首先，您尚未选择任何数据库.先这样做.
First off, you haven't selected any database yet. Do that first.
您当前的代码:
$mysqli = new mysqli("localhost", "root", ""); // missing fourth parameter
在此添加.
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
session_start();
// connects to the database
$mysqli = new mysqli('localhost', 'root', '', 'DATABASE NAME'); // add the database name (fourth parameter)
if(empty($_SESSION['username'])) {
echo 'not logged in';
exit;
}
$query = "SELECT firstName, lastName, username, password, loyaltyPoints FROM user WHERE username = '{$_SESSION['username']}'";
$result = $mysqli->query($query) or die($mysqli->error);
if($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
// echo $row['firstName'];
// echo $row['lastName'];
// echo $row['username'];
// echo $row['password'];
// echo $row['loyaltyPoints'];
foreach($row as $val) {
echo "$val <br/>";
}
}
}
else {
echo 'not found';
}
?>
