从joomla验证登录凭据！核心结构

Question

我正在为joomla开发一个插件！但是考虑到脚本的复杂性，我在核心结构之外设计了它。

现在我遇到的唯一问题是，只有在用户有权限的情况下，才允许用户以管理员身份登录一次，并遵循我的插件文件夹。

我的插件在：( pathdotcom/test)文件夹中，所有内容都可以正常工作，但可以向公众开放。

到目前为止，我已经在(test/index.php)中尝试了以下代码：

// Load Joomla! configuration file
require_once('../configuration.php');
// Create a JConfig object
$config = new JConfig();
//import variables
$dbhostname     = $config->host;
$dbusername     = $config->user; 
$dbpassword     = $config->password;
$dbdatabase     = $config->db;
$dbprefix       = $config->dbprefix;
$secret         = $config->secret;

// Get these from your form...

   $username_for_check = 'admin'; // this username should be in your database = change it

   $password_for_check = 'passw'; //this password should be in your database encrypted = change it

//connect to db
   $mysqli = new mysqli($dbhostname,$dbusername,$dbpassword,$dbdatabase);

   if ($result = $mysqli->query('SELECT j.username,j.password FROM '.$dbprefix.'users j WHERE j.username="'.$username_for_check.'" LIMIT 1;')) {

      if ($result->num_rows == 0){
         echo 'Username does not exist.';
      }
      else{
         while ($row = $result->fetch_object()) {

            //Grab username and password from table #__users
            $joomla_user = $row->username;
            $joomla_pass = $row->password;


            $pass_array = explode(':',$row->password);// <== Here not sure!!
            //but it should be the magic behind it.. for me doesn't work  in joomla 3.5 and above apparently as encryption method changed
            //my password does not have a colon in between

            //\\===\ Those are just echos to visually check if the password was matched /==//\\

            echo '[USER:] '.$joomla_user.'<br>';

            echo '[PASS:] '.$joomla_pass.'<br>';

            echo '[HASH:] '.$joomla_hash = $pass_array[0].'<br>';

            echo '[SALT:] '.$joomla_salt = $pass_array[1].'<br>';

            echo '[SECRET:] '.$secret.'<br>'; //secret maybe of help, just put it ready for testing

            echo '[CHECK:] '.md5($password_for_check.$joomla_salt).'<br>';
            //=======================================================================//
         }

         if($joomla_hash == md5($password_for_check.$joomla_salt)){ //Old approch for validating according to various prehistoric posts

            echo 'Username and password combination validated.';

         }
         else{
            echo 'Invalid password for username.';
         }

      }

   }
   else {
     echo 'LOGIN VALIDATION: MySQL Error - '.$mysqli->error;
   }
   //close db
   $mysqli->close();

正在尝试返回匹配项并验证注册用户，然后再继续。

我希望有人在3.5和更高版本上有一个解决方案。

提前感谢
