Hi guys.

You can easily set up a connection to my database by database.php file. The problem is that when I try to configure more than one connection my application crashes. How do I configure multiple connections in database.php power and give a CRUD in Model.php?

If you're autoloading you should specify the default and load the second one manually.

Can you give an example ?

$DB1 = $this->load->database('group_one', TRUE);
$DB2 = $this->load->database('group_two', TRUE);

$DB1 = $this->load->database('group_one', TRUE);
$DB2 = $this->load->database('group_two', TRUE);

I will detail my nonfunctional code?

$active_group = 'dbone';
$query_builder = TRUE;

$db['dbone'] = array(
'dsn' => '',
'hostname' => '000.000....',

'password' => '',

File_model.php

class File_model extends CI_Model {

public function insert() {
$dbs = $this->load->database('screens', TRUE);
$email = 'myemail';
$this->db->insert('ws_user_on', $$email);
}
}

I can not see error? And simply does not work?

1st: You selected a database config named 'screens'? but your database configs are dbone and dbtwo.
2nd: If 'screens' did exist you assigned it to a object $dbs BUT used the $this->db object? that would be $dbs->insert('ws_user_on', $$email);
3rd: You tried to use a variable named myemail because you used a variable variable and myemail doesn't contain anything because it's not declared.

I made the settings as and did not work ?

[seasenx6]

$this->one = $this->load->database('dbone', true);
$this->two = $this->load->database('dbtwo', true);

$this->one->select('*')->from('some_table')->get();

$this->two->query('select * from some_table');
