Hi JackJones,

thanks for your answer :) but I know how to set session and validate them. Thats not the problem. Perhaps I wasnt explicit enough.

My problem is how can I change the actual session variable by a clickable link>

So I need that user can click on a link than the session variable is change from 4 to (e.g.) 6.

For security reasons I would validate it afterwards by validation.

Thanks and best Julia

I assumed because the channel was set to Laravel that the issue was Laravel

If I understand you correctly, and you don't want the user to leave the page, you would need to send an ajax request to a Controller when the number is pressed, which leads to a Controller that updates the session

Yes right i am using Laravel :)

Yes but it also would be possible to refresh the page, if a link is pressed.

But how can i change the session by a link or by pressing a number? It wouldnt be a problem to reload the page so AJAX would be fine but isnt necessary..

Thanks in advance :)

You would load a very simple Controller, validate the request (the id variable or whatever you decide to call it, update the session and return back();

$this->validate($request, [
        'number' => 'required|integer|in:' . implode(',', 'your valid numbers')
    ]);

session()->put('number', $request->input('number'));

return back();

Thanks a lot, you are my hero ;) I think this is the solution.

One more question:

If i create the Controller like above. How can I call it. Because there is no view rendered and the controller should be accsessable from different pages with different view.

Literally any way you like

Route::get('/change-number', [ 'as' => 'change-number',
                        'uses' => 'ChangeNumberController@update'
                        ]);

{!! route('change-number') !!}

You could do it with wildcards which would also be an option, but this method is the most basic

OK it works! Thanks again hundred times! And have a nice evening :)

Ah and with the validation function there is no chance to manipulate this thing, right?
