Middleware

Middleware sits between a request and a response, allowing you to filter and manipulate HTTP requests. Pollora uses standard Laravel middleware and adds WordPress-specific middleware for seamless integration.

For general Laravel middleware concepts, see the official Laravel documentation.

Pollora Middleware

Pollora includes four WordPress-specific middleware that are automatically applied to WordPress routes:

WordPressBindings

Injects WordPress objects (WP_Post, WP_Query, WP_User, etc.) into route closures and controller methods based on type hints.

// The $post parameter is automatically resolved from the current WordPress context
Route::wp('single', function (WP_Post $post) {
    return view('post', compact('post'));
});

WordPressHeaders

Manages HTTP headers for WordPress responses:

• Adds X-Powered-By: Pollora header
• Controls cache headers
• Removes unnecessary WordPress headers for unauthenticated requests

WordPressBodyClass

Adds route-based CSS classes to the WordPress body_class output, allowing you to style pages based on the matched route condition.

WordPressShutdown

Ensures WordPress shutdown hooks (shutdown action, output buffer flushing) are properly executed after the Laravel response is sent.

Creating Custom Middleware

Use Artisan to generate a new middleware:

php artisan make:middleware CheckWordPressCapability

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class CheckWordPressCapability
{
    public function handle(Request $request, Closure $next, string $capability = 'edit_posts')
    {
        if (! current_user_can($capability)) {
            abort(403);
        }

        return $next($request);
    }
}

Applying Middleware to WordPress Routes

Route::wp('page', fn () => view('page'))
    ->middleware('auth');

Route::wp('single', fn () => view('post'))
    ->middleware(CheckWordPressCapability::class . ':publish_posts');

Middleware Groups

You can group WordPress routes with shared middleware:

Route::middleware(['auth', 'verified'])->group(function () {
    Route::wp('page', fn () => view('page'));
    Route::wp('single', fn () => view('post'));
});
