我有在教程帮助下编写的验证码。代码对我来说看起来是正确的，表单上的提交按钮使用“POST”方法链接到正确的页面。但是，在提交注册信息时，浏览器会打开一个后端页面，显示脚本的某些部分。显然，这并不是要这样做，而是访问所述页面以进行验证并链接回注册页面，并在 url 中嵌入一条成功消息。
这是包含表单的 signup.php 页面:
<!DOCTYPE html>
<html>
<head>
<title>Signup</title>
<link rel="stylesheet" type="text/css" href="signupstyle.css">
</head>
<body>
<div class="signup-wrapper">
<h3>Sign Up</h3>
<form class="signup-form" action="functions/signup.func.php" method="POST">
<ul>
<li>
<input type="text" name="fname" placeholder="First Name">
</li>
<li>
<input type="text" name="lname" placeholder="Last Name">
</li>
<li>
<input type="text" name="username" placeholder="Username">
</li>
<li>
<input type="email" name="email" placeholder="Email">
</li>
<li>
<input type="password" name="password" placeholder="Password">
</li>
<li>
<button>Sign Up</button>
</li>
</ul>
</form>
</div>
<footer>
</footer>
</body>
</html>
它要发布到的页面是后端，这是它的代码:
<? php
if (isset($POST['submit'])) { //ensure that the submit button was pressed to
access the page.
include_once 'dbc.func.php';
$fname = mysqli_real_escape_string($conn, $_POST['fname']);
$lname = mysqli_real_escape_string($conn, $_POST['lname']);
$username = mysqli_real_escape_string($conn, $_POST['username']);
$email = mysqli_real_escape_string($conn, $_POST['email']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
//HANDLING ERRORS
//Checking for empty fields
if (empty($fname) || empty($lname) || empty($username) || empty($email) || ($password)) {
header("Location: .../signup.php?signupfields=empty"); //if any of the above are empty, redirect to signup page.
exit();
}else{
//Checking for invalid input characters
if (!preg_match("/^[a-zA-Z]*$/", $fname) || (!preg_match("/^[a-zA-Z]*$/", $lname)) {
header("Location: .../signup.php?signupfields=invalidchars"); //if any of the above are empty, redirect to signup page.
exit();
}else{
//Checking the email validity
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
header("Location: .../signup.php?signupfields=invalidemail"); //if any of the above are empty, redirect to signup page.
exit();
}else{
//Checking for username similarity
$sql = "SELECT * FROM users WHERE username = '$username'";
$resulter = mysqli_query($conn, $sql);
$checkResulter = mysqli_num_rows($resulter);
if ($checkResulter > 0) {
header("Location: .../signup.php?signupfields=usernametaken"); //if any of the above are empty, redirect to signup page.
exit();
}else{
//Hashing the inputted password
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);
//Inserting the inputted user details into the database
$inputer = "INSERT INTO users (fname, lname, username, email, password) VALUES ('$fname', '$lname', '$username', '$email', '$hashedPassword');";
mysqli_query($conn,$inputer);
header("Location: .../signup.php?signupsuccess"); //redirect to signup page.
exit();
}
}
}
}
}else{
header("Location: ../signup.php?badlogin"); //redirect users to the
signup.php page.
