I have already faced with this issue when i was start to create a application in Laravel.

  • in VerifyCsrfToken.php line 46
  • at VerifyCsrfToken->handle(object(Request),object(Closure)) in CsrfTokenIsValid.php line 17

First you should know about CSRF Protection. CSRF which stands for cross-site request forgeries is easy way to protect your websites.

Here i am giving you a simple scenario, When you start your application then Laravel generate a token for active user and by using this token it verify actual user and then after verify it allow you to send request to application.

So everytime when you are going to send any request by using HTML Form then you must include CSRF Token field to validate the request in middleware.

When you using Laravel Blade Form then you don't have need to include CSRF token.

You can generate CSRF Token in many ways :

  1. <input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
<input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">

OR

  1. <inputtype="hidden"name="_token"value="{{{ csrf_token() }}}"/>
<input type="hidden" name="_token" value="{{{ csrf_token() }}}" />

You can also exclude some route from CSRF protection or you can say Disable CSRF in Laravel Form some specific route.

  1. <?php
  2. namespace AppHttpMiddleware;
  3. use IlluminateFoundationHttpMiddlewareVerifyCsrfToken as BaseVerifier;
  4. class VerifyCsrfToken extends BaseVerifier
  5. {
  6. protected $except=[
  7. 'specificurl/*',
  8. ];
  9. }
<?phpnamespace AppHttpMiddleware;use IlluminateFoundationHttpMiddlewareVerifyCsrfToken as BaseVerifier;class VerifyCsrfToken extends BaseVerifier{       protected $except = [        'specificurl/*',    ];}

Sometime you get errors while sending ajax request. To solve this errors you will have to pass 'X-CSRF-TOKEN'  as a header with ajax request.
