Question

关于PHP和mySQL，我是一个完整的初学者。我目前正在一个简单的项目中，用户将转到用HTML创建的表单并填写一些信息，并且当他们点击提交时，理论上应该将数据保存到数据库中。我创建了该表格，每次填写该表格时，都会说该帐户已创建，并且没有显示错误。但是，该信息未插入PHPadmin上的数据库中。我一直在尝试通过查看youtube视频和其他stackoverflow论坛来解决此问题，但仍未插入。如果有人能指出我的代码出了什么问题，那将是很好的。我将在下面的代码中附上我认为与之相关的内容。

Here is the main php file

<?php
$email = "";
$password = "";
$errors = array();

// connect to the database
$db = new mysqli('localhost', 'root', '', 'bikeshop');

// check the connection 
if (!$db) {
    die("Connection failed: " . mysqli_connect_error());
}

echo "Connected successfully";

//if the register button is clicked
if (isset($_POST['register'])) {

    $firstname = mysqli_real_escape_string($db, $_POST['firstname']);
    $lastname= mysqli_real_escape_string($db, $_POST['lastname']);
    $streetaddress = mysqli_real_escape_string($db, $_POST['streetaddress']);
    $city = mysqli_real_escape_string($db, $_POST['city']);
    $state = mysqli_real_escape_string($db, $_POST['state']);
    $zipcode = mysqli_real_escape_string($db, $_POST['zipcode']);
    $phonenumber = mysqli_real_escape_string($db, $_POST['phonenumber']);
    $email = mysqli_real_escape_string($db, $_POST['email']);
    $password = mysqli_real_escape_string($db, $_POST['password']);

    // ensure that form fields are filled properly 
if (empty($email)) {
    array_push($errors, "Email is required"); 
}

if (empty($password)) {
    array_push($errors, "Password is required"); 
}

    // if there are no erros, save user to database

    if (count($errors) ==0) {
        $password = md5($password); //password encryption

        $sql = "INSERT INTO customer (FirstName, LastName, Address, City, State, Zip code, PhoneNumber, Email, Password) VALUES ('$firstname','$lastname','$streetaddress','$city','$state','$zipcode','$phonenumber','$email','$password')";

        if(!mysqli_query($db, $sql)) 
        {
            echo 'Account Created';
        }
        else 
        {
            echo 'Account creation failed';
        }

}

}

?>

Answer 1

if(count($errors) == 0)

应使用if(empty($errors))进行更改那是因为您要检查数组是否等于零。数组可以为空，而变量可以为null，零，未定义（尽管它们并不相同）。

Answer 2

尝试一下

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

    $firstname = $_POST['firstname'];
    $lastname= $_POST['lastname'];
    $streetaddress =  $_POST['streetaddress'];
    $city =  $_POST['city'];
    $state =  $_POST['state'];
    $zipcode =  $_POST['zipcode'];
    $phonenumber =  $_POST['phonenumber'];
    $email =  $_POST['email'];
    $password = $_POST['password'];
