Question

所以我将一些MySQL Rails导入到一个表单中，但似乎有一个问题，数据库没有连接，它说没有选择数据库，我在constants.php中有我的数据库连接参数，并且它们在其他工作正常网站的页面，命令中也没有语法错误，请帮帮我。谢谢！

<?php
    require_once 'classes/Membership.php';
    require_once 'includes/constants.php';
    $membership = New Membership();
    $membership->confirm_Member();
    $con = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME) or 
    die('Error connecting Database');
?>

我建议您使用面向对象的方式使用 MySQLi

对MySQL执行查询

您可以在此处查看示例 http://in2.php.net/manual/en/mysqli.query.php

自PHP 5.5起不推荐使用MySQL

将MySQL行导入表中
