Getting base URL in Yii 2

Question

I am trying to get the base URL for the project in Yii 2 but it doesn\'t seem to work. According to this page you used to be able to do:

Yii::app()->getBa         


        

Answer 1

You can reach your base URL by this:

Yii::$app->request->baseUrl

Answer 2

Try below code. It should work. It will return base URL name

use yii\helpers\Url;

Url::home('http') // http://HostName/ OR Url::home('https') // https://HostName/

Answer 3

Use it like this:

Yii::$app->getUrlManager()->getBaseUrl()

More information on base, canonical, home URLs: http://www.yiiframework.com/doc-2.0/yii-helpers-url.html

Answer 4

In yii 1 this code return the hostname

Yii::app()->getBaseUrl(true);

In yii2 the following

Yii::$app->getBaseUrl();

not exists as method of Yii::$app and it triggers an error with message

Calling unknown method: yii\web\Application::getBaseUrl() 

You could use Request class that encapsulates the $_SERVER

Yii::$app->request->hostInfo

Answer 5

To get base URL of application you should use yii\helpers\Url::base() method:

use yii\helpers\Url;

Url::base();         // /myapp
Url::base(true);     // http(s)://example.com/myapp - depending on current schema
Url::base('https');  // https://example.com/myapp
Url::base('http');   // http://example.com/myapp
Url::base('');       // //example.com/myapp

Url::home() should NOT be used in this case. Application::$homeUrl uses base URL by default, but it could be easily changed (for example to https://example.com/myapp/home) so you should not rely on assumption that it will always return base URL. If there is a special Url::base() method to get base URL, then use it.

Answer 6

I searched for a solution how we can do like in codeigniter, routing like e.g.

base_url()
base_url('profile')
base_url('view/12')

Only way we can do that in Yii2

<?=Url::toRoute('/profile') ?>
