问题描述

我有我在教程的帮助下编写的验证码.该代码对我来说看起来是正确的,并且表单上的提交"按钮使用"POST"方法链接到了右页.但是,在提交注册信息时,浏览器将打开一个后端页面,显示脚本的某些部分.显然,这并非意味着要这样做,而是要访问该页面进行验证,并链接回注册页面,并在URL中嵌入成功消息.

I have verification code I wrote with help from a tutorial. The code looks correct to me, and the submit button on the form links to the right page, using the 'POST' method. However, on submitting the signup info, the browser opens a backend page, displaying some parts of the script. Obviously, it's not meant to do that, rather, it's to access the said page for verification and link back to the signup page with a success message embedded in the url.

这是signup.php页面,其中包含以下格式:

Here is the signup.php page that contains the form:

<!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> 

要发布到的页面是后端,这是该页面的代码:

The page it is to post to is backend and here is the code for that:

<? 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();
} 

似乎一切都井井有条,但它会抛出signup.func.php页面,并在页面上显示以下代码:

It would seem everything is in order, but it throws the signup.func.php page with the following code displaying on the page:

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(); } 

不足为奇的是,这并不意味着要这样做,而且我对在代码中没有发现错误感到厌倦.谁能帮我吗?

Unsurprisingly, it's not meant to do that, and I'm fatigued with finding no errors in the code. Can anyone help me out?

阅读提供的文章后,我使用了错误处理程序

After reading the articles provided, I used the error handler

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); 

当我再次运行代码时,它给了我:

And it gave me this when I ran the code again:

警告:mysqli_connect():php_network_getaddresses:getaddrinfo失败:此类主机未知.在第10行的C:\ xampp \ htdocs \ Rizeapp \ functions \ dbc.func.php中

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

致命错误:mysqli_sql_exception未捕获:php_network_getaddresses:getaddrinfo失败:此类主机未知.在C:\ xampp \ htdocs \ Rizeapp \ functions \ dbc.func.php:10中堆栈跟踪:#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C:第10行上的\ xampp \ htdocs \ Rizeapp \ functions \ dbc.func.php

如果这就是我的意思,那就是XAMPP服务器详细信息不正确.我将研究解决该问题,并查看代码是否将运行.

If this is what I think it means, it's that the XAMPP server details are incorrect. I'll look into fixing that and see if the code will run.

当它起作用时,我真的高兴地大喊.上面的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:

EDIT 2: I literally shouted in joy when it worked. The second error thrown in EDIT 1 above was due to the most silly mistake known to me: I did this:

$conn = mysqli_connect("$dbServername, $dbUsername, $dbPassword, 
$dbName"); 

代替此:

$conn = mysqli_connect("$dbServername", "$dbUsername", "$dbPassword", 
"$dbName"); 

感谢大家的迅速答复,最终解决了该问题.现在,我可以继续进行该项目.干杯.

Thank you all for your swift replies that ultimately fixed the problem. Now, I can continue with the project full steam ahead. Cheers.

错误页面

推荐答案

发现的问题:

  • 第一行代码错误:<? php. php文件会像文本文件一样显示代码.正确:<?php.
  • if语句中的第二个!preg_match...之前是错误的字符(.正确:将被删除.
  • 在php代码中,当编写注释行而不以//开头或在/* ... */之外时,会发生错误.
  • 错误:$POST['submit']. HTTP POST方法的正确全局变量名为$_POST.因此,正确的代码是:$_POST['submit'].
  • 如果定义了<button>Sign Up</button>,则必须给它起一个名字(如<button name="submit">Sign Up</button>),以便能够使用if (isset($_POST['submit'])) {...}对其进行引用.
  • 错误:.../abc/xyz.php.正确:../abc/xyz.php.
  • 错误:if (... || empty($email) || ($password)) {...}.正确:if (... || empty($email) || empty($password)) {...}.
  • First code line is wrong: <? php. The php file presents then the code like a text file. Correct: <?php.
  • Before the second !preg_match... in the if statement is a wrong character (. Correct: to be removed.
  • In php code, when writing comment lines without starting with //, or outside /* ... */, an error occurres.
  • Wrong: $POST['submit']. The correct global variable for the HTTP POST method is named $_POST. So, the correct code is: $_POST['submit'].
  • If you define <button>Sign Up</button>, then you have to give it a name (like <button name="submit">Sign Up</button>) in order to be able to reference it by it with if (isset($_POST['submit'])) {...}.
  • Wrong: .../abc/xyz.php. Correct: ../abc/xyz.php.
  • Wrong: if (... || empty($email) || ($password)) {...}. Correct: if (... || empty($email) || empty($password)) {...}.

