Redirect attribute

---

1Presentation

This attribute can be used to force a redirection, systematically preventing access to a controller or action. This can be useful during debugging, or to temporarily disable access to a portion of code.

---

2Parameters

The attribute offers several parameters:

• $url: (string) Redirection URL.
• $var: (string) Name of the template variable containing the redirect URL.

---

3Priority

To define the URL to which the user will be redirected, the attribute applies the following order of priority:

1. If the $url parameter is defined, it is used.
2. If the $var parameter is defined, and it contains the name of an existing, non-empty template variable, its content is used.
3. If the etc/temma.php file contains an x-security extended configuration, and this contains a redirect key, its content is used.

If no redirect URL is found, a 403 error is returned.

---

4Configuration

To ensure that all Redirect attributes redirect to the same URL, simply define it in the etc/temma.php file:

[
    'x-security' => [
        'redirect' => '/temporaryHomepage'
    ]
]

To ensure that the redirect URL is the same for the Auth, Method, Referer and Redirect attributes, simply define the redirect key in the x-security extended configuration in the etc/temma.php file:

[
    'x-security' => [
        'redirect' => '/login'
    ]
]

5Examples

use \Temma\Attributes\Redirect as TµRedirect;

// redirects all accesses to this controller
// to the URL defined in the 'etc/temma.php' file
#[TµRedirect]
class Login extends \Temma\Web\Controller {
    // ...
}

use \Temma\Attributes\Redirect as TµRedirect;

class Homepage extends \Temma\Web\Controller {
    // redirects to new home page
    #[TµRedirect('/newHomepage')]
    public function oldHome() { }
}

use \Temma\Attributes\Redirect as TµRedirect;

class Homepage extends \Temma\Web\Controller {
    // controller initialization: definition of
    // the 'homeRedir' template variable
    public function __wakeup() {
        $this['homeRedir'] = '/otherHomepage';
    }

    // redirection to the URL defined in the
    // 'homeRedir' template variable
    #[TµRedirect(var: 'homeRedir')]
    public function action1() {
        // ...
    }
}
