Question

我是网络开发的新手，想要制作一个简单的登录表单，虽然不知道为什么我的登录按钮没有响应，但用户需要输入他们的电子邮件密码。一旦用户输入密码，登录按钮就不起作用。

 <?php
 session_start();



    if(isset($_POST['submit'])) {
        include_once("php/config/database.php"); 
        $Email = strip_tags($_POST['Email']);
        $dbPassword = strip_tags($_POST['Password']);

        $Email = stripslashes($Email);
        $dbPassword = stripslashes($dbPassword);

        $Email = mysqli_real_escape_string($conn, $Email);
        $dbPassword = mysqli_real_escape_string($conn, $dbPassword);

        $dbPassword = md5($dbPassword);

        $sql = ("SELECT * FROM 'Users' WHERE Email='$Email' LIMIT 1");
        $query = mysqli_query($conn, $sql);
        $row = mysqli_fetch_array($query);
        $UserID = $row['UserID'];
        $dbpass_Password = $row['Password'];

        if($dbPassword == $dbpass_Password) {
            $_SESSION['Email'] = $Email;
            $_SESSION['UserID'] = $UserID;
            header("Location: account.php");
        } 
        else 
        {
            echo "You didn't enter the correct details!";
        }

    } 


?>

Answer 1

你的HTML坏了：

      <form  action="index.php" method="POST" />  
                                              ^---

您自动关闭了表单标记，因此您网页上的每个输入字段都是表单的 OUTSIDE 。

另外请注意，您还有其他逻辑错误：

        if($Password == $dbpass_Password) {
              ^----

$password是用户PW的sql-escaped版本。如果该密码自然包含SQL元字符，则密码将不会与数据库中的密码相等。在DB插入过程中会剥离这些转义，并且您最终会执行类似

的操作

 "Miles O\'Brien" == "Miles O'Brien"

并返回错误的不匹配。

登录按钮不起作用
