The error is: TokenMismatchException in VerifyCsrfToken.php line 68:
I don't think I place any: csrf_token()
Level 27
I read the documentation but cannot quite understand it. Why would I need csrf to fix the error. Even so I try to add csrf_field(). Like this:
views/welcome.blade.php
Pick a new color for menu css:<br><br>
<form action="{{route('menu.color')}}" method="post">
{{ csrf_field() }}
<select name="cars">
<option value="red">Red</option>
<option value="blue">Blue</option>
<option value="green">Green</option>
<option value="orange">Orange</option>
</select>
<br><br>
<input type="submit" value="Submit">
</form>
</div>
The error still remains.
Level 7
did you read the documentation ? it is explained there.

First, how laravel automatically generates a CSRF "token" for each active user session?
Second I try to store token in a HTML meta tag:
by adding:
<meta name="csrf-token" content="{{ csrf_token() }}">
Yet the error still appears.

@davy_yg would you please view the free Laravel From Scratch series.
Level 27
I did finished that up once. Which episodes should I watch to get the specific error free?
Level 104
Jeez, I don't know, maybe the one titled Form Request Data and CSRF?
Level 27
I watches the video but still do not understand what I did wrong, I try do this :
views/welcome.blade.php
<div class="content">
<div class="content">
<div class="title m-b-md">
MENU CSS
</div>
Pick a new color for menu css:<br><br>
<!-- {{route('menu.color')}} -->
<!-- <form action="{{route('menu.color')}}" method="post"> -->
<form method="POST" action="/posts">
{{ csrf_field() }}
<select name="cars">
<option value="red">Red</option>
<option value="blue">Blue</option>
<option value="green">Green</option>
<option value="orange">Orange</option>
</select>
<br><br>
<input type="submit" value="Submit">
</form>
</div>
</div>
I do not understand how to imitate the video.

you say you know php
look in your controller. The first thing you do is try to use $request variable .... do you see anywhere in that function where $request gets initialised?
Level 27
You mean like this:
use Illuminate\Http\Request; // innitialize
public function getMenu()
{
$menu_color = $request->get('cars'); // using $request
I also wonder by the way: how many lesson tutorial are there exist in laravel forum? Lol. Since I see that you have taken like 760 lessons?
Is there more than that? lol.
Level 122
no, you still don't have $request
yes, there are more lessons than that
Level 27
If I don't have $request then what should I do?
I think I copy and paste someone else codes that helped me - I forget who.
Level 122
watch this https://laracasts.com/series/laravel-5-from-scratch/episodes/9
particularly from 6 minutes, and don't come back until you know what to do.

do it this way:
public function getMenu(Request $request)
{
$menu_color = $request->get('cars');
...
or use the helper function like this:
public function getMenu()
{
$menu_color = request()->get('cars');
...
