PHP 7.2.7 警告：使用未定义常量

Question

所以在我点击 index.php resgitration 表单上的提交之后。一切顺利，名称、电子邮件和密码已从我的数据库中保存。但是有一个警告让我很生气。

Use of undefined constant result_query - assumed 'result_query' (this will throw an Error in a future version of PHP)

出现。

说是第26行

这是我的 function.php 警告来源代码。

<?php include "db.php" ?>
<?php

function createAccount(){
global $connection;
if(isset($_POST['submit'])){

    $name = $_POST['name'];
    $email = $_POST['email'];
    $password = $_POST['password'];

    $name = mysqli_real_escape_string($connection, $name);
    $passowrd = mysqli_real_escape_string($connection, $password);

    $hashFormat = "y$"; // blowfish encryting
    $salt = "dikoalampasswordqweqwe";
    $hashAndSalt = $hashFormat . $salt;

    $password = crypt($password, $hashAndSalt);

    $query = "INSERT INTO accounts_registered(name, email, password) ";
    $query .= "VALUES ('$name', '$email', '$password')";

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

    if(!result_query){
        die("Query Failed" . mysqli_error($connection));
    }
    else {
      $message = "Account Registered";
      echo "<script type='text/javascript'>alert('$message');</script>";

      }
   }
}


?>

Answer 1

if(!result_query) 应该是 if(!$result_query)

Answer 2

而不是

if(!result_query)

尝试

if(!$result_query)
