這是我的第一個問題。我希望我能找到答案。 正如標題所說，我無法添加使用我在html中創建的表單的用戶，並且我無法將使用php函數的用戶添加到數據庫中。無法在mysql數據庫中使用php表單添加用戶
db.php中
<?php
$db['db_host'] = 'localhost';
$db['db_user'] = 'root';
$db['db_pass'] = '';
$db['db_name'] = 'cms';
foreach($db as $key => $value){
define(strtoupper($key),$value);
}
$con = mysqli_connect(DB_HOST,DB_USER,DB_PASS,DB_NAME);
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
//you need to exit the script, if there is an error
exit();
}
?>
add-user.php
<?php
require_once('inc/top.php');
if(!isset($_SESSION['username'])){
header('Location:login.php');
}
else if(isset($_SESSION['username']) and $_SESSION['role'] =='author'){
header('Location:index.php');
}
?>

我已經做了很多的搜索，但沒有找到它的工作代碼，並添加用戶。每當我嘗試添加一個用戶作爲「作者」或「管理員」它說「用戶沒有被添加」。 在此先感謝
你能解決它請提供您收到的錯誤？ – pinoyCoder
錯誤是「用戶未被添加」 –
嘗試將mysqli錯誤添加到您的字符串以查看錯誤。 '''$ error =「用戶沒有被添加」。 mysqli_error（$ con）;''' – mirsch
