注册表单php只刷新phpMyAdmin

问题描述 投票：0回答：2

我创建了一个registration.php登录user.php一个error.php和一个server.php，其中的错误验证和服务器将我的php表单连接到数据库。 login.php工作正在说错误的ID和/或密码，而注册表不起作用。当我点击提交它就像刷新一样，没有保存到数据库。尝试3天，无法理解为什么。也许是我的p.c问题？我正在使用XAMPP和phpmyadmin以及dreamweaver。

这是我的register.php。

<?php include('server.php') ?>
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Registration Form</title>
<link rel="stylesheet" type="text/css" href="forms.css">
</head>
<body>
<div class="header">
    <h2>Register</h2>
</div>

<form method="post" action="register.php">
    <?php include('errors.php'); ?>
    <div class="input-group">
        <label>Name:</label>
        <input type="text" name="name">
    </div>
    <div class="input-group">
        <label>Surname:</label>
        <input type="text" name="surname">
    </div>
    <div class="input-group">
        <label>Password:</label>
        <input type="password" name="password_1">
    </div>
    <div class="input-group">
        <label>Confirm Paswword:</label>
        <input type="password" name="password_2">
    </div>
    <div class="input-group">
        <label>Student ID:</label>
        <input type="text" name="studentid">
    </div>
    <div class="input-group">
        <label>Email:</label>
        <input type="text" name="email">
    </div>
    <div class="input-group">
        <label>Course:</label>
        <input type="text" name="course">
    </div>  
    <div class="input-group">
        <center><button type="submit" name="register" class="btn">Register</button></center>
    </div>
    <p>
        Already a registered student? <a href="login.php">Sign in</a>
    </p>
</form>
</body>
</html>

这是我的server.php

<?php

    session_start();

    // variable declaration
    $name = "";
    $surname = "";
    $email = "";
    $studentid = "";
    $password_1 ="";

    $course = "";
    $errors = array();
    $_SESSION['success'] = "";

    // connect to database
    $db = mysqli_connect('localhost', 'root', '', 'registration');

    // if register button clicked receive all inputs from the form
    if (isset($_POST['reg_user'])) {
    $name = mysqli_real_escape_string($db, $_POST['name']);
    $surname = mysqli_real_escape_string($db, $_POST['surname']);
    $email = mysqli_real_escape_string($db, $_POST['email']);

    $password_1 = md5($password_1);
    $password_2 = mysqli_real_escape_string($db, $_POST['password_2']);
    $password_2 = md5($password_2);
    $course = mysqli_real_escape_string($db, $_POST['course']);


    // ensure that form fields are filled properly
    if (empty($name)) { 
        array_push($errors, "Name is required"); 
                      }
    if (empty($surname)) { 
        array_push($errors, "Surame is required"); 
    }
    if (empty($email)) { 
        array_push($errors, "Email is required"); 
    }
    if (empty($studentid)) { 
        array_push($errors, "Student ID is required"); 
    }
    if (empty($password_1)) { 
        array_push($errors, "Password is required"); 
    }
    if (empty($course)) { 
        array_push($errors, "Course is required"); 
    }

    if ($password_1 != $password_2) {
    array_push($errors, "The two passwords do not match");
    }   

    if (count($errors) == 0) {
    $password = md5($password_1); //encrypt the password before saving in the database
    $query = "INSERT INTO users (id, name, surname, email, studentid, password, course) 
              VALUES(0,'$name','$surname', '$email', '$studentid' '$password', '$course')";
    mysqli_query($db, $query);
    $_SESSION['studentid'] = $studentid;
    $_SESSION['success'] = "You are now logged in";
    header('location: index.php');
  }

}

// login user
if (isset($_POST['login_user'])) {
  $studentid = mysqli_real_escape_string($db, $_POST['studentid']);
  $password = mysqli_real_escape_string($db, $_POST['password']);

  if (empty($studentid)) {
    array_push($errors, "Student ID is required");
  }
  if (empty($password)) {
    array_push($errors, "Password is required");
  }

  if (count($errors) == 0) {
    $password = md5($password);
    $query = "SELECT * FROM users WHERE studentid='$studentid' AND password='$password'";
    $results = mysqli_query($db, $query);

      $_SESSION['studentid'] = $studentid;
      $_SESSION['success'] = "You are now logged in";
      header('location: index.php');
    }else {
        array_push($errors, "Wrong Student ID or Password. Please try again.");
    }
  }
}

?>

你的按钮名称与php中的名称不同

//previous code button clicked for register
if (isset($_POST['reg_user'])) {}

代替

//button clicked for register
if (isset($_POST['register'])) {}

还有你的查询如果你的“id”是一个自动增量，把它留空而不是0，你也可以这样做

$query = "INSERT INTO users (name, surname, email, studentid, password, 
course)VALUES('$name','$surname', '$email', '$studentid' '$password', '$course')";

更新以帮助任何类似问题的人

对于可能有类似代码挑战的任何人，请检查每个半列，逗号和点是否应该是它们的位置。

您也可以通过回显值来调试，以了解问题可能来自何处。

同时阅读评论，你可以从那里获得你需要的东西。希望这有帮助。

问题在你的查询中你采取surname而不是username。从此更改查询

$query = "INSERT INTO users (name, surname, email, studentid, password, course) 
              VALUES(0,'$name','$surname', '$email', '$studentid' '$password', '$course')";

对此

$query = "INSERT INTO users (id, name, surname, email, studentid, password, course) 
              VALUES('$name','$username', '$email', '$studentid' '$password', '$course')";

并且代码中存在大量拼写错误。请放松并检查所有拼写。
