How to set urls from controller action in cakephp?

@elmo.conroy 

In CakePHP, you can set URLs from controller actions using the Router class. The Router class provides methods to generate URLs based on the current routing rules.

Here's an example of how you can set a URL in a controller action:

1
2
3
4
5
6
7
8
9

class ExampleController extends AppController {
    public function index() {
        // Generate the URL for the index action
        $url = Router::url(['controller' => 'Example', 'action' => 'index']);

        // Pass the URL to the view
        $this->set(compact('url'));
    }
}

In the above example, the Router::url() method generates the URL for the index action of the Example controller. The URL is then passed to the view using the set() method, which makes it available for use in the view.

You can also pass parameters to the Router::url() method, for example:

1

$url = Router::url(['controller' => 'Example', 'action' => 'view', $id]);

In this case, the $id parameter is passed to the Router::url() method, which will be included in the generated URL.

You can find more information on using the Router class to generate URLs in the CakePHP documentation.
