PHP 表单到数据库 - 不工作

Question

再一次，我有一个要提交到我的数据库的表单，但它不起作用，我真的不知道为什么。我测试了所有内容，但在我的代码中看不到任何错误。

这是我的表单代码:

<!-- Begin # Registration Form -->
<form method="post" action="register_teacher.php" id="registration-teacher-form" class="form-horizontal">
<div class="col-sm-12">
    <p>Willkommen zu unserer <strong>Online - Essensreservierung</strong> für Lehrer. Bitte geben Sie im nachfolgenden Schritt Ihre Daten bekannt. Die Wahl des Menüs, sowie die Essenstage, können Sie im nächsten Schritt angeben.</p><br>

        </div>
    </div>
    </form>
<!-- End # Registration Form -->

这是我的 register_teacher.php 的代码:

    <?php
    // Create connection credentials
    $db_host = 'localhost';
    $db_name = 'DBNAME';
    $db_user = 'DBUSER';
    $db_pass = 'DBPASS';

// Create mysqli object
$connection = new mysqli ($db_host, $db_user, $db_pass, $db_name);

// Error Handler
if ($connection->connect_error) {
    printf ("Connection failed: %s\n", $connection->connect_error);
    exit();
}   
?>

<?php


// Check if form is submitted
if (isset ($_POST['submit1'])) {
    $schul = mysqli_real_escape_string ($connection, $_POST['schul']);
    $emai = mysqli_real_escape_string ($connection, $_POST['emai']);
    $passwor = mysqli_real_escape_string ($connection, $_POST['passwor']);
    $anred = mysqli_real_escape_string ($connection, $_POST['anred']);
    $vornam = mysqli_real_escape_string ($connection, $_POST['vornam']);
    $nachnam = mysqli_real_escape_string ($connection, $_POST['nachnam']);
    $strass = mysqli_real_escape_string ($connection, $_POST['strass']);
    $pl = mysqli_real_escape_string ($connection, $_POST['pl']);
    $or = mysqli_real_escape_string ($connection, $_POST['or']);
    $telefo = mysqli_real_escape_string ($connection, $_POST['telefo']);




    // Validate Input

$sql="INSERT INTO `teacher` (`schule`, `email`, `password`, `anrede`, `firstname`, `lastname`, `street`, `plz`, `city`, `phonenumber`)
VALUES ('$schul', '$emai', '$passwor' '$anred', '$vornam', '$nachnam', '$strass', '$pl', '$or', '$telefo')";



$query1 = mysqli_query($connection, $sql );
if(!mysqli_query($connection, $query1) ) {
    exit( header("Location: /teachercp/index.php") );
}


}
?>

MySQL 连接正常。我也没有收到任何错误消息。每次单击“注册”时，我都会转到 register_teacher.php 上的空白页面!无法重定向到 teachercp/index.php，我的数据库中没有数据。

有什么建议吗？

谢谢，克里斯

我在本地服务器上测试了你的代码。它显示此错误:

Warning: mysqli_error() expects exactly 1 parameter, 0 given in D:\xampp\htdocs\111\register_teacher.php on line 39

我在你的代码中得到的错误是:

您在第 39 行漏掉了一个逗号。在您漏掉的地方查看我的图片。
