Custom error message for Csrf validation

Hi,
how can we have custom error message displayed when the CSRF validation fails instead of the exception thrown usually?
Thanks.

I don't want to redirect back. I just want to display a simple message when the csrf request has failed.

Try/catch the SecurityException and show an error message you want.

For some reason I cannot catch the exception. I tried with the bellows but without result.

try {

...

} catch (SecurityException $e) { / } catch (\SecurityException $e) {


}

Check the CI4 source code. The classname is \CodeIgniter\Security\Exceptions\SecurityException.

I tried also that, it didn't work.

If you try to catch the exception in your controller, sorry you can't.
Because CSRF filter throws the exception. The controller is not executed yet.

Customize CSRF filter.
