Question

我正在尝试创建一个注册页面，如果用户插入所需的详细信息，然后单击注册按钮，它应该在选定的表中插入详细信息并在数据库中创建一个新表格，我的html代码是：

  <form method="POST" action="signuplink.php" class="form-inline justify-content-center">
<div class="col-md-6 justify-content-center form-group">
    <label class="sr-only">first_name</label>
    <input type="text" name="first_name" class="form-control" placeholder="First Name">
  </div>
<div class="col-md-6 justify-content-center form-group">
    <label class="sr-only">last_name</label>
    <input type="text" name="last_name" class="form-control" placeholder="Last Name">
</div>
<div class="col-md-6 justify-content-center form-group">
    <label class="sr-only">phonenumber</label>
    <input type="text" name="phonenumber" class="form-control" placeholder="Contact Number">
</div>
<div class="col-md-6 justify-content-center form-group">
    <label class="sr-only">username</label>
    <input type="text" name="username" class="form-control" placeholder="Username">
</div>
<div class="col-md-6 justify-content-center form-group">
    <label class="sr-only">email </label>
    <input type="text" name="email" class="form-control" placeholder="username@domain.com">
</div>
<div class="col-md-6 justify-content-center form-group">
    <label class="sr-only">password </label>
    <input type="password" name="password" class="form-control" placeholder="select password">
</div>
<button type="submit" name="submit" class="btn btn-success ">Signup</button>
</form>

php代码如下所示我重定向表单，当用户成功填写表单时，自动帮助创建新表：

<?php

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

    include 'connection.php';
$x = mysqli_real_escape_string ($connect, $_POST['email']);
$firstname= mysqli_real_escape_string ($connect, $_POST['first_name']);
$lastname= mysqli_real_escape_string ($connect, $_POST['last_name']);
$username= mysqli_real_escape_string ($connect, $_POST['username']);
$phonenumber= mysqli_real_escape_string ($connect, $_POST['phonenumber']);
$y= mysqli_real_escape_string ($connect, $_POST['password']);

//Error handlers
//Check for empty fields
if (empty($x) || empty($firstname) || empty($lastname) || empty($username) || empty($phonenumber) || empty($y))
{
    header("Location: signup.php?signup=empty");
    exit();
}
    else
{
//Check if input characters are valid
if (!preg_match("/^[a-zA-Z]*$/", $firstname) || !preg_match("/^[a-zA-Z]*$/", $lastname))
{
    header("Location: signup.php?signup=invalid");
    exit();
}
else
{
//Check if email is valid
if (!filter_var($x, FILTER_VALIDATE_EMAIL))
{
header("Location: signup.php?signup=email");
exit();
}
else
{
$_SESSION['first_name']=$firstname;
$sql = "SELECT * FROM users WHERE username='$username' or email='$x'";
$result = mysqli_query($connect,$sql);
$resultCheck = mysqli_num_rows($result);

if ($resultCheck > 0) {
header("Location: signup.php?signup=usertaken");
exit();
} else {
//Hashing the password
$hashedPwd = password_hash($y, PASSWORD_DEFAULT);
//Insert the user into the database
}
$sql = "INSERT INTO users (ID, username, phonenumber, email,first_name, last_name, password) VALUES ('','$username', '$phonenumber','$x','$firstname','$lastname','$hashedPwd');";
mysqli_query($connect, $sql);
header("Location: signup.php?signup=successfully_logged_in");
exit();
}
if($connect->query($sql)===TRUE)
{
$sql = "CREATE TABLE $username (
ID int,
LastName varchar(255),
FirstName varchar(255),
Address varchar(255),
City varchar(255)
)";
if ($connect->query($sql) === TRUE) {
echo "Table MyGuests created successfully";
} else {
echo "Error creating table: " . $connect->error;
}
}
}
}
}


else {
header("Location: signup.php");
exit();
}
?>

@ Fred-ii-非常感谢兄弟相信我，我解决了它并且它的工作完全正常，因为我想要它;下面是工作的PHP -

<?php

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

    include 'connection.php';

$x          = mysqli_real_escape_string ($connect, $_POST['email']);
$firstname  = mysqli_real_escape_string ($connect, $_POST['first_name']);
$lastname   = mysqli_real_escape_string ($connect, $_POST['last_name']);
$username   = mysqli_real_escape_string ($connect, $_POST['username']);
$phonenumber= mysqli_real_escape_string ($connect, $_POST['phonenumber']);
$y          = mysqli_real_escape_string ($connect, $_POST['password']);

//Error handlers
//Check for empty fields
if (empty($x) || empty($firstname) || empty($lastname) || empty($username) || empty($phonenumber) || empty($y))
{
    header("Location: signup.php?signup=empty");
    exit();
}
    else
{
//Check if input characters are valid
if (!preg_match("/^[a-zA-Z]*$/", $firstname) || !preg_match("/^[a-zA-Z]*$/", $lastname))
{
    header("Location: signup.php?signup=invalid");
    exit();
}
else
{
//Check if email is valid
if (!filter_var($x, FILTER_VALIDATE_EMAIL))
{
header("Location: signup.php?signup=email");
exit();
}
else
{

$sql = "SELECT * FROM users WHERE username='$username' or email='$x'";
$result = mysqli_query($connect,$sql);
$resultCheck = mysqli_num_rows($result);

if ($resultCheck > 0) {
header("Location: signup.php?signup=usertaken");
exit();
} else {
//Hashing the password
$hashedPwd = password_hash($y, PASSWORD_DEFAULT);
//Insert the user into the database

$sql = "INSERT INTO users (ID, username, phonenumber, email, first_name, last_name, password) VALUES ('','$username', '$phonenumber','$x','$firstname','$lastname','$hashedPwd');";
mysqli_query($connect, $sql);
header("Location: signup.php?signup=successfully_logged_in");

if($connect->query($sql)===TRUE)
{
$sql = "CREATE TABLE $username (
ID int,
LastName varchar(255),
FirstName varchar(255),
Address varchar(255),
City varchar(255)
)";
if ($connect->query($sql) === TRUE) {
echo "Table MyGuests created successfully";
} else {
echo "Error creating table: " . $connect->error;
}
}
}
}
}
}
}


else {
header("Location: signup.php");
exit();
}

如果您正在尝试创建电子商务后端，那么如果您还在学习，则应该从头开始。至少如果您正在考虑存储任何珍贵的数据（电子邮件/密码组合和信用卡）。

就每个用户的表而言，它对数据库的效率不高。不同的想法。

你有：
- 客户（您的用户）
- shipping_addresses（您可以通过customer_id将这些链接链接到客户）
- 推车（再次，您可以通过customer_id将这些链接链接到客户）
- 订单（...您可以通过customer_id）

将这些链接到客户

您只需要插入一个新行，并根据登录用户的id，将该ID添加到目标表的customer_id字段。

实施例。保罗创造了一个新秩序。

$sql = "INSERT INTO orders (id, customer_id, order_number, order_status, created_at, updated_at) VALUES ('', '$logged_in_users_id', '$generated_unique_order_number', '$initial_order_status', '$created_at_timestamp', '$updated_at_timestamp');";
