Question

当我单击“提交”按钮时，我没有遇到任何问题，并且我的数据没有插入数据库中。

我正在尝试创建一个注册页面（register2.html）和db_reg.php以将数据发送到数据库中。

但是我发现Html页面甚至没有读取PHP页面。

db_reg.php

<?php
session_start();

// connect to the database
$db = mysqli_connect('localhost', 'root', '', 'mdff');

// initializing variables
$fullName = $_POST['fullName'];
$email    = $_POST['email'];
$phoneNum = $_POST['phoneNum'];
$password1 = $_POST['password1'];
$password2 = $_POST['password2'];
$errors = array(); 


// REGISTER USER
if (isset($_POST['register2'])) {
  // receive all input values from the form
  $fullName = mysqli_real_escape_string($db, $_POST['fullName']);
  $email = mysqli_real_escape_string($db, $_POST['email']);
  $phoneNum = mysqli_real_escape_string($db, $_POST['phoneNum']);
  $password1 = mysqli_real_escape_string($db, $_POST['password1']);
  $password2 = mysqli_real_escape_string($db, $_POST['password2']);

  // form validation: ensure that the form is correctly filled ...
  // by adding (array_push()) corresponding error unto $errors array
  if (empty($fullName)) { array_push($errors, "Full Name is required"); }
  if (empty($email)) { array_push($errors, "Email is required"); }
  if (empty($phoneNum)) { array_push($errors, "Phone Number is required"); }
  if (empty($password1)) { array_push($errors, "Password is required"); }
  if (empty($password2)) { array_push($errors, "Password repeat is required"); }
  if ($password1 != $password2) {
    array_push($errors, "The two passwords do not match");
  }

  // first check the database to make sure 
  // a user does not already exist with the same username and/or email
  $user_check_query = "SELECT * FROM admin WHERE fullname='$fullName' OR email='$email' LIMIT 1";
  $result = mysqli_query($db, $user_check_query);
  $user = mysqli_fetch_assoc($result);

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

    if ($user['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);//encrypt the password before saving in the database

    $query = "INSERT INTO admin (fullName, email, phoneNum, password1, password2) 
              VALUES('$fullName', '$email', '$phoneNum', '$password1', 'password2')";
    mysqli_query($db, $query);
    $_SESSION['fullName'] = $fullName;
    $_SESSION['success'] = "You are now registered";
    header('location: index.php');
  }
}

Answer 1

您应该将操作添加到表单中，而不是将操作添加到div中：

<form action="db_reg.php" method="post">

Answer 2

您的PHP脚本正在等待$_POST["register2"]，该脚本永远不会到达。

在这里->确保您的提交按钮具有name="register2"属性，或者您可以在html <input type="hidden" name="register2"内的某个地方添加form

<div class="submit-btn-area">
    <a href="#" class="btn btn-primary btn-md" role="button">Submit</a> 
</div>

我不使用引导程序，但是我想上面的标记将变成一个提交按钮，如果是这种情况，您可以向其中添加name="register 2"属性如下

<div class="submit-btn-area">
    <a href="#" class="btn btn-primary btn-md" role="button" name="register2">Submit</a> 
</div>

EDIT 在PHP脚本的顶部，您可以通过调用$_POST来检查var_dump($_POST)变量中包含的内容，并查看表单数据是否存在。

如果不存在，则可能需要按如下所示将上面的标记更改为“提交”按钮

<div class="submit-btn-area">
    <input type="submit" name="register2" value="Submit" class="btn btn-primary btn-md" role="button"> 
</div>

Answer 3

使用

<div class="submit-btn-area">

<input type="submit" name="register2">

</div>
