Hi

So I have a custom taxonomy: **maintenance\_package**

I am using the following blade template which is working fine…

**taxonomy-maintenance\_package.blade.php**

For bug fixing this issue, it just has this code in it…

```
@extends('layouts.app')

@section('content')
    {{ $testing_controller }}
@endsection
```

What I cant seem to do is get a controller working with the template.

My assumption was that it would be named this…

**TaxonomyMaintenancePackage.php**

And its contents would be this…

```
<?php

namespace App\Controllers;

use Sober\Controller\Controller;

class TaxonomyMaintenancePackage extends Controller
{
    public function TestingController()
    {
        return 'Hello World';
    }
}
```

\*\* _I have also tried it as a static function which also doesn’t work_

The error I am getting is…

```
Notice: Undefined variable: testing_controller in /Path/To/My/Cache...
```

I have tried these class/controller file naming structures with no joy…

- Taxonomy\_Maintenance\_Package
- TaxonomyMaintenance\_Package
- MaintenancePackage

**Additional info…**

Im using Sage v9.0.9

The taxonomy is created using the plugin below and uses underscores between its naming of the slug which I thought might be an issue maybe? possibly?

> **[Custom Post Type UI](https://wordpress.org/plugins/custom-post-type-ui/)**
>
> Admin UI for creating custom post types and custom taxonomies for WordPress

Any help would be gratefully received… :slight_smile:

You can use a debug plugin like Query Monitor or Debug Bar to show a list of all attempted template paths for a taxonomy:

> **[Query Monitor](https://wordpress.org/plugins/query-monitor/)**

> Query Monitor is the developer tools panel for WordPress.
