When I pass my custom helper function as a variable to Laravel Blade, the bug occurs when I click a link to a new page. The error will read the variable was not found. There are a total of 6 navigation links, the first variable pass to the nav link is read by Laravel blade, the other are not. I’ll provide example code below.

Utilities/Helper class example – my custom helper function

<?php

namespace AppUtilities;

class Helper
{
  public static function activePage(string $pageUrl): string
  {
    $requestUri = $_SERVER['REQUEST_RUI'];
    
    return $requestUri === $pageUrl ? "color=var(--sky)" : "color=var(--mud)";   
  }
}

Controller/Home Action example

<?php

namespace AppHttpControllers;

use AppHttpControllersBaseController;
use AppUtilitiesHelper;
use IlluminateViewView;

class Home extends BaseController
{

  public function __construct(
   private Helper $helper,  
  ){}

  public function index(): View
  {
    reutrn view('home', [
      'helper' => $this->helper::class,
    ]);
  }
}

Laravel Blade Template home page example

<li class="nav-links">        
  <a href="{{ url('/') }}"         style="{{ $helper::activePage('/') }}">Home</a>
  <a href="{{ url('/services') }}" style="{{ $helper::activePage('/services') }}">Services</a>
  <a href="{{ url('/clients') }}"  style="{{ $helper::activePage('/clients') }}">Clients</a>
  <a href="{{ url('/about') }}"    style="{{ $helper::activePage('/about') }}">About</a>
  <a href="{{ url('/blog') }}"     style="{{ $helper::activePage('/blog') }}">Blog</a>
  <a href="{{ url('/contact') }}"  style="{{ $helper::activePage('/contact') }}" class="contact-link">Contact</a>
</li>

After reading the code, is there anything you think would cause an error to occur?
