WHMCS配置模块从mysql阵列外部数据库服务器中的ConfigOptions下拉列表

问题描述

目前我正在制作一个创建帐户并挂起和取消挂起的模块，在我的_ConfigOptions中有一个下拉菜单，它必须在另一台服务器上获取mysql查询的值，该服务器已在模块中注册， _ConfigOptions我从默认的$ params数组中获取值，就像这样。

$serverip = $params["serverip"];
$serverusername = $params["serverusername"];
$serverpassword = $params["serverpassword"];
$serverport = $params["serverport"];

然后我可以进行查询并连接到外部服务器。我的问题是，当我想从_ConfigOptions函数获取$ params时，由于这里无法获取该变量，我的问题是是否可以通过创建另一个函数来进行该查询？我将把代码部分。

_ConfigOptions

function ModuleName_ConfigOptions()
{
    $api = new \whmcsui\Api();
    
    return array(
        // a text field type allows for single line text input
        'Package' => array(
            'Type' => 'text','Size' => '25',),'Credits' => array(
            'FriendlyName' => 'Amount of Credits','Type' => 'dropdown','Options' => "1,2,3,4,5,6,7,8,9,10,11,12",'dealer' => array(
            'FriendlyName' => 'Choose Dealer:','Options' => $api->getResellers($params),// this is te function to call
        ),'comments' => array(
            'Type' => 'text','Size' => '100','trialPackage' => array(
            'FriendlyName' => 'Trial Package','Type' => 'radio','Options' => 'Yes,No','Description' => 'Is this trial package? (For \"Yes\" see the text box for entering trial period)',);
}

这是API调用查询结果的代码

public function getResellers($serverip,$serverusername,$serverpassword,$serverport){
        
        $serverip = $params["serverip"];
        $serverusername = $params["serverusername"];
        $serverpassword = $params["serverpassword"];
        $serverport = $params["serverport"];
        
        $database='xtream_iptvpro';
        $dealer=$reseller;
        
        $host = $serverip.':'.$serverport;
        $user = $username;
        $passs = $password;
            
        $connection=mysqli_connect($host,$serverpassword);
        if (!$connection) {  die('Not connected : ' .$host.'|'. $serverusername.'|'. $serverpassword );} 
            
        $db_selected = mysqli_select_db($connection,$database);
        if (!$db_selected) {
             die ('Can\'t use db : ' . mysqli_error($connection));
        }
        
        $query = "SELECT id,username FROM `reg_users`";
        $result =mysqli_query($connection,$query);
            
        $dbdata = array();
        
        while ( $row = $result->fetch_assoc())  {
        $dbdata[$row["id"]]=$row["username"];
        }                   
                        
        return $dbdata;

    }

结果是未连接：||。成为原因。数组$ params为空，请帮助