建议:

  • 将php处理代码放在signup.php中,而不是在signup.func.php中,并相应地进行更改.表单的 action 属性将为signup.php,对于 HTML5 则为"".这样,当注册处理成功(例如,到login.php页)时,您就可以直接(例如在现场)向用户显示任何消息,并且最终仅执行一次重定向.
  • 应用一个好的错误报告系统,以便查看并相应地处理那些PHP引擎可能会抛出.专门针对mysqli:此处.对于PDO 此处.
  • 开始使用所谓的准备的语句 ,以防止 SQL注入.阅读这篇小文章,但有效的文章.
  • 开始使用面向对象的mysqli扩展而不是过程扩展-每个mysqli函数都有两种形式的php.net文档.甚至更好:开始使用 PDO扩展代替mysqli.这里(与上面相同)教程.
  • Put the php processing code in signup.php, instead of in signup.func.php and change it correspondingly. The form's action attribute will be signup.php, or "" for HTML5, then. That way you are able to directly (e.g. on-site) display any message to the user and also to perform only a single redirect in the end, when the sign-up processing is successful (for example to a login.php page).
  • Apply a good error reporting system, in order to see and correspondingly handle the errors and exceptions that the php engine might throw. For mysqli specifically: here. For PDO here.
  • Start using the so called prepared statements, in order to prevent SQL injection. Read this little, but effective article.
  • Start using the object-oriented mysqli extension instead of the procedural one - each mysqli function have the php.net documentation presented in both forms. Even better: start using the PDO extension instead of mysqli. Here the (same as above) tutorial.

所承诺的替代代码(带有面向对象的mysqli)

它包括我上面的建议.按原样运行以对其进行测试.但是,请首先更改表结构(请参见下面的标题 Used表结构),并更改 connection.php 中的数据库凭据(请参见标题 includes/connection.php ),并按照下面的代码部分的标题建议创建文件系统结构.

It includes my above suggestions. Run it as it is to test it. But change the table structure first (see title Used table structure below), change the db credentials in connection.php (see title includes/connection.php below) and create a filesystem structure as suggested by the titles of the code parts below.

要从生产环境(当错误未显示在屏幕上)切换到开发环境(当所有提出的错误均显示在屏幕上)时,只需进行更改 APP_ENV (在 handlers.php 中)的值从'prod''dev'并返回(请参见标题 includes/handlers.php ).然后,要对其进行测试,例如,将表名"users"重命名为另一个错误的名称.或将两个sql语句中的第一个设置为NULL:$sql = NULL;.

To toggle from a production environment (when the errors are not shown on screen) to a development environment (when all raised errors are displayed on screen), just change the value of the constant APP_ENV (in handlers.php) from 'prod' to 'dev' and back (see title includes/handlers.php). And then, to test it, rename the table name "users" to another wrong name, for example. Or set the first of the two sql statements to NULL: $sql = NULL;.

使用的表格结构

由于您使用的是正确的哈希函数(password_hash),因此password列的长度至少应为255个字符.

Used table structure

Since you are using the proper hashing function (password_hash), let the password column's length be at least 255 characters long.

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;
