<p>So I want to return some string from <code>model</code> and <code>controller</code> but it always says undefined variable, although when I use <code> When checked with dd($ it successfully passes a)</code> and <code>dd($b)</code>. What did i do wrong? </p>
<p><code>about.blade:</code></p>
<pre class="brush:php;toolbar:false;">@extends('layout.template');
@section('homeContainer');
<p> {{ $a }} </p>
<br>
<p>{{ $b }}</p>
@endsection</pre>
<p><code>About the controller:</code></p>
<pre class="brush:php;toolbar:false;"><?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\AboutModel;
class AboutController extends Controller
{
//
public static function info(){
$a = AboutModel::info();
$b = "This data is from controller";
return view('about', compact('a', 'b'));
}
}</pre>
<p><code>About the model:</code></p>
<pre class="brush:php;toolbar:false;"><?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class AboutModel extends Model
{
use HasFactory;
public static function Info(){
$a = "This value is from model";
return $a;
}
}</pre>
<p><code>Directions: </code></p>
<pre class="brush:php;toolbar:false;"><?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\AboutController;

The controller never runs, only the callbacks in the web.php file. This means you don't have a and b variables, only a name variable
thank you for your reply! Turns out I mistakenly declared the model as a variable and a route,
For the route I changed it to
For controllers and models I remove the static and change the model declaration
Controller:
model:
