您好，我正在网站上使用 MODx，但数据库出现问题。知道如何更改 PHP 以指向我的数据库吗？

如前所述，我将首先使用 phpAdmin 检查您的 modX 数据库的登录凭据是否正确。一旦你确定这工作正常，那么在 modX 中，我相信数据库配置是在文件中定义的
<site_home_directory>/manager/includes/config.inc.php在顶部有这个块，您应该能够对其进行相应的编辑。
<?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_';
希望这有帮助
