Routing {.cols-3}

Router HTTP Methods {.row-span-2}

Route::get($uri, $callback);
Route::post($uri, $callback);
Route::put($uri, $callback);
Route::patch($uri, $callback);
Route::delete($uri, $callback);
Route::options($uri, $callback);

Multiple HTTP methods

Route::match(['get', 'post'], '/', function () {
    //
});

Route::any('/', function () {
    //
});

Basic Definition {.row-span-2}

use Illuminate\Support\Facades\Route;

// closure
Route::get('/greeting', function () {
    return 'Hello World';
});

// controller action
Route::get(
    '/user/profile',
    [UserProfileController::class, 'show']
);

Dependency Injection

use Illuminate\Http\Request;

Route::get('/users', function (Request $request) {
    // ...
});

Type hint concrete dependencies for auto-injection

View Routes

// Argument 1: URI, Argument 2: view name
Route::view('/welcome', 'welcome');

// with data
Route::view('/welcome', 'welcome', ['name' => 'Taylor']);

Route only needs to return a view.

Route Model Binding {.row-span-4}

Implicit binding

With closure

use App\Models\User;

Route::get('/users/{user}', function (User $user) {
    return $user->email;
});

// /user/1 --> User::where('id', '=', 1);

With controller action

use App\Http\Controllers\UserController;
use App\Models\User;

// Route definition...
Route::get('/users/{user}', [UserController::class, 'show']);

// Controller method definition...
public function show(User $user)
{
    return view('user.profile', ['user' => $user]);
}

With custom resolution column

use App\Models\Post;

Route::get('/posts/{post:slug}', function (Post $post) {
    return $post;
});

// /posts/my-post --> Post::where('slug', '=', 'my-post');

Always use a different column to resolve

// in App\Models\Post
public function getRouteKeyName()
{
    return 'slug';
}

Multiple models - second is child of first

use App\Models\Post;
use App\Models\User;

Route::get('/users/{user}/posts/{post:slug}', function (User $user, Post $post) {
    return $post;
});

Convenient way to automatically inject the model instances directly into your routes

Route Parameters {.row-span-2}

Capture segments of the URI within your route

Required parameters

Route::get('/user/{id}', function ($id) {
    return 'User '.$id;
});

With dependency injection

use Illuminate\Http\Request;

Route::get('/user/{id}', function (Request $request, $id) {
    return 'User '.$id;
});

Optional Parameters

Route::get('/user/{name?}', function ($name = null) {
    return $name;
});

Route::get('/user/{name?}', function ($name = 'John') {
    return $name;
});

Redirect Routes

HTTP 302 status

Route::redirect('/here', '/there');

Set the status code

Route::redirect('/here', '/there', 301);

Permanent 301 redirect

Route::permanentRedirect('/here', '/there');

Regular Expression Constraints {.cols-2}

Route::get('/user/{name}', function ($name) {
    //
})->where('name', '[A-Za-z]+');

Route::get('/user/{id}', function ($id) {
    //
})->where('id', '[0-9]+');

Route::get('/user/{id}/{name}', function ($id, $name) {
    //
})->where(['id' => '[0-9]+', 'name' => '[a-z]+']);

Named Routes

Route names should always be unique

Route::get('/user/profile', function () {
    //
})->name('profile');

See: Helpers

Fallback Routes

Route::fallback(function () {
    //
});

Executed when no other routes match

Route Groups

Middleware

Route::middleware(['first', 'second'])->group(function () {
    Route::get('/', function () {
        // Uses first & second middleware...
    });

    Route::get('/user/profile', function () {
        // Uses first & second middleware...
    });
});

URI Prefixes

Route::prefix('admin')->group(function () {
    Route::get('/users', function () {
        // Matches The "/admin/users" URL
    });
});

Name Prefix

Route::name('admin.')->group(function () {
    Route::get('/users', function () {
        // Route assigned name "admin.users"...
    })->name('users');
});

Share attributes across routes

Accessing current route

use Illuminate\Support\Facades\Route;

// Illuminate\Routing\Route
$route = Route::current();

// string
$name = Route::currentRouteName();

// string
$action = Route::currentRouteAction();

