Database error: Running CodeIgniter program in Wampserver - php

Question

I'm trying to run a code built with PHP's framework CodeIgniter in another computer, and I've put the program folder in Wampserver's C:/wamp/www folder, but when I open the program in "localhost/program", I get the following error messages:
A PHP Error was encountered
Severity: Warning
Message: mysqli::real_connect(): (HY000/1045): Access denied for user
''#'localhost' (using password: NO)
Filename: mysqli/mysqli_driver.php
Line Number: 201
Backtrace:
File: C:\wamp64\www\program\application\controllers\Home.php
Line: 9
Function: __construct
File: C:\wamp64\www\program\index.php
Line: 315
Function: require_once
That's the file the error are mentioning:
Home.php:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function index()
{
//print_r($this->session->userdata);
//print_r($teste);
$dados = array(
'funcao' =>'index',
'controller' => 'simplex'
);
if (!empty($this->session->userdata('variavel'))) {
$this->session->unset_userdata('variavel');
$this->session->unset_userdata('restricao');
}
$this->template->load('template/template', 'home/home', $dados);
}
public function teste()
{
//print_r($this->session->userdata);
//print_r($teste);
$dados = array(
'funcao' =>'index',
'controller' => 'simplex'
);
$this->template->load('template/template', 'home/teste', $dados);
}
}

I'm not sure what to do, should I install something and change the config files?

Answer 1

What's up guys!
Watch for one of these situations:
Correctly edit the database connection information in the database.php file, located in "application / config / database.php
Define a base URL for your project at: application / config / config.php (line 27), so that it does not try to use its own computer as "localhost" instead of the remote computer. This configuration can be done in application / config / config.php. Search for $ config ["base_url"];
Tip: Sets the IP address of the machine where your application is hosted.
Give permissions to the application folder (or just the logs folder) so that the application can create / write to the files. An example would be to give 755 permission to it.
Maybe this will help.
