我正在学习php mysql,但我遇到了这个问题.我无法将登录信息插入到我的数据库表中.我的数据库名称是loginapp,表名是用户.请查看我为其创建的代码----
<?php
if(isset($_POST['submit'])){
$username = $_POST['username'];
$password = $_POST['password'];
$connection = mysqli_connect('localhost', 'root', '','loginapp');
if(!$connection){
die("Database connection failed");
}
$query = "INSERT INTO users(username,password)";
$query .= "VALUES ('$username', '$password')";
$result = mysqli_query($connection, $query);
if(!$result){
die('query is faild' . mysqli_connect_error());
}
}
?>
