Install the following to get started:

• IDE like Visual Studio Code
• PHP
• A terminal like Git Bash
• A database like mariaDB and/or a visual database manager like TablePlus
• npm (for JavaScript packages)
• composer

Open your terminal and move to where you want to make your project using the terminal command 'cd' followed by the route. And make a directory using 'mkdir', move into it with cd again.

cd Documents/WebDesign
mkdir LaravelProject
cd LaravelProject

In your terminal run the following command to make a new Laravel base project

composer create-project laravel/laravel .

You can now test if everything works by running the following command, and going to localhost:8000 in your browser.

php artisan serve

It works? Great! Moving on...

This file contains all the routes your website can access. this can include pages, but also POST/GET/... requests to edit items.

There is a standard route included. Routes return views which are in essence pages.

// 
Route::get('/', function () {
    return view('welcome');
});

In this piece of code:

• the Method is 'get'
• the endpoint is / ('localhost:8000/')
• and when this page is requested the route will return a view 'welcome'.

Notes:

• If you want to see all the endpoints you can use the command:

php artisan route:list

• When creating routes you can name them using '->name('name')'

Folder:resources/views As stated above, the route returns a view 'welcome'. But what does this mean?

Well in this folder you can spot the '*.blade.php' file. When calling a view, Laravel looks in this folder and finds the file with the same name. In this case 'welcome'. The PHP server processes this file and sends back HTML to the user.

Note:

• When returning a view you can pass variables using '->with('name', $value)'

There are a couple of commands that make your life easier in Laravel! they create the base files. (wow!)

php artisan make:controller ControllerName

if you want a full list of artisan make commands use this:

php artisan make:help

If you never worked with a mvc structure, don't worry.
A controller is the step between your routes and your view. It prepares the data needed. This is where you create functions like 'store' to save data, 'show' to return a view, or others to perfom some logic.

Lets create a controller using the artisan make: command and tinker with it!

<?php
namespace App\Http\Controllers;
//MAKE SURE TO IMPORT CORRECTLY
use Illuminate\Contracts\View\View;
use Illuminate\Http\Request;

class TestController extends Controller
{
    function hello() : View {
        return view('hello');
    }
}

When you have a controller you're going to want to edit you web.php file to use the following syntax:

//MAKE SURE TO IMPORT CORRECTLY
use App\Http\Controllers\TestController;

Route::get('/hello', [TestController::class, 'hello']);

You'll notice the only part that changed, is where a function used to be. now we call the controller followed by what function we want to call.

First lets create a new model with the folowing command:

php artisan make:model ModelName

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=DevArticle <- name of database you're gonna create
DB_USERNAME=root
DB_PASSWORD=super secret password

Great! Now just create a new database (ctrl+k & new in tablePlus) and next we're gonna set up migrations for your model.
Once migrations are done everything should be connected.

php artisan make:migration create_ModelName+s_table

Once you have your migration it should look like this:

    public function up(): void
    {
        Schema::create('modelName+s', function (Blueprint $table) {
            $table->id();
            $table->timestamps();
        });
    }
    public function down(): void
    {
        Schema::dropIfExists('modelName+s');
    }

You can add aditional columns by adding more tows to the up function.The syntax is the following $table->type('column_name'). For example $table->text('last_name') or $table->integer('age')

1. Let's make a model, migration and controller for an object called 'Car' and lets add some columns in your migration.

    public function up(): void
    {
        Schema::create('cars', function (Blueprint $table) {
            $table->id();
            $table->text('model');
            $table->text('make');
            $table->text('color');
            $table->timestamps();
        });
    }

In the code above, we create colums with type 'text'. There are a lot of types, make sure to look up what type you need for your use case.

When you have edited the migration you can run the following command to create the corresponding tables:

php artisan migrate

1. Lets create two endpoints for a form, to create a new Car instance.

Route::get('/create',[CarController::class, 'form'])->name('createCar');
Route::post('/store',[CarController::class, 'store'])->name('storeCar');

use App\Models\Car;
use Illuminate\Contracts\View\View;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Redirect;
class CarController extends Controller
{
    function form() : View {
        return view('createCar');
    }
    function store(Request $request) : RedirectResponse {
        $car = new Car();
        $car->model = $request->input('model');
        $car->make = $request->input('make');
        $car->color = $request->input('color');
        $car->save();

        return Redirect::back();
    }
}

In the store function we create a new instance of the Car model. Then we add the properties using the $request->input('inputname') to access the submitted form data. Lastly we save and redirect back to the page we where just at.
Now just the views are left!

