Generate a Secure Random String in PHP php Copy code

if (!empty($_POST['phone_number'])) {
  die("Bot detected");
}

Why it works: Bots usually fill every field, including hidden ones. Real users never see it.

Use Vite to serve and build your assets:

   npm run dev

   php artisan migrate

Run the following command to create the Post model and migration file:

   <button class="btn btn-primary custom-class" id="unique-btn">Submit</button>

Add the directive in AppServiceProvider:

Enforce HTTPS by updating the .env file:

   APP_URL=https://example.com

   namespace App\Http\Controllers;

   use App\Models\Post;

   class PostController extends Controller
   {
       public function index()
       {
           $posts = Post::paginate(10); // Default pagination
           return response()->json($posts);
       }
   }

Modify the response structure to include metadata and links:

Use PHPUnit to test job behavior under concurrent scenarios:

   public function testJobHandlesConcurrency()
   {
       for ($i = 0; $i < 5; $i++) {
           ProcessOrderJob::dispatch($orderId);
       }

       $this->assertDatabaseHas('orders', ['id' => $orderId, 'status' => 'processed']);
   }

Use the store() method to save files in Laravel’s storage directory:

   public function store(Request $request)
   {
       $path = $request->file('file')->store('uploads');
       return response()->json(['path' => $path]);
   }

Install Laravel Debugbar to visualize queries and their execution time:

   composer require barryvdh/laravel-debugbar --dev

• Confirm it’s assigned to the route.
• Ensure there are no typos in the middleware alias or class name.

Middleware executes in the order defined in Kernel.php. Conflicts can occur if one middleware depends on another but runs earlier.

   $posts = Post::with(['comments' => function ($query) {
       $query->where('approved', true);
   }])->get();

• Use eager loading to optimize performance with nested relationships.
• Leverage custom pivot models for complex many-to-many relationships with additional fields.
• Employ polymorphic relationships for reusable relationships across multiple models.
• Query and filter nested relationships to handle complex data requirements efficiently.

   use Illuminate\Support\Facades\DB;

   DB::listen(function ($query) {
       logger($query->sql, $query->bindings);
   });

Check your logs for repeated queries related to relationships.

Heroku's DATABASE_URL uses the older postgres:// scheme, which isn't compatible with the latest SQLAlchemy requirements. Starting with SQLAlchemy 1.4, postgres:// is considered deprecated and no longer supported. The explicit postgresql+psycopg2:// scheme is required.

Without this replacement, SQLAlchemy might throw an error like:

This script will ensure that both the posts and their associated media files are removed from the WordPress database and the filesystem.

• Http::withToken(): Adds a Bearer Token for authorization in the request headers.

Most modern APIs return data in JSON format. Laravel simplifies handling JSON responses by providing a json() method.

use Laravel\Sanctum\HasApiTokens;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Customer extends Authenticatable
{
    use HasApiTokens;

    protected $fillable = ['name', 'email'];

    // Define the relationship with tokens
    public function tokens()
    {
        return $this->morphMany(\Laravel\Sanctum\PersonalAccessToken::class, 'tokenable');
    }
}

The HasApiTokens trait adds the ability to issue tokens to the Customer model.

• Emit without Reloading the Whole Page: Use Livewire emit to target specific parts of the application instead of refreshing the entire page.
• Combine PHP and JS Events: Use $emit in PHP and Livewire.emit in JS to create seamless interactions between backend and frontend.
• Browser Event Dispatching: Use dispatchBrowserEvent in PHP to trigger JS behavior without needing heavy front-end frameworks.

This cheat sheet provides a quick reference for common Livewire interactions, helping you efficiently bridge PHP and JavaScript in your Livewire applications.
