redirect back to post route, i get methodnotallowed exception

@yigitozmen Any redirects are performed using GET. Your forms should be rendered as GET methods, and the data submitted as a POST request. When you’ve persisted the form submission’s data, you should then redirect to the next “step” using GET too.

For example:

Route::get('step-1', 'StepOneController@showForm');
Route::post('step-1', 'StepOneController@handle');

Route::get('step-2', 'StepTwoController@showForm');
Route::post('step-2', 'StepTwoController@handle');

class StepOneController extends Controller
{
    public function showForm()
    {
        return view('forms.step-1');
    }

    public function handle(Request $request)
    {
        // Validate data
        // Persist data ready for displaying step 2

        return redirect('step-2');
    }
}

This way, if a user submits incorrect data for any step, you can just redirect them back and present the form again.

@martinbean thank you, what are you suggesting for "persist or transport data" between page without any querystring?

I am thinking session right now. Is there any best practise to do this? Thank you.

@yigitozmen If you have a lot of data, you could save it to a database table, and then store the ID of that in your session. Means a user would be able to save and come back to the process later if that’s applicable to your use case.

@martinbean impossible because the company doesnt want to use database, because i will send the data via api layer. i think session is the way for me

@yigitozmen There’s nothing stopping you storing it in a database in your application, and then retrieving and sending it via the API when the user completes the form.

@martinbean they are not providing db system for this application? its not allowed using any database. api is external...

by the way, cant tick correct for your post, why i dont know. im using chrome in linux. i will tick it in win later

@yigitozmen Ah. Seems to be a bug! https://laracasts.com/discuss/channels/site-improvements/bug-thread-cant-be-resolved

persist between steps with Session variables?

After step1 form validation, you can save the values in the session, then redirect to step 2 with a Get.

In the controller for step 2, do the same

In the controller for step 3, when the form is posted, gather all the data from the session for steps 1 and 2, combine with data from step3 and send to the API.

In step 1, check for the session variables incase someone is coming back from step2 so that you can restore their original choices.

i am facing the same problem, if you post a data from a form and your second form is dynamic and it forms on the basis of first form submitted data , in this situation when you submit the second form it shows you the method not allowed exception?
