请尝试将验证代码保留在registerinsert.php中，并将表单操作设置为registerinsert.php编辑表单标记，如下所示
<form role="form" name="frm" action="registerinsert.php" method="post">
if (!mysqli_query($sql))
{
die('Error:' . mysql_error());
}
您混合了mysql_*和mysqli_*函数。您没有将数据发送到registerinsert.php。我建议将registerinsert.php中的代码添加到register.php页面。它应该很好用。另外，如前所述，您的数据库正在混合mysql和mysqli。。。我建议只使用mysqli。