Lets create the createCar.blade.php, we'll want the basic html structure (untill we get to layouts), and add the following form.

    <form action="{{route('storeCar')}}" method="post">
        @csrf
        <label>Model
        <input type="text" name='model' id='model'>
        </label>
        <label>Make
        <input type="text" name='make' id='make'>
        </label>
        <label>Color
        <input type="text" name='color' id='color'>
        </label>
        <button type="submit">Save</button>
    </form>

In blade files we can use the @ directives for a few things. One of them is @csrf which adds a layer of protection to forms.

If you implemented these changes you can go to /create and create a new instance of a car. Check your database after saving (make sure to refresh), and there should be a car present!

In the next part we will check out layout and component files. and we'll display the data we just saved.

Directives

Directives always start with '@'. These are the ones you'll use most often:
** @extends('file') **
This is used for layout files.
** @include('component',['var' => "data",'var2' => "data"]) **
this is used for components you want to use multiple times that require data.
** @yield('sectionName') & @section('sectionName') @endsection **
You can use @yield in the layout file to indicate where to insert a section from another file.
The @section() @endsection is used to indicate what content is suposed to go where.

There are also directives that are used for logic. This means you no longer have to open and close php tags all the time! some examples include:
@if(), @elseif(), @else, @endif
@foreach(), @endforeach
@for(), @endfor
@while(), @endwhile

In forms we ALWAYS use @csrf, also optionally we can use @method() to change the way we submit (GET/POST/PUT/...)

Layout

Lets make a layout file. First in the views folder create a subfolder called layout. In this folder we create a file layout.blade.php

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@yield('title')</title>
</head>
<body>
    @yield('content')
</body>
</html>

and lets apply this layout file to all our views like this:

@extends('layout.layout')
@section('title')
    Hello
@endsection
@section('content')
    <h1>Hello world!</h1>
@endsection

You can also add layout parts like header, footer, navigation, etc into the layout folder and @include() them.

Okay now lets create a blade file to show all cars. (add the necessary route and controller logic)
web.php

Route::get('/cars', [CarController::class, 'show'])->name('showCars');

CarController.php

    function show() : view {
        $cars = Car::all();
        return view('cars')
        ->with('cars',$cars);
    }

cars.blade.php

@extends('layout.layout')
@section('title')
    Car Collection
@endsection
@section('content')
    <h1>Cars</h1>
    @if(!$cars->isEmpty())
        @foreach($cars as $car)
            <div>
                <h3>{{$car->make}}</h3>
                <p>{{$car->model}}</p>
                <p>{{$car->color}}</p>
            </div>
        @endforeach
    @else
        <h1>Add some cars first!</h1>
    @endif
@endsection

packages

There are a ton of packages. These can add functionality to your project, or make coding easier.
The main two types are npm and composer. Npm uses node.js and composer is php oriented.

We'll start with a simple php debug bar.
(https://github.com/barryvdh/laravel-debugbar)
In your terminal use the following command:

composer require barryvdh/laravel-debugbar --dev

(this might take a few minutes depending on the package)
Using --dev makes sure the package is only used in development.

If you refresh, there should be a Laravel icon in the bottom left, click it for the debug bar!
wow so easy!

css

Folder:resources/css/app.css
In the head of the layout file you can add the following line:

@vite("resources/css/app.css")

Now we will need to open a second terminal and navigate to the root of your project again. Here we want to run the following commands:

npm install
npm run dev

Make sure your final css is compiled into the app.css file and your good to go!

slugs

Slugs are pieces in your url that signify a value like an id or name. in your web.php file you determine where the slugs are expected:

Route::get('/car/{id}', [CarController::class, 'showCar'])->name('showCar');

Then you can use it in your controller like this:

    function showCar($id) : view {
        $car = Car::find($id);
        return view('car')
        ->with('car',$car);
    }
