Where in Yii2 init some subdomain settings? - php

Question

I have site with subdomains (news.site.com, events.site.com etc).
I am added to config my custom url rule, who find by requested url article in DB and call article controller with action show
for example: 'news.site.com/some-article-with-custom-url'
I want find in db article with url = 'some-article-with-custom-url' and call actionShow() in ArticleController.
But on news.site.com and events.site.com i want find articles with different site_id (column in db)
news.site.com - select * from article where site_id = 1 ...
events.site.com - select * from article where site_id = 2 ...
where I can init some subdomains settings, if on UrlManager level I must already have this settings?
'urlManager' => [
'rules' = [
...
[
'class' => 'common\components\ArticleUrlRule'
],
]
]
Implementation of parse req of this class:
public function parseRequest($manager, $request) {
$articleId = Article::getArticleIdByUrl($request->pathInfo);
if ( !empty($articleId) ) {
return [
'article/show',
[
'id' => $articleId
]
];
}
return false;
}

Answer 1

The easiest way to deal with this, probably there are other ways, starts from defining each sub-domain as a site on your web server. As you regarded, you may have three sites, one main and two sub-domains, make two additional copies of the web folder naming them news and events respectively, so in your Yii2 project root directory you will have web, events and news directories which they are going to be three documents root for three websites on your web server.
In the index.php of each web directory define a variable or a constant to express the site id to use it in your application when it is going to be needed:
<?php
defined('SITE_ID') or define('SITE_ID', x); // where x is an integer
// comment out the following two lines when deployed to production
defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'prod');
...

There are a couple of way of doing this, ranging from easy and hacky to hard and well formed.
I think the best way to do this is to have one URL config:
'urlManager' => [
'rules' = [
[
'<controller:[\w-]+>/<id:\d+>'=>'<controller>/view',
]
]
]
Then in your ArticleController:
public function actionShow($id)
{
// This might be better as a definition list stored in config or something
$site = null;
$sub = Yii::$app->request->hostInfo; // Put some logic here to split out subdomain
switch($sub){
case 'site1':
$site = 1;
}
$articleId = Article::find()->where(['id' => $id, 'site' => $site]);
}
Sort of thing. It can be made more robust and, in general, better from there but I believe that's a good way to do it.
