Set Default Prefix in CakePHP 3 based on sub domain - php

Question

I want to build multiple sub domain which point to same source code of CakePHP v3
Scenario is
If domain is "admin.localhost.com" then prefix value should be admin.
If domain is "xyz.localhost.com",'abc.localhost.com' or any on sub domain then prefix value should be vendor
If domain is "localhost.com" or "www.localhost.com" then prefix value should be false as cakephp 3 have by default.
I have tryied to findout from CakePHP 3 document. but I didint get how to set default prefix.
Thanks in Advance

Answer 1

I got Answer of my question myself
We have to set prefix in config/routs.php by exploding HTTP_HOST
$exp_domain= explode(".",env("HTTP_HOST"));
$default_prefix=false; // default prefix is false
if(count($exp_domain)>2 && $exp_domain[0]!="www")
{
if($exp_domain[0]=="admin") $default_prefix="admin";
else $default_prefix="vendor";
}
if($default_prefix=="admin")
{
// default routes for vendor users with base scope and pass prefix as admin ($default_prefix)
Router::scope('/', function ($routes) use($default_prefix) {
$routes->connect('/', ['controller' => 'admins', 'action' => 'dashboard','prefix'=>$default_prefix]);
$routes->connect('/:action', ['controller' => 'admins','prefix'=>$default_prefix]);
$routes->connect('/:controller/:action', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);
$routes->connect('/:controller/:action/*', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);
});
}
else if($default_prefix=="vendor")
{
// default routes for vendor users with base scope and pass prefix as vendor ($default_prefix)
Router::scope('/', function ($routes) use($default_prefix) {
$routes->connect('/', ['controller' => 'vendors', 'action' => 'dashboard','prefix'=>$default_prefix]);
$routes->connect('/:action', ['controller' => 'vendors','prefix'=>$default_prefix]);
$routes->connect('/:controller/:action', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);
$routes->connect('/:controller/:action/*', ['controller' => 'controller', 'action' => 'action','prefix'=>$default_prefix]);
});
}
else
{
// default routes for normal users with base scope
Router::scope('/', function ($routes) use($default_prefix) {
$routes->connect('/', ['controller' => 'users', 'action' => 'dashboard');
$routes->connect('/:action', ['controller' => 'users');
$routes->connect('/:controller/:action', ['controller' => 'controller', 'action' => 'action');
$routes->connect('/:controller/:action/*', ['controller' => 'controller', 'action' => 'action');
});
}
So main trick is need to pass prefix on root scope.
