这是连接数据库的代码。我认为问题出在这部分，但我找不到原因。我的数据库已经符合此代码中的详细信息
$con=mysqli_connect("localhost","root","","hotel");

email = '$_POST[email]'";
$rs = mysqli_query($con,$check);
$data = mysqli_fetch_array($rs, MYSQLI_NUM);

alert('User Already in Exists')</script>";

请帮帮我。每次按提交按钮时，都会弹出“在数据库中添加用户时出错”的提示
答案 0 :(得分：-1)
首先使用准备好的语句。如果您不了解它们，请阅读它们。
现在您可以执行以下操作：
POST变量以数组形式存储，因此应该以访问数组的方式对其进行访问。
您的$_POST['variable']不太正确
POST变量应类似于$_POST['username']，而不应类似于$_POST[username]
通过mysqli_real_escape_string函数传递post变量后最好保存它们：
例如：$username = mysqli_real_escape_string($_POST['username']);
然后在查询中使用此$username。
