Laravel - How to add new connection to database.php - laravel

Question

I need to use several databases in laravel, and i'm trying to create a form to add a new db connection to connections array in config/database.php.
I don't want to add connections manually, but throught a form.
'connections' => [
'sqlite' => [
'driver' => 'sqlite',
'database' => env('DB_DATABASE', database_path('database.sqlite')),
'prefix' => '',
],
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
'pgsql' => [
'driver' => 'pgsql',
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', '5432'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public',
'sslmode' => 'prefer',
],
],
Thanks

You simple add as many databases to the array as you require then add the connection values to you .env file or to the array valyes like so:
return array(
'default' => 'my_first_db',
'connections' => array(
# Our primary database connection
'my_first_db' => array(
'driver' => 'mysql',
'host' => 'host1',
'database' => 'database1',
'username' => 'user1',
'password' => 'pass1'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
# Our secondary database connection
'my_second_db' => array(
'driver' => 'mysql',
'host' => 'host2',
'database' => 'database2',
'username' => 'user2',
'password' => 'pass2'
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
),
);
Schema::connection('my_second_db')->create('a_new_table', function($table)
{
$table->increments('id'):
});
$users = DB::connection('my_second_db')->select('users');
To add connections through a form you would need to post the data to a template similar to the above and then write to the server, This is a bit of a security risk doing that and would need to be carefull in what you do and how you go about doing it, Posting database data in a request and then just saving the database data to a file is a bit overboard.
You could either setup a config file that has 10 databases pre-defined with PDO and then you could overwrite the settings or save to one of the config files that have no settings assigned.

You can use the config helper and set the config dynamically:
config([
'database.connections.mysql.database' => $dynamicDB,
'database.connections.mysql.username' => $dbUsername,
'database.connections.mysql.password' => $dbPassword,
// Any other dynamically set variables
]);
You could store the parameters in the session and default them to your config file:
config([
'database.connections.mysql.database' => session('db_database', config('database.connections.mysql.database')),
'database.connections.mysql.username' => session('db_username', config('database.connections.mysql.username')),
'database.connections.mysql.password' => session('db_password', config('database.connections.mysql.password')),
// Any other dynamically set variables
]);
Doing this in middleware would give you a little more control over where/when these parameters are being set and used.
