Create Controller and Request
C:\xampp\htdocs\laravel\laravelproject>php artisan make:controller ProductController -r
laravelproject\app\Http\Controllers\ProductController.php
//laravelproject\app\Http\Controllers\ProductController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Product;
use App\Http\Requests\ProductStoreRequest;
use Illuminate\Support\Str;
use Illuminate\Support\Facades\Storage;
class ProductController extends Controller
{
public function index()
{
// All Product
$products = Product::all();
// Return Json Response
return response()->json([
'products' => $products
],200);
}
public function store(ProductStoreRequest $request)
{
try {
$imageName = Str::random(32).".".$request->image->getClientOriginalExtension();
// Create Product
Product::create([
'name' => $request->name,
'image' => $imageName,
'description' => $request->description
]);
// Save Image in Storage folder
Storage::disk('public')->put($imageName, file_get_contents($request->image));
// Return Json Response
return response()->json([
'message' => "Product successfully created."
],200);
} catch (\Exception $e) {
// Return Json Response
return response()->json([
'message' => "Something went really wrong!"
],500);
}
}
public function show($id)
{
// Product Detail
$product = Product::find($id);
if(!$product){
return response()->json([
'message'=>'Product Not Found.'
],404);
}
// Return Json Response
return response()->json([
'product' => $product
],200);
}
public function update(ProductStoreRequest $request, $id)
{
try {
// Find product
$product = Product::find($id);
if(!$product){
return response()->json([
'message'=>'Product Not Found.'
],404);
}
$product->name = $request->name;
$product->description = $request->description;
if($request->image) {
// Public storage
$storage = Storage::disk('public');
// Old iamge delete
if($storage->exists($product->image))
$storage->delete($product->image);
// Image name
$imageName = Str::random(32).".".$request->image->getClientOriginalExtension();
$product->image = $imageName;
// Image save in public folder
$storage->put($imageName, file_get_contents($request->image));
}
// Update Product
$product->save();
// Return Json Response
return response()->json([
'message' => "Product successfully updated."
],200);
} catch (\Exception $e) {
// Return Json Response
return response()->json([
'message' => "Something went really wrong!"
],500);
}
}
public function destroy($id)
{
// Detail
$product = Product::find($id);
if(!$product){
return response()->json([
'message'=>'Product Not Found.'
],404);
}
// Public storage
$storage = Storage::disk('public');
// Iamge delete
if($storage->exists($product->image))
$storage->delete($product->image);
// Delete Product
$product->delete();
// Return Json Response
return response()->json([
'message' => "Product successfully deleted."
],200);
}
}
Next, create a Request C:\xampp\htdocs\laravel\laravelproject>php artisan make:request ProductStoreRequest
laravelproject\app\Http\Requests\ProductStoreRequest.php
//laravelproject\app\Http\Requests\ProductStoreRequest.php
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class ProductStoreRequest extends FormRequest
{
public function authorize()
{
//return false;
return true;
}
public function rules()
{
if(request()->isMethod('post')) {
return [
'name' => 'required|string|max:258',
'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
'description' => 'required|string'
];
} else {
return [
'name' => 'required|string|max:258',
'image' => 'nullable|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
'description' => 'required|string'
];
}
}
public function messages()
{
if(request()->isMethod('post')) {
return [
'name.required' => 'Name is required!',
'image.required' => 'Image is required!',
'description.required' => 'Descritpion is required!'
];
} else {
return [
'name.required' => 'Name is required!',
'description.required' => 'Descritpion is required!'
];
}
}
}
Routes All API requests will need the header Accept: application/json.
open routes/api.php and update the following code
laravelproject\routes\api.php
//laravelproject\routes\api.php
<?php
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ProductController;
Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
return $request->user();
});
Route::get('products', [ProductController::class, 'index']);
Route::get('products/{id}', [ProductController::class, 'show']);
Route::post('products', [ProductController::class, 'store']);
Route::put('products/{id}', [ProductController::class, 'update']);
Route::delete('products/{id}', [ProductController::class, 'destroy']);
//resource route
//Route::resource('products', ProductController::class);
