Adaugarea unei inregistrari
in db in sens Laravel
(cu validare)

Adaugarea de inregistrari in tabela
Editati fisierul /app/Http/routes.php astfel:
<?php
use AppFlower;
Route::get('flowers', 'FlowersController@index');
Route::get('flowers/add', 'FlowersController@add');
Route::get('flowers/{nume}', 'FlowersController@show');
?>

Atentie!!!
• Daca veti edita fisierul routes.php astfel:
<?php
use AppFlower;
Route::get('flowers', 'FlowersController@index');
Route::get('flowers/{nume}', 'FlowersController@show');
Route::get('flowers/add', 'FlowersController@add');
?>
veti obtine o eroare deoarece framework-ul va astepta un {nume} de
inregistrare existent, dupa “flowers” in adresa.
Este foarte importata ordinea regulilor de rutare in routes.php!

Vederea
• Vom crea vederea: /resources/views/flowers/addflower.blade.php<html>
<html>
<head><title>Add a flower</title></head>
<body>
<?php
echo Form::open(array('action' => 'FlowersController@store')) ;
echo Form::label('nume', 'Nume: ');
echo Form::text('nume')."<br><br>";
echo Form::label('marime', 'Marime: ');
echo Form::text('marime')."<br><br>";
echo Form::label('culoare', 'Culoare: ');
echo Form::text('culoare')."<br><br>";
echo Form::label('pret', 'Pret: ');
echo Form::text('pret')."<br><br>";
echo Form::submit('Add flower');
echo Form::close();
?>
</body>
</html>

• In acest moment codul formei generate este:
<!DOCTYPE html>
<html>
<head><title>Add flower</title></head>
<body>
<h1>Add a flower</h1>
<form method="POST" action="http://localhost/laravelproj/public/flowers/add" accept-charset="UTF-8"><input
name="_token" type="hidden" value="XYzPAmsxqLSPejkCJlou9PohMyKvQy1i18mVhfvg">
<label for="nume">Nume: </label>
<input name="nume" type="text" id="nume"><br/><br/>
<label for="culoare">Culoare: </label>
<input name="culoare" type="text" id="culoare"><br/><br/>
<label for="marime">Marime: </label>
<input name="marime" type="text" id="marime"><br/><br/>
<label for="pret">Pret: </label>
<input name="pret" type="text" id="pret"><br/><br/>
<input type="submit" value="Add flower">
</form>
</body>
</html>

• Adaugati metoda FlowersController::add
public function add(){
return view('flowers.addflower');
}

Se observa ca forma va trimite implicit datele in pagina /flowers/add. Pentru a
modifica aceasta adresa, vom scrie:
echo Form::open(['url'=>'flowers']) ;
Pentru a trimite datele direct in metoda unui controller, vom modifica forma
addflower astfel:
echo Form::open(array('action' => 'FlowersController@store'))
;
In acest caz trebuie adaugata si ruta in routes.php astfel:
Route::any('flowers/store', 'FlowersController@store');
si deasemenea vom defini metoda store in FlowersController:
public function store(){
return 'Datele nu au fost inserate inca :)';
}

• Pentru a putea gestiona datele trimise de forma in metoda controller-
ului, va trebui sa modificam codul controller-ului astfel:
Inlocuiti linia
use IlluminateHttpRequest;
cu linia:
use Request;
apoi va trebui sa editam metoda store astfel:

$var=Request::all();
return $var;
}
Daca vom dori sa afisam doar numele, vom scrie:
$nume = Request::input('nume');
return $nume;
}

• Pentru a salva datele in tabela, vom edita metoda store in controller
astfel:
$flower=new Flower;
$flower->nume=Request::input('nume');
$flower->marime=Request::input('marime');
$flower->culoare=Request::input('culoare');
$flower->pret=Request::input('pret');
$flower->save();
return redirect('/flowers');
}

