = $MM_dupKeyRedirect . $MM_qsChar ."requsername=".$loginUsername;
header ("Location: $MM_dupKeyRedirect");
exit;
}
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$insertSQL = sprintf("INSERT INTO member (username, password, question, answer, truename, sex, address, tel, QQ, email, authority) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)",
GetSQLValueString($_POST['username'], "text"),
GetSQLValueString($_POST['password'], "text"),
GetSQLValueString($_POST['question'], "text"),
GetSQLValueString($_POST['answer'], "text"),
GetSQLValueString($_POST['truename'], "text"),
GetSQLValueString($_POST['sex'], "text"),
GetSQLValueString($_POST['address'], "text"),
GetSQLValueString($_POST['tel'], "text"),
GetSQLValueString($_POST['QQ'], "text"),
GetSQLValueString($_POST['email'], "text"),
GetSQLValueString($_POST['authority'], "text"));

mysql_select_db($database_memberconn, $memberconn);
$Result1 = mysql_query($insertSQL, $memberconn) or die(mysql_error());

$insertGoTo = "regok.php";
if (isset($_SERVER['QUERY_STRING'])) {
$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
$insertGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $insertGoTo));
}
?>

}
这是代码，点击注册网页提示问题出在这一句header(sprintf("Location: %s", $insertGoTo));

header('Location:要跳转的链接');
