1. Routing: Basic Route Example

// routes/web.php

use App\Http\Controllers\HomeController;
Route::get('/', [HomeController::class, 'index']);

This is a basic route in Laravel. The Route::get() method handles HTTP GET requests, and it's associated with a controller method (HomeController@index).

---

2. Controller Method

// app/Http/Controllers/HomeController.php


namespace App\Http\Controllers;
use Illuminate\Http\Request;
class HomeController extends Controller
{
    public function index()
    {
        return view('welcome');
    }
}

A simple controller method that returns a view called welcome. Controllers are used to handle incoming requests and return responses.

---

3. Eloquent ORM: Retrieving Data

// Retrieving all users from the users table

$users = App\Models\User::all();

This code uses Eloquent to fetch all records from the users table. User is the model corresponding to the users table.

---

4. Eloquent ORM: Filtering Data

// Fetching users where the name is 'John'

$john = App\Models\User::where('name', 'John')->get();

This is a basic example of using the where() method in Eloquent to filter data. You can chain multiple conditions as needed.

---

5. Blade Templating: Passing Data to Views

// Controller method

public function index()
{
    $data = ['title' => 'Laravel Blade Example', 'content' => 'This is a test page using Blade templating.'];
    return view('home', $data);
}

In your home.blade.php view, you can display the passed data like this:

{{ $title }}
{{ $content }

---

6. Form Submission with Validation

// routes/web.php

Route::post('/submit-form', [FormController::class, 'submit'])->name('form.submit');
// FormController.php
public function submit(Request $request)
{
    $request->validate([
        'email' => 'required|email',
        'password' => 'required|min:8',
    ]);
    
    // Form submission logic here
}

In this example, we use Laravel's built-in validation methods to validate form data before submission.

---

7. Database Migration

// Create a new migration file for creating a posts table

php artisan make:migration create_posts_table --create=posts
// Inside the migration file:
public function up()
{
    Schema::create('posts', function (Blueprint $table) {
        $table->id();
        $table->string('title');
        $table->text('content');
        $table->timestamps();
    });
}
public function down()
{
    Schema::dropIfExists('posts');
}

Migrations in Laravel allow you to define your database schema in PHP and keep track of changes. You can run the migration with php artisan migrate.

---

8. Middleware: Protecting Routes

// routes/web.php

Route::middleware(['auth'])->group(function () {
    Route::get('/dashboard', [DashboardController::class, 'index']);
});

This code snippet ensures that only authenticated users can access the /dashboard route. The auth middleware checks if the user is logged in.

---

9. File Upload Handling

// In a controller method

public function store(Request $request)
{
    $request->validate([
        'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
    ]);
    
    if ($request->hasFile('image')) {
        $image = $request->file('image');
        $imageName = time() . '.' . $image->getClientOriginalExtension();
        $image->move(public_path('images'), $imageName);
        
        return back()->with('success', 'Image uploaded successfully!');
    }
    
    return back()->withErrors(['image' => 'No image selected.']);
}

This code handles file upload validation and saving the file to the public/images directory.

---

10. Authentication: Login Form

// routes/web.php

Route::get('/login', [Auth\LoginController::class, 'showLoginForm'])->name('login');
Route::post('/login', [Auth\LoginController::class, 'login']);
// In the LoginController
public function showLoginForm()
{
    return view('auth.login');
}

This is a basic authentication setup for showing a login form and handling the login process.

---

11. API Route Example

// routes/api.php

Route::get('/users', [UserController::class, 'index']);

This defines an API route that fetches a list of users from the UserController when a GET request is made to /api/users.
