{{ csrf_field() }} added tokenmismatch exception

@muazzamazaz can you supply the method you are posting to? does it have a redirect to another page with a form on it?

@automica

<form class="form-horizontal" role="form" method="POST" action="{{ url('/provider/register') }}">

may be usefull..

may be usefull

@muazzamazaz can you show the controller method that corresponds to /provider/register route?

@muazzamazaz

just add this

<form class="form-horizontal" role="form" method="POST" action="{{ url('/provider/register') }}">
@csrf

</form>

@jeevamugunthan @muazzamazaz said he had CSRF field as

{{ csrf_field() }} 

which is the same doing

@csrf

@jeevamugunthan making assumptions about the version of Laravel.

Are sessions working ok? Can you login and stay logged in?

@snapey Laravel 5.3

Signup/ Signin both have same error

@muazzamazaz is it not working just on your production environment or are you having the same issue locally as well as remotely?

@automica the issue is locally as its a code given to me

Are you running on apache?

Open network tools in the browser. Check for cookies. You should have a cookie that looks like your_app_name_session

The csrf issue is a side effect of having no sessions

@snapey yes there is no cookie for this app name, what to do?

as a quick test, use php artisan serve then visit the url it gives you and see if you have the same issue

@snapey same issue for url given http://127.0.0.1:8000/

There is an issue sometimes seen where if any content is output before the request terminates then it can stop cookies being sent to the client. As far as I know, this only affects apache. Your test with artisan serve suggests it might not be this problem.

Anyway, it might be worth checking. This is issue is caused by either;

• having some characters before <?php in any php file
• using ?> at the end of a php file and then having some trailing data like a blank line.

I would have a quick look. Check your routes file(s), then service providers, then config files.

You are looking for anything - even a blank line, before <?php or if the previous developer has used ?> in any .php file (if so, delete it)
