Answer 1

you need to add {{csrf_field()}} inside the form. it will create a csrf token, which is needed to submit a form

Answer 2

You need to add this {{ csrf_field() }} between your form tags.Read here for more information https://laravel.com/docs/5.4/csrf

Answer 3

There are many options to solve this problem.
1) You can take hidden input field for token inside your form like:
<input type="hidden" name="_token" value="{{ csrf_token() }}" />
2) Add following code before the closing tag of your form:
{{ Form::token() }}
3) Or use laravel form syntax to avoid token mismatch problem like below.
{{ Form::open(array('url' => 'foo/bar')) }}
//
{{ Form::close() }}
4) Or in the html form structure you can also use csrf field like below.
<form method="POST" action="/profile">
{{ csrf_field() }}
...
</form>
5) Or lastly.
<form method="POST" action="/profile">
{!! csrf_field() !!}
...
</form>
This will definately work for you.
Thanks
