Hi,
Does anyone know how to solve this? I have tried all kinds of things, and searched, and cannot solve this, so posting here in the hope the community knows.
The component was made with Artisan. The component works fine if in the head folder. I have other components in the same subfolder and those work fine (but they don't call code like this, but pass variable directly for example (:variable=$variable). I have tried all kinds of possible solution, remade it, searched, asked the AI, restarded server, cleared caches, tried different namespaces and folders, etc. I have tried dd, different types of code. It just looks like when moving to subfolder it loses the connection with the component class, like the two are not aware of each other anymore maybe.
I want to have things like dynamic page headers based on the section where at. So I can reuse code and not have so many different templates, for each section.
Undefined variable $headerTitle
It will still load the template and load the static text. Just it can't process the $headerTitle variable for a reason I cannot figure out.
<x-app-layout>
<x-slot name="header" id="dashboard-records-header">
<x-forms.records.header-records />
</x-slot>
// code
namespace App\View\Components\Forms\Records;
use Closure;
use Illuminate\View\Component;
use Illuminate\Contracts\View\View;
use Illuminate\Support\Facades\Route;
class HeaderRecords extends Component
{
public $headerTitle;
public function __construct()
{
$this->headerTitle = $this->generateTitle();
}
private function generateTitle(): string
{
$segments = explode('.', Route::currentRouteName());
if (isset($segments[1])) {
return ucfirst($segments[1]);
} else {
return 'Records List';
}
}
/**
* Get the view / contents that represent the component.
*/
public function render(): View
{
return view('components.forms.records.header-records');
}
}
<div>
Hello Header Records Heading
{{ $headerTitle }}
</div>
You should move the code that generates the title inside the render method and pass the variable to the view.
public function render(): View
{
$headerTitle = $this->generateTitle();
return view('components.forms.records.header-records', compact('headerTitle'));
}
Thank you. I tried that solution, but I still get the same error unfortunately.
I found a temporary solution by enclosing the code part in @php tags in the Blade template, instead of the Component Class, however not my preferred solution for various reasons. Than I ran into the same issue for another Component template and class.
What I can find in the documentation is this: https://laravel.com/docs/11.x/blade#component-methods
I copied the method and Component template code, and then I get the same type of error: Undefined variable $isSelected
Wonder what I am overlooking.
Did you find a more permanent solution?
I thnk the problem your having is because your blade syntax is:
<x-forms.records.header-records /> it matches on the view side of things but not the component path. Generally with components the class path matches the view path or mainly the path that you are entering in blade.
So Laravel will be looking for the class component in Views/Components/Forms/Records/HeaderRecords.php and if it cant find it, it will then assume anonymous so look for the blade file alone and then if it cant find that then it will throw exception.
If you match your blade syntax to where the class is and then load the view that you want then the $headerTitle should be defined. It's not defined for before because its not running through the class and just treating it like an anonymous component
