Routing

All Laravel routes are defined in your route files, which are located in the routes directory. These files are automatically loaded by the framework.

Ways to Route


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


Route::get('/about', function () {
    return '<h1>About Laravel</h1>';
});


Route::get('/about', function () {
    return view('welcome.blade.php');
    //return view('welcome');
});

Group Routes

    Route::group(['prefix' => 'ajax'], function(){
        Route::group(['prefix' => 'blog'], function(){
            Route::post('blog', 'blogController@Status');

Views

Views contain the HTML served by your application and separate your controller / application logic from your presentation logic.

 

Stored in the resources/views directory

 

<html>
    <body>
        <h1> Hello, World </h1>
    </body>
</html>

Passing Data

Route::get('/about', function () {
    return view('about', [
        'title' => "Intro to Laravel",
    ]);
});


Route::get('/about', function () {
    return view('about')->with('title', 'Intro to Laravel');
});

Route::get('/about', function () {

    $title = 'Intro to Laravel';
    $group = 'Miami SoFlo PHP';
    $sections = ['Set up', 'Laradock', 'Routing', 'Views', 'Controllers'];

    return view('about', compact('title', 'group', 'sections'));
//    return view('about',  [
//        'title' => $title,
//        'group' => $group
//    ]);

});

Data in Views




<h1> <?php echo $title; ?> </h1>

<?php 
 
echo "<h5> $group </h5>";

?>

<ul>

    <?php foreach( $sections as $section):?>

        <li> $section  </li>

    <?php endforeach; ?>

</ul>

Blade

<?php if ($condition): ?>
    { do something }
<?php endif; ?>

<?php foreach ($conditions as $condition) { ?>
    { do something }
<?php } ?>

<div> <?php echo $variable; ?> </div>

<?php require('/layouts/nav_bar.php'); ?>
@if ($condition)
    { do something }
@endif

@foreach($conditions as $condition)
    { do something }
@endforeach

<div> {{variable}} </div>

include('layouts.nav')

 Default templating engine provided by Laravel.

 




<h1> {{ $title }} </h1>

<h5> {{ $group }} </h5>

<ul>

    @foreach( $sections as $section)

        <li> {{ $section }} </li>

    @endforeach

</ul>


<h1> <?php echo $title; ?> </h1>

<?php 
 
echo "<h5> $group </h5>";

?>

<ul>

    <?php foreach( $sections as $section):?>

        <li> $section  </li>

    <?php endforeach; ?>

</ul>

Vanilla PHP

Blade

Layouts

@yield

 

@section

 

@extends

 

@include

 

<!doctype html>
<html>

    <head>  
        <title>Laravel</title>
    </head>
    
    <body>
        
        <header>
            @include('layout.nav)
        </header>

        @yield('content')

        <footer>
            @include('layout.footer)
         </footer>

    </body>

</html>

Controllers

Instead of defining all of your request handling logic as Closures in route files, you may wish to organize this behavior using Controller classes. Controllers can group related request handling logic into a single class.


Stored in the app/Http/Controllers.

Basic Controller

Subtitle




namespace App\Http\Controllers;

use Illuminate\Http\Request;

class AboutPageController extends Controller
{
    

    public function about()
    {
    
        // do something
       
    }
}

Artisan Make Command

php artisan make:controller AboutPageController

Routes & Controllers

 


-------- Routes File ---------


Route::get('/about', 'AboutPageController@about');


------ Controller File -------


class AboutPageController extends Controller
{
    //

    public function about()
    {

        $title = 'Intro to Laravel';
        $group = 'Miami SoFlo PHP';
        $sections = ['Set up', 'Laradock', 'Routing', 'Views', 'Controllers'];

        return view('about', compact('title', 'group', 'sections'));
    }
}
