Unable to connect to database. - shahzaibahmed52 - 10-08-2023
HI,
I am having a problem creating a model and using it in my controller. I am receiving the following error when trying to do so.
Quote:APP\Models\loginModel::__construct(): Argument #1 must be of type Codeigniter\Database\ConnectionInterface,
Codeigniter\Database\MySQLI\Connection given.
Here is the code that I am using for my model and controller.
Code:
<?php
namespace APP\Models;
use App\Database;
use CodeIniter\Database\ConnectionInterface;
use CodeIgniter\Database\MySQLi\Connection;
class loginModel
{
protected $db;
public function __construct(ConnectionInterface &$db)
{
$this->db =& $db;
}
public function getloginUser()
{
$builder = $this->db->table("loginusers");
$result = $builder->get()->getresults();
return $result;
}
}
////-----------------------Controller------------------------////Code:
<?php
namespace App\Controllers;
use App\Models\LoginModel;
class Login extends BaseController
{
public function index()
{
return view('login');
}
public function validateLogin()
{
$db = db_connect();
$model = new LoginModel($db);
$username = $this->request->getpost("username");
$password = $this->request->getpost("password");
$password = md5($password);
echo "<pre>";
print_r($model->getloginUser());
echo "</pre>";
}
}Can you guys help me to fix the issue that I am facing?

That is strange, because Codeigniter\Database\MySQLI\Connection implements Codeigniter\Database\ConnectionInterface.

You Posted this:
PHP Code:
use CodeIniter\Database\ConnectionInterface;
It has a typo and should be:
PHP Code:
use CodeIgniter\Database\ConnectionInterface;
Typo in your post or in your code?
