Codeigniter Create a database and table outside of config/database.php - php

Question

I am attempting to create a database and table for each customer registered from my codeigniter site, i am looking at the dbforge documentation and tried below code.
but error appeared, i want to make it dynamic for each customer so putting it on config/database.php is not available is there a way to prevent this?
i am new with codeigniter not sure if below code is also correct.
You have specified an invalid database connection group
(customer_LYWA) in your config/database.php file.
public function create_customer_database($code){
$database = $this->dbutil->database_exists('customer_'.$code);
if($database){
return "";
}else{
$this->dbforge->create_database('customer_'.$code);
$fields = array(
'blog_id' => array(
'type' => 'INT',
'constraint' => 5,
'unsigned' => TRUE,
'auto_increment' => TRUE
),
'blog_title' => array(
'type' => 'VARCHAR',
'constraint' => '100',
),
'blog_author' => array(
'type' =>'VARCHAR',
'constraint' => '100',
'default' => 'King of Town',
),
'blog_description' => array(
'type' => 'TEXT',
'null' => TRUE,
),
);
$this->dbforge->add_field($fields);
$this->dbforge->add_key('blog_id', TRUE);
// gives PRIMARY KEY (blog_id)
$this->dbforge->add_key('blog_title');
// gives KEY (blog_title)
$otherdb = $this->load->database('customer_'.$code, TRUE);
$this->dbforge->create_table('blog');
return "created";
}
}

I think you are trying to create a table for each customer.
With that, I think you are confusing databases with tables. databases contain tables, so you will need to connect to the correct database in config/database.php, and use your script to create tables inside that database.
You don't need to create a new database for each customer. That would make things 100 times harder than they should be, and will be very hard to maintain.