exit();
}
看起来一切正常，但它会抛出 signup.func.php 页面，页面上显示以下代码:
0) { header("Location: .../signup.php?signupfields=usernametaken"); //if any of the above are empty, redirect to signup page. exit(); }else{ //Hashing the inputted password $hashedPassword = password_hash($password, PASSWORD_DEFAULT); //Inserting the inputted user details into the database $inputer = "INSERT INTO users (fname, lname, username, email, password) VALUES ('$fname', '$lname', '$username', '$email', '$hashedPassword');"; mysqli_query($conn,$inputer); header("Location: .../signup.php?signupsuccess"); //redirect to signup page. exit(); } } } } }else{ header("Location: ../signup.php?badlogin"); //redirect users to the signup.php page. exit(); }
不出所料，这并不意味着这样做，我已经厌倦了在代码中没有发现任何错误。谁能帮我吗？
编辑:
阅读提供的文章后，我使用了错误处理程序
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
当我再次运行代码时，它给了我这个:
Warning: mysqli_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\xampp\htdocs\Rizeapp\functions\dbc.func.php on line 10
fatal error :未捕获 mysqli_sql_exception:php_network_getaddresses:getaddrinfo 失败:不知道这样的主机。在 C:\xampp\htdocs\Rizeapp\functions\dbc.func.php:10 堆栈跟踪:#0 C:\xampp\htdocs\Rizeapp\functions\dbc.func.php(10): mysqli_connect('localhost, root ...') #1 C:\xampp\htdocs\Rizeapp\functions\signup.func.php(4): include_once('C:\xampp\htdocs...') #2 {main} 抛出在 C:\xampp\htdocs\Rizeapp\functions\dbc.func.php 第 10 行
如果这是我认为的意思，那就是 XAMPP 服务器详细信息不正确。我会研究解决这个问题，看看代码是否会运行。
编辑 2:当它起作用时，我真的很高兴。上面 EDIT 1 中抛出的第二个错误是由于我所知道的最愚蠢的错误:我这样做了:
$conn = mysqli_connect("$dbServername, $dbUsername, $dbPassword,
$dbName");
取而代之的是:
$conn = mysqli_connect("$dbServername", "$dbUsername", "$dbPassword",
"$dbName");
感谢大家的迅速回复，最终解决了问题。现在，我可以继续全力推进该项目。干杯。
最佳答案
发现的问题:
- 第一行代码错误:
<? php. php 文件然后像文本文件一样显示代码。正确:<?php. - 第二个之前
!preg_match...在if语句是一个错误的字符(.正确:将被删除。 - 在 php 代码中，当编写注释行时不以
//开头, 或外面/* ... */, 发生错误。 - 错误:
$POST['submit']. HTTP POST 方法的正确全局变量名为$_POST.所以，正确的代码是:$_POST['submit']. - 如果你定义
<button>Sign Up</button>，那么你必须给它一个名字(比如<button name="submit">Sign Up</button>)，以便能够用if (isset($_POST['submit'])) {...}来引用它。 . - 错误:
.../abc/xyz.php.正确:../abc/xyz.php. - 错误:
if (... || empty($email) || ($password)) {...}.正确:if (... || empty($email) || empty($password)) {...}.
建议:
- 将php处理代码放在
signup.php中, 而不是signup.func.php并相应地改变它。表单的 action 属性将为signup.php, 或""对于 HTML5，那么。这样您就可以直接(例如现场)向用户显示任何消息，并且在注册处理成功时最后只执行一次重定向(例如到login.php页面)。 - 申请好error reporting系统，以便查看并相应地处理 php 引擎可能抛出的错误和异常。专门针对 mysqli:here .对于 PDO here .
- 开始使用所谓的 prepared statements ，为了防止SQL injection .阅读this小而有效的文章。
- 开始使用面向对象的 mysqli 扩展而不是过程式扩展——每个 mysqli 函数都有以两种形式呈现的 php.net 文档。更好的是:开始使用 PDO extension而不是 mysqli。这里(同上)tutorial .
promise 的替代代码(使用面向对象的 mysqli)
它包括我上面的建议。按原样运行它以对其进行测试。但是首先更改表结构(参见下面的标题使用的表结构)，更改connection.php中的数据库凭据(参见标题includes/connection.php 下面)并按照下面代码部分的标题建议创建一个文件系统结构。
要从生产环境(当错误未显示在屏幕上时)切换到开发环境(当所有引发的错误都显示在屏幕上时)，只需更改常量 APP_ENV 的值(在 handlers.php 中)从 'prod' 到 'dev' 并返回(参见标题 includes/handlers.php)。然后，为了测试它，将表名“users”重命名为另一个错误的名称，例如。或者将两条sql语句的第一条设置为NULL : $sql = NULL; .

使用的表结构
由于您使用的是正确的哈希函数 ( password_hash )，所以 password列的长度至少为 255 个字符。
CREATE TABLE `users` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`first_name` varchar(100) DEFAULT NULL,
`last_name` varchar(100) DEFAULT NULL,
`email` varchar(100) DEFAULT NULL,
`username` varchar(100) DEFAULT NULL,
`password` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