Validarea datelor (metoda1– validarea in
controller)
• Info: http://laravel.com/docs/5.0/validation
Editati metoda store din /app/Http/Controllers/FlowersController astfel:
$validator=Validator::make(Request::all(), [
'nume'=>'required',
'culoare'=>'required',
'marime'=>'required',
'pret'=>'required'
]);
if($validator->fails()) return 'failed validation';
$flower=new Flower;
$flower->save();
}

• Daca veti incerca sa vizualizati
• http://localhost/paravelproj/public/flowers/add si apoi incercati sa inserati o
inregistrare vida, veti obtine o eroare deoarece nu va fi “vazuta” clasa
Validator.
• Pentru a elimina eroarea puteti utiliza metodele:
METODA1: Adaugati linia: use Validator; in controllerul FlowersController sau
METODA2: Scrieti codul validatorului asttfel:
$validator=Validator::make(Request::all(), [
'nume'=>'required',
'pret'=>'required'
]);
Apoi veti obtine output-ul:

• Pentru a verifica fiecare camp separat si a afisa mesaje de eroare specifice, vom edita validarea din metoda
store astfel:
$validation=Validator::make(Request::all(), [
'nume'=>'required',
'pret'=>'required'
]);
if($validation->fails()){
return redirect()->back()->withInput()->withErrors($validation->messages());
}
$flower=new Flower;
$flower->save();
}

• Editati si vederea /resources/views/flowers/addflower.blade.php astfel:
<!DOCTYPE html>
<html>
<head><title>Add a flower</title></head>
<body>
<?php
echo Form::open(array('action' => 'FlowersController@store')) ;
echo Form::label('nume', 'Nume: ');
echo Form::text('nume');
echo $errors->first('nume')."<br/><br/>";
echo Form::label('marime', 'Marime: ');
echo Form::text('marime');
echo $errors->first('marime')."<br/><br/>";
echo Form::label('culoare', 'Culoare: ');
echo Form::text('culoare');
echo $errors->first('culoare')."<br/><br/>";
echo Form::label('pret', 'Pret: ');
echo Form::text('pret');
echo $errors->first('pret')."<br/><br/>";
echo Form::submit('Add flower');
echo Form::close();
?>
</body>
</html>Daca veti incerca sa adaugati o interistrare vida http://localhost/paravelproj/public/flowers/add , veti obtine:

Eliminarea erorii: No supported encrypter found.
The cipher and / or key length are invalid.
In fereastra de comanda scrieti:
php artisan key:generate

Validarea datelor (metoda2– validarea in
model)
• In acest caz, editati fisierul model /app/Flower.php astfel:
<?php namespace App;
use IlluminateDatabaseEloquentModel;
class Flower extends Model {
protected $fillable=['nume','marime','culoare','pret'];
public $timestamps=false;
protected $table = 'flowers';
public static $rules=[
'nume'=>'required',
'pret'=>'required'
];
}

• Deasemenea editati metoda store din controllerul FlowersController astfel:
$validation=Validator::make(Request::all(),Flower::$rules);
if($validation->fails()){
return redirect()->back()->withInput()->withErrors($validation->messages());
}
$flower=new Flower;
$flower->save();
}
Daca veti incerca sa adaugati o interistrare vida
http://localhost/paravelproj/public/flowers/add , veti obtine:

• Pentru a face validarea numai in model, editati modelul Flower.php:
<?php namespace App;
use IlluminateDatabaseEloquentModel;
use Validator;
class Flower extends Model {
public static $errors;
protected $fillable=['nume','marime','culoare','pret'];
public $timestamps=false;
protected $table = 'flowers';
public static $rules=[
'nume'=>'required',
'pret'=>'required'
];
public static function isValid($data){
$validation=Validator::make($data,static::$rules);
if($validation->passes()) return true;
static::$errors=$validation->messages();
return false;
}
}
?>

• In acest caz metoda store din controller devine:
if(!Flower::isValid(Request::all())){
return redirect()->back()->withInput()->withErrors(Flower::$errors);
}
$flower=new Flower;
$flower->save();
}
