Question

我试图写一个注册表，首先我试着做OO，但这没有回应，似乎只是清除表格并刷新页面，但没有插入任何数据：

编辑：当前代码：

<?php
session_start();
include 'registrationform.php';
include 'connection.php';

if (isset($_POST['regsubmit'])) 
    {
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$user = $_POST['username'];    
$pass = $_POST['password'];
$query = "INSERT INTO users (firstname, lastname, username, password) VALUES(?, ?, ?, ?)";
$statement = $connection->prepare($query);
//bind parameters for markers, where (s = string, i = integer, d = double,  b = blob)
$statement->bind_param('ssss', $firstname, $lastname, $username, $password);

if($statement->execute()){
     print 'Success! ID of last inserted record is : ' .$statement->insert_id .'<br />'; 
     //$_SESSION['username'] = $_POST['username'];
}else{
     die('Error : ('. $mysqli->errno .') '. $mysqli->error);
}
$statement->close();
?>

注册表

<!DOCTYPE html>
<?php
include 'header.php';
?>
<center>

<html>
<link rel="stylesheet" type="text/css" href="web.css" />


</font>
    <head>


    </head>
    <body> 

    <div id="registrationform">

        Please enter your registration details<br /><br />

        <form method="post" action="registrationsubmit.php">
            First Name:
            <input type="text" name="firstname" />
            <br /><br>
            Last Name:
            <input type="text" name="lastname" />
            <br /><br>
            Username:
            <input type="text" name="username" />
            <br /><br>
            Password:
            <input type="text" name="password" />
            <br /><br>
            <input type="submit" name="regsubmit" value="Submit" />
        </form>

</div>



        </body>
</html>

</center>

OO尝试

<?php
session_start();
include 'registrationform.php';
include 'connection.php';

if (isset($_POST['regsubmit'])) 
    {
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$user = $_POST['username'];    
$pass = $_POST['password'];
$stmt = $connection->prepare("INSERT INTO users VALUES (?, ?, ?, ?)");
$stmt->bind_param('ssss', $firstname, $lastname, $user, $pass);
$stmt->execute();
printf("%d Row inserted.\n", $stmt->affected_rows);  
$stmt->close();
}
?>

由于这不起作用，我尝试在没有OO的情况下进行操作，作为起点。但是现在我给出了错误＆＃34;访问被拒绝用户＆＃39;＆＃39; 10.246.64.24＆＃39; （使用密码：否）＆＃34;，但我的连接很好，我也写了一个完美的登录，所以无法解决。这是我目前的代码：

registrationsubmit.php

<?php
include "connection.php";
include "header.php";
if(isset($_POST['regsubmit']))
{
 mysql_select_db("c3438525_co_uk",$connection);
 $firstname = $_POST['$firstname'];
 $lastname = $_POST['$lastname'];
 $username = $_POST['username']; 
 $password = $_POST['password'];
 $query = "INSERT INTO users (FirstName, LastName, Username, Password) VALUES ('$firstname', '$lastname', '$username', '$password')"; 
 $data = mysql_query ($query)or die(mysql_error()); 
 if($data) { echo "Successfully Registered"; }

 else
 {
  ?>
        <script>alert('error while registering you...');</script>
        <?php
 }
}
?>

Connection.php

 <?php
ob_start();
$connection = mysqli_connect("***", "***", "BFUWGpn3", "***"); 
?>

你正在使用mysqli_连接，你的查询是mysql _

对于registrationsubmit.php

在线上使用一些东西：

$query = "INSERT INTO users (firstname, lastname, username, password) VALUES(?, ?, ?, ?)";
$statement = $connection->prepare($query);
//bind parameters for markers, where (s = string, i = integer, d = double,  b = blob)
$statement->bind_param('ssss', $firstname, $lastname, $username, $password);

if($statement->execute()){
     print 'Success! ID of last inserted record is : ' .$statement->insert_id .'<br />'; 
     //$_SESSION['username'] = $_POST['username'];
}else{
     die('Error : ('. $mysqli->errno .') '. $mysqli->error);
}
$statement->close();

请参阅：http://php.net/manual/en/mysqli.insert-id.php
