I try to redirect from one page to another and I get a Php-Notice about a missing model parameter

[Notice] Undefined variable: model
POST /home/UserDataForm

Line 145 in /srv/htdocs/framework/control/Director.php
 

I tried to add something like

$model = new Page();

but then, it outputs a blank screen.

I know, this is a Notice and almost invisible on production but it keeps me in Dev-Mode from having a clean output.

Is there another way to redirect a user from A to B?

Thank you very much in advance.

Best regards
Stefan

Director::direct() lsnt used for browser redirections.

You want redirect on a controller object or response object

Ok,

I think I found it.

I had in mind some SS 2.4 snippets

Director::redirect('SOME_URL');

but this is now:

$this->redirect('SOME_URL');

as long as I am in a Controller-Object.

Is that right?

What if you are not in a Controller object?

For example, I want to redirect after executing custom Gridfield row action?

Afaik you are always 'in a controller', meaning there's always a Controller active, based on a URL, making sure the work gets done...

You can find the current controller by using Controller::curr()
