Laravel url alias, mismatch in url generation - php

Question

I have a Laravel 5.2 application where I want to display the same page on 2 different domains / routes. I have it working using the following route structure:
The routes to my primary domain:
Route::group(['domain' => 'www.primarydomain.com',
'prefix' => 'demo-page']), function(){
Route::get('/my-page', 'MyController#index');
Route::get('/my-second-page', 'MyController#getPageTwo');
}
The routes to my secundary domain (note: no prefix!):
Route::group(['domain' => 'www.secundarydomain.com',]), function(){
Route::get('/my-page', 'MyController#index');
Route::get('/my-second-page', 'MyController#getPageTwo');
}
The idea is that both routes will work, and they do. Both www.secundarydomain.com/my-page and www.primarydomain.com/demo-page/my-page work.
The issue is when I now want to generate a link to my second page. For building my URL's in my views, I'm using the following function to generate a link to my-second-page:
url('/my-page')
This function always generates a link to www.primarydomain.com/my-page, while I need a link to www.primarydomain.com/demo-page/my-page.
Is there any easy solution to resolve this? Can this be resolved using middleware, or will a custom URL function be needed?
Expected results:
url('my-page') on www.primarydomain.com should generate a link to www.primarydomain.com/demo-page/my-page
url('my-page') on www.secondarydomain.com should generate a link to www.secondarydomain.com/my-page

Answer 1

Easiest way to do that is to create your own helper, like custom_url() and use it instead of url().
You can look how original url() helper works and create similar one. Look here:

You can assign aliases to your routes.
Route::group(['domain' => 'www.primarydomain.com', 'prefix' => 'demo-page']), function(){
Route::get('/my-page', [
'as' => 'my_page_prefixed',
'uses' => 'MyController#index'
]);
Route::get('/my-second-page', [
'as' => 'my_second_page_prefixed'
'uses' => 'MyController#getPageTwo'
]);
}
And then you can call your aliased route on your blade templates by using {{ route('my_page_prefixed') }} or any other alias.
