Laravel Filament Page Manager

Introduction

This package allows you to manage pages with custom templates.

Requirements

• PHP >= 8.2
• Laravel >= 11.0
• Laravel Filament >= 3.3

Installation

composer require novius/laravel-filament-page-manager

Run migrations with:

php artisan migrate

In your AdminFilamentPanelProvider add the PageManagerPlugin :

use Novius\LaravelFilamentPageManager\Filament\PageManagerPlugin;

class AdminFilamentPanelProvider extends PanelProvider
{
    public function panel(Panel $panel): Panel
    {
        return $panel
            // ...
            ->plugins([
                PageManagerPlugin::make(),
            ])
            // ...
            ;
    }
}

Route

Add to your routes/web.php file:

    \Novius\LaravelFilamentPageManager\Facades\PageManager::routes();

Configuration

Some options that you can override are available.

php artisan vendor:publish --provider="Novius\LaravelFilamentPageManager\LaravelFilamentPageManagerServiceProvider" --tag="config"

If you're overload the Page model (and so the filament resource), remember to change them in the config.

Templates

To add a template, add your custom class to templates array in the configuration file or place it under App\Pages\Templates namespace if you keep this value for autoload_templates_in.

Your class must implement Novius\LaravelFilamentPageManager\Contracts\PageTemplate.

Example :

In app/Pages/Templates/StandardTemplate.php

<?php
namespace App\Pages\Templates;

use Filament\Forms\Components\DatePicker;
use Filament\Forms\Components\RichEditor;
use Novius\LaravelFilamentPageManager\Contracts\PageTemplate;

class StandardTemplate implements PageTemplate
{
    public function key(): string
    {
        return 'standard';
    }

    public function name(): string
    {
        return trans('laravel-filament-page-manager::template.standard_template');
    }

    public function fields(): array
    {
        return [
            RichEditor::make('extras.content') // Prefix the name by `extras.` to save it in the extras fields
                ->label('Content'),
            DatePicker::make('extra.date')
                ->label('Date'),
        ];
    }
    
    public function casts() : array
    {
        return [
            'date' => 'date',        
        ];
    }

    public function view(): string
    {
        return 'templates/standard';
    }

    public function viewParameters(Request $request, Page $page): array
    {
        $settings = \App\Model\SettingsModel::instance();    
    
        return [
            'page' => $page,
            'settings' => $settings,
        ];
    }
}

You could also overload the DefaultTemplate class

<?php
namespace App\Pages\Templates;

use Filament\Forms\Components\DatePicker;
use Filament\Forms\Components\RichEditor;
use Novius\LaravelFilamentPageManager\Templates\DefaultTemplate;

class StandardTemplate extends DefaultTemplate
{
    public function fields(): array
    {
        return [
            ...parent::fields(),        

            DatePicker::make('extras.date')
                ->label('Date'),
        ];
    }
    
    public function casts() : array
    {
        return [
            'date' => 'date',        
        ];
    }

    public function view(): string
    {
        return 'templates/standard';
    }
}

Fields

To use the specific template fields :

$page = \Novius\LaravelFilamentPageManager\Models\Page::where('template', 'standard')->first();

$content = $page->extras['content'];

// Date will be a Carbon instance, thanks to the cast
$date = $page->extras['date'];

View

In the template view, use the documentation of laravel-meta to implement meta tags.

The page manager automatically calls the CurrentModel::setModel() method for you, with the current page displayed.

Special Pages

The page manager came with three special pages:

• Home page
• Page for 404 error

You could remove those special pages if you don't need them.

For the 404 pages to work, you must add middleware HandleSpecialPages to the Middleware group Web. In your provider/app.php file :

use Illuminate\Routing\Middleware\SubstituteBindings;
use Novius\LaravelFilamentPageManager\Http\Middleware\HandleSpecialPages;

return Application::configure(basePath: dirname(__DIR__))
    //...
    ->withMiddleware(function (Middleware $middleware) {
        //...
        $middleware->web(remove: [
            SubstituteBindings::class,
        ]);
        $middleware->web(append: [
            HandleSpecialPages::class,
            SubstituteBindings::class,
        ]);
        //...
    })
    //...
    })->create();

Custom Special page

You can create your owned special page. Add your custom class to special array in the configuration file or place it under App\Pages\Special namespace if you keep this value for autoload_special_in.

