Laravel catch TokenMismatchException

You can handle TokenMismatchException Exception in App\Exceptions\Handler.php

<?php namespace App\Exceptions;use Exception;use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;use Illuminate\Session\TokenMismatchException;class Handler extends ExceptionHandler {    /**     * A list of the exception types that should not be reported.     *     * @var array     */    protected $dontReport = [        'Symfony\Component\HttpKernel\Exception\HttpException'    ];    /**     * Report or log an exception.     *     * This is a great spot to send exceptions to Sentry, Bugsnag, etc.     *     * @param  \Exception  $e     * @return void     */    public function report(Exception $e)    {        return parent::report($e);    }    /**     * Render an exception into an HTTP response.     *     * @param  \Illuminate\Http\Request  $request     * @param  \Exception  $e     * @return \Illuminate\Http\Response     */    public function render($request, Exception $e)    {        if ($e instanceof TokenMismatchException){            // Redirect to a form. Here is an example of how I handle mine            return redirect($request->fullUrl())->with('csrf_error',"Oops! Seems you couldn't submit form for a long time. Please try again.");        }        return parent::render($request, $e);    }}

A Better Laravel 5 Solution

in App\Exceptions\Handler.php
Return the user to the form with a new valid CSRF token, so they can just resubmit the form without filling the form again.

public function render($request, Exception $e)    {         if($e instanceof \Illuminate\Session\TokenMismatchException){              return redirect()                  ->back()                  ->withInput($request->except('_token'))                  ->withMessage('Your explanation message depending on how much you want to dumb it down, lol!');        }        return parent::render($request, $e);    }

I also really like this idea:

Instead of trying to catch the exception just redirect the user back to the same page and make him/her repeat the action again.

Use this code in the App\Http\Middleware\VerifyCsrfToken.php

<?phpnamespace App\Http\Middleware;use Closure;use Redirect;use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;class VerifyCsrfToken extends BaseVerifier{    /**     * The URIs that should be excluded from CSRF verification.     *     * @var array     */    protected $except = [        //    ];    public function handle( $request, Closure $next )    {        if (            $this->isReading($request) ||            $this->runningUnitTests() ||            $this->shouldPassThrough($request) ||            $this->tokensMatch($request)        ) {            return $this->addCookieToResponse($request, $next($request));        }        // redirect the user back to the last page and show error        return Redirect::back()->withError('Sorry, we could not verify your request. Please try again.');    }}