Helpers {.cols-3}

routes {.row-span-2}

Named route

$url = route('profile');

With parameters

// Route::get('/user/{id}/profile', /*...*/ )->name('profile);

$url = route('profile', ['id' => 1]);

// /user/1/profile/

With query string

// Route::get('/user/{id}/profile', /*...*/ )->name('profile);

$url = route('profile', ['id' => 1, 'photos'=>'yes']);

// /user/1/profile?photos=yes

Redirects

// Generating Redirects...
return redirect()->route('profile');

Eloquent Models

echo route('post.show', ['post' => $post]);

The route helper will automatically extract the model's route key. See Routing

URL Generation

Generate arbitrary URLs for your application that will automatically use the scheme (HTTP or HTTPS) and host from the current request

$post = App\Models\Post::find(1);

echo url("/posts/{$post->id}");

// http://example.com/posts/1

Current URL

// Get the current URL without the query string...
echo url()->current();

// Get the current URL including the query string...
echo url()->full();

// Get the full URL for the previous request...
echo url()->previous();

Named Route URL

$url = route('profile');

See Named Route

Error Handling

public function isValid($value)
{
    try {
        // Validate the value...
    } catch (Throwable $e) {
        report($e);

        return false;
    }
}

Report an exception but continue handling the current request

HTTP Exceptions

// page not found
abort(404);

Generate an HTTP exception response using status code

Controllers {.cols-3}

Basic

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use App\Models\User;

class UserController extends Controller
{
    public function show($id)
    {
        return view('user.profile', [
            'user' => User::findOrFail($id)
        ]);
    }
}

Define a route for this controller method:

use App\Http\Controllers\UserController;

Route::get('/user/{id}', [UserController::class, 'show']);

Requests {.cols-3}

CSRF Protection

Laravel automatically generates a CSRF "token" for each active user session.
This token is used to verify that the authenticated user is the person actually making the requests.

Get current session's token:

Route::get('/token', function (Request $request) {
    $token = $request->session()->token();

    $token = csrf_token();

    // ...
});

POST, PUT, PATCH, or DELETE forms should include a hidden CSRF _token field in the form to validate the request.

<form method="POST" action="/profile">
    @csrf

    <!-- Equivalent to... -->
    <input type="hidden" name="_token" value="{{ csrf_token() }}" />
</form>

See Forms

Accessing Request

Get an instance of the current request by type-hinting the controller action or route closure

// controller action
class UserController extends Controller
{
    public function store(Request $request)
    {
        $name = $request->input('name');
    }
}

// closure
Route::get('/', function (Request $request) {
    //
});

See Routing

Path

The request's path information

$uri = $request->path();

// https://example.com/foo/bar --> foo/bar

Match path to pattern

Verify that the incoming request path matches a given pattern

// * is wildcard
if ($request->is('admin/*')) {
    //
}

Determine if the incoming request matches a named route

if ($request->routeIs('admin.*')) {
    //
}

URL

Full URL for the incoming request

// URL without the query string
$url = $request->url();

// URL including query string
$urlWithQueryString = $request->fullUrl();

// append data to query string
$request->fullUrlWithQuery(['type' => 'phone']);

Request Method

$method = $request->method();

// verify that the HTTP verb matches a given string
if ($request->isMethod('post')) {
    //
}

Client IP

$ipAddress = $request->ip();

Headers

$value = $request->header('X-Header-Name');

$value = $request->header('X-Header-Name', 'default value');

// determine if the request contains a given header
if ($request->hasHeader('X-Header-Name')) {
    //
}

// retrieve a bearer token from the Authorization header
$token = $request->bearerToken();

Content Type

Return an array containing all the content types accepted by the request

$contentTypes = $request->getAcceptableContentTypes();

Boolean check for content types are accepted by the request

if ($request->accepts(['text/html', 'application/json'])) {
    // ...
}

Input {.row-span-4}

Retrieve all the incoming request's input data as an array

$input = $request->all();

Retrieve all the incoming request's input data as a collection

$input = $request->collect();

// retrieve subset as collection
$request->collect('users')->each(function ($user) {
    // ...
});

See Helpers

Retrieve user input (also gets values from query string)

$name = $request->input('name');

