"Submit" 我的注册表单中的按钮 returns 没有

Question

我已经用 php 建立了一个注册系统，它应该通过我工作的 apache 和 mysql 服务器与 phpmyadmin 连接。但是当我点击 "signup" 旋钮时，而不是打开 up/running signup.inc.php，它看起来像这样：

下面分别是：dbh.inc.php、signup.inc.php、index.met.interne.header.en.footer（主文件）、signup.inc.php。很抱歉 ULing 了这么多文件。

<?php

$dbServername = "localhost";
$dbUsername = "root";
$dbPassword = "";
$dbName = "login.system";

$conn = mysql_connect($dbServername, $dbUsername, $dbPassword, $dbName);

<?php

if (isset($_POST['submit'])) {

 include_once 'dbh.inc.php';

 $uid = mysql_real_escape_string($conn, $_POST['uid']);
 $kvk = mysql_real_escape_string($conn, $_POST['kvk']);
 $bedrijfsnaam = mysqli_real_escape_string($conn, $_POST['bedrijfsnaam']);
 $merknaam = mysql_real_escape_string($conn, $_POST['merknaam']);
 $email = mysql_real_escape_string($conn, $_POST['email']);
 $wachtwoord = mysql_real_escape_string($conn, $_POST['wachtwoord']);

 //Error handlers
 //Check for empty fields
 if (empty($kvk) && empty($bedrijfsnaam) ) {
  header("Location: ../signup.php?signup=empty");
 exit();
 } else {
 //Check if input characters are valid
  if (!preg_match("/^[0-9]*$/", $kvk)) || (!preg_match("/^[a-zA-Z]*$/", $bedrijfsnaam)) {
   header("Location: ../signup.php?signup=invalid");
  } else {
   //Check if email is valid
   if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
    header("Location: ../signup.php?signup=invalid.email");
    exit();
   }
     else {
     //Hashing the password
     $hashedPwd = password_hash($pwd, PASSWORD_DEFAULT);
     //Insert the user into the database [deze moeten we nog af chappen zodat alles khlopt]
     $sql = "INSERT INTO users (buser_kvk, buser_kvk, buser_bedrijfsnaam, buser_merknaam, buser_email, buser_wachtwoord) VALUES 
     ('$bedrijfsnaam', '$merknaam', '$email', '$kvk', '$uid', '$hashedPwd');";
     mysql_query($conn, $sql);
     header("Location: ../signup.php?signup=success");
     exit();
    }
    
   }
 }


} else {
 header("Location: ../signup.php");
 exit();
}

n "signup.inc.php" 但这是它的样子：

经过进一步调查，我们发现服务器配置有点不对劲，我们不得不进行一些更改。重定向未使用 HTTP 协议，也未在打开时执行文件。

一旦我们弄明白了，就没有建立与数据库的连接，因此 mysqli_real_escape_string() 返回空值。为了解决这个问题，我们确保 mysqli_connect() 中的所有信息都是正确的，但事实并非如此。更不用说所有文件中参数的顺序都是错误的（mysql/mysqli 差异）。

最后，由于一些奇怪的原因，users table 在数据库中找不到，所以我们不得不创建它并修复 SQL 查询，因为数据未插入。

其余的是一些逻辑错误之类的东西，但是这里没有清晰的方法来解释所有这些。问题已成功解决。

TL;DR

数据发送正确，但一些服务器配置错误和编程错误导致了所描述的所有问题（以及其他一些问题）。
