Question

我已经使用php构建了一个注册系统，它应该通过我的工作apache和mysql服务器与phpmyadmin连接。但是，当我点击“注册”旋钮，而不是打开/运行signup.inc.php时，它看起来像这样：

enter image description here

下面分别是：dbh.inc.php，signup.inc.php，index.met.interne.header.en.footer（主文件）和signup.inc.php。很抱歉没有这么多文件。

<?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”但这就是它的样子：

经过进一步调查，我们发现服务器配置有点偏，我们不得不做一些改动。重定向不使用HTTP协议，也不在打开时执行文件。

一旦弄清楚了，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表在数据库中找不到，所以我们必须创建它并修复SQL查询，因为没有插入数据。

其余的是一些逻辑错误和类似的东西，但没有干净的方法来解释这一切。问题得到了成功解决。

数据正在正确发送，但是一些服务器配置错误和编程错误导致了所有描述的问题（还有一些问题）。

我的注册表单中的“提交”按钮不返回任何内容
