LARAVEL DERSLERI



Composer qurulumu :

https://getcomposer.org/download/ - bu linkden composer-setup.exe yuklenir

Proxy varsa set edilir url

Laravel qurulumu:

Daha sonra cmd-dan asagidaki command ile laravel qurulur:

Composer create-project laravel/laravel test

Test- folder namedir

http://localhost:9090/test/public/

Eger asagidaki error verirse

Warning: require(C:\xampp\htdocs\test\public/../vendor/autoload.php): failed to open stream: No such file or directory in C:\xampp\htdocs\test\public\index.php on line 24

Fatal error: require(): Failed opening required 'C:\xampp\htdocs\test\public/../vendor/autoload.php' (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\test\public\index.php on line 24

Test foldeirne cd edib orda composer install buraxin

Daha sonra eger asagidaki kimi eror alsaz :

No application encryption key has been specified. New Laravel app

Asagidaki commandi buraxin

Php artisan key:generate

Konfigurasiya zamani asagidakilara diqqet yetirin

1)storage ve bootstrap/cache read write icazesi olmalidir

2)key generate ile key generate olunmalidir

3)esas folderde .env faylinin olmasi lazimdir

LARAVEL STRUKTURU

App- esas modulumuz app folderidir demek olar

Bootstrap - autoload ve cache hissesi buradad tutulur

Config - config fayllar burada tutulur

Datatabse - database emelyatlari ucun istifade olunan seed ve migration burada istifade olunur

Public - programamizi calistiran hissedir. Elave olaraq assets faylarimiz dfa buradas tutulur( js, css , images ve.s)

Storage - burada cache log ve.s bilgileri tutulur

Vendor - dependecilerin tutuldugu yerdir

Config -> database.php - baza propertilerimiz burada tutulur

*** database,php-de baxsaz gorersiniz ki env metodu istfde olunur bu metod .env-deki parametrlerimiz ile isleyir

resources->views - view sehfelerimiz burada tutulur ( sonu blade olaraq bitmelidi welcome.blade.php)

Http->Controllers - controllerimiz buirada tutulur

*** php artisan make:controller AdminController

Yuxaridaki kod ile yeni controller yarada bilerik

php artisan make:controller PageController --resource

***** --resource elave etdikde ozu avtomatik CRUD metodlarini yaradir

routes->web.php - routelarimizi burada goisteririk

***** Route::get($url, $callback);

Route::post($url, $callback);

Route::put($url, $callback);

Route::patch($url, $callback);

Route::delete($url, $callback);

Route::options($url, $callback);

PUT,POST , DELETE cagiormaq ucun CSRF istifade edilmedlir!

Hem get hem post metod tanimlama

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

Web.php icerisinde asagiodaki kodu goreceyik ilk olaraq

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

return view('welcome'); //view sehfeye redirect etmek ucundur

});

Biz burada default page olaraq welcome tanitmisiq

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

return 'TEST'; //sadece text return edirik

});

Istesez controller-den de uygun funskiya cagira bilersiz url-ye gore

Route::get(‘user/profil', 'UserController@showUserProfil');

Routelerimiza ad da vere bilerik

Route::get(‘user/profil', 'UserController@showUserProfil')->name(‘profil’);

Ad verdikden sonra her hansi sehfemizde asagidaki sekilde route ede bilerik

route('profil');

Routelerimizi qruplasdria da bilirik

Route::namespace('Admin')->group(function () {

Route::get('profil', 'UserController@showUserProfil');

});

Hem burada prefix elave ederek tekrarinda qarisini ala bilirik

Route::group(['prefix'=>'getList','as'=>'account.'], function(){ Route::get('/users', ['as' => 'index', 'uses' => 'AccountController@index']); Route::get('/employees', ['as' => 'connect', 'uses' = > 'AccountController@connect']); });

Ve daha sonra bu grupa gore permisionlar vere bilerik

Burada profil routunun Admin qrupuna aid oldugunu gostririk

Rout-da parametrli url-leri gostermek ucun

Route::get('user/{id}', 'UserController@showUserProfil');

Route::get('user/{id?}', 'UserController@showUserProfil');

Yuxaridaki iki kod arasinda ferq ? isaresidir.

