Php 无法将数据插入数据库

我正在使用PHP创建一个注册和登录页面。我已经在注册页面上编写了代码，但由于某些原因，我试图在注册页面中插入的数据没有添加到数据库中。它不会显示任何错误，也不会重定向到其他页面

我已经查阅了很多与这个项目相关的视频和代码，但没有一个有效

<?php

session_start();

$username = "";
$email    = "";
$errors   = [];

$db = mysqli_connect('localhost', 'root', '', 'joblister');

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


    $username   = mysqli_real_escape_string($db, $_POST['username']);
    $email      = mysqli_real_escape_string($db, $_POST['email']);
    $password_1 = mysqli_real_escape_string($db, $_POST['password_1']);
    $password_2 = mysqli_real_escape_string($db, $_POST['password_2']);

    if (empty($username)) {
        array_push($errors, "Username is required");
    }
    if (empty($email)) {
        array_push($errors, "Email is required");
    }
    if (empty($password_1)) {
        array_push($errors, "Password is required");
    }
    if ($password_1 != $password_2) {
        array_push($errors, "The two passwords do not match");
    }

    // a user does not already exist with the same username and/or email
    $jobseeker_check_query = "SELECT * FROM jobseeker WHERE username='$username' OR email='$email' LIMIT 1";
    $result                = mysqli_query($db, $jobseeker_check_query);
    $jobseeker             = mysqli_fetch_assoc($result);

    if ($jobseeker) { // if user exists
        if ($jobseeker['username'] === $username) {
            array_push($errors, "Username already exists");
        }

        if ($jobseeker['email'] === $email) {
            array_push($errors, "email already exists");
        }
    }

    // Finally, register user if there are no errors in the form
    if (count($errors) == 0) {
        $password = md5($password_1);

        $query = "INSERT INTO jobseeker (firstname, lastname, gender, email, username password, address, contact,dob)
              VALUES('$firstname','$lastname','$gender','$email','username','$password', '$address','$contact','dob')";
        mysqli_query($db, $query);
        $_SESSION['username'] = $username;
        $_SESSION['success']  = "You are now logged in";
        header('location: FirstPage.php');
    }
}

没有显示任何错误消息。唯一的问题是数据没有添加到数据库中

// Finally, register user if there are no errors in the form
if (count($errors) == 0) {
  $password = md5($password_1);

  $query = "INSERT INTO jobseeker (firstname, lastname, gender, email, **username password**, address, contact,dob)
    VALUES('$firstname','$lastname','$gender','$email','username','$password', '$address','$contact','dob')";

    // ... rest of the code
}

我认为您需要在用户名和密码之间加一个逗号。

您对SQL注入开放，应该立即寻址$password=md5$password\u 1；这不是存储密码的安全方法。考虑使用注射问题。获取更多信息。电子邮件、用户名密码、地址中缺少逗号。启用正确的错误报告，您将看到它！添加mysqli_REPORT mysqli_REPORT_ERROR | mysqli_REPORT_STRICT；在代码的顶部，您将看到所有MySQL错误都是PHP异常。
