session variable is not updating in ajax request

It will be better if you can show the code on what you are trying to do.

please consider follwing form:

I send above form using ajax request. I also can verify that all data reaches server. I just do following:

session(['cart_product'=>$data['productId']]);

session(['cart_quantity'=>$data['quantity']]);

above session variables simply set when I send form using traditional http because I can get them in another page. but ajax request doesnt set them.

There are couple of things that I cannot say because I cannot see your code.

So is the route that you are hitting an API route or a normal one defined in your web.php? Because if it is an API there won't be a session.

Then how do you test? Do you check your browser's network tab to make sure that the request reaches the server side and it returns successful? Also that your $data on the server contains the data?

now its working I just dont know what the problem was
