PHP - include_once/include 不工作

PHP - include_once/include not working

我正在为一个学校项目开发一个非常简单的 CMS 系统,但遇到了一些麻烦。

现在我的网页是这样设置的:

在我的 header.php 我有这个,还有其他杂项 HTML:

<?php require_once('php/constants.php'); require_once("php/functions.php"); ?>

对于 constants.php - 包含我能想到的每个已定义常量,因为我宁愿在此处更改一个常量,也不愿在我的代码中搜索以查找我在其他地方可能拥有的任何实例。

For Functions.php - 包含我为在该 CMS 上使用而创建的所有函数。包含从我使用 PHPMailer 的电子邮件功能到使用 MeekroDB 进行数据库交互的注册和登录的所有内容。

问题就出在这里。

在我的帐户注册页面上,有类似这样的内容

//get the username, password, first/last name, and send it to register function.
        $firstName = $_POST['first_name'];
        $lastName = $_POST['last_name'];
        $password = $_POST['password'];
        $email_address = $_POST['email_address'];

        //register the user. where register() is in functions.php
        if(register($email_address, $password, $firstName, $lastName))
        {
            echo "REGISTRATION SUCCESSFUL";
        }
        else
        {
            echo "REGISTRATION UNSUCCESSFUL";    
        }

在我的 functions.php 文件中,我使用 MeekroDB 提到我使用的 DB::QUERY 赋值来声明我的数据库信息。

//MeekroDB - Used for database CRUDding
require_once("php/meekrodb.php");
DB::$user = 'root'; //yes i'll change this later
DB::$password = ''; //this too
DB::$dbName ="testDB";

在实际的寄存器函数中我有这个:

function register($email, $password, $firstName, $lastName)
{
    //check to see if the user already exists
    //poll the DB to see if the email is already in there.
    $results = DB::QUERY("SELECT email FROM users WHERE email = %s", $email);

    //if there is a row in the DB with this email...
    if(DB::count() >= 1)
    {
        return false;
    }
    else
    {
        //lets prepare the user for insertion into the database.
        $username = $firstName . '_' . $lastName;
        //generate a salt for database insertion and password hashing
        $salt = hash('sha512', uniqid(mt_rand(1, mt_getrandmax()), true));
        $password = hash('sha512', $password . $salt);

        //create the insert statement array for insertion.
        $insertionArray = 
        array(
            'username' => $username,
            'password' => $password,
            'email'    => $email,
            'salt'     => $salt,
            'isAdmin'  => 0
        );

        //insert the new user into the database.
        DB::INSERT('users', $insertionArray);

        //Send a registration email to the new user.
        //Send an email to the user stating they've registered.
        $mailer = createMailer();

        //set the contents of the email
        $mailer->MsgHTML(generateEmail_Registration($username));

        //set the destination address
        $mailer->AddAddress($email, $firstName . ' ' . $lastName);

        if($mailer->Send())
        {
            return true;
        }
        else
        {
            return false;
        }
    }

}       

对我来说,这应该可行。

但是:

每当我尝试 运行 register() 函数时,我都会遇到大量涉及 MeekroDB 的错误,而且我不是 100% 确定如何修复它们(无论是 INCLUDE 问题,还是可能是meekroDB 的东西?)

这是我遇到的错误。

REGISTRATION UNSUCCESSFUL //of course.

我认为这与我包含各种 PHP 文件的方式有关,并且在 return 中以某种方式扰乱了我的 MeekroDB 连接。

如果你们需要更多信息,请告诉我,但我认为我已经在 table.

上发布了所有内容

我不常post来这里,所以如果我在某处错过了某种礼仪,我提前道歉。

谢谢! :)

如果您按照 meekrodb.php 文件进行操作,第一个错误是在您刚刚尝试连接的 $mysql 对象上调用的(查看 meekrodb.php 文件看看我在说什么)所以这些错误可能与连接信息错误或连接到数据库的其他问题有关,因此其他功能失败。

查看更多信息性错误的一种简单方法是尝试使用他们的 $throw_exception_on_error 函数:

function register($email, $password, $firstName, $lastName)
{
    //check to see if the user already exists
    //poll the DB to see if the email is already in there.
    DB::$error_handler = false; // since we're catching errors, don't need error handler
    DB::$throw_exception_on_error = true;

    try {
      $results = DB::QUERY("SELECT email FROM users WHERE email = %s", $email);
    } catch(MeekroDBException $e) {
      echo "Error: " . $e->getMessage() . "<br>\n"; // this should be a better error...
      echo "SQL Query: " . $e->getQuery() . "<br>\n"; // SELECT email FROM users...

    }
    ...

如果这是 include/include_once 的问题,您会收到完全不同的消息。我首先建议使用最新版本的库,即 2.3,最重要的是,检查你使用的 PHP 的版本。

据我所知,MySQLi 连接很可能存在问题,并且根据您的 PHP 版本,确保连接未失败的检查存在问题,如本页所示http://php.net/manual/en/mysqli.connect-error.php

Warning The mysqli->connect_error property only works properly as of PHP versions 5.2.9 and 5.3.0. Use the mysqli_connect_error() function if compatibility with earlier PHP versions is required.

由于没有连接,这将导致您在此表单中看到多个警告。

Warning: mysqli::method_name(): invalid object or resource mysqli
