Answer 1

mysqli_error()调用需要一个参数。参数应该是连接句柄。

if(!$result) {
   die('Query FAILED' . mysqli_error($connection));

这会告诉您查询中的实际错误，即参数列表部分中'$email' '$phone',之间缺少的逗号。

$query = "INSERT INTO userinfo
            (name, email, phone, website, info, budget) 
          VALUES 
            ('$username', '$email', '$phone', '$info', '$budget', '$website')";

Answer 2

数据库连接不对。
查询不正确。缺少，（逗号）betwwen '$email'和'$phone'
放mysqli_error($connection)。需要参数。

使用此编辑的代码。

<?php 
if(isset($_POST['submit'])) 
{
    $DB_HOST = "localhost";
    $DB_USER = "root";
    $DB_PASS = "";
    $DB_NAME = "dd777";

    $connection = mysqli_connect($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);

    $username = $_POST['username'];
    $email = $_POST['e-mail'];
    $phone = $_POST['phone'];
    $info = $_POST['info'];
    $budget = $_POST['budget'];
    $website = $_POST['website'];

    $query = "INSERT INTO userinfo(name, email, phone, website, info, budget) ";
    $query .= "VALUES ('$username', '$email','$phone', '$info', '$budget', '$website')";

    $result = mysqli_query($connection, $query);

    if(!$result) {
        die('Query FAILED' . mysqli_error($connection));

    } else {

    echo "Record Create"; 

        }
    }   
}
