Two forms on one website, each with two times {{ csrf_field() }}

If you just have an HTML/blade only form (so no javascript), this should work for multiple forms automatically. The CSRF-token would work just fine for both forms. You can use 100 forms using the same token if you like.

Can you share how you created your form in your view?

Sorry, I forgot how to post a code snippet. The forum completely changed the code I posted above, I don't remember what it was like to put a blade-code in without it being changed.

I only use Javascript to change the attributes of the HTML code, but no AJAX or something like that.

Should be fine with two forms. Either can be submitted. After that form is processed, you should re-render the view by returning a redirect back to the original page.

Thank you. It works. But coming back with the following I cannot access the variable 'success':

return redirect()->back()->with( 'success', 'It works.');

// Blade:
@section('system_message')
    @if(session()->has('error'))
        <div class="bgerror colorgreyd pad15px">
            {{$error}}
        </div>
    @elseif(session()->has('success'))
        <div class="bgsuccess colorgreyd pad15px">
            {{$success}}
        </div>
    @endif
@endsection

I think session always has $error but it is null if there is no error

Change your elseif to a seperate if

@section('system_message')
    @if(session()->has('error'))
        <div class="bgerror colorgreyd pad15px">
            {{$error}}
        </div>
    @endif

    @if(session()->has('success'))
        <div class="bgsuccess colorgreyd pad15px">
            {{$success}}
        </div>
    @endif
@endsection

Thank you, but the variable seems to be unknown:

ErrorException (E_ERROR)
Undefined variable: success ...
Previous exceptions
Undefined variable: success (0)

Return back means going back to the previous step. Does that mean that the success variable doesn't yet exist?

I found a workaround through the Session helper

// Controller
session( [ 'success' => 'It works.' ] );
return redirect()->back();

// Blade
@section('system_message')
    @if(session()->has('error'))
        <div class="bgerror colorgreyd pad15px">
            {{$error}}
        </div>
    @endif
    @if(session()->has('success'))
        <div class="bgsuccess colorgreyd pad15px">
            {{session()->get('success')}} 
            {{session()->forget('success')}}
        </div>
    @endif
@endsection

This line echos whatever comes back from the forget function

{{session()->forget('success')}}

If you want success to only appear once, use instead the flash() function.

https://laravel.com/docs/8.x/session#flash-data

Also look at named error bags so that the forms get their own error variables.

Thank you, it works fine
