我现在是该公司的实习生，我将为该网站创建注册和登录表单。
目前我正面临注册问题。
我在教程中声明了所有内容，但仍然遇到这些错误而无法弄清楚。
这是php脚本：
<?php

}else{
$user_name = mysqli_real_escape_string($con, trim($_POST['user_name']));
//validation to check if the username posted is in use.
if($check = $connection->query("SELECT * FROM student WHERE username = '$user_name'")){
if($check->num_rows){
$errors['user_name'] = 'Username in use';
}

$errors['user_name'] = 'the query did not work';

请注意，php脚本和html形式都在一个文件中。
答案 0 :(得分：1)
更改training_index.php中的变量名称
$conn and $connection to $conn
因为在connection.php文件中，您将数据库连接变量名称称为
$con = new mysqli($servername, $username, $password, $dbname);