Eger ? varsa bu parametr ola da bielr olmaya da biler

Database -> migrations

Burada php fayl varhansiki database sql scriptleri var

Burada 2 metod olur her birinde up ve down

Up-da etdiyiniz seyin down metodunda geri qaytama hissesi olmalidir

Meselem up-da user yaraadirsinizsa down-da o uiseri islmek ucun kod olmalidir

public function up()
{
   Schema::create('users', function($table)
   {
       $table->increments('id');
       $table->string('email')->unique();
       $table->string('name');
       $table->timestamps();
   });
}

public function down()
{
   Schema::drop('users');
}

Eger datase-i migrationlariniz esasinda generate etmek istyrsiznizse bu cox sadedir

Sadece php artisan migrate yazib run etmeniz kiafeytdir

Indiye kimi oyrendiklerimiz uzerinden gelin xirda example yazaq

1)yeni form yaradiriq bunun ucun views-da form.bundles.php yaratmaliyiq

2)web.php-de riute yaziriq form url ucun

web.php

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

return view('form');

});

Route::post('/form','AdminController@post_form');

Form.blade.php

<html>

<head>

</head>

<body>

</form>

</body>

</html>

Csrf_token elave etdik cunki post-da elave etmesek islemeyecek error verecek

{{ $ fullname }} ile ise biz controllerden gonderdiyimiz deyeri html-de gostrririk

Eger request url goturmek isteseydik yeni url?name=aaa&surname=bbb

Goturmek isteseydik

Input::get(‘name’) seklinde goture bilerik

Ancaq burada Input istfde ed ebilmemizs ucvun clasimiza use Illuminate\Support\Facades\Input; import edilmelidir

Route::get('/getValues','AdminController@getUrlParams');

public function getUrlParams(){

$name=Input::get('name');

$surname=Input::get('surname');

$fullname=$name." ".$surname;

return view('form')->with('fullname',$fullname);

}

Route-da url tanimlayarken parametrlerden sonra ve ya evvel static parth stringlerini sitfde ede bilirik

Yeni meselem

test/fullname/{name}/{surname}/age/{age}

Bu sekilde url sehv deyil

Ve Controllerde metodumuzda deyerler view-muza set ederken ard arda bir nece with istfde ederek gondere bilerik

view(“users”)->with(“name”,$name)->with(“surname”,$surname)->with(“age”,$age); seklinde

Ve ya

Return view(“users”, compact($name,$surname,$age));

Seklinde istfde ede bilerik

Gelin indi bazaya insert examplemiz ile baslayaq :

1)test folderimizde asagidaki command ile modelimizi yaradiriq

Php artisan make:model users

Bu zaman app folderi altinda users.php yarandigini gore bilerik

Onun icerisine asagidaki =lari elave edirkik

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class users extends Model

{

protected $table='users'; //table adi bazada

protected $fillable=['name','surname']; //table column adlari

}

Table column adlari form-unuzdaki inout nameler ile eyni olmalidir

2)web.php-de reoutelarimizi yazriq

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

return view('users');

});

Route::post('/createUser','UserController@create');

3) users.bandle.php view-muzu yaradiriq

<html>

<head>

</head>

<body>

</form>

</body>

</html>

4)userControllerimizde metodumuzu yaziriq

public function create(Request $req)

{

$user=$req->all(); //butun request paramertrlerini alir

users::create($user); //create ile insert edirik

return "success";

}

5) .env faylimizda database propertiesleirni ozunzue uygun duzledin

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=test

DB_USERNAME=root

DB_PASSWORD=

Biz test databaseinde users tablesine insert edirik

6) table create ederken elave 2 dene datetime tipinden column elave temlsiiniz

Created_at , updated_at

**** eger bazaya zaman duzgun formada dusmurse siz timezone elave elemelisniz,

Bunun ucun config->app.php -de timezone meselem Asia/Baku yaziriq

'timezone' => 'Asia/Baku',

7) run edirik ve netice goz qabagindadir

Butun table rowlari list kimi almaq ucun

Web.php

Route::get('/userlist','UserController@getUserList');

UserController:

public function getuserList()

{

$userList=users::all();

return view('users')->with('userList',$userList);

}

Users.blade.php

<html>

<head>

</head>

<body>

</form>

{{$userList}} //siyahini ekrana vermek ucun

</body>

</html>

MiddleWare istifadesi:

Middleware ile biz pageler ucun bir nov filkterler yaradiriq

1)evvelce php artisan ile middleware create edirik

Php artisan make:middleware OldMiddleWare

2)daha sonra bunu kemel.php faylinda qeyd etmeliyik

protected $routeMiddleware = [

'auth' => \Illuminate\Auth\Middleware\Authenticate::class,

'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,

'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,

'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,

'can' => \Illuminate\Auth\Middleware\Authorize::class,

'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,

'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,

'OldMiddleWare' => \App\Http\Middleware\OldMiddleWare::class

];

3)OldMiddleWare clasimizi yaziriq

<?php

namespace App\Http\Middleware;

use Closure;

class OldMiddleWare

{

/**

* Handle an incoming request.

