我刚刚编写了一个 WHMCS 插件模块，它在我的服务器上运行得很好；然而，其他尝试使用它的人并没有成功。有 2 个问题...
1) 我使用 WHMCS 许可证插件；但是，他们的远程计算机似乎并未成功连接到我的计算机以验证许可证。我使用 WHMCS 提供的代码来处理连接和验证。不知道还要检查什么...有什么想法吗？
2）我有一个数据库，我的脚本会检查该数据库以查看用户是否拥有最新版本的脚本。从我的本地计算机访问数据库效果很好，并且使用 % 通配符启用了 RemoteSQL，因此任何人都应该能够连接，但远程计算机似乎无法连接。这是我的信息...
$link = mysql_connect('gjinternetsolutions.com', 'gj_Guest', 'Password1');
mysql_select_db("gj_Software", $link);
$query = "SELECT * FROM `VersionCheck` where `Software`='RedemptionFee'";
... additional code to display the results
有人能够成功远程连接上述数据库吗？
============更新==========
上面的第二个问题已经解决了。我们仍然遇到许可代码问题......这就是我们所拥有的......

是的，我可以使用上面的详细信息进行连接。
查询运行：
SELECT * FROM `gj_Software`.`VersionCheck` where `Software`='RedemptionFee'
结果：
# Software, Version, URL
'RedemptionFee', '1.0', 'http://GJinternetSolutions.com/home/upgrade.php?type=package&id=660'
希望这有帮助。