Here are two examples.

One for a contact page:

<?php
namespace App\Pages\Special;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use Novius\LaravelFilamentPageManager\Contracts\PageTemplate;
use Novius\LaravelFilamentPageManager\Contracts\Special;
use Novius\LaravelFilamentPageManager\Facades\PageManager;

class Contact implements Special
{
    public function key(): string
    {
        return 'contact';
    }

    public function name(): string
    {
        return 'Contact';
    }

    public function icon(): ?string
    {
        // you can return null if you d'ont want icon in the filament interface
        return 'heroicon-o-paper-airplane';
    }

    public function pageSlug(): ?string
    {
        // return null, let the user define is owned slug for this page
        return null;
    }

    public function template(): ?PageTemplate
    {
        // return null, let the user define is owned template for this page
        return null;
    }

    public function statusCode(): ?int
    {
        // return null, your page has a 200 status code
        return null;
    }

    public function routes(): void
    {
        // do nothing, your page will be handled by the main page manager route 
    }
}

Another for a page displaying a product :

<?php
namespace App\Pages\Special;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use Novius\LaravelFilamentPageManager\Contracts\Special;
use Novius\LaravelFilamentPageManager\Facades\PageManager;

class Product implements Special
{
    public function key(): string
    {
        return 'product';
    }

    public function name(): string
    {
        return 'Product';
    }

    public function icon(): ?string
    {
        return null;
    }

    public function pageSlug(): ?string
    {
        // return null, let the user define is owned slug for this page
        return null;
    }

    public function template(): ?PageTemplate
    {
        return \App\Pages\Templates\ProductTemplate::class;
    }

    public function statusCode(): ?int
    {
        // return null, your page has a 200 status code
        return null;
    }

    public function routes(): void
    {
        PageManager::route(
            $this,
            '{product}',
            static function (Request $request, Product $product) {
                return PageManager::render($request);
            },
            'page-manager.product'
        );
    }
}

Next in the method viewParameters of your template, you could do that:

use Novius\LaravelFilamentPageManager\Contracts\PageTemplate;

class ProductTemplate implements PageTemplate
{
    // ...
    public function viewParameters(Request $request, Page $page): array
    {
        $product = Route::getCurrentRoute()?->parameter('product');
        CurrentModel::setModel($product);

        return [
            'page' => $page,
            'product' => $product,
        ];
    }
}

Guards

Si vous voulez protéger certaines pages derrière des guards, il suffit d'ajouter dans la config laravel-filament-page-manager.php:

    // If you want certain pages to be protected by a Guard, indicate the list of guards you want to make available (must be in `config('auth.guards')` keys)
    'guards' => [
        'myquard',
    ],

Facade and Helpers

use Novius\LaravelFilamentPageManager\Facades\PageManager;
use Novius\LaravelFilamentPageManager\Models\Page;
use Novius\LaravelFilamentPageManager\SpecialPages\Page404;

PageManager::templates();  // return Collection<string, PageTemplate>
PageManager::template('default'); // return the PageTemplate with the 'default' key
PageManager::specialPages();  // return Collection<string, Special>
PageManager::special('homepage'); // return the Special with the 'homepage' key
PageManager::routes(); // Use it in your `routes/web.php` file

Page::getHomePage('en'); // return the Page defined as special Homepage in locale 'en'
Page::getHomePage(); // return the Page defined as special Homepage in the current locale
Page::getSpecialPage('404', 'en'); // return the Page defined as special Page404 in locale 'en'
Page::getSpecialPage('404'); // return the Page defined as special Page404 in the current locale
Page::getSpecialPage(Page404::class); // return the Page defined as special Page404 in the current locale
Page::getSpecialPage(new Page404()); // return the Page defined as special Page404 in the current locale
