我希望你们中的一位专家可以在我的PHP中指出我的数据库连接代码中的错误。我的页面根本不起作用。
我正在尝试在我的数据库中创建新用户。我检查了表格中的所有名字，它们完美匹配。
这是我的功能：
<?php include('connection.php'); ?>
<?php
function createUser()
{
if(isset($_POST['submit']))
{
global $connection;
$username = $_POST['username'];
$password = $_POST['password'];
$firstName = $_POST['firstName'];
$lastName = $_POST['lastName'];
$emailAddress = $_POST['emailAddress'];
$phoneNumber = $_POST['phoneNumber'];
$privilege = $_POST['privilege'];
$query = "INSERT INTO users(username,password,firstName,lastName,emailAddress,phoneNumber,privilege)";
$query .= "VALUES ('$username', '$password','$firstName','$lastName','$emailAddress','$phoneNumber','$privilege')";
$result = mysqli_query($connection, $query);
if(!$result)
{
die('Query Failed' . mysqli_error());
}
else
{
echo '<div class="modal-footer">
<div class="alert alert-success alert-block fade in" id="successAlert">
<button class="close" type="button" data-dismiss="alert" aria-label="close"><span aria-hidden="true">×</span></button>
<h4>Success!</h4>
<p>New user registered successfully</p>
</div>
</div>';
die;
}
}
}
?>
这是我的HTML： 我将header.php调用到我的主页，但函数也在那里调用。
<?php include('connection.php'); ?>
<?php include('functions.php'); ?>
<?php createUser(); ?>
