## What it does

The rule applies to `**/*.php` files. It recommends moving complex business logic into services or models and putting validation in Form Request classes. For database work, it favors Eloquent with eager-loaded relationships; for data transformations, it points to Laravel Collections rather than manual array handling.

It also covers mass-assignment protection with `$fillable` or `$guarded`, chunking large datasets, and caching expensive queries. Database queries inside Blade templates are discouraged. Without eager loading, accessing a relationship for each record can trigger the N+1 problem.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/laravel.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/laravel.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/laravel.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/laravel.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/laravel.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/sanjeed5/awesome-cursor-rules-mdc/tree/HEAD/rules-mdc/laravel.mdc

## When to use it
- move order logic out of a controller into a service
- put request validation in a Form Request class
- eager-load Eloquent relationships to prevent N+1 queries
- protect models from mass assignment
- process large record sets in chunks

## Example prompts
- Refactor this Laravel controller and move order creation into a service.
- Check this Laravel PHP code for N+1 queries and add eager loading.
- Move this request's validation into a Form Request and protect the model from mass assignment.

# Laravel Best Practices (2025)

This guide outlines the definitive best practices for developing robust, scalable, and maintainable Laravel applications. Adhere to these principles to ensure your codebase is clean, performant, and secure, aligning with PSR-12, PHP The Right Way, and Laravel's conventions.

## 1. Code Organization & Structure

### 1.1 Thin Controllers, Fat Models/Services

Controllers orchestrate requests; they do not contain business logic. Delegate complex operations to dedicated Service classes or Model methods.

❌ **BAD: Business logic in Controller**
```php
// app/Http/Controllers/OrderController.php
class OrderController extends Controller
{
    public function store(Request $request)
    {
        $order = new Order();
        $order->user_id = Auth::id();
        $order->total = $request->input('price') * 1.20; // Calculate total with tax
        $order->status = 'pending';
        $order->save();

        // ... more logic
    }
}
```

✅ **GOOD: Delegate to a Service**
```php
// app/Services/OrderService.php
class OrderService
{
    public function createOrder(array $data): Order
    {
        $order = new Order();
        $order->user_id = $data['user_id'];
        $order->total = $data['price'] * 1.20; // Business logic encapsulated
        $order->status = 'pending';
        $order->save();

        return $order;
    }
}

// app/Http/Controllers/OrderController.php
use App\Services\OrderService;

class OrderController extends Controller
{
    public function __construct(private OrderService $orderService) {}

    public function store(Request $request)
    {
        $order = $this->orderService->createOrder([
            'user_id' => Auth::id(),
            'price' => $request->input('price'),
        ]);

        return response()->json($order, 201);
    }
}
```

### 1.2 Centralized Validation with Form Requests

Always use Form Request classes for validation. This keeps controllers clean and validation logic reusable.

❌ **BAD: Validation in Controller**
```php
// app/Http/Controllers/PostController.php
class PostController extends Controller
{
    public function store(Request $request)
    {
        $request->validate([
            'title' => ['required', 'string', 'max:255'],
            'body' => ['required', 'string'],
        ]);
        // ...
    }
}
```

✅ **GOOD: Dedicated Form Request**
```php
// app/Http/Requests/StorePostRequest.php
class StorePostRequest extends FormRequest
{
    public function authorize(): bool { return true; } // Or implement authorization logic

    public function rules(): array
    {
        return [
            'title' => ['required', 'string', 'max:255'],
            'body' => ['required', 'string'],
        ];
    }
}

// app/Http/Controllers/PostController.php
use App\Http\Requests\StorePostRequest;

class PostController extends Controller
{
    public function store(StorePostRequest $request)
    {
        // Validated data is automatically available
        $post = Post::create($request->validated());
        return response()->json($post, 201);
    }
}
```

## 2. Common Patterns & Anti-patterns

### 2.1 Eloquent Over Raw Queries (and Eager Loading)

Prefer Eloquent ORM for database interactions. Always eager load relationships to prevent N+1 query problems.

❌ **BAD: Raw queries & N+1 problem**
```php
// In a controller or view
$users = DB::select('SELECT * FROM users');
foreach ($users as $user) {
    echo $user->profile->bio; // N+1 query for each profile
}
```

✅ **GOOD: Eloquent with eager loading**
```php
// In a controller
$users = User::with('profile')->get();
// In a Blade template (data passed from controller)
@foreach ($users as $user)
    {{ $user->profile->bio }}
@endforeach
```

### 2.2 Collections Over Arrays

Leverage Laravel's powerful Collection class for data manipulation.

❌ **BAD: Manual array manipulation**
```php
