How to change database name before authentication in laravel 5.1 - php

Question

I have multiple database. I want to change db name based on the url dynamically. How can I set particular db before authentication.
I want to change database from authentication to through out the application.
For ex.
If url is like lara.local.com/comapny1
then it will select database company1
If url is like lara.local.com/company2
then it will select database company2
Based on the selected database authentication will be done and selected database will be used for that user.

Answer 1

Make entry for second database in config/database.php
'company1' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => env('DB_DATABASE', 'database1'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
'company2' => [
'driver' => 'mysql',
'host' => env('DB_HOST', 'localhost'),
'database' => 'database2',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
],
By default your queries will use the mysql connection to change connection to 'company1'
DB::connection('company1')->select($query);
Additionally you can set database connection for Model
$someModel = new MyModel;
$someModel->setConnection('company1');
You can use the Request::is() to get URI from URL
if(Request::is('company1')){
//change database to company1
Config::set("database.connections.company1.database", 'company1');
}
elseif(Request::is('company2'){
Config::set("database.connections.company1.database", 'company2');
}

You can achieve this thing with below steps:
1 Define multiple connection into database.php for example:
'db1' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'db1_connection',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
2 Use connection based on conditional statement(You should move this code else)
//Check url that contains 'MYCODE'
if ('URL Contains' == 'MYCODE') {
DB::disconnect();
Config::set('database.default','db1');
DB::reconnect();
}
else {
DB::disconnect();
Config::set('database.default','db2');
DB::reconnect();
}
It should work for you, however I haven't tested it. Reference taken from answer by Marcin Nabialek

You can do this in AppServiceProvider's boot() like this
public function boot()
{
if($this->app['request']->getHost()=='test.com') {
Config::set('database.default','mysql');
}
else{
Config::set('database.default','mysql1');
}
}
