You need to change the database config. Go to the following path in your project /application/config/database.php find the dbdriver setting and make sure it's mysqli.

I'm new to Codeigniter PHP framework. When I'm testing my application I get 'Unknown database db_name' error. I have browsed through several sites but didn't found solution for the problem as I'm trying the same to connect with wamp's mysql database. Any help would be appreciable.
Following is database.php in config folder: image describing Test database:
$active_group = 'default';
$query_builder = TRUE;
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'test',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => TRUE,
'db_debug' => TRUE,
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array()
);
I was getting same error when i installed new wampserver 3.2.0, it is an evil it installs MariaDB by default and port 3306 is assigned to it , you cannot even change it. I think codeigniter/php tries to connect to this port by default.
I used following , it worked for me i.e. hostname => 'localhost:3308'
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost:3308',
'username' => 'root',
'password' => '',
'database' => 'soft',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
That's what i did to handle whether db exists or not :
First Change this in application/config/database.php
'db_debug' => (ENVIRONMENT !== 'production')
to
'db_debug' => FALSE;
Then add these two in your controller
$this->load->dbforge();
$this->load->dbutil();
Then check it in your method
if( $this->dbutil->database_exists($this->db->database))
{
echo 'Database Already Exists';
}
else
{
if($this->dbforge->create_database($this->db->database))
{
echo 'Database created successfully !';
}else
{
print_r($this->db->error());
/*
Array (
[code] => 1007
[message] => Can't create database 'my_db'; database exists
)
*/
}
}
I was too getting this error. There are 2 fields in application/config/database.php file that should match up with your actual database:
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
Make sure, the actual DB is of the same type & char_set as mentioned in the above file.
Good Day!
I have this problem using infinityfree.net as my hosting site.
I used codeigniter framework for my code.
The problem is:
An uncaught Exception was encountered
Type: RuntimeException
Message: Unable to locate the model you have specified: Login_model
My code working properly on xampp.
database.php
$active_group = 'default';
$query_builder = TRUE;
$db['default'] = array(
'dsn' => '',
'hostname' => 'HOSTNAME',
'username' => 'USERNAME',
'password' => 'PASSWORD',
'database' => 'DATABASE_NAME',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
Here's my login_model.php
class Login_model extends CI_Model{
public function __construct()
{
parent::__construct();
}
function login($par1,$par2){
//CODE HERE
}
Here's my controller
class Login extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->library('form_validation');
$this->load->helper('url', 'form');
}
public function login()
{
$this->load->model('login_model');
}
PS. i didnt include much more code in controller because thats the only thing that has error and also Im unable to post too much code because of the rule of stackoverflow. Hoping you guys to help me. Thanks in advance
Fixed
I just renamed my login_model to Login_model
