我单击提交按钮时出现问题，没有任何反应，并且我的数据未插入数据库中。
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');
}
}

最佳答案
您的PHP脚本正在等待$_POST["register2"]，它永远不会到达。
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，可以按如下所示向其添加
name="register 2"属性<div class="submit-btn-area">
<a href="#" class="btn btn-primary btn-md" role="button" name="register2">Submit</a>
</div>
编辑
在PHP脚本的顶部，可以通过调用
$_POST来检查var_dump($_POST)变量包含的内容，并查看是否存在表单数据。如果不存在，则可能需要将上面的标记更改为“提交”按钮，如下所示
<div class="submit-btn-area">
<input type="submit" name="register2" value="Submit" class="btn btn-primary btn-md" role="button">
</div>