* @param \Illuminate\Http\Request $request

* @param \Closure $next

* @return mixed

public function handle($request, Closure $next)

{

$ip= $request->ip();

if( $ip == '::11'){

// throw new \Exception("your ip is correct");

return redirect('/');

}

return $next($request);

}

4)Routumuza middleware filterimizi tandiiriq

Route::get('/userlist','UserController@getUserList')->middleware('OldMiddleWare');

Bir nece middleware birden vere bilerik:

Route::get('/', function () {
//
})->middleware('first', 'second');

Route grup-lara da middleware vere bilerik :

Route::group(['middleware' => ['web']], function () {
//
});

Blade template istifadesi:

Views

----- layouts

----- master.blade.php

master.blade.php

<html>

<head>

<title>App Name - @yield('title')</title>

</head>

<body>

@section('sidebar')

This is the master sidebar.

@show

@yield('content')

</div>

</body>

</html>

userList.blade.php

@extends('layouts.master') // hanis layoutda gosterilcek parenti gisterilir

@section('title', 'Page Title')

@section('sidebar')

@parent

<p>This is appended to the master sidebar.</p>

@stop

@section('content')

<p>This is my body content.</p>

@stop

PAGINATION EXAMPLE

1)UserController

public function getuserList()

{

$userList=users::paginate(2); //2 sehfe edirik biz

return view('users')->with('userList',$userList);

//return view('layouts.master')->with('userList',$userList);

}

2)users.blade.php

<html>

<head>

</head>

<style>

.pagination{

list-style-type: none;

margin: 0;

padding: 10px;

overflow: hidden;

@foreach ($userList as $user)

<tr>

<td style="border:1px solid black">{{ $user->name ." ". $user->surname }} </td>

</tr>

@endforeach

</table>

</div>

</body>

</html>

LARAVEL call procedure

public function getuserList()

{

$userCount=0;

DB::statement('CALL getUserCount(@userCount)', array($userCount));

$results = DB::select('select @userCount as userCount');

return view('users')->with('userCount',$results[0]->userCount);

}

Laravel edit data row:

1)Web.php routes

Route::get('/edit/{id}', 'UserController@edit');

Route::post('edit/update/{id}', 'UserController@update');

2)Controller

public function edit($id)

{

$user=users::find($id);

return view('template.edit')->with('id',$id);

}

public function update(Request $request, $id)

{

//validate post data

$rules = array(

'name' => 'required|unique|max:255',

'surname' => 'required'

);

$validator = Validator::make(Input::all(), $rules);

if ($validator->fails()) {

return redirect('welcome');

}

else {

// store

$user = users::find($id);

$user->name = $request->name;

$user->surname =$request->surname;

$user->save();

return Redirect::to('userlist');

}

3)edit.blade.php

<html>

<head>

</head>

<body>

</form>

</body>

</html>

LARAVEL Authentication example:

1)Auth:: attempt istifade edeceyik attempt hansi cedvele baxacagini Config folderinde auth.php-de gosteririk. Biz oz model clasimizi gostermeliyik

'providers' => [

'users' => [

'driver' => 'eloquent',

'model' => App\users::class,

// 'users' => [

// 'driver' => 'database',

// 'table' => 'users',

// ],

2)Router web.php

Route::get('login', array(

'uses' => 'UserController@showLogin'

));

Route::post('login', array(

'as' => 'login',

'uses' => 'UserController@doLogin'

));

Route::get('logout', array('uses' => 'UserController@doLogout'));

// hem de qrup seklinde hansi sehfelere ancaq login olmus user gore biler gosteririk.

//AuthMidleWare vasitesile

Route::group(['middleware' => 'AuthMiddleWare'], function () {

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

return view('users');

});

Route::post('/createUser','UserController@create');

Route::get('/edit/{id}', 'UserController@edit');

Route::post('edit/update/{id}', 'UserController@update');

});

3)Controllerimiz:

public function showLogin()

{

if (Auth::check()) {

return view('home'); // eger login olubsa login sehfesi evezine home yonlen

}

return view('login');

}

public function doLogout()

{

Auth::logout(); // logging out user

//Session::flush();

return Redirect::to('login'); // redirection to login screen

}

public function doLogin(Request $request)

{

$credentials = [

'email' => $request['email'],

'password' => $request['password'],

//'password' => Hash::make($request['password']),

];

$auth=Auth::attempt($credentials);

//dd($auth);

