Question

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

database

Answer 1

问题出在您的查询中您可以使用surname代替username。更改查询从这个

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

到此

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

代码中有很多拼写错误。请放松并检查所有拼写。

Answer 2

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'])) {}

而不是

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

以及您的查询如果你的“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')";
