Laravel - Change Database Connection for a specific URL? - php

Question

I am fairly new to using laravel framework. I have the following requirement. I have a domain - example.com, and its entire code stack is running in laravel. Lets say in the config default database connection is - 'db1'
Now, if the url becomes - example.com/country - I want the default database connection to become - 'db2'
And also I want the base URL to be changed to example.com/country, since all the modules are going to be the same. Only the database connection is going to change here.
Could someone help me out here?

I would do it the following way:
Put the list of allowed countries into config file (countries.php) .
In routes.php:
// choosing country
$country = '';
if (in_array(Request::segment(1), Config::get('countries'))) {
$country = Request::segment(1);
}
// making route for top level
if ($country != '') {
Route::any( '/', 'MainPage#index');
}
// making routes optionally prefixed by country
Route::group(
array('prefix' => $country,
function () {
// here all routes
});
In database.php where you have defined your connection you could add another connections for example:
'germany' => array(
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'germany_connection',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
),
Now in the same file (although you should probably move it somewhere else) you can do:
if ($country == 'germany') {
DB::disconnect();
Config::set('database.default','germany');
DB::reconnect();
}
You can of course add many conditions here or if you have defined connection for each allowed country you can simply do:
if ($country != '' ) {
DB::disconnect();
Config::set('database.default', $country);
DB::reconnect();
}
It should work however I haven't tested it

I've made something similar using environments.
Add a new rule when detecting the environment to parse the URL and change it to the new environment. Then you can add a directory for the new environment where you set up the new database, base URL, etc.
