Laravel Basics | Installation to basic website

Welcome to the most practical and easy step by step information on how to install laravel in your computer.

First of all, Install Composer if you have not installed it yet.

Install WAMP

c:\wamp64\www>composer create-project laravel/laravel helloworld

Views (C:\wamp64\www\helloworld\resources\views)

  • C:\wamp64\www\helloworld\resources\views\hi.blade.php

Routes (C:\wamp64\www\helloworld\routes)

C:\wamp64\www\helloworld\routes\web.php

Route::get(‘hii’, function () {
return view(‘hi’);
});


Create a new template file in a new subfolder views\layouts\app.blade.php

<html>
<head>
<title>App Name – @yield(‘title’)</title>
</head>
<body>
@section(‘sidebar’)
This is the master sidebar.
@show

<div class=”container”>
@yield(‘content’)
</div>
</body>
</html>


Create  a new Controller as Http\Controllers\MainController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

class MainController extends Controller
{
/**
* Show the profile for the given user.
*
* @param int $id
* @return View
*/
public function show()
{
return view(‘layouts.app’);
}
}


Create the route

Route::get(‘start’, ‘MainController@show’);


Test by pointing location to http://localhost/helloworld/public/start

It will call the MainController.
MainController will load the view


For Authentication (Login Username)

C:\wamp64\www\helloworld1>php artisan make:auth

For Database Creation:

C:\wamp64\www\helloworld1>php artisan migrate


Some Common Errors:

SQLSTATE[HY000] [1045] access denied for the user: ‘homestead’@’@localhost’ (password: YES)

Solution:

Check .env file and make sure you have updated the mysql username and password:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_hello
DB_USERNAME=root
DB_PASSWORD=root

Format of the migration files should be as below:

2018_01_15_100000_create_users_table.php

How to refer to site url in views
href=”{{ url(‘/tasks’) }}”


Validate

$validator = Validator::make($request->all(), [
‘title’ => ‘required|email’,
‘description’ => ‘required’,

]);


Fillable | Model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Task extends Model
{
protected $fillable = [‘title’,’description’];
}


Check whether user is logged in or not in controller

use Auth;

if(Auth::check())
{
$tasks = Task::all();
return view(‘tasks.index’,compact(‘tasks’,$tasks));
}
else
{
return redirect(‘/login’);
}


App Name can be changed in .env

APP_NAME=’aaa aaa aaa’

In the template file it can be referenced as {{ config(‘app.name’) }}