// with default value if none present
$name = $request->input('name', 'Sally');

Access array inputs

$name = $request->input('products.0.name');

$names = $request->input('products.*.name');

Retrieve all the input values as an associative array:

$input = $request->input();

Only retrieve values from the query string:

$name = $request->query('name');

// with default value
$name = $request->query('name', 'Helen');

Retrieve all the query string values as an associative array:

$query = $request->query();

Boolean Input Values

Helpful for checkbox inputs or other booleans. Return true for 1, "1", true, "true", "on", and "yes".
All other values will return false

$archived = $request->boolean('archived');

Dynamic Properties

Access inputs via properties.
If not found as an input, the route parameters will be checked.

$name = $request->name;

Retrieve Partial Input

$input = $request->only(['username', 'password']);

$input = $request->only('username', 'password');

$input = $request->except(['credit_card']);

$input = $request->except('credit_card');

Check Existence

Determine if value(s) present

if ($request->has('name')) {
    //
}

// check if ALL values are present
if ($request->has(['name', 'email'])) {
    //
}

// if any values are present
if ($request->hasAny(['name', 'email'])) {
    //
}

Old Input

Retrieve input from the previous request

$username = $request->old('username');

Or use the old() helper

<input type="text" name="username" value="{{ old('username') }}">

See: Helpers
See: Forms

Uploaded Files

Retrieve uploaded file from request

$file = $request->file('photo');

$file = $request->photo;

Get file path or extension

$path = $request->photo->path();

$extension = $request->photo->extension();

Store uploaded file with a randomly generated filename

// path where the file should be stored relative to
// the filesystem's configured root directory
$path = $request->photo->store('images'); 

// optional 2nd param to specify the filesystem disk
$path = $request->photo->store('images', 's3');

Store uploaded file and specify the name

$path = $request->photo->storeAs('images', 'filename.jpg');

$path = $request->photo->storeAs('images', 'filename.jpg', 's3');

Displaying Data

Blade's echo statements {{ }} are automatically sent through PHP's htmlspecialchars function to prevent XSS attacks.

Display the contents of the name variable:

Hello, {{ $name }}.

Display results of a PHP function:

The current UNIX timestamp is {{ time() }}.

Display data without escaping with htmlspecialchars

Hello, {!! $name !!}.

Including Subviews

Include a Blade view from within another view.
All variables that are available to the parent view are also available to the included view

<div>
    <!-- resources/views/shared/errors/blade.php -->
    @include('shared.errors')

    <form>
        <!-- Form Contents -->
    </form>
</div>

Raw PHP

Execute a block of plain PHP

@php
    $counter = 1;
@endphp

Stacks

Blade allows you to push to named stacks which can be rendered in another view or layout.
Useful for javascript libraries required by child views

<!-- Add to the stack -->
@push('scripts')
    <script src="/example.js"></script>
@endpush

Render the stack

<head>
    <!-- Head Contents -->

    @stack('scripts')
</head>

Prepend to the beginning of a stack

@push('scripts')
    This will be second...
@endpush

// Later...

@prepend('scripts')
    This will be first...
@endprepend

Forms {.cols-3}

Intro

Laravel Docs - Forms

CSRF Field

Include a hidden CSRF token field to validate the request

<form method="POST" action="/profile">
    @csrf
    
    ...
</form>

See: CSRF Protection

Method Field

Since HTML forms can't make PUT, PATCH, or DELETE requests, you will need to add a hidden _method field to spoof these HTTP verbs:

<form action="/post/my-post" method="POST">
    @method('PUT')

    ...
</form>

Validation Errors

<!-- /resources/views/post/create.blade.php -->

See: Validation

Repopulating Forms

When redirecting due to a validation error, request input is flashed to the session.
Retrieve the input from the previous request with the old method

$title = $request->old('title');

Or the old() helper

<input type="text" name="title" value="{{ old('title') }}">

Validation {.cols-3}

Intro

Laravel Docs - Validation

If validation fails, a redirect response to the previous URL will be generated.
If the incoming request is an XHR request, a JSON response with the validation error messages will be returned.

