Create Url, Links and Redirections in Yii framework

This post will be a reference on how deal with urls, links and browser redirects in Yii Framework. It will guide you on how to use different built-in functions in Yii like createUrl(), createAbsoluteUrl(), CHtml::link(), redirect().

Create URL

$url = Yii::app()->createUrl('site/index');
Result: index.php?r=site/index

You will obtain this format of URL if you're not using the URL Manager to make your links more user-friendly.

$url = Yii::app()->createUrl('site/index', array('id'=>100));

Result: index.php?r=site/index&id=100

Create URL from Controller

Yii::app()->controller->createUrl("index", array("id"=>100));

Result: index.php?r=site/index&id=100
You will obtain this result if your current controller is "SiteController".
If you are in a controller you can simply write

$this->createUrl('index',array('id'=>100));

Create absolute URL:

In order to create an absolute path url you need to use createAbsoluteUrl() function:

Yii::app()->createAbsoluteUrl('site/index',array('id'=>100));

Result: http:⁄⁄yourdomain.tld⁄index.php?r=site⁄index&id=100

Create Link

You can use the CHTML helper to quickly create an anchor in HTML:

echo CHtml::link('text', array('site/index', 'id'=>100));

Result: <a href="/ABC/index.php?r=site/index&amp;id=100″>text</a>

Redirect Browser

$this->redirect(array('site/index','id'=>100));

It will redirect the browser to index.php?r=site/index&id=100
