PHP MODx mysql解析错误？我在哪里更改设置？

Question

嗨我在网站上使用MODx，但数据库出了问题。任何想法如何改变PHP指向我的数据库？

MODx encountered the following error while attempting to parse the requested resource: 
« PHP Parse Error »

Answer 1

如上所述，我会检查使用phpAdmin，您的登录凭据到您的modX数据库是正确的第一。一旦你确定这是工作确定，然后在镆铘数据库配置相信文件

<site_home_directory>/manager/includes/config.inc.php

右键在顶部定义它有这个块，你应该能够相应地编辑。

<?php 
/** 
* MODx Configuration file 
*/ 
$database_type = 'mysql'; 
$database_server = 'localhost'; 
$database_user = 'db_username'; 
$database_password = 'mypassword'; 
$database_connection_charset = 'utf8'; 
$database_connection_method = 'SET NAMES'; 
$dbase = '`db_name`'; 
$table_prefix = 'modx_'; 

希望这有助于

Answer 2

在文件的开头，它说它无法连接到数据库，尝试连接到数据库，然后执行您的查询。

使用mysql_connect功能连接到数据库。

另外检查以确保您为数据库连接指定了正确的凭据。
