Validation Strategies & Route Group

Here we deal with the validation with 2 methods inside the store function which will be invoked when the user wants to create the new Product.

• Using default Request $request dependency injection and invoke the validate method.

  public function store(Request $request)
    {
        // If validation fails it will redirect back to same form.
        $request->validate([
            'name' => 'required',
            'price' => 'required|decimal',
        ]);

      Product::create([
            'name' => $request->name,
            'price' => $request->price,
            'category_id' => $request->category_id,
            'description' => $request->description,
            'photo' => ''
        ]);
        return redirect()->route('products.index');
    }

• Create the Request class with artisan and inside the method of this class named rules define all your validation rules and used this as a dependency injection inside the store function.

php artisan make:request StoreProductRequest

class StoreProductRequest extends FormRequest
{
    public function authorize()
    {
        return true;
    }

    public function rules()
    {
        return [
            'name' => 'required',
            'price' => 'required|decimal',
        ];
    }
}

  public function store(StoreProductRequest $request)
    {
     
        Product::create([
            'name' => $request->name,
            'price' => $request->price,
            'category_id' => $request->category_id,
            'description' => $request->description,
            'photo' => ''
        ]);
        return redirect()->route('products.index');
    }
