Question

有一段时间我一直试图弄清楚php和mysql表单以及它们是如何工作的。此时我停了下来，因为我的代码不会将数据插入到mysql数据库中。

在我的脚本中，我收到错误

＆＃34;抱歉，发生了错误！＆＃34;

我的代码：

    <?php
session_start();
if(isset($_SESSION['users'])!="")
{

}
include('../System/config.php');

if(isset($_POST['btn-signup'])){
 $username = $_POST['username'];
 $password = $_POST['password'];
 $email = $_POST['email'];
 $region = $_POST['region'];
 $country = $_POST['country'];
 $state = $_POST['state'];
 $city = $_POST['city'];
 $name = $_POST['name'];
 $surname = $_POST['surname'];
 $homepage = $_POST['homepage'];

 if(mysql_query("INSERT INTO users(Username, Password, Email, Region, Country, State, City, Name, Surname, Homepage) VALUES('$username', '$password', '$email', '$region', '$country', '$state', '$city', '$name', '$surname', '$homepage')"))
 {
  ?>
        <script>alert('You have sucesfully registred your account!');</script>
        <?php
 }
 else
 {
  ?>
        <script>alert('Sorry, there was an error!');</script>
        <?php
 }
}
?>

这就是我的数据库表的外观：

PHP表单不会将数据插入到mysql数据库中
