Question

第一次提问者！

我正在制作一份注册表格，并且我已将其全部提交到我的数据库中，但我希望它在用户错过某些详细信息或已经注册了电子邮件地址等时向页面报告。

目前，我可以不断提取相同的数据，并想知道如何解决这个问题。

我的表单目前发布到另一个php文件，因此从中获取反馈令我感到困惑。

目前，如果用户注册这种情况发生在join.php（他们从html表单加入）：

$join = $_GET['success'];
if($join=='yes')
{
echo "Well done!";
}
?>

因为在signup.php（查询所在的位置），如果已注册，则设置此项。

header('Location: join.php?success=yes');

这是非常基本的......