//dd($credentials);

Session::put('email',$request->email);

Session::save();

if ($auth) {

return Redirect::to('userList');

}

return Redirect::to('login');

}

4)AuthMiddleWare

public function handle($request, Closure $next)

{

if(!Auth::check()){

return redirect('/login');

}

else{

return $next($request);

}

5)Login.blade.php

<html>

<head>

<title>LOGIN</title>

</head>

<body>

</form>

</body>

</html>

7)kemel.php

protected $routeMiddleware = [

'auth' => \Illuminate\Auth\Middleware\Authenticate::class,

'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,

'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,

'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,

'can' => \Illuminate\Auth\Middleware\Authorize::class,

'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,

'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,

'OldMiddleWare' => \App\Http\Middleware\OldMiddleWare::class,

'AuthMiddleWare' => \App\Http\Middleware\AuthMiddleWare::class,

'StartSession' => \Illuminate\Session\Middleware\StartSession::class

];

**** Biz eger logout etsek asagidaki kimi xeta ala bilersiz :

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'remember_token' in 'field list' (SQL: update `users` set `remember_token`"

Bunun qarsiini almaq ucun evvelce php artisan command ile yeni migration yaradiriq

Php artisan make:migration add_remember_token_to_users_table --table=”users”

Daha sonra users cedvelimize remember_token adli yeni column elave edirik

Laravel ile session-a deyer elave etmek , deyer alib sehfeye oturmek

1)Controller

public function doLogin(Request $request)

{

$credentials = [

'email' => $request['email'],

'password' => $request['password'],

//'password' => Hash::make($request['password']),

];

$auth=Auth::attempt($credentials);

session(['email' => $request['email']]);

if ($auth) {

return Redirect::to('userList');

}

return Redirect::to('login');

}

public function getuserList(Request $request)

{

$userList=users::paginate(2);

$userCount=0;

DB::statement('CALL getUserCount(@userCount)', array($userCount));

$results = DB::select('select @userCount as userCount');

$sessionData = $request->session()->all();

$value = session('email');

//dd($value);

return view('users')->with('userList',$userList)->with('userCount',$results[0]->userCount)

->with('sessionData',$value);

}

2)users.blade.php

Laravel cache istifadesi

1)use Cache; elave olunmalidir controllerimize , ve asagidaki cur cache-e elave edib yoxlayib eger cachede varsa ordan goture bilerik neticeni

if (Cache::has('userList'))

{

$userList=Cache::get('userList'); // eger cachede varsa ordan gotururuk

}

else{

$userList=users::paginate(2);

Cache::put('userList', $userList, 1);

}

return view('users')->with('userList',$userList)->with('userCount',$results[0]->userCount)

->with('sessionData',$value);

Burada 3-cu parametr kimi verilen 1 muddeti gosterir . 1 - yeni 1 deqiqe

Cache::forever - eger qalici olaraq mueyyen muddetlik saxclamaq istemirsizse istifade ede bilersiz.

Cache::forget('userList'); -- eger cache-i silmek isteyirikse

Laravel log istifadesi:

use Log; elave edirkik clasimiza
config->logging.php -de log propertiueleri gosterilir hansi fayla yaziqlacaq ve.s

'single' => [

'driver' => 'single',

'path' => storage_path('logs/laravel.log'),

'level' => 'debug',

'daily' => [

'driver' => 'daily',

'path' => storage_path('logs/laravel.log'),

'level' => 'debug',

'days' => 7,

**** yeni storage papkasinda laravel.log faylina yazilacaq

3) Controllerimiz

Log::debug('---------- getUserList called -----------------');

*** asagidaki metodlari vardir

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

Laravel model relations :

1)Evvelce baza tererfde elaqeni quraq . One to many quracayiq biz

Users cedvelinde id_mobile ve mobile cedvelinde id var.

Relation view-dan asagidaki formada relationu qururuq

**** foreign key-imize index elave elemeyi unutmayin

2)Model classlarimiz:

class mobile extends Model

{

protected $table='mobile';

protected $fillable=['id','number'];

public function users(){

return $this->belongsTo(users::class);

}

class users extends Model implements Authenticatable

{

use AuthenticableTrait;

protected $table='users';

protected $fillable=['name','surname','email','password','id_mobile'];

public function mobile(){

return $this->hasMany(mobile::class);

}

3)Controllerimizde select edek ( mobile-id-si 1 olan userleri getir)

$mobile = DB::table('users')

->join('mobile', 'users.id_mobile', '=', 'mobile.id')

->where('users.id_mobile',2)

->get();
