How CsrfToken works
I am having a continuous issue with csrf token. When i post my from i always get this annoying token mismatch exception. How actually these token works and how can i overcome this issue. This is happening on the form post where user is already logged in and updates his profile information.
Level 3
the value doesn't rendered. you need to print this function:
csrf_token()
Level 41
If you are using the form builder
{!! Form::open() !!}
{!! Form::close() !!}
This will handle creating CSRF token for you, if not, you need to add a hidden input to your form with the value of the token that laravel generates.
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
Level 34
Yes i am using form builder , and it handles that ( i can see token in the page source ) but still it says token mismatch exception
Level 41
Are you posting via AJAX? Maybe post some code.
Level 34
I tried all of these: 1 ) Manually adding hidden field of token. 2 ) Adding token field as a meta tag in my layout page But still it shows same error..
Level 34
No not through ajax.. simple form submission ,
{!! Form::open(['method'=>'POST','url'=>'wizard/js/personal','novalidate'=>'novalidate','id'=>'jsPersonal-form','class'=>'ali-form']) !!}
And it creates token automatically , but when i hit submit button this error is thrown

Open your browser's developer tools window and navigate to the Network tab. When you press submit, check the POST entry and take a look at the params of the POST. This will show you what data was sent, if you do not see a _token, it wasn't sent.
Once you confirm that's there, we'll go from there.
Level 34
Ok i am going to do what you told me
Level 34
There is _token present in form data and exactly set to the value that i can view while inspecting the source of page, status code is 500
Remote Address:[::1]:8000
Request URL:http://localhost:8000/wizard/js/personal
Request Method:POST
Status Code:500 Internal Server Error
_token:OVEFrXK9gZuWsJYP8OXFRWu54jR2FMUVKKs9KsSz
Level 34
@bashy This is extremely strange and annoying.. :-(
Level 65
You could be doing something not related directly to CSRF token. Can you show the code used in the form? Have you got a live dev link?
Level 23
@AliMalik what is your session lifetime set to in your session.php config file? Could be that your session lifetime cycle is expiring. If you session expires the CSRF token will mismatch. In AngularJS fo example you can look for this and redirect to login.
Example, if you set the value below to 1 then every minute it will expire.
/*
|--------------------------------------------------------------------------
| Session Lifetime
|--------------------------------------------------------------------------
|
| Here you may specify the number of minutes that you wish the session
| to be allowed to remain idle before it expires. If you want them
| to immediately expire on the browser closing, set that option.
|
*/
'lifetime' => 120,

This is my form that gives me mismatch error upon submission
{!! Form::open(['method'=>'POST','url'=>'wizard/js/personal','novalidate'=>'novalidate','id'=>'jsPersonal-form','class'=>'ali-form']) !!}

Why not verify your code is working and turn of CSRF.
Go to App\Http\Kernel.php and comment out the CSRF service...
<?php namespace App\Http;
use Illuminate\Foundation\Http\Kernel as HttpKernel;
class Kernel extends HttpKernel {
/**
* The application's global HTTP middleware stack.
*
* @var array
*/
protected $middleware = [
'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
'Illuminate\Cookie\Middleware\EncryptCookies',
'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
'Illuminate\Session\Middleware\StartSession',
'Illuminate\View\Middleware\ShareErrorsFromSession',
'App\Http\Middleware\VerifyCsrfToken',
```
and give your form a go.
Level 34
@jimmck By commenting verifyCsrfToken Form posted successfully
Level 34
Does It mean issue is with sessions or csrf.. ?
Level 65
What session driver are you using? Don't think you posted it above did you?
Level 13
@ AliMalik So after you turned off middleware your form post worked? I am in US so we got a time diff. If yes you are either not sending proper token or getting from your session? Can you add _token as hidden form field? Here is a quick way I use for testing/ not prod. I have a Get call to grab a new token.
\Route::get('token', function () {
return csrf_token();
});
Call this URL and put the token in your hidden field and POST your form. Of course turn on middleware. I send JSON data structs to a controller over POST so I just add token each time.
//fyi("inside call...");
// how do we check the url is correct? timeout causes problems.
// the busy flag needs to be static for the class.
// make sure if callData is an object we make it an empty object.
// we do this so we can add _token to it.
if (callData == "") {
callData = {};
}
this.busy = true;
callData['_token'] = this.csrf_token;
fyi('Post token [' + callData['_token'] + ']');
$.myPost(url, callData, this, this.handlePost, this.postError, this.timeout, this.async);
Level 34
@bashy This is my session driver:
'driver' => env('SESSION_DRIVER', 'file'),
Level 34
@jimmck Yes i manually added the token as a hidden field in my form and posted , but this token is same as created by form builder.
Level 65
Must be something up with your session data, that line you pasted above doesn't show it 100%, do you have SESSION_DRIVER environment var set?
Level 34
This is my sessions file
return [
'driver' => env('SESSION_DRIVER', 'file'),
'lifetime' => 120,
'expire_on_close' => false,
'encrypt' => false,
'files' => storage_path().'/framework/sessions',
'connection' => null,
'table' => 'sessions',
'lottery' => [2, 100],
'cookie' => 'laravel_session',
'path' => '/',
'domain' => null,
'secure' => false,
];
And yes env variable is set to file
SESSION_DRIVER=file
Level 65
Have you checked if it's saving them okay? Does authentication work fine?
Level 34
Yes Authentication is working fine on all other pages , i am stuck on this specific form. Also by checking network tab of dev tools as you guided earlier i see that it is maintaining sessions and csrf token both

Are you sure it's being sent by JS? I've never had a problem with CSRF tokens...
Level 34
Me to bro just this specific case dnt know why
Level 1
you can try :
<form action="{!! url('your/page') !!}" method="POST">
<input type="hidden" name="_token" value="{!! csrf_token() !!}">
</form>
Level 34
After so much of testing and tries to solve it, i cannot solve the issue, but when i switched from laravel dev server to my EasyPhp local server it stopped throwing me those annoying mismatch errors. Any note on that..??