Logic

// in routes/web.php
Route::get('/post/create', [App\Http\Controllers\PostController::class, 'create']);
Route::post('/post', [App\Http\Controllers\PostController::class, 'store']);

// in app/Http/Controllers/PostController...
public function store(Request $request)
{
    $validated = $request->validate([
        // input name => validation rules
        'title' => 'required|unique:posts|max:255',

Password::min(8)

// Require at least one letter...
Password::min(8)->letters()

// Require at least one uppercase and one lowercase letter...
Password::min(8)->mixedCase()

// Require at least one number...
Password::min(8)->numbers()

Password::min(8)->symbols()

Ensure a password has not been compromised in a public password data breach leak

Password::min(8)->uncompromised()

Uses the k-Anonymity model via the haveibeenpwned.com service without sacrificing the user's privacy or security

Methods can be chained

Password::min(8)
    ->letters()

Optional Fields

You will often need to mark your "optional" request fields as nullable if you do not want the validator to consider null values as invalid

// publish_at field may be either null or a valid date representation
$request->validate([
    'title' => 'required|unique:posts|max:255',
    'body' => 'required',
    'publish_at' => 'nullable|date',
]);

Validated Input

Retrieve the request data that underwent validation

$validated = $request->validated();

Or with safe(), which returns an instance of Illuminate\Support\ValidatedInput

$validated = $request->safe()->only(['name', 'email']);

$validated = $request->safe()->except(['name', 'email']);

$validated = $request->safe()->all();

Iterate

foreach ($request->safe() as $key => $value) {
    //

Access as an array

$validated = $request->safe();

$email = $validated['email'];

Session {.cols-3}

Intro

Laravel Docs - Session

Laravel ships with a variety of session backends that are accessed through a unified API. Memcached, Redis, and database support is included.

Configuration

Session configuration is in config/session.php.
By default, Laravel is configured to use the file session driver

Check Isset / Exists

Returns true if the item is present and is not null:

if ($request->session()->has('users')) {
    //
}

Returns true if present, even if it's null:

if ($request->session()->exists('users')) {
    //
}

Returns true if the item is null or is not present:

if ($request->session()->missing('users')) {
    //
}

Retrieving Data {.row-span-2}

Via Request

// ...
class UserController extends Controller
{
    public function show(Request $request, $id)
    {
        $value = $request->session()->get('key');

        //
    }
}

Pass a default value as the second argument to use if the key does not exist

$value = $request->session()->get('key', 'default');

// closure can be passed and executed as a default
$value = $request->session()->get('key', function () {
    return 'default';
});

Via session helper

Route::get('/home', function () {
    // Retrieve a piece of data from the session...
    $value = session('key');

    // Specifying a default value...
    $value = session('key', 'default');

    // Store a piece of data in the session...
    session(['key' => 'value']);
});

See: Session Helper

Logging {.cols-3}

Configuration

Configuration options for logging behavior is in config/logging.php.
By default, Laravel will use the stack channel when logging messages, which aggregates multiple log channels into a single channel.

Levels {.row-span-2}

All the log levels defined in the RFC 5424 specification are available:

emergency
alert
critical
error
warning
notice
info
debug

Log Facade {.row-span-2}

use Illuminate\Support\Facades\Log;

Log::emergency($message);
Log::alert($message);
Log::critical($message);
Log::error($message);
Log::warning($message);
Log::notice($message);
Log::info($message);
Log::debug($message);

Contextual Info

use Illuminate\Support\Facades\Log;

Log::info('User failed to login.', ['id' => $user->id]);

Deployment {.cols-3}

Intro

Laravel Docs - Deployment

Ensure your web server directs all requests to your application's public/index.php file

Optimization

Composer's autoloader map

composer install --optimize-autoloader --no-dev

Configuration Loading

Be sure that you are only calling the env function from within your configuration files.
Once the configuration has been cached, the .env file will not be loaded and all calls to the env function for .env variables will return null

php artisan config:cache

Route Loading

php artisan route:cache

View Loading

php artisan view:cache

Debug Mode

The debug option in your config/app.php determines how much information about an error is actually displayed to the user.
By default, this option is set to the value of the APP_DEBUG environment variable in your .env file. In your production environment, this value should always be false.
If the APP_DEBUG variable is set to true in production, you risk exposing sensitive configuration values to end users.
